How do i create a custom devcontainer?

Question

i have been using devcontainers for a while, and i want to extend some of them.
For instance, i want to install all the linting tools etc for various languages, and use a more personalised container as a starting point (compared to the Microsoft hosted ones).

I also like to host the containers on my own dockerhub, so i do not need to build all this stuff every time. There could also be the use case of using devcontainers for something other than the standard libraries.

I know i can just manually change the docker image reference, but i also like to integrate my changes into the plugin, so i can have my own repository show up as well, to get a native feeling.

I could not find any information on creating my own dev containers, only on extending existing ones. Is any of this i mention officially supported?

Edit: To sum all this up in one question; Can i add devcontainers from my own repo, without merging them into https://github.com/microsoft/vscode-dev-containers ?

If you are using VSCode as the text editor you can install the remote extension pack which allows you to add a template for a devcontainer to your project.

If you aren't using VSCode you can use the templated version as the basis for your own. I created a template repository with the files needed for Python project which you can refer to as well
