## Codeberg
|
|
|
|
Codeberg provides a LXC container with 48GB RAM, 24 threads and SSD drive to be used for the CI. A Forgejo Runner is installed in `/opt/runner` and registered with a token obtained from https://codeberg.org/forgejo. It does not allow running privileged containers or LXC containers for security reasons. The runner is intended to be used for pull requests, for instance in https://codeberg.org/forgejo/forgejo.
|
|
|
|
## Octopuce
|
|
|
|
[Octopuce provides hardware](https://codeberg.org/forgejo/sustainability) managed by [the devops team](https://codeberg.org/forgejo/governance/src/branch/main/TEAMS.md#devops). It can be accessed via a VPN which provides a DNS for the `octopuce.forgejo.org` internal domain.
|
|
|
|
The VPN is deployed and upgraded using the following [Enough command line](https://enough-community.readthedocs.io):
|
|
|
|
```shell
|
|
$ mkdir -p ~/.enough
|
|
$ git clone https://forgejo.octopuce.forgejo.org/forgejo/enough-octopuce ~/.enough/octopuce.forgejo.org
|
|
$ enough --domain octopuce.forgejo.org service create openvpn
|
|
```
|
|
|
|
## Hetzner
|
|
|
|
https://hetzner01.forgejo.org runs on an [EX101](https://www.hetzner.com/dedicated-rootserver/ex101) Hetzner hardware.
|
|
|
|
## OVH
|
|
|
|
https://code.forgejo.org runs on an OVH virtual machine using the same
|
|
OVH account used for the forgejo.org domain name and mails.
|
|
|
|
It is deployed and upgraded using the following [Enough command line](https://enough-community.readthedocs.io):
|
|
|
|
```shell
|
|
$ mkdir -p ~/.enough
|
|
$ git clone https://forgejo.octopuce.forgejo.org/forgejo/enough-code ~/.enough/code.forgejo.org
|
|
$ enough --domain code.forgejo.org service create --host bind-host forgejo
|
|
```
|
|
|
|
Upgrading only Forgejo:
|
|
|
|
```shell
|
|
$ enough --domain code.forgejo.org playbook -- --limit bind-host,localhost --private-key ~/.enough/code.forgejo.org/infrastructure_key venv/share/enough/playbooks/forgejo/forgejo-playbook.yml
|
|
```
|
|
|
|
Login in the machine hosting the Forgejo instance for debugging purposes:
|
|
|
|
```shell
|
|
enough --domain code.forgejo.org ssh bind-host
|
|
```
|
|
|
|
## Installing Forgejo runners
|
|
|
|
### Preparing the LXC hypervisor
|
|
|
|
```shell
|
|
git clone https://code.forgejo.org/forgejo/lxc-helpers/
|
|
|
|
lxc-helpers.sh lxc_prepare_environment
|
|
sudo lxc-helpers.sh lxc_install_lxc_inside 10.120.13
|
|
```
|
|
|
|
### Creating an LXC container
|
|
|
|
```shell
|
|
lxc-helpers.sh lxc_container_create forgejo-runners
|
|
lxc-helpers.sh lxc_container_start forgejo-runners
|
|
lxc-helpers.sh lxc_container_user_install forgejo-runners $(id -u) $USER
|
|
lxc-helpers.sh lxc_container_run forgejo-runners -- sudo --user debian bash
|
|
sudo apt-get update
|
|
sudo apt-get install -y wget docker.io emacs-nox
|
|
sudo usermod -aG docker $USER # exit & enter again for the group to be active
|
|
lxc-helpers.sh lxc_prepare_environment
|
|
sudo wget -O /usr/local/bin/forgejo-runner https://code.forgejo.org/forgejo/runner/releases/download/v2.0.4/forgejo-runner-amd64
|
|
sudo chmod +x /usr/local/bin/forgejo-runner
|
|
echo 'export TERM=vt100' >> .bashrc
|
|
```
|
|
|
|
### Creating a runner
|
|
|
|
Multiple runners can co-exist on the same machine. To keep things
|
|
organized they are located in a directtory that is the same as the url
|
|
from which the token is obtained. For instance
|
|
DIR=codeberg.org/forgejo-integration means that the token was obtained from the
|
|
https://codeberg.org/forgejo-integration organization.
|
|
|
|
If a runner only provides unprivileged docker containers, the labels
|
|
should be
|
|
`LABELS=docker:docker://node:16-bullseye,ubuntu-latest:docker://node:16-bullseye`.
|
|
|
|
If a runner provides LXC containers and unprivileged docker
|
|
containers, the labels should be
|
|
`LABELS=docker:docker://node:16-bullseye,self-hosted`.
|
|
|
|
```shell
|
|
mkdir -p $DIR ; cd $DIR
|
|
forgejo-runner generate-config > config.yml
|
|
## edit config.yml
|
|
## Obtain a $TOKEN from https://$DIR
|
|
forgejo-runner register --no-interactive --token $TOKEN --name runner --instance https://codeberg.org --labels $LABELS
|
|
forgejo-runner --config config.yml daemon |& cat -v > runner.log &
|
|
```
|
|
|
|
#### codeberg.org config.yml
|
|
|
|
- `fetch_timeout: 30s` # because it can be slow at times
|
|
- `fetch_interval: 60s` # because there is throttling and 429 replies will mess up the runner
|
|
- cache `enabled: false` # because codeberg.org is still v1.19
|
