devcontainer open-in-code
The devcontainer open-in-code command opens the current folder in VS Code as a dev container, i.e. it skips the normal step of opening in VS Code and then clicking # on the “Re-open in container” prompt to reload the window as a dev container. With devcontainer open-in-code you get straight to the dev container!
You can also use devcontainer open-in-code <path> to open a the devcontainer from a different folder.
The command also supports the --sub-folder option. This allows you to specify a sub-folder within the folder that contains the devcontainer configuration (i.e. with the .devcontainer folder or .devcontainer.json file).
The open-in-code command will walk up the tree from the current/specified folder until it finds a folder with a devcontainer configuration, and then open that folder in VS Code as a dev container.
If --sub-folder is not specified and the devcontainer configuration is found in a parent folder, relative path to the current folder is used as the sub-folder.
If you want to use the VS Code Insiders release, you can use devcontainer open-in-code-insiders.
