Workflows ¶

The GitHub Actions deployment workflow configuration lives at .github/workflows/deploy.yml.

Info

The entire process from GitHub commit to full redeploy of the application can take from around 5 minutes to 10 minutes or more depending on the deploy environment. Have patience!

Deployment steps ¶

The workflow is triggered with a push to the corresponding branch. It also responds to the workflow_dispatch event to allow manually triggering via the GitHub Actions UI.

When a deployment workflow runs, the following steps are taken:

1. Checkout code ¶

From the tip of the corresponding branch (e.g. dev)

2. Authenticate to GHCR ¶

Using the github.actor and built-in GITHUB_TOKEN secret

3. Build and push image to GitHub Container Registry (GHCR) ¶

Build the root Dockerfile, tagging with both the branch name (e.g. dev) and the SHA from the HEAD commit.

Push this image:tag into GHCR.

4. App Service deploy ¶

Each Azure App Service instance is configured to listen to a webhook from GitHub, then deploy the image.
