Enable Updating GitHub Environment Variables via GitHub Actions Workflow

 To update environment  variables defined in GitHub environment, via a GitHub action workflow we cannot use the default GITHUB_TOKEN .

✅ GITHUB_TOKEN can interact with repository contents (depending on permissions), create releases, comment on PRs, update issues, etc.

❌ GITHUB_TOKEN cannot update repository environments, environment secrets, or environment variables via the GitHub REST API.

Environment Deployment Approvals for GitHub Action Workflow

 In GitHub actvaions workflows we can use environments to scope varibles and protection rules. Let's compare Azure DevOps pipeline environments to GitHub Actions workflow environments, differences regarding environment deployment approvals, in this post.

An environment can be configured for approvals as shown below.

Code for Creating a Multi Stage Workflow Structure with GitHub Actions - Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 3

 In the previous post "Create Multi Stage Pipeline Structure with GitHub Actions - The Layout - Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 2" we have dicussed the GitHub action workflow layout mapping to the Azure pipeline structure. The code for workflows can be structured as shown below for the pipeline requirement discussed in "Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 1". Note that we have seperated folder structure for job actions and step actions to organize the code properly in a manageable way. However, both are really composite actions in GitHub. Each action name is setup using a folder name as it must be action.yml or action.yaml for actions.

Create Multi Stage Workflow Structure with GitHub Actions - The Layout - Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 2

 In "Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 1" we have discussed the limitation of GitHub action workflows compared to Azure DevOps pipelines. Further, we have compared the features and possible mappings. In this post, let's try how we can create GitHub workflow structure to make it similar to Azure DevOps pipeline shown in "Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 1".

Lets now look at the a the outcome of GitHub workflow setup, and see how it maps to Azure pipeline structure above creating the below pipeline stages.

GitHub Workflow

Note that unlike below fully functional Azure pipeline here in GitHub workflow is only having the structure created only. No approval gates setup or actual steps of execution implemented. But structure is setup keeping the real working workflow in mind. The intialize stage in Azure pipeline publishes AKS manifest files as artifacts in same pipeline, to be used in pepeline jobs, without full repo checkout. However, this is intentionally skipped in GitHub workflow as it seems checkout in every job is required to get the actions and jobs to be executed in GitHub workflow.

Mapping Azure DevOps Multi-Stage Pipelines to GitHub Actions - Part 1

 Migrating from Azure DevOps to GitHub Actions is mostly about rethinking stages → jobs, and stage dependencies → job dependencies (needs) while keeping environments and deployment isolation intact. This is a bit challanging task as GitHub actions does not support independant varaible groups and environments as in Azure DevOps. In this post let's look at  how a classic multi-stage deployment flow can be represented cleanly in GitHub Actions.

The Source Azure DevOps pipline can be a single env deployment such as below.

Publish Ascii Documentation to Confluence via Azure Pipelines

We can use AsciiDoc to write technical documentation. However, confluence is a popular wiki to keep the documentation related to software projects. In this blog let's look at how to publish AsciiDoc documentation in a repo to Confluence via Azure DevOps pipelines.
