docs: clarify cache reachability for dockerized runners (#1069)

Refs https://gitea.com/gitea/runner/issues/155

The remaining failure mode described in the issue comments is the job container timing out when it tries to reach ACTIONS_CACHE_URL. The generated config now explains that cache.host/cache.port must be reachable from job containers, and calls out dockerized runners with auto-created per-job networks as a case that may need a fixed published cache endpoint or a shared Docker network

+### Image flavours
+
+The image is published in three flavours, all built from the single multi-stage [Dockerfile](Dockerfile) in this repository. They differ only in how a Docker daemon is made available to the jobs the runner executes; the `gitea-runner` binary inside them is identical.
+
+| Tag | Build target | Base image | Docker daemon | Process supervisor | Runs as |
+| --- | --- | --- | --- | --- | --- |
+| `latest` (and `<version>`) | `basic` | `alpine` | none — uses an external daemon you provide | [`tini`](https://github.com/krallin/tini) | `root` |
+| `latest-dind` | `dind` | `docker:dind` | bundled, started inside the container | [`s6`](https://skarnet.org/software/s6/) | `root` (privileged) |
+| `latest-dind-rootless` | `dind-rootless` | `docker:dind-rootless` | bundled, started rootless inside the container | [`s6`](https://skarnet.org/software/s6/) | `rootless` (UID 1000) |
+
+#### `latest` — basic
+
+The default flavour ships only the runner on a minimal Alpine base. It contains **no Docker daemon of its own**: jobs that use `docker://` images need a daemon supplied from outside the container, typically by bind-mounting the host's socket:
+
+```bash
+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/runner:latest
+```
+
+`tini` is the entrypoint (it reaps zombie processes), and it just runs [`scripts/run.sh`](scripts/run.sh), which registers the runner on first start and then execs `gitea-runner daemon`. This flavour does not need `--privileged`. The trade-off is that jobs share the host's daemon, so they can see other containers and images on that daemon.
+
+#### `latest-dind` — Docker-in-Docker
+
+This flavour is based on the official `docker:dind` image and bundles its own Docker daemon, so it needs no external socket — only the `--privileged` flag that Docker-in-Docker requires:
+
+```bash
+docker run --privileged -e GITEA_INSTANCE_URL=https://your_gitea.com -e GITEA_RUNNER_REGISTRATION_TOKEN=<your_token> \
+  --name my_runner gitea/runner:latest-dind
+```
+
+Two processes have to run side by side here (the Docker daemon and the runner), so the entrypoint is the [`s6`](https://skarnet.org/software/s6/) supervision tree under [`scripts/s6`](scripts/s6) instead of `tini`. `s6` starts `dockerd`, and the runner service waits for the daemon to come up (`s6-svwait`) before launching [`run.sh`](scripts/run.sh). Each container has a private daemon isolated from the host's, at the cost of running privileged.
+
+#### `latest-dind-rootless` — rootless Docker-in-Docker
+
+Same idea as `dind`, but built on `docker:dind-rootless` so the bundled daemon and the runner run as an unprivileged user (`rootless`, UID 1000) rather than `root`. `DOCKER_HOST` is preset to `unix:///run/user/1000/docker.sock` so the runner talks to the rootless daemon. This reduces the blast radius compared to the privileged `dind` flavour, but rootless Docker carries the usual rootless limitations (networking, cgroups, storage drivers, and some operations that need additional host configuration such as `/etc/subuid` / `/etc/subgid` mappings and unprivileged user-namespace support).
+
+> **Note on Podman:** these images target the Docker daemon. The bundled `dind`/`dind-rootless` daemons are `dockerd`, not Podman, and the `basic` flavour expects a Docker-compatible socket. Running them under rootless Podman is not a supported configuration, though pointing the `basic` flavour at a Podman socket that emulates the Docker API may work for some workloads.

 ### Configuration
 
 The runner is configured with a YAML file. Generate a starting point (this matches what ships in the tree):

-#### External cache (`actions/cache`)
+#### Caching (`actions/cache`)
 
-If `cache.external_server` is set, you must set `cache.external_secret` to the same value on this runner and on the standalone cache server. Run the server with `gitea-runner cache-server` using a config that defines `cache.external_secret` (and matching `cache.dir` / host / port as needed). Flags `--dir`, `--host`, and `--port` on `cache-server` override the file.
+Each runner starts its own cache server automatically. Cache entries are local to that runner — runners do not share a cache by default.
+
+**Shared cache across multiple runners**
+
+Run one dedicated `gitea-runner cache-server` that all runners point at.
+
+1. Create a config file for the cache server host:
+
+   ```yaml
+   cache:
+     dir: /data/actcache
+     port: 8088
+     external_secret: "replace-with-a-strong-random-secret"
+   ```
+
+2. Start the server:
+
+   ```bash
+   gitea-runner -c cache-server-config.yaml cache-server
+   ```
+
+3. On every runner:
+
+   ```yaml
+   cache:
+     external_server: "http://<cache-server-host>:8088/"
+     external_secret: "replace-with-a-strong-random-secret"  # must match the server
+   ```
+
+Alternatively, mount the same NFS/CIFS share on every runner and point `cache.dir` at it — simpler, but with weaker isolation between repositories.
+
+**S3 / MinIO** — mount object storage as a FUSE filesystem (e.g. [s3fs](https://github.com/s3fs-fuse/s3fs-fuse) or [goofys](https://github.com/kahing/goofys)) and set `cache.dir` to the mount point.
+
+Flags `--dir`, `--host`, and `--port` on `cache-server` override the corresponding `cache.*` YAML keys; all other settings, including `external_secret`, require the config file.

+#### Post-task script (`runner.post_task_script`)
+
+Optional host script that runs **after** each task's built-in cleanup (post-steps, container teardown, bind-workdir removal). Use it for extra machine housekeeping — Docker pruning, disk cleanup, and similar.
+
+**While the script runs, the runner stops task heartbeats and stays offline from Gitea's perspective until the script exits (or hits `runner.post_task_script_timeout`, default `5m`).** A script that blocks without exiting keeps the runner from taking new work for up to that timeout. Script output goes to the runner log, not the job log; a non-zero exit is warned but does not change the job result.
+
+On Windows, use `.exe`, `.bat`, or `.cmd` paths; **PowerShell (`.ps1`) is not supported yet** as the configured path — wrap commands in a `.cmd` file instead.

+# Post-task script
+
+The post-task script is an optional host hook that runs **once after every task**, after the runner has already finished its normal per-task cleanup. Typical uses include pruning Docker images, vacuuming ephemeral disks, or resetting VM state between jobs.
+
+It is configured under `runner.post_task_script` in the runner YAML config (see [config.example.yaml](../internal/pkg/config/config.example.yaml)).
+
+## When it runs
+
+For each task, execution order is:
+
+1. Workflow runs (steps, actions, containers).
+2. In-job cleanup (action `post:` steps, container stop/remove).
+3. Job outputs are reported to Gitea.
+4. Bind-workdir workspace removal, when `container.bind_workdir` is enabled.
+5. **Post-task script** (this hook).
+6. Final task acknowledgement to Gitea (`reporter.Close()`).
+
+The script is **additive**: it does not replace any built-in cleanup. When `container.bind_workdir` is enabled, the task workspace directory has usually already been deleted before the script starts. `GITEA_WORKSPACE` is still set to the path the job used, for reference.
+
+## Runner stays offline until the script finishes
+
+This is the most important operational detail.
+
+When the post-task script starts, the runner **stops sending task heartbeats** to Gitea (the same mechanism used during cancel/cleanup). From Gitea's perspective, the runner is **not available for new work** until:
+
+1. The script exits (success or failure), **and**
+2. The runner sends the final task flush to Gitea.
+
+While the script runs:
+
+- **Gitea will not assign another task** to this runner for the current job slot (heartbeats are stopped).
+- **The runner capacity slot stays occupied** locally — with `capacity: 1`, the poller will not start another task until the script completes.
+- **Runner shutdown** (`shutdown_timeout`) counts this phase as part of the in-flight task; a long or stuck script delays graceful shutdown.
+
+If the script **never exits**, the runner remains in this state until `runner.post_task_script_timeout` elapses (default **5 minutes** when a script is configured). The runner then kills the script process and proceeds to the final acknowledgement. Until that timeout fires, **the runner effectively stays offline**.
+
+Set `post_task_script_timeout` to a value that matches how long your housekeeping is allowed to take — not how long you wish it could take. Prefer short, bounded scripts.
+
+### Recommendations
+
+- Keep scripts **fast and bounded** (seconds, not minutes).
+- Avoid interactive prompts, blocking network calls without timeouts, or waiting on user input.
+- Use **idempotent** operations (the script may run after success, failure, or cancellation).
+- Test failure modes: hung script, non-zero exit, missing executable.
+- Watch the **runner process log** for script output (it is not written to the Gitea job log).
+- On shutdown, ensure scripts respond to process termination within `post_task_script_timeout`.
+
+## Configuration
+
+```yaml
+runner:
+  # Path to an executable on the host. Empty or omitted disables the hook.
+  post_task_script: /usr/local/bin/gitea-post-task.sh
+
+  # Hard limit on script runtime. Default when post_task_script is set: 5m.
+  # If the script exceeds this, it is killed and the runner continues.
+  post_task_script_timeout: 2m
+```
+
+| Option | Default | Description |
+| --- | --- | --- |
+| `runner.post_task_script` | *(disabled)* | Host path to the script or binary. Relative paths are resolved from the runner process working directory. |
+| `runner.post_task_script_timeout` | `5m` (only when script is set) | Maximum time the script may run before the runner kills it and moves on. |
+
+The script must be **executable** on the host (shebang on Linux/macOS, or a native `.exe` / `.bat` / `.cmd` on Windows). **PowerShell (`.ps1`) is not supported yet** as the value of `post_task_script`; the runner executes the configured path directly and does not invoke `powershell.exe` for you.
+
+`gitea-runner exec` does **not** load runner YAML and will not run this hook.
+
+## Environment variables
+
+The script receives `runner.envs` / `runner.env_file` values plus:
+
+| Variable | Description |
+| --- | --- |
+| `GITEA_TASK_ID` | Numeric task ID. |
+| `GITEA_RUN_ID` | Workflow run ID, when provided by the server. |
+| `GITEA_REPOSITORY` | Repository slug (`owner/name`). |
+| `GITEA_WORKSPACE` | Workspace path used for the job (may already be deleted). |
+| `GITEA_JOB_RESULT` | `success`, `failure`, `cancelled`, `skipped`, or `unknown`. |
+
+The script environment is **not** a full copy of the job container environment. System variables such as `PATH` are only present if you define them in `runner.envs` or `runner.env_file`.
+
+## Output and errors
+
+- **Stdout/stderr** are written to the **runner process log** (logrus), prefixed with `post-task script stdout:` / `post-task script stderr:`.
+- **Non-zero exit codes** are logged as warnings only. They do **not** change the job result already reported to Gitea.
+- **Timeouts and start failures** are logged as warnings; the runner still completes the task acknowledgement.
+
+## Interaction with other timeouts
+
+| Timeout | Effect on post-task script |
+| --- | --- |
+| `runner.post_task_script_timeout` | Kills the script if it runs too long. This is the **only** timeout that bounds the script. |
+| `runner.timeout` | Caps the task **up to** the script. The script detaches from the task deadline, so a job near the runner timeout limit does **not** cut the script short — it still gets its full `post_task_script_timeout`. |
+| `runner.shutdown_timeout` | On SIGINT/SIGTERM, bounds how long the runner waits for the **task** to finish. The post-task script detaches from cancellation, so it is **not** interrupted by this window and may extend shutdown until its own `post_task_script_timeout` elapses. |

+  post_task_script: /usr/local/bin/gitea-post-task.sh
+  post_task_script_timeout: 3m
+```
+
+### Windows — batch file (`.cmd`)
+
+Use a `.cmd` or `.bat` file. PowerShell scripts are **not supported yet** as `post_task_script`; call PowerShell from a batch wrapper if needed:
+
+`C:\gitea-runner\scripts\post-task.cmd`:
+
+```bat
+@echo off
+docker image prune -f
+```
+
+```yaml
+runner:
+  post_task_script: C:\gitea-runner\scripts\post-task.cmd
+  post_task_script_timeout: 3m
+```
+
+PowerShell workaround until native `.ps1` support exists:
+
+`C:\gitea-runner\scripts\post-task.cmd`:
+
+```bat
+@echo off
+powershell.exe -NoProfile -NonInteractive -ExecutionPolicy Bypass -File "%~dp0post-task.ps1"
+```
+
+## Windows notes
+
+- Supported as `post_task_script`: `.exe`, `.bat`, `.cmd`.
+- **Not supported yet:** `.ps1` as the configured path (use a `.cmd` wrapper; see above).
+- `.sh` files require a Unix shell on the PATH unless you point `post_task_script` at the interpreter.
+- Use backslashes or forward slashes in YAML paths; both work in Go on Windows.
+
+## See also

+- [Configuration](../README.md#configuration) — generating and loading `config.yaml`
+- [config.example.yaml](../internal/pkg/config/config.example.yaml) — all runner options
+- Bind-workdir idle cleanup (`runner.workdir_cleanup_age`) — separate from this hook; runs only when the runner is idle
