If no `Forgejo runner` is available, `Forgejo` will wait for one to connect and submit the job as soon as it is available.
### Labels and `runs-on`
## Labels and `runs-on`
The workflows / tasks defined in the files found in `.forgejo/workflows` must specify the environment they need to run with `runs-on`. Each `Forgejo runner` declares, when they connect to the `Forgejo` instance the list of labels they support so `Forgejo` sends them tasks accordingly. For instance if a job within a workflow has:

If the list of labels is empty, it defaults to `docker:docker://node:16-bullseye` and will declare the label `docker`.
- **Docker or Podman:**
If `runs-on` is matched to a label mapped to `docker://`, the rest of it is interpreted as the default container image to use if no other is specified. The runner will execute all the steps, as root, within a container created from that image. The default container image can be overridden by a workflow to use `alpine:3.18` as follows.

- **LXC:**
If `runs-on` is matched to a label mapped to `lxc://`, the rest of it is interpreted as the default [template and release](https://images.linuxcontainers.org/) to use if no other is specified. The runner will execute all the steps, as root, within a [LXC container](https://linuxcontainers.org/) created from that template and release. The default template is `debian` and the default release is `bullseye`. They can be overridden by a workflow to use `debian` and `bookworm` as follows.
Labels examples:
```yaml
runs-on: lxc
container:
- `node20:docker://node:20-bookworm` == `node20:docker://docker.io/node:20-bookworm` defines `node20` to be the `node:20-bookworm` image from hub.docker.com
- `docker:docker://code.forgejo.org/oci/alpine:3.18` defines `docker` to be the `alpine:3.18` image from https://code.forgejo.org/oci/-/packages/container/alpine/3.18

- **self-hosted:**
If `runs-on` is matched to a label mapped to `host://-self-hosted``, the runner will execute all the steps in a shell forked from the runner, directly on the host.
Labels examples:
- `bookworm:lxc://debian:bookworm` defines bookworm to be an LXC container running Debian GNU/Linux bookworm.
### shell
If `runs-on` is matched to a label mapped to `host://-self-hosted``, the runner will execute all the steps in a shell forked from the runner, directly on the host.
Label example:
- `self-hosted:host://-self-hosted` defines `self-hosted` to be a shell
