How to restart a single container with docker-compose

Question

I have a docker-compose.yml file that contains 4 containers: redis, postgres, api, worker

During the development of worker, I often need to restart it i

Answer 1

Following command

docker-compose restart worker

will just STOP and START the container. i.e without loading any changes from the docker-compose.xml

STOP is similar to hibernating in PC . Hence stop/start will not look for any changes made in configuration file . To reload from the recipe of container (docker-compose.xml) we need to remove and create the container (Similar analogy to rebooting the PC )

So commands will be as following

docker-compose stop worker       // go to hibernate
docker-compose rm worker        // shutdown the PC 
docker-compose create worker     // create the container from image and put it in hibernate

docker-compose start worker //bring container to life from hibernation

Answer 2

The answer's here are talking about the reflection of the change on the docker-compose.yml file.

But what if I want to incorporate the changes I have done in my code, and I believe that will be only possible by rebuilding the image and that I do with following commands

1. docker container stop

docker stop container-id

2. docker container removal

docker rm container-id

3. docker image removal

docker rmi image-id

4. compose the container again

docker-compose up container-name

Answer 3

Simple 'docker' command knows nothing about 'worker' container. Use command like this

docker-compose -f docker-compose.yml restart worker
