Mirko Sekulic f2b4dbf05f run docker step in host mode (#857)
## Problem
In host executor mode, uses: docker://<image> step actions fail because
act/runner/step_docker.go always attaches the step container to the job
container's network namespace, which doesn't exist in host mode.

### Example
Run following job in host runner

```yaml
jobs:
  test:
    runs-on: ubuntu-latest-host
    steps:
      - uses: docker://alpine:3.20
        with:
          args: echo hello
```
```
Error:
  failed to start container: Error response from daemon:
    joining network namespace of container:
    No such container: xxxxxx
```

This pr allows the docker step in the host mode

## Testing
I tested following steps on host runner and it worked

```yaml

 - name: Test azure cli action in host mode
   uses: azure/cli@v2
   env:
     RUNNER_OS: Linux
   with:
     inlineScript: echo "hello from azure cli"
 
 - uses: docker://alpine:3.20
   with:
     args: echo hello

```

act runner

Act runner is a runner for Gitea.

Installation

Prerequisites

Docker Engine Community version is required for docker mode. To install Docker CE, follow the official install instructions.

Download pre-built binary

Visit here and download the right version for your platform.

Build from source

make build

Build a docker image

make docker

Quickstart

Actions are disabled by default, so you need to add the following to the configuration file of your Gitea instance to enable it:

[actions]
ENABLED=true

Register

./act_runner register

And you will be asked to input:

  1. Gitea instance URL, like http://192.168.8.8:3000/. You should use your gitea instance ROOT_URL as the instance argument and you should not use localhost or 127.0.0.1 as instance IP;
  2. Runner token, you can get it from http://192.168.8.8:3000/admin/actions/runners;
  3. Runner name, you can just leave it blank;
  4. Runner labels, you can just leave it blank.

The process looks like:

INFO Registering runner, arch=amd64, os=darwin, version=0.1.5.
WARN Runner in user-mode.
INFO Enter the Gitea instance URL (for example, https://gitea.com/):
http://192.168.8.8:3000/
INFO Enter the runner token:
fe884e8027dc292970d4e0303fe82b14xxxxxxxx
INFO Enter the runner name (if set empty, use hostname: Test.local):

INFO Enter the runner labels, leave blank to use the default labels (comma-separated, for example, ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest):

INFO Registering runner, name=Test.local, instance=http://192.168.8.8:3000/, labels=[ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest ubuntu-22.04:docker://docker.gitea.com/runner-images:ubuntu-22.04 ubuntu-20.04:docker://docker.gitea.com/runner-images:ubuntu-20.04].
DEBU Successfully pinged the Gitea instance server
INFO Runner registered successfully.

You can also register with command line arguments.

./act_runner register --instance http://192.168.8.8:3000 --token <my_runner_token> --no-interactive

If the registry succeed, it will run immediately. Next time, you could run the runner directly.

Run

./act_runner daemon

Run with docker

docker run -e GITEA_INSTANCE_URL=https://your_gitea.com -e GITEA_RUNNER_REGISTRATION_TOKEN=<your_token> -v /var/run/docker.sock:/var/run/docker.sock --name my_runner gitea/act_runner:nightly

Configuration

You can also configure the runner with a configuration file. The configuration file is a YAML file, you can generate a sample configuration file with ./act_runner generate-config.

./act_runner generate-config > config.yaml

You can specify the configuration file path with -c/--config argument.

./act_runner -c config.yaml register # register with config file
./act_runner -c config.yaml daemon # run with config file

You can read the latest version of the configuration file online at config.example.yaml.
