-# act runner
+# Forgejo Runner
 
-Act runner is a runner for Gitea based on [act](https://gitea.com/gitea/act).
+**WARNING:** this is [alpha release quality](https://en.wikipedia.org/wiki/Software_release_life_cycle#Alpha) code and should not be considered secure enough to deploy in production.
 
-## Prerequisites
+A daemon that connects to a Forgejo instance and runs jobs for continous integration. The [installation and usage instructions](https://forgejo.org/docs/next/admin/actions/) are part of the Forgejo documentation.
 
-Docker Engine Community version is required. To install Docker CE, follow the official [install instructions](https://docs.docker.com/engine/install/).
+# Reporting bugs
 
-## Quickstart
+When filing a bug in [the issue tracker](https://code.forgejo.org/forgejo/runner/issues), it is very helpful to propose a pull request [in the end-to-end tests](https://code.forgejo.org/forgejo/end-to-end/src/branch/main/actions) repository that adds a reproducer. It will fail the CI and unambiguously demonstrate that the problem exists. In most cases it is enough to add a workflow ([see the echo example](https://code.forgejo.org/forgejo/end-to-end/src/branch/main/actions/example-echo)). For more complicated cases it is also possible to add a runner config file as well as shell scripts to setup and teardown the test case ([see the service example](https://code.forgejo.org/forgejo/end-to-end/src/branch/main/actions/example-service)).
 
-### Build
+# Hacking
 
-```bash
+The Forgejo runner depends on [a fork of ACT](https://code.forgejo.org/forgejo/act) and is a dependency of the [setup-forgejo action](https://code.forgejo.org/actions/setup-forgejo). See [the full dependency graph](https://code.forgejo.org/actions/cascading-pr/#forgejo-dependencies) for a global view.
-make build
+
+## Local debug
+
+The repositories are checked out in the same directory:
+
+- **runner**: [Forgejo runner](https://code.forgejo.org/forgejo/runner)
+- **act**: [ACT](https://code.forgejo.org/forgejo/act)
+- **setup-forgejo**: [setup-forgejo](https://code.forgejo.org/actions/setup-forgejo)
+
+### Install dependencies
+
+The dependencies are installed manually or with:
+
+```shell
+setup-forgejo/forgejo-dependencies.sh
 ```
 
-### Register
+### Build the Forgejo runner with the local ACT
 
-```bash
+The Forgejo runner is rebuilt with the ACT directory by changing the `runner/go.mod` file to:
-./act_runner register
+
+```
+replace github.com/nektos/act => ../act
 ```
 
-And you will be asked to input:
+Running:
 
-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;
+cd runner ; go mod tidy
-2. Runner token, you can get it from `http://192.168.8.8:3000/admin/runners`;
-3. Runner name, you can just leave it blank;
-4. Runner labels, you can just leave it blank.
-
-The process looks like:
-
-```text
-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, self-hosted,ubuntu-20.04:docker://node:16-bullseye,ubuntu-18.04:docker://node:16-buster):
-
-INFO Registering runner, name=Test.local, instance=http://192.168.8.8:3000/, labels=[ubuntu-latest:docker://node:16-bullseye ubuntu-22.04:docker://node:16-bullseye ubuntu-20.04:docker://node:16-bullseye ubuntu-18.04:docker://node:16-buster].
-DEBU Successfully pinged the Gitea instance server
-INFO Runner registered successfully.
 ```
 
-You can also register with command line arguments.
+Building:
 
-```bash
+```shell
-./act_runner register --instance http://192.168.8.8:3000 --token <my_runner_token> --no-interactive
+cd runner ; rm -f forgejo-runner ; make forgejo-runner
 ```
 
-If the registry succeed, it will run immediately. Next time, you could run the runner directly.
+### Launch Forgejo and the runner
 
-### Run
+A Forgejo instance is launched with:
 
-```bash
+```shell
-./act_runner daemon
+cd setup-forgejo
+./forgejo.sh setup
+firefox $(cat forgejo-url)
+```
+
+The user is `root` with password `admin1234`. The runner is registered with:
+
+```
+cd setup-forgejo
+docker exec --user 1000 forgejo forgejo actions generate-runner-token > forgejo-runner-token
+../runner/forgejo-runner register --no-interactive --instance "$(cat forgejo-url)" --name runner --token $(cat forgejo-runner-token) --labels docker:docker://node:20-bullseye,self-hosted:host://-self-hosted,lxc:lxc://debian:bullseye
+```
+
+And launched with:
+
+```shell
+cd setup-forgejo ; ../runner/forgejo-runner --config runner-config.yml daemon
+```
+
+Note that the `runner-config.yml` is required in that particular case
+to configure the network in `bridge` mode, otherwise the runner will
+create a network that cannot reach the forgejo instance.
+
+### Try a sample workflow
+
+From the Forgejo web interface, create a repository and add the
+following to `.forgejo/workflows/try.yaml`. It will launch the job and
+the result can be observed from the `actions` tab.
+
+```yaml
+on: [push]
+jobs:
+  ls:
+    runs-on: docker
+    steps:
+      - uses: actions/checkout@v3
+      - run: |
+          ls ${{ github.workspace }}
 ```

+# Release Notes
+
+## 3.5.2
+
+* Fix [crash in some cases when the YAML structure is not as expected](https://code.forgejo.org/forgejo/runner/issues/267).
+
+## 3.5.1
+
+* Fix [CVE-2024-24557](https://nvd.nist.gov/vuln/detail/CVE-2024-24557)
+* [Add report_interval option to config](https://code.forgejo.org/forgejo/runner/pulls/220) to allow setting the interval of status and log reports
+
+## 3.5.0
+
+* [Allow graceful shutdowns](https://code.forgejo.org/forgejo/runner/pulls/202): when receiving a signal (INT or TERM) wait for running jobs to complete (up to shutdown_timeout).
+* [Fix label declaration](https://code.forgejo.org/forgejo/runner/pulls/176): Runner in daemon mode now takes labels found in config.yml into account when declaration was successful.
+* [Fix the docker compose example](https://code.forgejo.org/forgejo/runner/pulls/175) to workaround the race on labels.
+* [Fix the kubernetes dind example](https://code.forgejo.org/forgejo/runner/pulls/169).
+* [Rewrite ::group:: and ::endgroup:: commands like github](https://code.forgejo.org/forgejo/runner/pulls/183).
+* [Added opencontainers labels to the image](https://code.forgejo.org/forgejo/runner/pulls/195)
+* [Upgrade the default container to node:20](https://code.forgejo.org/forgejo/runner/pulls/203)
+
+## 3.4.1
+
+* Fixes a regression introduced in 3.4.0 by which a job with no image explicitly set would
+  [be bound to the host](https://code.forgejo.org/forgejo/runner/issues/165)
+  network instead of a custom network (empty string in the configuration file).
+
+## 3.4.0
+
+Although this version is able to run [actions/upload-artifact@v4](https://code.forgejo.org/actions/upload-artifact/src/tag/v4) and [actions/download-artifact@v4](https://code.forgejo.org/actions/download-artifact/src/tag/v4), these actions will fail because it does not run against GitHub.com. A fork of those two actions with this check disabled is made available at:
+
+* https://code.forgejo.org/forgejo/upload-artifact/src/tag/v4
+* https://code.forgejo.org/forgejo/download-artifact/src/tag/v4
+
+and they can be used as shown in [an example from the end-to-end test suite](https://code.forgejo.org/forgejo/end-to-end/src/branch/main/actions/example-artifacts-v4/.forgejo/workflows/test.yml).
+
+* When running against codeberg.org, the default poll frequency is 30s instead of 2s.
+* Fix compatibility issue with actions/{upload,download}-artifact@v4.
+* Upgrade ACT v1.20.0 which brings:
+  * `[container].options` from the config file is exposed in containers created by the workflows
+  * the expressions in the value of `jobs.<job-id>.runs-on` are evaluated
+  * fix a bug causing the evaluated expression of `jobs.<job-id>.runs-on` to fail if it was an array
+  * mount `act-toolcache:/opt/hostedtoolcache` instead of `act-toolcache:/toolcache`
+  * a few improvements to the readability of the error messages displayed in the logs
+  * `amd64` can be used instead of `x86_64` and `arm64` intead of `aarch64` when specifying the architecture
+  * fixed YAML parsing bugs preventing dispatch workflows to be parsed correctly
+  * add support for `runs-on.labels` which is equivalent to `runs-on` followed by a list of labels
+  * the expressions in the service `ports` and `volumes` values are evaluated
+  * network aliases are only supported when the network is user specified, not when it is provided by the runner
+* If `[runner].insecure` is true in the configuration, insecure cloning actions is allowed
+
+## 3.3.0
+
+* Support IPv6 with addresses from a private range and NAT for
+    docker:// with --enable-ipv6 and [container].enable_ipv6
+    lxc:// always
+
+## 3.2.0
+
+* Support LXC container capabilities via `lxc:lxc://debian:bookworm:k8s` or  `lxc:lxc://debian:bookworm:docker lxc k8s`
+* Update ACT v1.16.0 to resolve a [race condition when bootstraping LXC templates](https://code.forgejo.org/forgejo/act/pulls/23)
+
+## 3.1.0
+
+The `self-hosted` label that was hardwired to be a LXC container
+running `debian:bullseye` was reworked and documented ([user guide](https://forgejo.org/docs/next/user/actions/#jobsjob_idruns-on) and [admin guide](https://forgejo.org/docs/next/admin/actions/#labels-and-runs-on)).
+
+There now are two different schemes: `lxc://` for LXC containers and
+`host://` for running directly on the host.
+
+* Support the `host://` scheme for running directly on the host.
+* Support the `lxc://` scheme in labels
+* Update [code.forgejo.org/forgejo/act v1.14.0](https://code.forgejo.org/forgejo/act/pulls/19) to implement both self-hosted and LXC schemes
+
+## 3.0.3
+
+* Update [code.forgejo.org/forgejo/act v1.13.0](https://code.forgejo.org/forgejo/runner/pulls/106) to keep up with github.com/nektos/act
+
+## 3.0.2
+
+* Update [code.forgejo.org/forgejo/act v1.12.0](https://code.forgejo.org/forgejo/runner/pulls/106) to upgrade the node installed in the LXC container to node20
+
+## 3.0.1
+
+* Update [code.forgejo.org/forgejo/act v1.11.0](https://code.forgejo.org/forgejo/runner/pulls/86) to resolve a bug preventing actions based on node20 from running, such as [checkout@v4](https://code.forgejo.org/actions/checkout/src/tag/v4).
+
+## 3.0.0
+
+* Publish a rootless OCI image
+* Refactor the release process
+
+## 2.5.0
+
+* Update [code.forgejo.org/forgejo/act v1.10.0](https://code.forgejo.org/forgejo/runner/pulls/71)

+* Update [code.forgejo.org/forgejo/act v1.9.0](https://code.forgejo.org/forgejo/runner/pulls/64)
+

+## Docker compose with docker-in-docker
+
+The `compose-forgejo-and-runner.yml` compose file runs a Forgejo
+instance and registers a `Forgejo runner`. A docker server is also
+launched within a container (using
+[dind](https://hub.docker.com/_/docker/tags?name=dind)) and will be
+used by the `Forgejo runner` to execute the workflows.
+
+### Quick start
+
+```sh
+rm -fr /srv/runner-data /srv/forgejo-data
+secret=$(openssl rand -hex 20)
+sed -i -e "s/{SHARED_SECRET}/$secret/" compose-forgejo-and-runner.yml
+docker compose -f compose-forgejo-and-runner.yml up -d
+```
+
+Visit http://0.0.0.0:8080/admin/actions/runners with login `root` and password `{ROOT_PASSWORD}` and see the runner is registered with the label `docker`.
+
+> NOTE: the `Your ROOT_URL in app.ini is "http://localhost:3000/", it's unlikely matching the site you are visiting.` message is a warning that can be ignored in the context of this example.
+
+```sh
+docker compose -f compose-forgejo-and-runner.yml -f compose-demo-workflow.yml up demo-workflow
+```
+
+Visit http://0.0.0.0:8080/root/test/actions/runs/1 and see that the job ran.
+
+
+### Running
+
+Create a shared secret with:
+
+```sh
+openssl rand -hex 20
+```
+
+Replace all occurences of {SHARED_SECRET} in
+[compose-forgejo-and-runner.yml](compose-forgejo-and-runner.yml).
+
+> **NOTE:** a token obtained from the Forgejo web interface cannot be used as a shared secret.
+
+Replace {ROOT_PASSWORD} with a secure password in
+[compose-forgejo-and-runner.yml](compose-forgejo-and-runner.yml).
+
+```sh
+docker compose -f compose-forgejo-and-runner.yml up
+Creating docker-compose_docker-in-docker_1 ... done
+Creating docker-compose_forgejo_1          ... done
+Creating docker-compose_runner-register_1  ... done

+```
+
+### Manual testing
+
+To login the Forgejo instance:
+
+* URL: http://0.0.0.0:8080
+* user: `root`
+* password: `{ROOT_PASSWORD}`
+
+`Forgejo Actions` is enabled by default when creating a repository.
+
+## Tests workflow
+
+The `compose-demo-workflow.yml` compose file runs two demo workflows:
+* one to verify the `Forgejo runner` can pick up a task from the Forgejo instance
+and run it to completion.
+* one to verify docker can be run inside the `Forgejo runner` container.
+
+A new repository is created in root/test with the following workflows:
+
+#### `.forgejo/workflows/demo.yml`:
+
+```yaml
+on: [push]
+jobs:
+  test:
+    runs-on: docker
+    steps:
+      - run: echo All Good
+```
+
+#### `.forgejo/workflows/demo_docker.yml`
+
+```yaml
+on: [push]
+jobs:
+  test_docker:
+    runs-on: ubuntu-22.04
+    steps:
+      - run: docker info
+```
+
+A wait loop expects the status of the check associated with the
+commit in Forgejo to show "success" to assert the workflow was run.
+
+### Running
+
+```sh
+$ docker-compose -f compose-forgejo-and-runner.yml -f compose-demo-workflow.yml up demo-workflow
+...
+demo-workflow_1     | To http://forgejo:3000/root/test
+demo-workflow_1     |  + 5ce134e...261cc79 main -> main (forced update)
+demo-workflow_1     | branch 'main' set up to track 'http://root:admin1234@forgejo:3000/root/test/main'.
+...
+demo-workflow_1     | running
+...
+```

+## Kubernetes Docker in Docker Deployment
+
+Registers Kubernetes pod runners using [offline registration](https://forgejo.org/docs/v1.21/admin/actions/#offline-registration), allowing the scaling of runners as needed.
+
+NOTE: Docker in Docker (dind) requires elevated privileges on Kubernetes. The current way to achieve this is to set the pod `SecurityContext` to `privileged`. Keep in mind that this is a potential security issue that has the potential for a malicious application to break out of the container context.
+
+[`dind-docker.yaml`](dind-docker.yaml) creates a deployment and secret for Kubernetes to act as a runner. The Docker credentials are re-generated each time the pod connects and does not need to be persisted.

+# Forgejo Runner with systemd User Services
+
+It is possible to use systemd's user services together with 
+[podman](https://podman.io/) to run `forgejo-runner` using a normal user 
+account without any privileges and automatically start on boot.
+
+This was last tested on Fedora 39 on 2024-02-19, but should work elsewhere as 
+well.
+
+Place the `forgejo-runner` binary in `/usr/local/bin/forgejo-runner` and make
+sure it can be executed (`chmod +x /usr/local/bin/forgejo-runner`).
+
+Install and enable `podman` as a user service:
+
+```bash
+$ sudo dnf -y install podman
+```
+
+You *may* need to reboot your system after installing `podman` as it 
+modifies some system configuration(s) that may need to be activated. Without
+rebooting the system my runner errored out when trying to set firewall rules, a
+reboot fixed it.
+
+Enable `podman` as a user service:
+
+```
+$ systemctl --user start podman.socket
+$ systemctl --user enable podman.socket
+```
+
+Make sure processes remain after your user account logs out:
+
+```bash
+$ loginctl enable-linger
+```
+
+Create the file `/etc/systemd/user/forgejo-runner.service` with the following
+content:
+
+```
+[Unit]
+Description=Forgejo Runner
+
+[Service]
+Type=simple
+ExecStart=/usr/local/bin/forgejo-runner daemon
+Restart=on-failure
+
+[Install]
+WantedBy=default.target
+```
+
+Now activate it as a user service:
+
+```bash
+$ systemctl --user daemon-reload
+$ systemctl --user start forgejo-runner
+$ systemctl --user enable forgejo-runner
+```
+
+To see/follow the log of `forgejo-runner`:
+
+```bash
+$ journalctl -f -t forgejo-runner
+```
+
+If you reboot your system, all should come back automatically.
