boatswain 1.0.4

Boatswain
Boatswain is a simple build system for docker images.
It is especially usefull when you have multiple docker images that
depend on each other.


Installation
Boatswain is a simple python script you can install with pip
$ pip install boatswain


Usage
Create a file called boatswain.yml for your project with the following
syntax, which is heavily based on docker-compose.
version: 1.0 # The version of the boatswain yaml
organisation: boatswain # Your dockerhub organisation
images:
image1:pytest: # the key will be used to tag the image
context: docker/image1 # The path of the dockerfile
image2:pytest:
context: docker/image2
from: image1:pytest # This image depends on the other image
image3:pytest:
context: docker/image3
from: image2:pytest
image4:pytest:
context: docker/image4
tag: image12:pytest # This image will be tagged with this

Building
You can build the images defined in the boatswain file using the following
command. This invokes the docker build process for each image in the order
so the dependencies are built before the dependent image.
$ boatswain build


Cleaning
You can clean the images that are defined in the boatswain file.
$ boatswain clean


Pushing
You can push the built images to dockerhub using the push command.
It will be pushed to organisation/imagetag on dockerhub.
$ boatswain push



Extra Options

-h
Display the options

-q, --quiet
Don’t display any output

-k, --keep_building
Keep building images even if an error occurs

--dryrun
Do not actually execute the command, just go through the motions

-b <boatswain_file>, --boatswain_file <boatswain_file>
Override the default boatswain file (boatswain.yml)

-f, --force
Force building the images, even if they already exist
(only for build)




Debugging your build
When your build does not go the way you expected boatswain
can display some more information by using:

-v
Verbose mode, displays a build progress for each image

-vv
Very verbose mode, displays the output of the docker build process

--debug
Debug mode, displays debug information of boatswain
as well as the output of the docker build process
