Drone-Makisu plugin

Executes container builds in Drone CI using Makisu (https://github.com/uber/makisu)

Attempts to mimic the arguments for the regular docker plugin (http://plugins.drone.io/drone-plugins/drone-docker/) as closely as possible, including support for a .tags file which will be used if no tags are specified in settings.

Things to know

AWS ECR

this plugin tries to be smart about pushing to AWS ECR registries. If the registry hostname looks like an AWS ECR one, it automatically tries to set up the necessary auth settings. All you need to do is to use environment variables to specify AWS credentials, if the build isn't running with a role that has implicit access to AWS.

Docker hub

The syntax is a bit weird, since it's necessary to specify the docker hub host (index.docker.io). See examples down below for details

Pusing to other registries than Docker Hub and AWS ECR

Not implemented just yet - coming shortly!

Parameters

• repo: required. Given the image name trondhindenes/drone-makisu-plugin:latest, the repo field would be drone-makisu-plugin. If this parameter is specified as xx/xx and registry isnt specified, the field will be automatically split into registry and repo.
• tags: optional. List of tags to use on the image. Defaults to 'latest'. If this parameter is omitted, and a file called .tags is found in the local dir, that file will be used instead. It should contain a comma-separated list of tags to use.
• build_args: optional. Dict of build args to use when building the image
• build_args_from_env: optional. List of env vars to convert to build args
• registry: optional. where to push the image. See also repo above
• dockerfile: optional, defaults to Dockerfile
• debug: optional. Set it to true to print more info
• storage: optional. specify cache dir for layers
• commit: optional. Defaults to implicit. Set it to explicit to use makisu's smart caching feature.
