Act: Run docker fails: docker: command not found

[dfreilich]

When I try to run docker commands locally, it seems to fail.

name: test

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest
    name: Test Registry
    steps:
      - name: Checkout Action
        uses: actions/checkout@v2
      - name: Run local registry
        run: docker run -d -p 5000:5000 registry:2

Fails for

test/Pack Local Build] ⭐  Run Run local registry
| /github/workflow/1: line 2: docker: command not found
[test/Pack Local Build]   ❌  Failure - Run local registry

The same file works on Github Actions.

This might sound silly but do you have docker installed on the machine you're running act on?
And if so can you run docker in a terminal and it works?

[dfreilich]

Yup, I do.

[MaxNamazov]

I run into the same issue

[hsblhsn]

I got the same issue!

[keeefin]

Same here

[hsblhsn]

Got a hotfix for my problem.

I downgraded to docker/build-push-action@v1 in my action file. It worked!

I added a fake step:
apt-get update && apt-get install docker.io -y
and got it working, fair enough to test my action locally, you will need to remove that step before committing.

If you don't mind pulling the big docker image then, as the docs say, you can do:

act -P ubuntu-latest=nektos/act-environments-ubuntu:18.04

[github-actions[bot]]

Issue is stale and will be closed in 7 days unless there is new activity

[artis3n]

Would love there to be some intermediary image between node-slim and nektos/act-environments-ubuntu:18.04 that suffices for act, does anyone know of one?

[artis3n]

Update: I made ghcr.io/artis3n/docker-node:latest

It has docker, node, npm, and yarn.
https://github.com/artis3n/docker-node

Am using it successfully in a private repo so I can't link:

act -j job -P ubuntu-latest=ghcr.io/artis3n/docker-node:latest

with a github action workflow step that looks like:

- name: The Thing
  uses: docker://theimageIwantToUse:version
  with:
    entrypoint: cmd
    args: args to the --cmd

Works great

[dfreilich]

Thanks for all the suggestions, and the smaller image @artis3n ! I'm going to close the issue, given the two valid options.
