Wrapped Docker CLI

This wraps the Docker CLI so that it establishes saner defaults for my own needs.

What this does

• docker run will set to logging to none and -it by default

• docker rm is forced

  • and remove anonmized volumes

• docker nuke will remove all running containers and associated volumes (no warning, primarilly used for development when I just want a clean slate without doing a full reset)

• docker ls maps to docker ps

• docker ps will actually call docker inspect then render the data using github.com/jedib0t/go-pretty.

  • Primarily because I want to know WHEN the bloody container started,
  • how long it took to start rather than about a minute ago.
  • Show ports only if I am not running in service mode

• docker service restart maps to docker service update --force

• docker service ls shows only relavent columns

  • drop :latest if that's the image tag
  • use github.com/jedib0t/go-pretty to render the table
  • --down to list services that are not fully up

• docker service env shows the environment variables

• docker service ps without the service list will do all services

  • if primary is running and is desired to be running, don't bother showing the others

• docker ptag to tag and push image in one command

  • -p to add support for generating a patch tag

• docker ports lists exposed local port mappings with some specific tweaks for HTTPm that way I can simply ctrl-click the text on the terminal.

  • if container has an image containing httpd or ngnix display as http://localhost:{port}
  • if container internal port is 80, 3000 or 8080 display as http://localhost:{port}

• docker build adds implicit secrets to the build.

  • docker build maps to docker buildx build --load which will use the builder specified by docker buildx use.
  • init-gradle == $HOME/.gradle/init.gradle
  • npmrc == $HOME/.npmrc
  • settings-xml == $HOME/.mvn/settings.xml
  • aws-credentials == $HOME/.aws/credentials

• docker bash runs /bin/bash given a container ID

• docker sh runs /bin/sh given a container ID

• docker logs like docker logs but starts tailing

  • supports a positional paramter which represents since without having to type in --since
  • the command usage is docker tail [since] [containerID]

• docker env [containerID] dumps the environment variables for the container sorted

• docker mnt . mounts the current directory to /mnt and runs alpine image (note any relative path can work)

  • docker mnt . [image] mounts the current directory to /mnt and runs the image specified
  • docker mnt . [image] [cmd...] mounts the current directory to /mnt and runs the image specified with the command
  • docker mnt [volume] [image] mounts the named volume to /mnt and runs the image specified
  • docker mnt [volume] [image] [cmd...] mounts the named volume to /mnt and runs the image specified with the command

• docker service push <service> <image> replaces the image of the service if image is not provided it pulls and then does the update to ensure it is the latest copy. It will also add --with-registry-auth as appropriate

• docker use <context> maps to docker context use

• docker context use allows docker context use <target> which uses the target rather than the context name.

  • automatically create the context if it does not exist

• docker service --help should call docker service --help but append the extra commands

• docker service inspect shows data

  • gets rid of the previous spec
  • use network names rather than the IDs

• docker service logs like docker service logs but starts tailing, passes --raw

  • supports a positional paramter which represents since without having to type in --since

• docker du shows disk usage stats in JSON

• docker stat runs docker stats --no-stream with sane columns (i.e. no ID)

• docker stats runs with sane columns (i.e. no ID) and hopefully less flashing

• docker context create <name> <dockerhost> maps to docker context create <name> --docker "host=<dockerhost>"

• docker context create <dockerhost> maps to docker context create <host portion of dockerhost> --docker "host=<dockerhost>"

• Special handling for ridiculously long image names, specifically "ghcr.io/open-telemetry/opentelemetry-collector-releases/opentelemetry-collector-contrib"

Architecture

• Use Cobra to manage the CLI
• Use the CLI for the most part until they have a package that would handle DOCKER_HOST
• output will be in JSON like the CLI because there's no yaml mappings in the Docker types
