Using -P platform with local image

[dannystaple]

Act version

0.2.42

Feature description

I would like to be able to use a local image for the -P flag. For example:

act --eventpath myevent.json \
  -P ubuntu-latest=my-local-latest

The intent would be to take the medium image and add other parts I might need, for example the python components if the intent is to test pipelines around the python ecosystem.

Currently running this, it will force pull from a remote on dockerhub, however, this may simply be a local image that I do not intend to put onto dockerhub.

Use --pull=false. The reason that this flag now defaults to true is a breaking change in act with older default docker images.

You have to manually keep uptodate, if you use this flag.

Worked a treat - just updating the docs to reflect that.

Hey, the flag doesn't work for me if I never uploaded the image to Docker Hub....

Steps to reproduce:

• Create Docker image locally and give repository name (foobar/docker-github-actions-runner)
• Run this:

  act --container-architecture linux/arm64/v8
  --pull=false
  -P ubuntu-latest=foobar/docker-github-actions-runner
  -P self-hosted=foobar/docker-github-actions-runner

  Returns: Error: Error response from daemon: pull access denied for foobar/docker-github-actions-runner, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

Do I make a mistake with the flags or the feature doesn't exist?

I cannot reproduce your error. You should see forcePull=false in the log and if act finds you image it will use it.

forcePull=true will always pull the image (--pull) forcePull=false will pull the image if missing (--pull=false)

@joanrodriguez I take it the line continuation characters are not posted just for aesthetics or that this was all on one line? Can you show the docker image in docker list. It isn't looking for a local arm64 image when you have a x86 image is it?

[joanrodriguez]

Hey guys, I had some conflicting stuff in my .~/.actrc. After emptying it and removing the architecture arg, I'm able to use a local docker image :)

You can't really tell that it didn't pull it from the logs but it was instantaneous and I had deleted the Docker image from the hub so it definitely worked :)

Thanks again

Hey, the flag doesn't work for me if I never uploaded the image to Docker Hub....

Steps to reproduce:

• Create Docker image locally and give repository name (foobar/docker-github-actions-runner)
• Run this:

  act --container-architecture linux/arm64/v8
  --pull=false
  -P ubuntu-latest=foobar/docker-github-actions-runner
  -P self-hosted=foobar/docker-github-actions-runner

Returns: Error: Error response from daemon: pull access denied for foobar/docker-github-actions-runner, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

Do I make a mistake with the flags or the feature doesn't exist?

I was getting this error too, then realised I needed to add the tag as well as repository name. my-self-hosted-image:v1 now I can run act -j my_github_workflow -P self-hosted=my-self-hosted-image:v1 --pull=false

[dgrebb]

The only question that wasn't answered here, which ended up being the issue for me:

act --container-architecture linux/amd64 --pull=false -P ubuntu-latest=custom-image-name:latest ...

This will look for that image in the specific architecture.

If your custom image wasn't build with that architecture, act will then attempt to pull an image from the registry, even with the --pull=false flag set.

@dannystaple this issue and your subsequent comment saved me days of banging my head against a wall. Thank you!

I needed to docker buildx build --platform linux/amd64 my custom image.

--pull=false doesnt work with me.

[deployment/Deployment/build-and-deploy]   🐳  docker pull image=self-hosted-workers-prod:latest platform= username= forcePull=false
[deployment/Deployment/build-and-deploy] [DEBUG]   🐳  docker pull self-hosted-workers-prod:latest
[deployment/Deployment/build-and-deploy] [DEBUG] Image exists? false
[deployment/Deployment/build-and-deploy] [DEBUG] pulling image 'docker.io/library/self-hosted-workers-prod:latest' ()
Error: Error response from daemon: pull access denied for self-hosted-workers-prod, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

Im building image with --platform linux/amd64 as suggested above but its still trying to pull.

Im also able to run a container with said image:

docker run -it self-hosted-workers-prod:latest /bin/bash

Feels like my flag is being ignored. Using act version : 0.2.65

Any one have the same issue?
