What is the Illuminate Integration Gateway?

The Illuminate Integration Gateway, also called the Dataport, is a tool used to provide the Illuminate platform with access to data that is located in physically and logically secure configurations, such as behind a firewall in the organization’s data center. The Integration Gateway provides a secure, encrypted channel to transport this data to the Illuminate cloud environment, where Illuminate creates a secure Application Program Interface (API) access platform.

How it works

N2N provides a Docker container that runs Illuminate's Integration Gateway (IIG). This is installed on a Virtual Machine (VM) that is provided by the University and typically hosted on the University's network. The IIG is used to facilitate secure communication between the University database and the Illuminate Platform without having to allow direct external communication to the actual database. VM setup is operating system specific, please refer to your onsite System Administrator for VM setup.

What is the current version of the Integration Gateway?

Illuminate Integration Gateway is at Version 4.10

*Note: Prior versions of the Illuminate Integration Gateway were branded "Illuminate Dataport"

What do we provide?

N2N provides a Docker image with the following software packages included:

  • Tomcat 9.0.20
  • JVM 11.0
  • Illuminate Integration Gateway Project 4.10 (the N2N application code)

General System Requirements

General system requirements for installing the Integration Gateway:

Software

  • Docker 17.x version or higher

Hardware (VM)

  • 4 to 8 CPU Cores (processors)

  • 8GB to 16GB RAM

  • Enough disk space to run the OS and other supporting software (recommended disk space 40+ GB)



  • Typically an 8 GB Ram server with 4 Core Processor can serve about 700-800 transactions per second.

  • For more information about Docker, prerequisites visit this Docker page

What is Docker and why does N2N use this?

What is Docker?

Docker is the world's leading software containerization platform. Docker containers wrap a piece of software in a complete file system that contains everything needed to run: code, run time, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment. Containers isolate applications from one another and the underlying infrastructure while providing an added layer of protection for the application.

For more details about Docker please visit this Docker page

What is Docker Compose?

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

.

For more details about docker-compose please visit the Docker Compose page

Why does N2N use Docker for the Illuminate Integration Gateway?

The Docker platform provides N2N with a simple, effective way to deliver the right package of software to the Illuminate Integration Gateway. Docker allows N2N to combine tested versions of software with validated configuration files into one deployment package. This process greatly reduces the number of manual steps, which improves reliability and robustness, as well as making deployment faster!

Detailed instructions for installing Docker & Docker Compose (on CentOS)

Prerequisites

  • An SSL certificate ready (self-signed is not supported) which includes .crt file (the .crt file must have the public, root, and intermediate certs, with public cert on top of the file) and a private key. (See SSL Certs FAQs at the end of this document)

  • Ports 443, 80, 2376 (2376 port is optional) need to be open on the VM instance where Docker and Integration Gateway are installed

  • Get the authorization credentials from N2N to pull the Docker image

Docker Installation

There are two ways to install Docker Engine

  1. Install using the yum package manager (Recommended)
  2. Install using the instruction from https://docs.docker.com/install/linux/docker-ce/centos/

Install with yum

  • Log into your VM as a user with sudo rights to install and manage services or root user. If you are logged in as root you do not need to add the "sudo" at the beginning of each command.
  • Make sure your existing packages are up-to-date using yum
  • Add the yum repository if it doesn’t exist on your server where you are installing Docker.  
  • We will also need to enable the Redhat "extras" repository for RHEL 7 (The third command to enable the Redhat extras repository will only need to be run if you are running RHEL 7).

sudo yum install -y yum-utils 
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum-config-manager --enable rhel-7-server-rhui-extras-rpms
  • Install the Docker package for RHEL 8.  


sudo yum install -y --nobest docker-ce docker-ce-cli containerd.io
  • Install the Docker package for RHEL 7.  


sudo yum install -y docker-ce docker-ce-cli containerd.io
  • Enable the Docker service.  This is needed so docker will start whenever the system is restarted


sudo systemctl enable docker.service
  • Start the Docker daemon


sudo systemctl start docker
  • Verify Docker has been installed correctly by running a test image in a container


sudo docker ps
  • The screenshot below will show the installation is done properly.

Now that Docker installation is complete, the next step is to install Docker compose. 

Docker Compose Installation

  • Run this command to download the current stable release of Docker Compose


sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose



If you have problems installing with curl, see Alternate Installation Options


  • Apply executable permissions to the binary. 


sudo chmod +x /usr/local/bin/docker-compose


.

If the command docker-compose fails after installation, check your path. You can also create a symbolic link to /usr/bin or any other directory in your path

For Example:

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

For more details about Docker Compose, please visit here


  • Test the docker-compose Installation


docker-compose --version 
O/P: docker-compose version 1.24.0, build 1110ad01 it will show docker-compose version


Integration Gateway 
Installation

There are two ways to install Integration Gateway

  1. Installation (Recommended, & detailed in this document)
  2. Install using manual steps (not included in this document)

Prerequisites

  • Firewall rules need to be set up by this time. Whitelist N2N NAT IPs below

.

QA: 23.20.165.255/32

PROD54.204.165.208/32

  • Look at the Appendix-4 for SSL certs setup info
  • We need an FQDN which connects to the Integration Gateway on HTTPS

Authorization to Access Integration Gateway Docker Images


Run the below command on the dataport server using the credentials above docker login 
-u="n2ndevops+User" -p="xxxxxxxxxxxxxxxxxxx" quay.io

Integration Gateway Installation

  • Login as root on to the VM

  • Create a folder with your preferred name


For Example: mkdir n2ndataport
  • Download the docker-compose.yml file which attached to the bottom of this document.

  • Place this docker-compose.yml file in the folder 'n2ndataport' which was created in the above step.
  • Run the docker-compose.yml file to deploy both Nginx and Integration Gateway Docker containers. Use the below command;

docker-compose up -d


.

Once docker-compose up -d is executed:

  • Default Docker network is created with the folder name where the docker-compose.yml file is located (in the screenshot above n2ndataport_default docker network is created based on folder n2ndataport)

  • Then in the next step, it started pulling the Integration Gateway image and Nginx image

  • In the final step, Integration Gateway and Nginx containers are created

The output after running the above command will look like the screenshot below


  • Run docker ps command to view the installed/running containers.

          In the screenshot below, we can see that the Integration Gateway (Dataport) and Nginx containers are up and running.

Applying the SSL Certificate

  • Now copy all your SSL certificate files (such as the .crt and .key files*) to the “certs” folder inside the Nginx container

docker cp <your file name>.crt nginx:/certs/<your file name>.crt docker cp <your file name>.key nginx:/certs/<your file name>.key     


.

File extensions .crt and .key are used as an example, use appropriate valid extensions as needed.

  • FAQ: What type of certificates are we using for connecting to your Integration Gateway?

          We are using X.509 type certificates.

  • FAQ: Should SSL certificates point to the server or docker containers?

          Here SSL certificates should be in relation with host_name or domain name (while generating certificates).

          These certificates should point to the docker containers. Here, in this case, we are placing certificates in the Nginx container. 

  • Login to the Nginx container


docker exec -it nginx bash
  • Open default.conf file:


cd /etc/nginx/conf.d/ vim default.conf



  • Add "ssl" at line 2 as shown below

    • Example: listen 443 ssl;

  • Change server_name to yourdnsname.com at line 3 and 22

  • Uncomment lines 4 and 5 (Note: Do this step after copying certificates to nginx container)

  • wq! (save the configurations)
  • Now test Nginx config using this command (the command checks whether the certificates are valid)


nginx -t
  • If the validation is successful, exit from the nginx container. Otherwise, review the error and return to the Nginx default.conf file


exit
  • Restart the Nginx container


docker restart nginx

Test connection

  • Test the connection using the curl command below. It should return a response: "Not a valid request.”. Note that you need to configure the command below to match your organizational nomenclature.


curl -X GET https://{server_name(or)host_name}/idp

Establishing a connection between Illuminate, Integration Gateway, and the SIS Database

Note: Firewall rules need to set up by this time. Whitelist N2N NAT IPs below

.

QA: 23.20.165.255

PROD54.204.165.208

Step 1 - Adding Integration Gateway URL in Illuminate app

Note: In this step, we will configure the Integration Gateway details in the Illuminate App.

Note: If you do not have an Illuminate account please contact appsupport@n2nservices.com 

  • Configure the Integration Gateway details within the Illuminate App's Connection Module by following below steps
    • From the left-side menu, select the connection button.
    • Next, select Setup Dataport from the list of options
    • Click on GET STARTED
    • Enter the 'Dataport Name' field and the 'Dataport URL' field then click on the publish button on the screen.
      • Note: Dataport Url example looks like https://{server_name(or)host_name}
  • Note: You can also follow the steps from this link Step by Step instructions for Step1
Step 2 - Add the database provider in the Illuminate app

Note: This step is also performed in the Illuminate App.

  • Configure the Database provider details within the Illuminate App's Connection Module using the following steps:
    • From the left-side menu, select Connections.
    • Click the ADD PROVIDER button above the provider list index table
    • Next, under Provider Details select the Provider Type as Database.
    • Select the appropriate database under Provider (i.e Oracle or SQL Server per your SIS).
    • Enter the desired name for Provider Name.
    • Enter a Connection Name for this setup.
    • Enter a description for this connection.
    • Click Save.
    • A popup will appear with authorization details that should be copied and used to run the database curl command in Step 3. 
      • Note: The generated token will expire in 5 mins.
  • Note: You can also follow the steps from this link Step by Step visual instructions for Step 2
Step 3 - Connecting the Integration Gateway to the Database(s)

Note: The instructions below are to be performed on the Integration Gateway Server.

In this step, we will establish the connection between the Integration Gateway and the database by creating a property file.

Note: Within these instructions, EMPDB.properties is used as an example. EMPDB can be replaced with an appropriate database name. The database properties are stored in an encrypted format in EMPDB.properties.

Use the below method to configure the EMPDB.properties:


The properties are generated using a curl command. For security, please turn off Linux history before running the curl command, using the following set command: set +o history
  • The Illuminate Integration Gateway includes a web service that will create these properties in the system.

Step 4 - Creating the request body with the database properties

This service needs a JSON request body as shown below, edit this sample to include your specific database server information for Oracle or SQL Server:


{     "DBHost": "Server hostname or IP", // database host     "port": "1234", // database port     "SID": "", // sid or service name for oracle providers     "ServiceName": "servicename",     "databaseName": "", // databaseName is for SQL server providers     "DBUsername": "name", // DB username or schema Name     "DBPassword": "***********" // DB password }



  • A value should be populated for either SID or ServiceName but not both.
  • Ensure there are no carriage return/line feed (CR/LF) characters in the parameters before running the full curl command.


.

{ "DBHost": "0.0.0.0", "port": "1234", "SID": "", "ServiceName": "servicename", "DBUsername": "username", "DBPassword": "***********" }


.

{ "DBHost": "0.0.0.0", "port": "1234", "databaseName": "", "DBUsername": "username", "DBPassword": "***********" }


.

{ "DBHost": "0.0.0.0", "port": "1234", "databaseName": "", "DBUsername": "username", "DBPassword": "***********","informixServer": "" }

Step 5 - Create & run the CURL command
  • Run the following command to retrieve the Docker container IP (in this case we need the Integration Gateway container port)

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' dataport
  • Replace "dataport_container_ip:port" with the response body from the last step, in the following curl.  invoke the below service (Recommended)

curl -X POST 'https://{dataport_container_ip:port}/idp/addDBproperties' -H 'Authorization:Token from Illuminate connections page in Step 2' -H 'Content-Type: application/json' -d '{"DBHost": "0.0.0.0","port": "1234","SID": "","ServiceName": "servicename","DBUsername": "username","DBPassword": "***********"}'

      (OR)

  • You can also use DNS (which is assigned to the Integration Gateway) to add DB properties file

curl -X POST 'https://{your_dns_name}/idp/addDBproperties' -H 'Authorization:Token from Illuminate connections page in Step 2' -H 'Content-Type: application/json' -d '{"DBHost": "0.0.0.0","port": "1234","SID": "","ServiceName": "servicename","DBUsername": "username","DBPassword": "***********"}'
  • Upon successful connection, you will see the following message

.

{"status":"success","message":"Properties Added"}


.

If the Integration Gateway is on a load-balanced network and you use the DNS method to add the properties it will not update in all the containers. In this case, use the container IP to individually update the properties.


.

Load Balancing the Integration Gateway

Note: Recommended but optional

Load balancing refers to efficiently distributing incoming network traffic across a group of servers. A Load Balancer acts as the "traffic cop" sitting in front of your servers and routing requests across all servers capable of fulfilling those requests in a manner that maximizes speed and capacity utilization and ensures that no one server is overworked, which could degrade performance.If a single server goes down, the load balancer redirects traffic to the remaining online servers. When a new server is added to the server group, the load balancer automatically starts to send requests to it. 


.

If the Integration Gateway is on a load-balanced network, please ensure appropriate steps are followed to update the database properties in all relevant servers/containers. 


.

For general background information, see this article about Load Balancing

Sample load balancing diagram leveraging Docker




Integration Gateway setup for PROD on the same QA host/server

If the client wants to set up a PROD integration gateway on the QA host, they need to follow these steps

  • Create a new docker network



docker network create n2ndataport_prod_default


  • Connect Nginx container to newly created dataport network



docker network connect n2ndataport_prod_default nginx
  • Create prod integration Gateway Docker container



docker run --network=n2ndataport_prod_default --net-alias dataportProd --name dataportProd -it -d quay.io/n2ndevops/illuminatedataport:4.10


  • Uncomment lines from 16-23 in default.conf file

  • Test Nginx configurations

nginx -t
  • Reload Nginx configurations



service nginx reload
  • Test the connection using curl. It should “return a response status as not a valid request”. Note that you need to configure the command below to match organizational nomenclature

curl -X GET https://{server_name(or)host_name}/idp2
  • Now jump to "Establishing a connection between Illuminate, Integration Gateway, and the SIS Database"


.

Optional step to autostart the containers after a server reboot

If a server is rebooted, restarted, or start/restart, the docker engine must be restarted. To accomplish that automatically follow the steps below


1. chkconfig docker on 
2(i). docker update --restart=unless-stopped $(docker ps -q) Note: This command starts all the containers within the docker engine of the server (OR) (ii) docker update --restart=unless-stopped containerID/ContainerName Note: This command will start only the specified container



.

SSL Certs In Dataport/IIG

If a client wants to update SSL certs in Nginx, they can go through these instructions for more details

What is an SSL certificate?

An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates the identity of a website and encrypts information sent to the server using SSL technology. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.

What are Certificate Chains?

A certificate chain (or Chain of Trust) is made up of a list of certificates that start from a server’s certificate and terminate with the root certificate.

What is SSL Certificate Chain Order?

The SSL certificate chain order consists of root certificates, intermediate certificates, and a server’s certificate. Root CAs are a trusted source of certificates. Intermediate CAs are bridges that link the server’s certificate to the root CA.

There are three parts to the chain certificates

  • Server Certificate: The server certificate is issued to the specific domain the user needs coverage for.

  • Intermediate Certificate: Intermediate certificates act as middle-men between the protected root certificates and the server certificates issued out to the public. There will always be at least one intermediate certificate in a chain, but there can be more than one.

  • Root Certificate: A root certificate is a digital certificate that belongs to the issuing Certificate Authority. It comes pre-downloaded in most browsers and is stored in what is called a “trust store.” The root certificates are closely guarded by CAs.

For an SSL certificate to be authenticated by the web browsers, it must be authentic and issued by a trusted certificate authority embedded in the browser’s trusted store. If your SSL certificate isn’t issued by a trusted certificate authority, i.e., if it isn’t issued by a Root CA, then the connecting device or web browser will continue to check if the issuing CA was issued by a root CA. It will keep going back down the SSL certificate chain order to find the root CA. If it finds a root CA, a secure connection will be established. If it doesn’t find a root CA, then the connection will be dropped, and your web browser will display an error message that reads “invalid certificate” or “certificate not trusted.”

How To Update SSL Certs In Dataport

  • Ensure you have a private key

  • Create a full certificate bundle for NGINX using one of the methods below, depending on how your SSL provider delivered the certificates to you.

How To form a bundle .crt file


  • Open up a notepad or any text editor.

  • Copy-paste the Public cert (public should always be on the top of the file)

  • Copy-paste the Intermediate cert

  • Copy-paste the Root cert

  • Now save the file with the desired name(dataport-test-school-edu.crt) within an extension of the .crt

  • You will have to create a .crt(self-signed is not accepted) file and a private key.


(OR)

Example GoDaddy:


cat signed_ssl.crt gd_bundle.crt > dataport-test-school-edu.crt Note: Above gd_bundle assumes both intermediate and root
 

Other SSL providers with a single intermediate certificate:


cat signed_ssl.crt intermediate1.crt root.crt > dataport-test-school-edu.crt

Other SSL providers with multiple intermediate certificates:


cat signed_ssl.crt intermediate1.crt intermediate2.crt root.crt > dataport-test-school-edu.crt


Additional step if the private key is password protected:


.

If your private key is password-protected, we will need to make a copy without that password to use on the NGINX instance. If you run these commands and are not prompted for a passphrase, your SSL key did not have a passphrase. If you are prompted for a passphrase, enter it when prompted.


  • NGINX will not properly restart if the private key is password protected.

  • Hence, run the below command to turn the password-protected to a file.



openssl rsa -in private.key -out dataport-test-school-edu.key



Now you have the bundled cert and private key ready, do the below steps to update these files in the Nginx container:

Step 1:

  • Upload the new cert and the key files to the server

  • Copy the new files to the NGINX Docker container to the certs folder.

sudo docker cp dataport-test.school.edu.key nginx:/certs/dataport-test-school-edu.key 
sudo docker cp dataport-test.school.edu.crt nginx:/certs/dataport-test-school-edu.crt


Step 2:

  • Navigate to the below location

docker exec -it nginx bash vi etc/nginx/conf.d/default.conf


  • You will need to update the following items in the file and save them.

    • Modify the ssl_certificate on line 4 (if you are changing the name of the cert than previous)

    • Modify the ssl_certificate_key on line 5 (if you are changing the name of the cert than previous) 

.
server {
  listen 443 ssl;
  server_name dataport-test.school.edu;
  ssl_certificate /certs/dataport-test-school-edu.crt;
  ssl_certificate_key /certs/dataport-test-school-edu.key;
  underscores_in_headers on;
  add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
  add_header X-Frame-Options DENY;
  location /idp {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $server_name;
    proxy_pass http://dataport:8080/idp;
  }
 
  # if you want to use same host for two environments(TEST. QA and PROD) uncomment this location block and give appropriate container name
 
  #location /idp2{
  #    proxy_redirect off;
  #    proxy_set_header Host $host;
  #    proxy_set_header X-Real-IP $remote_addr;
  #    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  #    proxy_set_header X-Forwarded-Host $server_name;
  #    proxy_pass http://dataport:8080/idp;
  #}
}
server {
  listen 80 default_server;
  listen [::]:80 default_server;
  server_name dataport-test.school.edu;
  return 301 https://$host$request_uri;
}


  • Save the changes in the default.conf file

wq! (ESC)

Step 3: 

  • Test NGINX

nginx -t


If NGINX does not come back as successful, then do not proceed to the restart of NGINX. A successful output looks like this.

.

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful


Step 4:

  • Restart NGINX



service nginx reload


A successful restart of NGINX looks like this


[user@dataport-test ~]$ sudo docker exec -it nginx service nginx reload
[ ok ] Reloading nginx: nginx.
[user@dataport-test ~]$


  • Exit from the container



exit


Step 5: Verify that the NGINX container is running


sudo docker ps 
  • The output should show two containers



[user@dataport-test ~]$ sudo docker ps CONTAINER ID        IMAGE                                     COMMAND                  CREATED             STATUS              PORTS               NAMES 907b970bfd51        quay.io/nginx                             "/docker-entrypoint.…"   2 months ago        Up 6 days                               nginx a4adc7911498        quay.io/n2ndevops/illuminatedataport:4.4  "catalina.sh run"        4 weeks ago         Up 3 weeks (healthy)    0.0.0.0:8081->8080/tcp   dataport [user@dataport-test ~]$ 





Dataport Upgrade - Appendix - 5

Integration Gateway upgrade using manual steps

  • Login to the VM instance as root

  • To pull N2N’s Integration Gateway image from the N2N private repository (quay.io), please enter Docker login credentials that are obtained from Illuminate. 

1) Authorization to Access Integration Gateway Docker Images


Run the below command on the dataport server using the credentials above
docker login quay.io
enter the username (grab the username from Illuminate as in the screenshot)
enter the password (grab the password from Illuminate as in the screenshot)

2) Find and stop the dataport container

  • Use the following command to show the containers running on the docker



docker ps



The container name can be seen by typing in `docker ps` as below. The column name NAMES will let you know the container name.


3) Save the previous version of dataport
  • This command should be used to take the backup. If your dataport container has an alternate name, put that in place of ‘dataport’.

docker rename dataport dataport.bk
  • Do this step to validate/compare any custom changes that might have been done to applicationResources.properties, once the new dataport is installed.

.

>docker exec -it dataport.bk bash

>vi webapps/idp/WEB-INF/classes/applicationResources.properties

>exit


4) Pull and Run N2N's Integration Gateway image.



Your network name in the below command could be different.

  • You can get your network name by inspect command as below (the entry will be in the 'Networks' array - see the image below)

    • `docker inspect nginx` ( nginx is the container name)

Example: Image





docker pull quay.io/n2ndevops/illuminatedataport:4.10 
/* To Run this dataport image */
/*Note: The network name n2ndataport_default should be grabbed some the above note */
docker run --network=n2ndataport_default --net-alias dataport --name dataport -it -d quay.io/n2ndevops/illuminatedataport:4.9.1
Auto Restart the containers
  • This command helps to auto-restart upon server reboot unless manually stopped.

docker update --restart=unless-stopped dataport
  • This command then stops the running dataport container. If your dataport container has an alternate name, put that in place of ‘dataport’.

docker stop dataport.bk (dataport is the container name)



.

When you inspect the docker network the new dataport image and nginx should be in the same “Containers” array as shown below image. If you don’t see them in the same network. Check the note above the run command

  • docker inspect n2ndataport_default




  • Test the connection using curl. It should “return a response status as not a valid request.” Note that you need to configure the command below to match organizational nomenclature


curl -X GET https://{server_name(or)host_name}/idp
OptionalStep: Remove the renamed running container. Dataport is the container name

docker rm dataport.bk
5) Add Database Credentials.
  • Now jump to "Establishing a connection between Illuminate, Integration Gateway, and the SIS Database."
