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"
