Question 1

How to install custom Zsh themes in Docker with Zsh-in-Docker?

Accepted Answer

Use the -t flag with a Git URL in the RUN command, like '-t https://github.com/denysdovhan/spaceship-prompt'. The script clones and configures it, as shown in the README example with Spaceship.

Question 2

Zsh-in-Docker or manual Oh My Zsh installation in Dockerfile?

Accepted Answer

Zsh-in-Docker is faster for standard setups with one-liner convenience, but manual installation offers more control over dependencies and steps for optimized or secure builds.

Question 3

Can Zsh-in-Docker work with Alpine Linux without extra dependencies?

Accepted Answer

Yes, it supports Alpine, but you may need to ensure git and curl are installed first or use the -x flag. Alpine's minimal nature might require additional package management steps.

Question 4

How to skip installing git and curl with Zsh-in-Docker?

Accepted Answer

Add the -x flag to the command, as noted in the README. Pre-install these dependencies in your Dockerfile to avoid permission issues, especially with non-root users.

Question 5

Is Zsh-in-Docker secure for CI/CD pipelines?

Accepted Answer

It relies on downloading an external script, which can be a risk. Consider pinning to a specific version or auditing the script, and use in trusted networks only.

Question 6

What themes come bundled with Zsh-in-Docker?

Accepted Answer

It includes Oh My Zsh bundled themes like robbyrussell, and defaults to powerlevel10k. Custom themes require Git URLs, as detailed in the -t option examples.
