Aliases I use for docker commands

Here are some aliases I use on a daily basis for docker and docker compose.

It goes without saying that these should be used alongside with tools like reverse history search.

# docker
alias dil='docker image ls'
alias dps='docker ps'
alias deit='docker exec -it'
alias drri='docker run --rm -it'
alias drrie='docker run --rm -it --entrypoint=/bin/bash'

# docker-compose
alias dc='docker compose'
alias dcu='docker compose up'

1. dil

docker image ls

$ dil | head

REPOSITORY               TAG     IMAGE ID       CREATED             SIZE
andrewzah/personal_site  latest  be81beec6e75   58 minutes ago      191MB
<none>                   <none>  20996207d53a   About an hour ago   191MB
...

$ dil | grep -i personal_site
andrewzah/personal_site latest be81beec6e75  About an hour ago   191MB
andrewzah/personal_site <none> 5ab1ea639cf7  9 months ago        51.3MB

2. dps

docker ps

$ dps
CONTAINER ID   IMAGE                                    COMMAND                  CREATED         STATUS        PORTS                                                                                      NAMES

$ dps | grep -i gateway | cut -d' ' -f1
ae8e8dbc28dd

3. deit

docker exec -it

I frequently use this after dps to get into a running container.

$ deit ae8e8dbc28dd bash

4. drri and drrie

docker run --rm -it
docker run --rm -it --entrypoint=/bin/bash

I use this all the time for quickly spinning up and inspecting an image.

At AnalyticsHQ, most of our images have the entrypoint set to /init for the S6 supervisor. It’s handy to override that and enter with /bin/bash instead.

$ drri andrewzah/personal_site:latest
$ drrie docker.io/library/rockylinux:8.8.20230518-minimal

5. dc and dcu

These are self-explanatory but are highly useful with how often I manage services with docker compose.
