Previously, capacity=N spawned N independent polling goroutines, each making FetchTask RPCs to the Gitea server concurrently. This caused unnecessary connection load on the server proportional to the runner's capacity setting. Replace the N-goroutine model with a single polling loop that uses a buffered channel as a semaphore to control concurrent task execution. The poller acquires a capacity slot before fetching; when at capacity, it blocks without issuing RPCs. Fetched tasks are dispatched to independent goroutines that release their slot on completion. Also fix a pre-existing bug in Shutdown() where the timeout branch used a blocking receive on p.done instead of a non-blocking select, which prevented shutdownJobs() from ever being called on timeout.

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:
- 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 uselocalhostor127.0.0.1as instance IP; - Runner token, you can get it from
http://192.168.8.8:3000/admin/actions/runners; - Runner name, you can just leave it blank;
- 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.
