[How to stop and restart Docker]

docker-compose up

Cannot start service database: driver failed programming external connectivity on endpoint 

This is a method to check and stop Docker that is currently running, which can be used when an error occurs.

① Check the current status of Docker

docker ps

To check the currently running Docker.

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
4db7e2473829        mysql:latest        "docker-entrypoint.s…"   8 days ago          Up 8 days           0.0.0.0:3306->3306/tcp, 33060/tcp   hello_world_database_1

It will be displayed like this. (It's hard to see, so it's better to widen the window to fill the screen.)

Confirm CONTAINER ID and copy (In the above, copy 4db7e2473829.)

② Stop Docker

docker stop 'CONTAINER ID'

To execute. 'CONTAINER ID' will be the value you copied earlier.

This time

docker stop 4db7e2473829

It will be.

③ Check Docker again (whether the specified Docker can be stopped)

again

docker ps

To execute.

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

When all Docker is stopped, the above display (no value is entered) is displayed. If there is a Doker running other than the Docker stopped in (2), the value other than the stopped Docker will be displayed.

④ Start Docker

Once the above work is done, as usual

docker-compose up

Let's run. You should be able to run it without errors.
