Woodpecker CI plugin to build multiarch Docker images with depot.

Features

• Build without push
• Use custom registries (Only supporting Docker Hub for now)
• Build based on existing tags when needed
• Push to multiple registries/repos

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/<registry-value>/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
registry	https://index.docker.io/v1/	sets docker registry to authenticate with
dockerfile	Dockerfile	sets dockerfile to use for the image build
tag/tags	none	sets repository tags to use for the image
platforms	none	sets target platform for build

auto_tag

If set to true, it will use the default_tag ("latest") on tag event or default branch. If it's a tag event it will also assume sem versioning and add tags accordingly (x, x.x and x.x.x). If it's not a tag event, and no default branch, automated tags are skipped.
