1. If this is your first time using a development container, please follow the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started).
2. **Linux users:** Update `USER_UID` and `USER_GID` in `.devcontainer/Dockerfile` with your user UID/GID if not 1000 to avoid creating files as root.
2. To use this repository, you can either open a locally cloned copy of the code:
3. If you're not yet in a development container:
- Clone this repository.
- Clone this repository to your local filesystem.
- Press <kbd>F1</kbd> 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 <kbd>F1</kbd> and select the **Remote-Containers: Try a Sample...** command.
- Choose the "Node" 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.
## Things to try
Once you have this sample opened in a container, you'll be able to work with it like you would locally.

Some things to try:
1. **Edit:**
- Open `app.py`
- Try adding some code and check out the language features.
2. **Terminal:** Press <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>\`</kbd> and type `uname` and or other Linux commands from the terminal window.
2. **Terminal:**
- Press <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>\`</kbd> to open a terminal window.
- Type `flask run --host 0.0.0.0 --port 9000 --no-debugger --no-reload` to run the app.
> **Note:** It is important to add `--host 0.0.0.0` when using `appPort` in `devcontainer.json` since this uses Docker to "publish" the port rather than forwarding it. It therefore will not work if the application only listens to localhost.
- Open a local browser and go to `http://localhost:9000` to see the running app.
3. **Build, Run, and Debug:**
- Open `app.py`
- Add a breakpoint (e.g. on line 9).
