This is a sample project that lets you try out the VS Code Remote - Containers extension in a few easy steps.
Note: If you're following the quick start, you can jump to the Things to try section.
Follow these steps to open this sample in a container:
-
If this is your first time using a development container, please follow the getting started steps.
-
To use this repository, you can either open a locally cloned copy of the code:
- Clone this repository to your local filesystem.
- Press F1 and select the Remote-Containers: Open Folder in Container... command.
- Select the cloned copy of this folder, wait for the container to start, and try things out!
Or open the repository in an isolated Docker volume:
- Press F1 and select the Remote-Containers: Try a Sample... command.
- Choose the "Go" sample, wait for the container to start and try things out!
Note: Under the hood, this will use Remote-Containers: Open Repository in Container... command to clone the source code in a Docker volume instead of the local filesystem.
Once you have this sample opened in a container, you'll be able to work with it like you would locally.
Note: This container runs as a non-root user with sudo access by default. Comment out
"remoteUser": "vscode"
in.devcontainer/devcontainer.json
if you'd prefer to run as root.
