Question 1

How do I install and set up docker.el in Emacs?

Accepted Answer

Install via MELPA using a package manager like use-package, as shown in the README. Bind a key to 'docker' for quick access, and customize variables such as docker-command if your setup differs from defaults.

Question 2

Is docker.el better than just using the Docker CLI in a terminal?

Accepted Answer

For Emacs users, docker.el offers integrated, keyboard-driven management that reduces context switching, but the CLI is more versatile for scripting and automation. Choose based on your workflow preferences.

Question 3

How can I manage docker-compose projects with docker.el?

Accepted Answer

Use the docker.el interface to execute common docker-compose commands like up, down, build, and logs directly from Emacs, making it convenient for local development without terminal hopping.

Question 4

Can docker.el handle Docker Swarm or Kubernetes?

Accepted Answer

No, docker.el does not support Docker Swarm or Kubernetes; it focuses on core Docker operations and docker-compose. For orchestration, you'll need to use other tools or the CLI.

Question 5

How to customize default arguments for docker run in docker.el?

Accepted Answer

Set 'docker-image-run-default-args' globally or use 'docker-image-run-custom-args' to match image patterns, such as adding environment variables for PostgreSQL, as demonstrated in the README examples.

Question 6

What if docker.el commands are slow or fail to work?

Accepted Answer

Enable 'docker-show-messages' to debug command outputs, ensure Docker is running and accessible, and adjust 'docker-terminal-backend' for performance, as shell buffers might lag with large outputs.
