Basic Usage of HexDocker

Preparation (using hex_noetic_basic as an example)

   cd ~/hex_docker/docker_shell

   chmod +x start.sh

   ./start.sh

   

2. Use the following command to enter the container and start using it:

   docker attach hex_noetic_basic

   

Basic Operations

1. The usage of the container is essentially the same as normal command line usage.

2. If you want to run multiple programs, you can use tmux. Refer to the tutorial for usage instructions.

   

3. To suspend the current container, press Ctrl+p, then Ctrl+q.

   

   You can restore it with the following command:

   docker attach hex_noetic_basic

   

4. To exit the current container, simply type exit.

   

   After exiting, if you want to restart the container, you need to use the following command (at this point, the container is in a stopped state):

   docker start hex_noetic_basic
