Access running docker container filesystem

问题

I am developing a WordPress theme and set up the development environment using docker. My docker-compose.yml volume property looks like this;

volumes:                                                                                                                
  - ~/WordPress/wp-content:/var/www/html/wp-content   

it mounts just the wp-content directory to the local machine. I now have to edit wp-config file which is in /var/www/html/ the docker image container. Can anyone here show me how to access and edit the wp-config file in the running docker container?

回答1:

You can run a shell terminal in the running container.

1. Get the container ID

    docker container ls
   

2. Run the terminal

    docker container exec -it container_ID "/bin/bash"
   

But, whatever change you do, it will not be persisted. You have to map this volume also.

 volumes:
      - ~/WordPress/wp-content:/var/www/html
