In this guide, we'll run you through installing qTest Manager 9.3 using Docker on separate CentOS/Ubuntu machines with a Load Balancer.

This article only demonstrates how to deploy load balancer for qTest Manager.

  • Read this article to deploy qTest Sessions with load balancing.

Before you Begin

What is included in the Docker-Deployment-4.6 package?

The qTest Docker-Deployment-4.6 includes the following applications. Among those, qTest Manager is the required application, simply specify more application you want to deploy (eligible application is up to your license.)

  • qTest Manager 9.3 includes qtest and its prerequisite applications: postgres, qtestlb
  • qTest Session 4.2.1 includes session and its prerequisite applications: postgres, qtestlb
  • qTest Parameters 2.1.7 includes parameters and its prerequisite applications: mongodb, parameterslb
  • qTest Insights 1.19.1 includes insights and its prerequisite applications: postgres, insightslb, insightsetl
  • qTest Launch 1.3.2 includes launch and its prerequisite applications: postgres, launchlb
  • qTest Pulse 9.1 includes pulse and its prerequisite applications: mongodb, pulselb
  • qTest Scenario 2.0.4 includes pulse and its prerequisite applications: scenariolb

Install qTest Manager with Load Balancer

The sample image below tries to demonstrate how to configure qTest Manager with a load balancer for 4 machines:

  • Machine 1: considered as a cluster, deploy qTest Manager's prerequisite app: postgres, and the shared network drive to store attachments
  • Machine 2: deploy qTest Manager 9.3 (qtest)
  • Machine 3: deploy qTest Manager 9.3 (qtest)
  • Machine 4: deploy qTest Manager's load balancer (qtestlb)

NOTE: Every machine in the cluster requires the following ports to be open: 53 and 6783

Deployment Instructions

Access each of the 4 machines where Docker has been installed using root, or a user which has been added to the Docker user group:

  • Repeat the steps below in all 4 machines.
  • Then configure each machine in sequence (Machine 1, 2, 3, 4)

NOTE:

  • Pre-requisite applications of qTest Manager should be deployed in a separate machine rather than in the same machine with qTest Manager (qtest.)
  • The load balancer application (qtestlb) should be deployed after all other apps get deployed.

Download Docker-Deployment-4.6 Package

$ wget <ENTER DOWNLOAD LINK HERE>

Extract the Package

$ tar -zxf docker-deployment-4.6.tar.gz

Access the Package Directory

 $ cd docker-deployment-4.6

 

Machine 1 (the cluster)

Deploy postgres into Machine 1

  • Specify prerequisite apps: postgres
    $ ./configure --apps "postgres"

Modify the Config File

Modify the configure file to ensure the "datadir" variable point to a shared directory where all 4 machines are able to access.

$ vim profiles/default.in

Start the Deployment

$ ./startup

Set qTest Manager as a Linux Daemon

$ ./shutdown
$ ./install
$ systemctl start qtest

Machine 2

Deploy qtest (qTest Manager 9.3) with HTTP into Machine 2

  • qtest-url: IP of machine 4 (the load balancer)
  • qtest-http: qtest port of machine 4 (the load balancer)
  • cluster: IP of machine 1
  • apps: qtest
$ ./configure --qtest-url "http://<IP of machine 4>:<qtest port of machine 4>" --qtest-http "<qtest port of machine 4>" --cluster "<IP of machine1>" --apps "qtest"
  1. Modify the configure file to ensure the "datadir" variable point to a shared directory where all 4 machines are able to access.
    $ vim profiles/default.in
  2. Start the deployment.
    $ ./startup
  3. After the above command completes successfully, set up qTest Manager as Linux Daemon and start the service.
$ ./shutdown
$ ./install
$ systemctl start qtest

Deploy qtest (qTest Manager 9.3) with HTTPS into Machine 2

  • Specify path to ssl-key, ssl-cert, ssl-ca
  • qtest-url: IP of machine 4
  • qtest-https: qtest https port of machine 4
  • cluster: IP of machine 1
  • apps: qtest
$ ./configure --ssl-key "<SSL Key>" --ssl-cert "<SSL Cert>" --ssl-ca "<SSL CA>" --qtest-url "https://<IP of machine 4>:<qtest https port of machine 4>" --qtest-https "<qtest https port of machine 4>" --cluster "<IP of  machine1>" --apps "qtest"
  1. Modify the configure file to ensure the "datadir" variable point to a shared directory where all 4 machines are able to access.
    $ vim profiles/default.in
  2. Start the deployment.
    $ ./startup
  3. After the above command completes successfully, set up qTest Manager as Linux Daemon and start the service.
    $ ./shutdown
    $ ./install
    $ systemctl start qtest

Machine 3

Deploy qtest (qTest Manager 9.3) with HTTP into Machine 3

  • qtest-url: IP of machine 4 (the load balancer)
  • qtest-http: qtest port of machine 4 (the load balancer)
  • cluster: IP of machine 1
  • apps : qtest
$ ./configure --qtest-url "http://<IP of machine 4>:<qtest port of machine 4>" --qtest-http "<qtest port of machine 4>" --cluster "<IP of Machine 1>" --apps "qtest"
