2e72cf902a enhance(kubernetes): fetch job pod copies from the runner over the pod network (#1354)
The Kubernetes backend copies actions and workspaces into job containers with `tar` over `pods/exec`, so every byte goes through the API server. On managed clusters that often sits in other zones than the nodes, so each byte can cross zones twice, and the copies load the API server.

With `kubernetes.transfer.mode: auto` or `direct`, an init container copies `gitea-runner` into the job pod, and the job container fetches directories and copies of 64 KiB or more gzipped from the runner over the pod network. `auto` falls back to the API server for a job pod that cannot reach the runner, `direct` fails the job.

Copies can hold secrets, so each is served once, over TLS 1.3 pinned to a certificate the runner generates, only to the job pod's IPs.

Copying setup-go@v5, cache@v4, setup-java@v4 and build-push-action@v6 sends 11.6 MB through the API server on main and 532 B with this PR.

KenanZhuandsilverwind ca8e9c3c64 enhance: add GITEA_* aliases for built-in workflow environment variables (#1358)
Closes https://gitea.com/gitea/runner/issues/1317, which makes https://github.com/go-gitea/gitea/issues/39813 redundant as the runner sets these variables.

Every built-in `GITHUB_*` environment variable the runner sets is now also available as `GITEA_*` with the same value, so Gitea-native workflows don't have to rely on GitHub naming. The `GITEA_*` names mirror the `GITHUB_*` ones after their last write, so they stay equal and are unset together.

Workflow, job and runner `envs` values for these `GITEA_*` names are now overwritten, the same as for `GITHUB_*`.

3dbed63f55 fix: close the action header group before the action runs (#1345)
`uses:` steps and job hooks kept their "Run …" group open until they finished. Gitea doesn't nest groups, so the action's own first `::group::` closed the header and everything before it stayed hidden there, e.g. all of goreleaser's output in https://gitea.com/gitea/cli/actions/runs/1121069/jobs/1519275. The header group now closes right after its details, as in actions/runner.

The action header also matches actions/runner's otherwise now: it is titled by the `uses:` reference, lists the resolved inputs including `action.yml` defaults without empty ones, is shown for pre stages too, and post stages start with `Post job cleanup.`.

silverwind fe2a66dc25 fix: align runner behaviours (#1338)
Contains a number of small bug fixes where jobs behaved differently from GitHub or failed silently.

1. Hooks fail on a refused `::set-env::` or `::add-path::` and no longer inherit the last step's identity
1. Docker build, exec and wait errors are returned instead of swallowed, token-only registry credentials work, logs of `--tty` services decode
1. Env files split lines like GitHub on each OS, so a carriage return is kept on Linux and CRLF ends a line on Windows, empty heredoc names or delimiters are rejected
1. Post steps run after their pre step even when main was skipped, composites see undeclared inputs, `runs.args` wins without `with.args` being parsed
1. Docker actions skip evaluating defaults of inputs given in `with` and read `entryPoint` and `args` in any case, a lowercase `dockerfile` is found, undeclared inputs get GitHub's warning
1. A user-set `CI` is kept, `GITHUB_REPOSITORY_ID` and the other missing `GITHUB_*` variables are exported
1. `timeout-minutes` can read the step's own `env`, a step-level `ACTIONS_ALLOW_UNSECURE_COMMANDS: false` beats a job-level `true` while the runner's own opt-in still wins, `pwsh` quotes the script path
1. A step `env:` given as one expression such as `${{ fromJSON(matrix.env) }}` is applied, `hashFiles` fails with GitHub's messages on script errors and after 120 seconds, a job image without node still gets an empty hash
1. A step whose command files cannot be reset fails instead of importing stale ones, a timeout between steps fails the job instead of reporting success
1. One named volume can be mounted at several paths, host-mode PTY steps keep their last output when they fail, host scratch directories are removed when job setup fails
1. Cancelling a step right after it starts kills its whole process tree
1. Cache prefix restores pick the newest entry created within the same second, also on S3, cache commits with a wrong size are rejected
1. Artifact chunks are written at their offset, download URLs are escaped, listing a run without artifacts no longer crashes
1. Poll backoff reaches `fetch_interval_max`, proxy passwords are masked in more forms, secrets are also masked in step names and in their quoted form in the runner log, a failed final report is logged
1. On Windows hosts a differently cased unsecure-commands opt-in or proxy variable counts, and an early cancel no longer leaks a job object handle
1. Interactive `register` prompts for a missing token and stops on SIGTERM, `exec --list --detect-event` no longer panics without events, `config set` works on `cache.s3` keys

Zettat123andsilverwind 755af87095 enhance(k8s): reach Kubernetes services by their id when it is a DNS subdomain (#1320)
On Kubernetes a service is reached by its id made a DNS label, so some service ids might become unreachable. For example, the `devstoreaccount1.azurite.local` service of Gitea's [MSSQL tests](https://github.com/go-gitea/gitea/blob/2fe74d3cdd5184a7e22e32e47772caa78d077489/.github/workflows/pull-db-tests.yml#L229) is only in the pod's hosts as `devstoreaccount1-azurite-local`, while the tests connect to the id as written. Container names must be DNS labels, but `hostAliases` accepts DNS subdomains, so an id that is one is now added there too, and to `no_proxy`, as on Docker where a service is reached by its id.

The warning for a service not reachable by its id now also covers ids that differ only in case, as Kubernetes hostnames are lowercase.

Lunny Xiaoandbircni e0ef637805 refactor(logging): replace the logrus backend with log/slog (#1304)
Log through `log/slog`, with a console `slog.Handler` that writes the text the runner has always written (sorted `key=value` fields on a plain stream, a colored prefix on a terminal), so nothing changes for users. I compared its output byte for byte with logrus's `TextFormatter` over plain, colored, timestamped and caller cases.

Why not `slog.TextHandler`: its output differs from what users and their log parsers see today, and `ReplaceAttr` cannot close the gap.
- level is `WARN` where logrus wrote `warning`, and time has milliseconds and no quotes
- fields keep call order instead of being sorted
- the caller is one `source=` key, where the runner writes `func=` and `file=` (reshaped by `callPrettyfier`), and `ReplaceAttr` returns a single attribute
- no colored prefix on a terminal
- no hook to rewrite a whole formatted line, which the process-wide secret masking relies on

Libraries that log through logrus's global logger (the workflow model, the Docker client) are forwarded to the process-wide logger, so they keep following its level, format and secret masking. This is why logrus stays in `go.mod`.

8b14a38d4a enhance!: send OTLP metrics under OpenTelemetry semantic conventions, add runner state (#1282)
Sends the OTLP metrics under [OpenTelemetry semantic convention](https://opentelemetry.io/docs/specs/semconv/) names where the runner's data matches the definition, like `cicd.worker.count`, `cicd.system.errors` and the `go.*` and `process.*` runtime metrics, and under `gitea.runner.*` otherwise. OTel dashboards then work without remapping, as they already do for the traces from https://gitea.com/gitea/runner/pulls/1206.

Adds a `gitea_runner_state` gauge (`busy`, `idle`, `unavailable`), and `/readyz` now fails once the runner shuts down.

**Breaking**

1. OTLP metric names, units, types and attribute values change, and the info and start time metrics move to resource attributes.
1. Prometheus `gitea_runner_client_errors_total` gains a `code` label, and `gitea_runner_job_total` counts jobs stopped by `runner.timeout` as `timeout` instead of `failure`.

f963e9cfe8 enhance: support client certificates for mutual TLS (#1273)
Add `runner.client_cert_file` and `runner.client_key_file` for Gitea instances that require mutual TLS. The runner presents the certificate on its RPCs, job summary uploads, and the action, reusable workflow and `builtin:checkout` clones from the instance. The files are read on use, so renewed certificates apply without a restart. Job steps do not get them. An incomplete or mismatched pair fails startup.

Clones now decide the token, client certificate and `runner.insecure` with one host check, which also gives reusable workflow clones the TLS settings they lacked. `runner.insecure` still only covers the registered address.

329115b148 enhance(config): expand environment values (#1274)
Config values can reference the runner's environment as `${NAME}`, for example `capacity: ${RUNNER_CAPACITY}`, so container deployments can configure the runner without templating the file. An unset `NAME` fails the load instead of silently becoming empty, and `$${NAME}` writes a literal `${NAME}`. Keys are never expanded.

Breaking: an existing value containing `${NAME}`, such as a shell command in a Kubernetes `pod_template`, now needs `$${NAME}`.

27e9b4de87 fix!: use the git CLI for action clones and make builtin:checkout match actions/checkout (#1277)
The runner now uses the `git` command line instead of go-git to download actions and reusable workflows. go-git had recurring bugs and does not support SHA-256 repositories, and full clones of actions are several times faster.

`builtin:checkout` now runs `git` where the job runs and behaves like `actions/checkout`:

1. A branch is checked out as a local branch tracking `origin`, tag and pull request runs keep their ref, and a triggering tag that moved fails the step.
1. Later steps can fetch and push with the persisted token or SSH key.
1. It supports the `ssh-*`, `lfs`, `submodules`, `sparse-checkout`, `filter`, `fetch-tags`, `clean`, `persist-credentials`, `show-progress` and `set-safe-directory` inputs and the `ref` and `commit` outputs.
1. SHA-256 repositories work for actions, reusable workflows and `builtin:checkout`.

Git keeps the token off its command line, ignores `GIT_DIR` and similar variables inherited by the runner, and keeps action files LF regardless of `core.autocrlf`. A cancelled job lets git remove its lock files.

This is a breaking change: the runner needs Git 2.34.1 or newer on its `PATH`, and so do job images that use `builtin:checkout`. The official runner images include it.

568f89d186 enhance: export the Prometheus metrics over OpenTelemetry (#1248)
Push the runner's Prometheus metrics to the OTLP endpoint next to the job traces, so both land in the same backend.

The `/metrics` registry is converted as the [Prometheus compatibility spec](https://opentelemetry.io/docs/specs/otel/compatibility/prometheus_and_openmetrics/) describes and sent through the existing gRPC-free client, so names stay unchanged and no second metrics stack is linked. Metrics are on by default and pushed every interval and once on shutdown, so ephemeral runners report too.

New standard variables, each `OTEL_EXPORTER_OTLP_*` one with `TRACES` and `METRICS` variants:

- `OTEL_METRICS_EXPORTER`, `none` turns metrics off
- `OTEL_METRIC_EXPORT_INTERVAL`, `OTEL_METRIC_EXPORT_TIMEOUT`
- `OTEL_EXPORTER_OTLP_TIMEOUT`, `OTEL_EXPORTER_OTLP_COMPRESSION`
- `OTEL_EXPORTER_OTLP_CERTIFICATE`, `OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE`, `OTEL_EXPORTER_OTLP_CLIENT_KEY`

0cedd98051 feat: add Kubernetes backend (#1260)
Adds a Kubernetes backend. A `name:kubernetes://image` label runs the job as one pod through the Kubernetes API, with services as containers of the same pod. Step env is exported by a script sent over exec stdin, keeping it out of the pod spec and process arguments, and service env goes into a per-job Secret. Docker actions and container options are rejected. See `docs/kubernetes.md`.

Operators shape job pods with `kubernetes.pod_template`, with per-label `pod_templates` merged in `runs-on` order and a `$services` entry for service containers. The idle cleanup removes pods and Secrets a runner left behind.

The client calls the Kubernetes API directly and runs step commands over `coder/websocket` (same dependency used in gitea) instead of pulling in the heavyweight `kubernetes/client-go`. Includes an e2e test against k3s.

1952e5cdb6 feat: OpenTelemetry tracing (#1206)
Adds OpenTelemetry tracing, configured through the standard `OTEL_*` environment variables and off until an OTLP endpoint is set.

![image.png](https://gitea.com/attachments/c4b49cdf-a32d-403c-94e9-30cd06ee6477)

Each job becomes a trace with a span per step, so operators can see where CI time goes in their existing observability backend. Jobs receive only `TRACEPARENT`, so instrumented tools inside them join the trace without seeing the collector's credentials. Metrics stay on the Prometheus endpoint, which a collector can scrape. See [docs/telemetry.md](https://gitea.com/wmTJc9IK0Q/runner/src/branch/otel/docs/telemetry.md) for setup and security notes.

Also keeps `GITHUB_SHA` and `GITHUB_REF` fixed for a whole run when HEAD moves during `exec` runs and the act tests.

7ad12038d1 feat(runner): add built-in actions framework with checkout (#871)
Adds built-in actions, native Go actions shipped with the runner and selected with `uses: builtin:<name>`. Jobs need no action download and no Node in their image.

The first one is `builtin:checkout`, a subset of `actions/checkout` with `repository`, `ref`, `token`, `path` and `fetch-depth`. Other inputs fail the step. The runner clones shallowly on its host and copies the tree into the job, while `gitea-runner exec` copies the local working directory for the workflow's own ref.

`actions/checkout` and other remote actions are unchanged. A clone ref of `HEAD` now shallow-clones the remote's default branch, which checkout uses for other repositories.
