Bashbrew (bashbrew)

Jenkins Build Status

$ bashbrew --help
NAME:
   bashbrew - canonical build tool for the official images

USAGE:
   bashbrew [global options] command [command options] [arguments...]

COMMANDS:
     list   list repo:tag combinations for a given repo
     build  build (and tag) repo:tag combinations for a given repo
     tag    tag repo:tag into a namespace (especially for pushing)
     push   push namespace/repo:tag (see also "tag")

   plumbing:
     children  print the repos built FROM a given repo or repo:tag
     parents   print the repos this repo or repo:tag is FROM
     cat       print manifest contents for repo or repo:tag
     from      print FROM for repo:tag

GLOBAL OPTIONS:
   --debug                  enable more output (esp. all "docker build" output instead of only output on failure) [$BASHBREW_DEBUG]
   --no-sort                do not apply any sorting, even via --build-order
   --constraint value       build constraints (see Constraints in Manifest2822Entry)
   --exclusive-constraints  skip entries which do not have Constraints
   --config value           where default "flags" configuration can be overridden more persistently (default: "/home/tianon/.config/bashbrew") [$BASHBREW_CONFIG]
   --library value          where the bodies are buried (default: "/home/tianon/docker/official-images/library") [$BASHBREW_LIBRARY]
   --cache value            where the git wizardry is stashed (default: "/home/tianon/.cache/bashbrew") [$BASHBREW_CACHE]
   --help, -h, -?           show help

Building

Go version 1.6 or above is required for compilation of Bashbrew.

Bashbrew itself is built using gb (github.com/constabulary/gb).

Once in the go subdirectory, gb build should produce go/bin/bashbrew, ready for use.

Usage

Docker version 1.10 or above is required for use of Bashbrew.

In general, bashbrew build some-repo or bashbrew build ./some-file should be sufficient for using the tool at a surface level, especially for testing. For more complex usage, please see the built-in help (bashbrew --help, bashbrew build --help, etc).

Configuration

The default "flags" configuration is in ~/.config/bashbrew/flags, but the base path can be overridden with --config or BASHBREW_CONFIG (technically, the full path to the flags configuration file is ${BASHBREW_CONFIG:-${XDG_CONFIG_HOME:-$HOME/.config}/bashbrew}/flags).

To set a default namespace for specific commands only:

Commands: tag, push
Namespace: officialstaging

To set a default namespace for all commands:

Namespace: jsmith

A more complex example:

# comments are allowed anywhere (and are ignored)
Library: /mnt/docker/official-images/library
Cache: /mnt/docker/bashbrew-cache
Constraints: aufs, docker-1.9, tianon
ExclusiveConstraints: true

# namespace just "tag" and "push" (not "build")
Commands: tag, push
Namespace: tianon

Commands: list
ApplyConstraints: true

Commands: tag
Debug: true

In this example, bashbrew tag will get both Namespace and Debug applied.
