GLOBAL OPTIONS: --debug enable more output (esp. all "docker build" output instead of only output on failure) [$BASHBREW_DEBUG] --no-sort do not apply any sorting, even via --build-order --arch value the current platform architecture (default: "amd64") [$BASHBREW_ARCH] --namespace value a repo namespace to act upon/in [$BASHBREW_NAMESPACE] --constraint value build constraints (see Constraints in Manifest2822Entry) [$BASHBREW_CONSTRAINTS] --exclusive-constraints skip entries which do not have Constraints --arch-namespace value architecture to push namespace mappings for creating indexes/manifest lists ("arch=namespace" ala "s390x=tianons390x") [$BASHBREW_ARCH_NAMESPACES] --config value where default "flags" configuration can be overridden more persistently (default: "/home/tianon/.config/bashbrew") [$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 --version, -v print the version

Installing

Pre-built binaries are available to download from Jenkins (for all supported architectures).

(For building bashbrew yourself, it's a pretty standard Go application.)

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 default 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:

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 (options are additive).
