Code Server Customizations

About

The Arkanum image itself depends on the underlying coder/code-server project and the container image provided by linxuserver/docker-code-server. To be able to add features and change the behaviour we need to customize either the code-server itself of the docker image creation.

These are the custimzations we added to build the arkanum server and the arkanum-cli :

Bash Aliases

You can use the alias summon to interact with the code-server instance.

Product Images

We replaces the product image files to math the arkanum branding. See the code-server/media folder for the used files.

Application Name

The code-server command provides the ability to change it's name in the title other places. We also use arkanum therefore.
