`dockerprep`

Prepares a docker project in the current directory, setting up a structure that makes it easier to build/rebuild/debug and run developing projects.

Usage

dockerprep SOURCE_IMAGE[:TAG] REPO TAG NAME

"Installation"

Linux:

alias dockerprep='docker run --rm -it --user="$(id -u):$(id -g)" --volume="$(pwd -P):/project" electricwarr/dockerprep:0.9'

NB: --user is needed here to avoid writing all files as root

MacOS:

alias dockerprep='docker run --rm -it --volume="$(pwd -P):/project" electricwarr/dockerprep:0.9'

The electricwarr/dockerprep image will be downloaded on the first invocation.

You can find the latest version on Docker Hub:

https://hub.docker.com/u/electricwarr/

Function

When run in an empty directory, dockerprep will create a new docker project based on input parameters. These parameters will be saved to a config file, project.cfg, as well as preserved to a hidden file .dockerprep.cfg. dockerprep checks for .dockerprep.cfg to prevent losing data if run in a non-empty directory.

Versioning

x.y, where x is incremented for breaking changes (after 1.0) and y other changes.

Future

Give the option to abort before overwriting any files
- dockerprep currently will refuse to run on finding .dockerprep.cfg
- If run in an existing project without .dockerprep.cfg, existing files (eg. Dockerfile) can be overwritten without warning
Run git init, git add . and git commit -m 'initial commit (dockerprep)' IFF git is installed and the current directory is not part of a git repository.

Questions

Should this be in Go? Python? Node.js?

Thinking of rewriting in another language (probably Go) to be less dependent on shell environment.
