Our app will be hosted on the BCGov Private Cloud space, on the Kamloops Gold Cluster.

Team:

  • DevOps Lead: Noel Feliciano nofelici

  • Development (including Workflow changes): Chelsea Brown cbrown

  • Product Manager/Owner (Openshift): Dea De Jarisco

Here, there are 4 projects, including three environments (dev, test, prod) and tools. Tools will be responsible for handling the build config and building the application out, while each build will be promoted to each environment through a deployment config.

GitHub Workflows

Our workflows on GitHub include the following:

  • On PR, build the application and handle some minimal automated testing, including code quality analysis

  • On merge, automatically deploy the main branch to dev

  • We can then deploy to test by using make tag-test on a specific commit

  • After QA finishes testing on test, we can deploy and tag for prod at any point. This requires approvals before it finishes deployment

 

Building and Deployment

What happens behind the scenes:

  • tools Project on Openshift contains a build configuration each for server and client that watches the repository and watches for a push to the main branch. When a commit is pushed to main, it kicks off a build

  • After the build is concluded, it pushes an Image into the ImageStream in tools with the tag based on the commit SHA

  • dev Project on Openshift contains a deployment configuration each for server and client that watches for the tag dev in the image stream. When the tag is pushed, the deployment config is kicked off and promotes the published image into the dev environment

  • test Project on Openshift contains a similar DC for the tag test

  • prod Project on Openshift contains a similar DC for the tag prod

  • As such, in order to deploy, we have make commands that pushes a git tag and an openshift (oc) tag for the three environments. Running the oc tag will tag the image tagged with the commit we are tagging from to the environment we are tagging to and kick off the right DC

Other Openshift Pods

We also have a number of pods for patroni, which manages our postgres database. There are notes on how this works in the application readme, and notes on how it works in general on the BCGov GitHub

Another pod exists for backups for patroni, notes can be found on GitHub
