Convert a docker run command into a docker-compose

Question

I want to run this in my Docker Swarm:

docker run --rm -it progrium/stress --cpu 2 --io 1 --vm 2 --vm-bytes 128M --timeout 10s

so I need a Docker-compose.yml

How should I use this docker image in a docker compose and pass those params ?

Have you read through the [docker-compose documentation](https://docs.docker.com/compose/)? — larsks, Apr 23 '18 at 15:59

Converting a docker run command into a compose file

Composerize will help you convert run command to a compose partially.

To understand it better I have described the components of the docker-compose.yml here.

image - image used to run the container

name - name of the service or container

command - command you want to run after the container is up

volumes - volume(s) you want to mount

Converting the run command from above to docker-compose:

version: "2/3/3.3/3.6" # based on the docker-compose version you use
services:
   stress: # Service name, user defined
      image: progrium/stress 
      command: '--cpu 2 --io 1 --vm 2 --vm-bytes 128M --timeout 10s'

First two lines are common for any docker-compose file.

In docker-compose, the command allows the image to accept additional commands or options.

docker-compose.yml

version: "2"
services:
   stress:
      image: progrium/stress
      command: '--cpu 2 --io 1 --vm 2 --vm-bytes 128M --timeout 10s'

Compose the file with docker-compose as:

docker-compose up -d

Multiple commands to the compose file:

command: bash -c "cd app/ && npm start"

Multi-line command to compose file:

command: >
  bash -c "cd app/ 
  && npm start"

I am looking for a tool that does the opposite - creates docker run commands from a docker compose file. Is there one? — Oleg Abrazhaev, Jul 06 '22 at 14:27

Just use this nifty little tool as a helper: https://composerize.com/

Or follow the manual steps highlighted in the previous answers...

This tool is nice but is very limited for some docker run commands. – Lord_Dracon May 13 '19 at 19:11
BTW, it runs from CLI too: https://github.com/magicmark/composerize#cli – saulius2 May 24 '22 at 19:56

You can use Compose file's command or entrypoint keyword. It is straightforward to translate a docker run command into declarations in the docker-compose.yml file.

To use the command keyword in your docker-compose.yml:

services:
  stress:
    image: progrium/stress
    command:
    - --cpu 2
    - --io 1
    - --vm 2
    - --vm-bytes 128M
    - --timeout 10s

To use the entrypoint keyword in your docker-compose.yml:

services:
  stress:
    image: progrium/stress
    entrypoint:
    - <entrypoint name to override the original one>
    - --cpu 2
    - --io 1
    - --vm 2
    - --vm-bytes 128M
    - --timeout 10s
