A simple library for handling docker commands with python.

• pip install --upgrade DockerBuildSystem

• Include DockerBuildSystem tools:

from DockerBuildSystem import DockerComposeTools, DockerImageTools, DockerSwarmTools, TerminalTools, VersionTools

• Merge, build and run docker-compose.*.yml files:

composeFiles = [
    'docker-compose.yml',
    'docker-compose.build.yml',
    'docker-compose.override.yml'
]
mergedComposeFile = "docker-compose.generated.dev.yml"
DockerComposeTools.MergeComposeFiles(composeFiles, mergedComposeFile)
DockerComposeTools.DockerComposeBuild([mergedComposeFile])
DockerComposeTools.DockerComposeUp([mergedComposeFile])

• Push and pull images in docker-compose.*.yml files, including additional latest tag:

composeFiles = [
    'docker-compose.yml'
]
DockerComposeTools.DockerComposePush(composeFiles)
DockerComposeTools.PublishDockerImagesWithNewTag(composeFiles, 'latest')
DockerComposeTools.DockerComposePull(composeFiles)

• Execute test projects in Docker containers and raise exception if container exits with error code due to failing tests:

composeFiles = [
    'docker-compose.tests.yml'
]
testContainerNames = [
    'lab-services-tests'
]
DockerComposeTools.ExecuteComposeTests(composeFiles, testContainerNames)

• Load set of specific environment variables from a *.env file:

TerminalTools.LoadEnvironmentVariables('path_to/variables.env')

• Export top-most version from CHANGELOG.md file (see the example folder) as an environment variable:

VersionTools.ExportVersionFromChangelogToEnvironment("path_to/CHANGELOG.md", "version")

• Optionally export versionmajor and versionminor based on the top-most version from CHANGELOG.md file as an environment variable:

VersionTools.ExportVersionFromChangelogToEnvironment("path_to/CHANGELOG.md", "version", "versionmajor", "versionminor")

• to use the DockerComposeTools.PromoteDockerImages functionality, provide the following parameters:
• composeFile - the compose file containing theimages that should be promoted
• targetTags - the tags you want to use when you push the image to the new feed
• sourceFeed - the feed you want to pull the images from (should match the compose file)
• targetFeed - the feed you want to push to
• user - used for authenticating to sourceFeed and targetFeed
• password - used for authenticating to sourceFeed and targetFeed
• dryRun - boolean. True if you want to do a dryRun, i.e. print what would have happened

Please have a look at an example of use here:

• https://github.com/hansehe/DockerBuildSystem/tree/master/example

• Docker:
  • https://www.docker.com/get-docker
• Install Dependencies:
  • pip install -r requirements.txt

• The pip package may be located at:
  • https://pypi.org/project/DockerBuildSystem

1. Configure setup.py with new version.
2. Install build tools: pip install twine wheel
3. Build: python setup.py bdist_wheel
4. Check: twine check dist/*
5. Publish: twine upload dist/*

1. Build: python setup.py bdist_wheel
2. Install from local file with force-reinstall and no-cache-dir options to force reinstallation when you have changed the code without changing the version number: python -m pip install path\to\yourgitrepo\DockerBuildSystem\dist\DockerBuildSystem-1.1.43-py2.py3-none-any.whl --force-reinstall --no-cache-dir

• python -m unittest discover -p Test.py
