The command Dev Containers: Rebuild Container and Reopen in Container doesn't exist

I’m completly new in Docker. I try this tutorial : Relational Database Course – How to Learn SQL in VSCode Using Docker and freeCodeCamp but the 3 step doesn’t work.

Does anyone had the same issue?

Installing the Dev Containers extension is a Prerequisites as it is in the linked post:


Before you get started, you need to have a few things installed:

  1. The Docker Engine
  2. VS Code
  3. The Dev Containers extension for VS Code
  4. Git

and you typed Dev Container not Dev Containers with the “s” at the end.
