GitHub Metadata Action for Docker Buildx Bake.
This action also handles a bake definition file that can be used with the Docker Bake action. You just have to declare an empty target named github-metadata-action and inherit from it.
// docker-bake.hcl
target "docker-metadata-action" {}
target "github-metadata-action" {}
target "build" {
inherits = ["docker-metadata-action", "github-metadata-action"]
context = "./"
dockerfile = "Dockerfile"
platforms = [
"linux/amd64",
"linux/arm/v6",
"linux/arm/v7",
"linux/arm64",
"linux/386"
]
