docker-compose restart a service(docker-compose.yml changed)

In order to restart a service in docker-compose after you have changed the docker-compose.yml configuration, you will need to follow these steps:

1. Stop the running service:

   docker-compose stop <service_name>
   

   Replace <service_name> with the name of the service you want to restart as defined in your docker-compose.yml file.

2. Rebuild the service (if necessary):
   If you have made changes that affect the build configuration of the service (like changes to the Dockerfile or build context), you'll want to rebuild the service's image:

   docker-compose build <service_name>
   

   Again, replace <service_name> with the appropriate service name.

3. Start the service again:

   docker-compose up -d <service_name>
   

   This will start the service in a detached mode, using the updated configuration.

If you simply want to restart the service without stopping it first or if the changes do not require a rebuild (like environment variables, command, ports, etc.), you can use the following command to restart the service:

docker-compose up -d --no-deps --force-recreate <service_name>

The --no-deps flag tells Docker Compose not to start linked services, and --force-recreate will force the recreation of the container even if the configuration hasn't changed. This can be useful if the change is in the environment or in a mounted volume.

Remember that if you have made changes that affect the dependencies of the service or the service's image needs to be rebuilt, you should perform the stop, build, and up sequence to ensure that the changes take effect.
