Pausing and resuming in docker headless mode

[DrewThomasson]

Related, I found out one can pause a running docker image

• so you could probably launch the headless VoxNovel docker with the modifications done for this other project--->

Info about pausing and unpausing Docker image

Summary of Commands for Running and Pausing the Docker Image

---

Launching the Docker Image (You have to use these modified launch command instead if you want to pause or unpause it.)

Without GPU Support

docker run -it -p 7860:7860 athomasson2/ebook2audiobookxtts:latest

With GPU Support

docker run --gpus all -it -p 7860:7860 athomasson2/ebook2audiobookxtts:latest

Explanation:

• Removed --rm Flag: By omitting the --rm flag, the container won't be automatically removed when stopped or paused. This allows you to pause and unpause the container without losing its state or output.
• GPU Support: The --gpus all flag enables GPU acceleration if you have NVIDIA GPUs and the necessary drivers (nvidia-docker2 or Docker's native GPU support) installed.

Pausing and Unpausing the Docker Container

On Linux and macOS

• Pause Command:

  docker ps -q --filter "ancestor=athomasson2/ebook2audiobookxtts:latest" | xargs docker pause

• Unpause Command:

  docker ps -q --filter "ancestor=athomasson2/ebook2audiobookxtts:latest" | xargs docker unpause

On Windows (PowerShell)

• Pause Command:

  docker pause $(docker ps -q --filter "ancestor=athomasson2/ebook2audiobookxtts:latest")

• Unpause Command:

  docker unpause $(docker ps -q --filter "ancestor=athomasson2/ebook2audiobookxtts:latest")

Explanation:

• These commands locate the running container based on the image name athomasson2/ebook2audiobookxtts:latest and apply the pause or unpause action.
• For Linux and macOS:
  • Uses xargs to pass the container ID to docker pause or docker unpause.
• For Windows PowerShell:
  • Uses $() to execute the inner command and pass its output to docker pause or docker unpause.

Additional Notes:

• Monitoring the Terminal Output: Since we're using the -it flags (-i for interactive, -t for a pseudo-TTY), you'll continue to see the terminal output of the Docker container, which is useful for monitoring its activity.
• Preserving Container State: Pausing the container preserves its current state and data in memory. When you unpause it, the container resumes execution exactly where it left off.
