Using this definition

This definition creates two containers, one for Rust and one for PostgreSQL. VS Code will attach to the Rust dev container, and from within that container the PostgreSQL container will be available on localhost port 5432. The .env file sets the default credentials. The default database is named postgres with a user of postgres whose password is postgres, and if desired this may be changed in docker-compose.yml. Data is stored in a volume named postgres-data.

While the definition itself works unmodified, you can select the version of Debian the container uses by updating the VARIANT arg in .devcontainer/docker-compose.yml (and rebuilding if you've already created the container).

build:
      context: .
      dockerfile: Dockerfile
      args:
        # Use the VARIANT arg to pick a Debian OS version: buster, bullseye
        # Use bullseye when on local on arm64/Apple Silicon.
        VARIANT: buster

Adding the definition to a project or codespace

1. If this is your first time using a development container, please see getting started information on setting up Remote-Containers or creating a codespace using GitHub Codespaces.

2. Start VS Code and open your project folder or connect to a codespace.

3. Press F1 select and Add Development Container Configuration Files... command for Remote-Containers or Codespaces.

   Note: If needed, you can drag-and-drop the .devcontainer folder from this sub-folder in a locally cloned copy of this repository into the VS Code file explorer instead of using the command.

4. Select this definition. You may also need to select Show All Definitions... for it to appear.

5. Finally, press F1 and run Remote-Containers: Reopen Folder in Container or Codespaces: Rebuild Container to start using the definition.

Adding another service

You can add other services to your docker-compose.yml file as described in Docker's documentation. However, if you want anything running in this service to be available in the container on localhost, or want to forward the service locally, be sure to add this line to the service config:

# Runs the service on the same network as the database container, allows "forwardPorts" in devcontainer.json function.
network_mode: service:[$SERVICENAME]

Testing the definition

This definition includes some test code that will help you verify it is working as expected on your system. Follow these steps:

1. If this is your first time using a development container, please follow the getting started steps to set up your machine.
2. Clone this repository.
3. Start VS Code, press F1, and select Remote-Containers: Open Folder in Container...
4. Select the containers/rust-postgres folder.
5. After the folder has opened in the container, press F5 to start the project.
6. You should see "Hello, VS Code Remote - Containers!" in the Debug Console after the program executes.
7. You can also run test.sh in order to build and test the project.
8. From here, you can add breakpoints or edit the contents of the test-project folder to do further testing.
