## Using Rootless Docker with`act_runner`
|
|
|
|
Here is a simple example of how to set up `act_runner` with rootless Docker. It has been created with Debian, but other Linux should work the same way.
|
|
|
|
Note: This procedure needs a real login shell -- using `sudo su` or other method of accessing the account will fail some of the steps below.
|
|
|
|
As `root`:
|
|
|
|
- Create a user to run both `docker` and `act_runner`. In this example, we use a non-privileged account called `rootless`.
|
|
|
|
```bash
|
|
useradd -m rootless
|
|
passwd rootless
|
|
apt-get install -y uidmap # Not mentioned but needed for docker rootless.
|
|
```
|
|
|
|
- Install [`docker-ce`](https://docs.docker.com/engine/install/)
|
|
- (Recommended) Disable the system-wide Docker daemon
|
|
|
|
``systemctl disable --now docker.service docker.socket``
|
|
|
|
As the `rootless` user:
|
|
|
|
- Follow the instructions for [enabling rootless mode](https://docs.docker.com/engine/security/rootless/)
|
|
- Add the following line to the `/home/rootless/.bashrc`:
|
|
|
|
```bash
|
|
for f in ./.bashrc.d/*.bash; do echo "Processing $f file..."; . "$f"; done
|
|
```
|
|
|
|
- Create the .bashrc.d directory `mkdir ~/.bashrc.d`
|
|
- Add the following lines to the `/home/rootless/.bashrc.d/rootless-docker.bash`:
|
|
|
|
```bash
|
|
export XDG_RUNTIME_DIR=/home/rootless/.docker/run
|
|
export PATH=/home/rootless/bin:$PATH
|
|
export DOCKER_HOST=unix:///run/user/$(id -u)/docker.sock
|
|
```
|
|
|
|
- Reboot. Ensure that the Docker process is working.
|
|
- Create a directory for saving `act_runner` data between restarts
|
|
|
|
`mkdir /home/rootless/act_runner`
|
|
|
|
- Register the runner from the data directory
|
|
|
|
```bash
|
|
cd /home/rootless/act_runner
|
|
act_runner register
|
|
```
|
|
|
|
- Generate a `act_runner` configuration file in the data directory. Edit the file to adjust for the system.
|
|
|
|
```bash
|
|
act_runner generate-config >/home/rootless/act_runner/config
|
|
```
|
|
|
|
- Create a new user-level`systemd` unit file as `/home/rootless/.config/systemd/user/act_runner.service` with the following contents:
|
|
|
|
```bash
|
|
Description=Gitea Actions runner
|
|
Documentation=https://gitea.com/gitea/act_runner
|
|
After=docker.service

[Install]
|
|

|
|
```
|
|
|
|
- Reboot
|
|
|
|
After the system restarts, check that the`act_runner` is working and that the runner is connected to Gitea.
|
|
|
|
````bash
|
|
systemctl --user status act_runner
|
|
journalctl --user -xeu act_runner
