build: publish Docker images with GoReleaser - #1879
Conversation
Build and push the Docker image in the release workflow, and remove the separate Docker Hub workflow that rebuilt the image after "🎉 Release Binary" finished. GoReleaser now builds the image with dockers_v2 from the binaries it compiles in the same run. The Dockerfile no longer builds katana. It copies $TARGETPLATFORM/katana from the GoReleaser build context and sets OCI labels. dockers_v2 replaces the deprecated dockers and docker_manifests. Rename release-binary.yml to release.yml and the workflow to "🎉 Release", since it now publishes images too. The workflow logs in to Docker Hub and switches from goreleaser/goreleaser-action to projectdiscovery/actions/goreleaser. With release: true, the goreleaser action sets up QEMU and Buildx before it runs goreleaser release. Tag images with the release tag, vX.Y, vX and latest. The old workflow pushed only the release tag and latest. Disable image builds for snapshot runs in CI, where runners may lack QEMU. Local snapshot runs still build images. Removing the old workflow also removes its workflow_dispatch trigger, so images can no longer be re-pushed without a release run. Closes #1877 Signed-off-by: Dwi Siswanto <git@dw1.io>

This matches the request. The image is built from the release binaries in the same GoReleaser run, with the release tag, vX.Y, vX, and latest.

Run the crawler as a non-root user.
Dockerfile has no USER instruction, so the container runs katana as root by default. Add a dedicated user, set USER, and ensure Chromium's profile and cache paths are writable by that user.

Pin the Alpine base image for release builds.
The release workflow can run for a version tag or through workflow_dispatch, and GoReleaser publishes the exact {{ .Tag }} image tag. A later rebuild can resolve alpine:latest to a different Alpine release and install different apk packages. This can change the runtime of an existing Katana release. Use the validated fixed release or an immutable digest.

Proposed changes
Build and push the Docker image in the release workflow, and remove the separate Docker Hub workflow that rebuilt the image after "🎉 Release Binary" finished.
GoReleaser now builds the image with dockers_v2 from the binaries it compiles in the same run. The Dockerfile no longer builds katana. It copies $TARGETPLATFORM/katana from the GoReleaser build context and sets OCI labels. dockers_v2 replaces the deprecated dockers and docker_manifests.
Rename release-binary.yml to release.yml and the workflow to "🎉 Release", since it now publishes images too. The workflow logs in to Docker Hub and switches from goreleaser/goreleaser-action to projectdiscovery/actions/goreleaser. With release: true, the goreleaser action sets up QEMU and Buildx before it runs goreleaser release.
Tag images with the release tag, vX.Y, vX and latest. The old workflow pushed only the release tag and latest.
Disable image builds for snapshot runs in CI, where runners may lack QEMU. Local snapshot runs still build images.
Removing the old workflow also removes its workflow_dispatch trigger, so images can no longer be re-pushed without a release run.

Proof
goreleaser checkandactionlint .github/workflows/release.ymlpass.goreleaser release --snapshot --cleanpasses.katana -versionprints v1.8.0;dig, Chromium and the CA certificates are present, and a headless crawl with-system-chrome-path /usr/bin/chromium-browserworks.-headless -system-chromefinds nothing, as it does in the current image (-system-chrome is ignored with -headless, so headless crawls in the Docker image find nothing #1878).RUNsteps, so I checked that the image's binary is arm64 and byte-identical to the GoReleaser build, that it prints v1.8.0 under qemu-aarch64, and that Alpine v3.24's aarch64 index has bind-tools, ca-certificates and chromium.Checklist
