A Brief Intro
Have you ever feel that you have too much docker container from spin up a
bunch of docker-compose.yaml file? And when you want to take down all those
docker container from the docker-compose.yml, you already delete the file?
If that’s the case, then this post might be for you.
Before we start, we will be using docker compose version 2.16.0 in this post. If you are using the older version of docker compose, then this method might not work. Please keep that in mind.
Check Docker Compose Project Name
The first thing we need to do is to check the project name. We can do that with command:
docker-compose ls
or if we use docker compose v2, we can use this command instead:
docker compose ls
If the container already stopped, we can use flags -a or --all like this:
docker-compose ls -a
or this:
docker compose ls -a
By default, docker compose will use the docker-compose.yml directory name as
project name. We can specify the project name with flag -p or
--project-name like this:
docker-compose -p anu up -d
or this:
docker compose -p anu up -d
Please keep in mind that we need to use the flags -p or --project-name
before the command such as up or down.
Take Down Docker Compose Component
After we know the project name, we can take down all docker component when we
spin up the docker container from docker-compose.yml. The component in here
means volume, network, or anything that we define inside docker-compose.yml.
To take down component from docker compose without the docker-compose.yml,
we can use this command:
docker-compose -p project-name down <docker-compose-down-flags>
or this:
docker compose -p project-name down <docker-compose-down-flags>
For example, let’s say we want to take down docker component from project anu and also remove the volume from those project. We can do that with this command:
docker-compose -p anu down -v
or this:
docker compose -p anu down -v
Alright, that’s it!
I am not sure since when the ls command appear in docker compose, so just
to be safe i recommend using at least docker compose version 2.16.0.
Side Note
I’ve tried this method with docker compose version 1.18.0, but failed. After i downloaded the docker compose binary version 2.16.0 from github, i can use this method.
Still not sure what was wrong. When i use command docker-compose --help, the
flag -p in there. But when i actually spin up a new docker instance with
command:
docker-compose -p project-name up -d service-name
and then tried to take it down with command:
docker-compose -p project-name down -v
i got an error docker-compose.yml not found or along those lines.
If someone know what’s going on, please let me know!
