Integrate Dagger with GitHub Actions

caution

This documentation is for an older version of Dagger, which is no longer actively maintained.

We encourage you to upgrade and refer to the documentation for the most current version.

If you cannot upgrade to the latest version, please contact us in the help forum on Discord. When contacting us, please let us know why you cannot move to the latest version. From there, our team will work with you on your use case.

This tutorial illustrates how to use GitHub Actions and Dagger to build, push and deploy Docker images to Cloud Run.

Prerequisites​

We assume that you've finished our 106-cloudrun tutorial as this one continues right after.

Setup new GitHub repo​

Push existing examples/todoapp directory to your new GitHub repo (public or private). It should contain all the code from https://github.com/dagger/examples/tree/main/todoapp, gcpcloudrun and .dagger/env/gcpcloudrun/ directory.

Add GitHub Actions Secret​

Dagger encrypts all input secrets using your key stored at ~/.config/dagger/keys.txt. Copy the entire line starting with AGE-SECRET-KEY- and save it to a GitHub secret named DAGGER_AGE_KEY. In case you don't know how to create secrets on GitHub take a look at this tutorial.

Create a GitHub Actions Workflow​

Create .github/workflows/gcpcloudrun.yml file and paste the following code into it:

.github/workflows/gcpcloudrun.yml
name: CloudRun

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Dagger
        uses: dagger/dagger-for-github@v3
        with:
          age-key: ${{ secrets.DAGGER_AGE_KEY }}
          args: up -e gcpcloudrun

Run​

On any push to main branch this workflow should run and deploy the todoapp to your GCP Cloud Run instance.
