Connecting to container's console

Docker containers can be accessed by attaching to their terminals. To execute this task, you can use the command:

$docker exec -it <hostName> /bin/bash

This command will work with all the images provided in the current version of the P4D-GUI, including the switches. Just use the name of the container that you want to connect, and then you can execute any command.

If you wish to copy any files to the container, like your own scripts, you can do this by two methods:

1) Using the "Shared" volume: The shared volume is connected to all containers created using the P4D-GUI script. You can just copy any file to this volume, and it should be accessible inside the containers at the path "/codes" . To copy files to the volume, you can use the volume path in your system. The default path is:

/var/lib/docker/volumes/shared/_data/

Any file copied in this directory will appear and be accessible inside the container at the "/codes" directory.

In this example, the script "myscript.sh" is located in the "Downloads" directory and copied to the /var/lib/docker/volumes/shared/_data/ directory.

After that step, we connect to the container with:

$docker exec -it host1 /bin/bash

and a "ls" command shows that the "myscript.sh" is already available inside the container. The following step gives execution permission to the file and executes it.

This script is being executed inside container host1 and will not affect or be visible by any other container since each environment is isolated.

2) Using docker CP command:

To copy a specific file to a docker container, you can also use the "docker cp". First, locate the file that you want to copy inside the container and execute the command as follows:

$docker cp myfile host1:/path/myfile Using the same example as the file "myscript.sh" described on the previous topic, you could use:

$ docker cp myscript.sh host1:/codes/myscript.sh

The file will now be available inside the container. Using this method, you can copy to directories other than "/code", since you are not using volumes. Just make sure to remember the path you chose.
