Pyocker

Description

• Docker images have Base Images, and a Base Image also has another Base image.
• You may want to re-build ImageA before building ImageB which will be built based on ImageA.

Pyocker enables static definition of Dockerfile dependencies and selective build/push of docker images.

TODO

• Enable use of Dockerfiles in user-selected directories for each image
• Integration with dockerfile_composer
• Registry authentication
• Check if actual dependency described in Dockerfiles match dependency definitions
• Add comments
• Loggin into files

Requirements

• Docker
