+# Podman Build And Publish Action
+
+Composite action that builds and optionally pushes OCI images with Podman to `registry.noctrl.eu`.
+
+## Inputs
+
+- `image-name` (required): repository path, for example `noctrl/gitea-runner`
+- `tags` (required): newline, comma, or space separated tags
+- `context` (optional, default `.`): build context
+- `containerfile` (optional, default `Containerfile`): containerfile path
+- `build-args` (optional): newline-separated `KEY=VALUE`
+- `push` (optional, default `true`): whether to push image tags
+
+## Required Secrets
+
+The following repository secrets must be defined to push images:
+- `REGISTRY_USERNAME`: registry authentication username
+- `REGISTRY_PASSWORD`: registry authentication password
+
+The action uses fixed Podman defaults matching the runner workflows:
+- root: `${RUNNER_TEMP}/podman-root`
+- runroot: `${RUNNER_TEMP}/podman-runroot`
+- storage driver: `vfs`
+- build isolation: `chroot`
+- registry: `registry.noctrl.eu` (hardcoded)
+
+## Example
+
+```yaml
+jobs:
+  build-and-push:
+    runs-on: [linux, build]
+    steps:
+      - name: Checkout
+        uses: actions/checkout@v4
+
+      - name: Build and push image
+        uses: https://gitea.noctrl.eu/noctrl/actions/podman-build-publish@v1
+        with:
+          image-name: noctrl/gitea-runner
+          tags: |
+            latest
+            sha-${{ github.sha }}
+          context: .
+          containerfile: Containerfile
+          build-args: |
+            ACT_RUNNER_VERSION=0.2.11
+          push: "true"
+```
+
+> **Note:** The action accesses `${{ secrets.REGISTRY_USERNAME }}` and `${{ secrets.REGISTRY_PASSWORD }}` from the calling repository's secrets context. These must be defined in the caller's repository settings.
