This plugin is a fork of [thegeeklab/drone-docker-buildx](https://github.com/thegeeklab/drone-docker-buildx/) which itself is a fork of [drone-plugins/drone-docker](https://github.com/drone-plugins/drone-docker). You can find the full documentation at You can find the full documentation at [woodpecker-plugins.codeberg.page](https://woodpecker-plugins.codeberg.page/plugins/drone-docker-buildx). ## Features - Build without push - Use custom registries - Build based on existing tags when needed - Push to multible registries/repos It will automatically generate buildkit configuration to use custom CA certificate if following conditions are met: - Setting `buildkit_config` is not set - Custom `registry`/`logins` value is provided - File exists `/etc/docker/certs.d//ca.crt` > NB! To mount custom CA you can use Woodpecker CI runner configuration environment `WOODPECKER_BACKEND_DOCKER_VOLUMES` with value `/etc/ssl/certs:/etc/ssl/certs:ro,/etc/docker/certs.d:/etc/docker/certs.d:ro`. And have created file `/etc/docker/certs.d//ca.crt` with CA certificate on runner server host. ## Settings | Settings Name | Default | Description | --------------------------| ----------------- | -------------------------------------------- | `dry-run` | `false` | disables docker push | `repo` | *none* | sets repository name for the image (can be a list) | `username` | *none* | sets username to authenticates with | `password` | *none* | sets password / token to authenticates with | `email` | *none* | sets email address to authenticates with | `registry` | `https://index.docker.io/v1/` | sets docker registry to authenticate with | `dockerfile` | `Dockerfile` | sets dockerfile to use for the image build | `tag`/`tags` | @".tags" | sets repository tags to use for the image | `platforms` | *none* | sets target platform for build ## Examples ```yml publish-next-agent: image: woodpeckerci/plugin-docker-buildx secrets: [docker_username, docker_password] settings: repo: woodpeckerci/woodpecker-agent dockerfile: docker/Dockerfile.agent.multiarch platforms: windows/amd64,darwin/amd64,darwin/arm64,freebsd/amd64,linux/amd64,linux/arm64/v8 tag: next when: branch: ${CI_REPO_DEFAULT_BRANCH} event: push ``` ```yml publish: image: woodpeckerci/plugin-docker-buildx settings: platforms: linux/386,linux/amd64,linux/arm/v6,linux/arm64/v8,linux/ppc64le,linux/riscv64,linux/s390x repo: codeberg.org/${CI_REPO_OWNER}/hello registry: codeberg.org tags: latest username: ${CI_REPO_OWNER} password: from_secret: cb_token ``` ```yml docker-build: image: woodpeckerci/plugin-docker-buildx settings: repo: codeberg.org/${CI_REPO_OWNER}/hello registry: codeberg.org dry_run: true output: type=oci,dest=${CI_REPO_OWNER}-hello.tar ``` ## Advanced Settings | Settings Name | Default | Description | --------------------------| ----------------- | -------------------------------------------- | `mirror` | *none* | sets a registry mirror to pull images | `storage_driver` | *none* | sets the docker daemon storage driver | `storage_path` | `/var/lib/docker` | sets the docker daemon storage path | `bip` | *none* | allows the docker daemon to bride ip address | `mtu` | *none* | sets docker daemon custom mtu setting | `custom_dns` | *none* | sets custom docker daemon dns server | `custom_dns_search` | *none* | sets custom docker daemon dns search domain | `insecure` | `false` | allows the docker daemon to use insecure registries | `ipv6` | `false` | enables docker daemon IPv6 support | `experimental` | `false` | enables docker daemon experimental mode | `debug` | `false` | enables verbose debug mode for the docker daemon | `daemon_off` | `false` | disables the startup of the docker daemon | `buildkit_config` | *none* | sets content of the docker [buildkit TOML config](https://github.com/moby/buildkit/blob/master/docs/buildkitd.toml.md) | `context` | `.` | sets the path of the build context to use | `default_tags`/`auto_tag` | `false` | generates tag names automatically based on git branch and git tag, tags supplied via `tags` are additionally added to the auto_tags without suffix | `default_suffix"`/`auto_tag_suffix`| *none* | generates tag names with the given suffix | `default_tag` | `latest` | overrides the default tag name used when generating with `auto_tag` enabled | `label`/`labels` | *none* | sets labels to use for the image in format `=` | `default_labels`/`auto_labels` | `true` | sets docker image labels based on git information | `build_args` | *none* | sets custom build arguments for the build | `build_args_from_env` | *none* | forwards environment variables as custom arguments to the build | `quiet` | `false` | enables suppression of the build output | `target` | *none* | sets the build target to use | `cache_from` | *none* | sets images to consider as cache sources | `pull_image` | `true` | enforces to pull base image at build time | `compress` | `false` | enables compression of the build context using gzip | `config` | *none* | sets content of the docker daemon json config | `purge` | `true` | enables cleanup of the docker environment at the end of a build | `no_cache` | `false` | disables the usage of cached intermediate containers | `add_host` | *none* | sets additional host:ip mapping | `output` | *none* | sets build output in format `type=[,=]` | `logins` | *none* | option to log into multible registrys ## Multi registry push example Only supported with `woodpecker >= 1.0.0` (next-da997fa3). ```yml settings: repo: a6543/tmp,codeberg.org/6543/tmp tag: demo logins: - registry: https://index.docker.io/v1/ username: a6543 password: from_secret: docker_token - registry: https://codeberg.org username: "6543" password: from_secret: cb_token ```
