Run development version of dagger?

[Solomon Hykes]

My plan requires a patched version of dagger. I want to run it in a github workflow, but since it runs the latest official release by default (currently 0.2.0), my patch is not included. How can I configure dagger-for-github to run my patched version of dagger?

Example that doesn't use dagger-for-github:
https://gist.github.com/maert/47cc6b3a30ed3f0efc650ac88ba47e03

If the interface is good, could be made into action inputs with the dagger executable put in an appropriate spot in PATH.

This is what I ended up doing for the todoapp, before 0.2.0 was released: https://github.com/dagger/dagger/blob/c3f21958d2d64ca6da2704b6b1f644d46802def0/.github/workflows/todoapp.yml

I definitely think that we should support this in the action.

Thanks, I'm trying to run this but the action fails with "Error: Input required and not supplied: token"

• How do I provide the missing input?
• Is there a way to require no input, for example by using the credentials already available to the GHA runner by default?

Disclaimer: I am a GHA noob.

Here is my workflow, in case it's helpful:

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

env:

        with:
          repository: ${{ github.event.inputs.dagger-repo }}
          path: 'src/dagger'
          ref: main
          token: ${{ secrets.GH_PAT }}
          fetch-depth: 0
      
      # get SHA hash in case branch or tag was used for checkout

Update: I removed the line setting an explicit token (token: ${{ secrets.GH_PAT }}) in the hope that it would use a default token. It appears to have worked, now I fail a bit later at "build dagger":

Run cd /home/runner/work/shykes/shykes/src/dagger
[8](https://github.com/dagger/shykes/runs/5579280314?check_suite_focus=true#step:6:8)
make: *** No rule to make target 'dagger'.  Stop.
[9](https://github.com/dagger/shykes/runs/5579280314?check_suite_focus=true#step:6:9)
Error: Process completed with exit code 2.

I thought maybe make is being run in the wrong directory, but I don't know how to troubleshoot this.

How do I provide the missing input?

In the example above, notice secrets.GH_PAT. You need to create a secret called GH_PAT.

I refined things and made an actual resuable lego brick, an action, here:
https://github.com/maert/build-dagger-github-action/blob/main/action.yml#L4-L15

In this one, the inputs are similar, but I make the repo-token optional and give good defaults for the other two required inputs.

You can use the action like this to install dagger from dagger/dagger and main branch:

name: Build dagger workflow

on: [push]

jobs:
  build-dagger:
    runs-on: ubuntu-latest

    steps:      
      - uses: maert/build-dagger-github-action@v1.3

A more complete example that performs a checkout out of the repo (with a dagger cue file in it), builds dagger from source at a particular git commit in my fork, and then runs a dagger do here: https://github.com/maert/test-action/blob/main/.github/workflows/test.yml

Nice job @maert! 🙌🏻

I am keen on folding it into this repository. I expect this to remain in my swap for a few weeks, but I intend to come back to it.

Thank you both for your help! I got it to work on my repo.

My 2c on how to implement this feature:

• We already have a version field
• The version field could be extended in the following way: if its value is a URL, the dagger binary is downloaded from that URL instead of the default release URL and added to the PATH.

This has the advantage of limiting proliferation of custom builds of dagger, which is a subtle form of DX fragmentation. For example if we change our build tool from make to dagger, we don't want to deal with outdated GHA configurations that still run make.

Short term, each user can build their own binary and publish it anywhere: github, s3 etc.

Longer term, we can (and IMO should) host a binary-on-demand service eg. get.dagger.io/binary/dagger-$GITREF.tgz that builds the requested version just-in-time for download.

We have something like this with our setup-buildx-action. You can define a git repo as version and it will build on-fly buildx and use it: https://github.com/docker/setup-buildx-action/runs/5987865407?check_suite_focus=true#step:3:95

        name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v1
        with:
          version: https://github.com/docker/buildx.git#refs/pull/731/head

It's quite powerful when you want to test a PR with a specific context. Under the hood it uses a Git remote context to build buildx with buildx 😅:

docker buildx build --target binaries --output type=local,dest=/tmp/docker-setup-buildx-8FFA7Y/out https://github.com/docker/buildx.git#refs/tags/v0.5.1

Doing something like this should be possible for dagger too. Here is the PR for ref: docker/setup-buildx-action#99

This is great! Thank you!

#53 should fix this issue but depends on dagger/dagger#2288 if we want to build from the default branch.

In the meantime you can try with:

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      -
        name: Checkout
        uses: actions/checkout@v3
      -
        name: Dagger
        uses: crazy-max/dagger-action@build-ref
        with:
          version: https://github.com/dagger/dagger.git#refs/pull/2288/head
          cmds: do test

@crazy-max You save my life!

I have mirgated to dagger with my PR now dagger/dagger#2310 (https://github.com/octohelm/cuemod)
