Docker pipe supports either image templates or image with tag templates.
Image template must be configured, no default is provided.
If image name is still used, provide default for tag templates,
for backward compatibility.
Docker config takes a list of image templates as image specification.
Existing config with image and tag templates are still accepted,
but will display deprecation notice.
Either image templates or image + tag templates is supported,
but not both at the same time.
This will also support publishing to multiple docker registries (#832).
Deprecated:
- `docker.image`
- `docker.tag_templates`
Created a list of registries based on the docker image name and
additional registries. Image is then tagged with all permutations
of registry and tags.
See #832
This now allows us to use things like the ProjectName as variables
in our docker image name. This is especially helpful when trying to
make the `.goreleaser.yml` as generic as possible.
I enhanced `BuildFlagTemplates` field in Docker image config to accept
templates. Build flags are tested by checking for images created with
labels applied through templates.
See #813
I added `BuildFlags` field to Docker image config. Docker pipe is
updated to append build flags to the `docker build` command.
Build flags are not validated, leaving it Docker to error
when given an unknown flag.
See #813
