GitHub: Use Actions to Publish Artifacts

This post is going to take the GitHub Actions Workflow we set up in the last post and add a couple of steps that will provide us with access to our application’s binaries. If you are new to this series the following post will catch you up if needed.

GitHub: Import an Azure DevOps Repo
GitHub: Use Actions to build ASP.NET Core Application

Edit the Workflow

Our first step is to get back to the Workflow we want to edit. At the top of the repo click Actions.

On the left side of the screen select the specific Workflow, .NET Core in this case. Now that the list is filtered to just the Workflow we are interested in select the three dots on the most recent run and then click View workflow file.

On the next screen click the pencil above the Workflow file to edit the Workflow.

Add the end of the file adds a call to the .NET CLI to publish. The following is the full file and the last two lines are the publish step.

name: .NET Core

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/[email protected]
      
    - name: Setup .NET Core
      uses: actions/[email protected]
      with:
        dotnet-version: 3.1.101
 
    - name: Install dependencies
      run: dotnet restore
      
    - name: Build
      run: dotnet build --configuration Release --no-restore
      
    - name: Test
      run: dotnet test --no-restore --verbosity normal

    - name: Publish
      run: dotnet publish

Click the Start commit button and commit the change to the branch of your choice. I committed the change directly to master which triggered the Workflow to run. From the logs of the Workflow, you can see that the publish step executed successfully.

Publish Build Artifacts

Now that we have the two web applications publishing we need a way to get the file for the applications. To do this we are going to use the Upload Artifacts Action. I used the output of the Publish step above to find the path to the publish folder for each application and then used an Upload Artifacts Action for each application. The following are the two steps added to the bottom of our existing Workflow.

- name: Upload WebApp1 Build Artifact
  uses: actions/[email protected]
  with:
    name: WebApp1
    path: /home/runner/work/Playground/Playground/src/WebApp1/bin/Debug/netcoreapp3.1/publish/
    
- name: Upload WebApp2 Build Artifact
  uses: actions/[email protected]
  with:
    name: WebApp2
    path: /home/runner/work/Playground/Playground/src/WebApp2/bin/Debug/netcoreapp3.1/publish/

After checking in the changes let the Workflow run. Once complete if you click on the details of the Workflow run you will see it now has Artifacts that can be downloaded.

Wrapping Up

We now have a Workflow that results in files we could actually deploy on top of verifying that the applications builds and the tests pass. I hope this has given you a good jumping-off point to build your own Workflows. We have only scratched the surface of what can be done with GitHub Actions and I’m looking forward to seeing what else we can do.
