Docker CLI Sugar

A variety of command line tools to help with common docker tasks.

These commands require bash on the host, but support containers with bash and/or just sh.

Install

Requires bash.

git clone https://github.com/avirshup/docker-cli-sugar
export PATH=$(pwd)/docker-cli-sugar:${PATH}

# Enable for all your bash sessions:
echo "export PATH=$(pwd)/docker-cli-sugar:${PATH}" >> ~/.bash_profile

dshell [image-or-container-name-or-id]

Launch a shell in an image or container (whether running or stopped). Launches bash by preference, otherwise sh.

[...]

Shell in an image

[host]$ dshell centos
Running "docker run -it --entrypoint=sh centos"
shell: bash
[container]$ yum update  # or whatever
[...]

Examining a stopped container

[host]$ docker run --name "stopped-container" \
             alpine sh -c "echo hello world > hello.txt"
[host]$ dshell stopped-container
Container is stopped. Committing to image
Running "docker commit stopped-container dshell-temp-container"
sha256:[...]
