Docker has this thing where they rebrand the debian package name once a year, and as YUM doesn't resolve anything like a "Provides" field, this is the best we can do (unless they all required the same metapackage).
Note that now we can't ensure a specific minor docker version via RPM, though I feel as though if you choose a crappy OS/package manager and we fail you, thats on you, not Dokku.
Closes#2732
- Requires docker, git, and package_cloud gems
- Requires the PACKAGECLOUD_API_TOKEN environment variable
- Builds both a deb and rpm, pushing both to packagecloud
- Upgrades the golang build environment to 1.7.5
- Combines both build Dockerfiles into a single, generic env
- Fixes issue where internal-functions file for tar plugin was not executable
- Ensures that built plugins have a callback to clean up their source files before packaging
- Adds support for “betafish” releases, which are untested versions of Dokku that are available via a separate packagecloud repository.
