VSCode and Docker
VSCode has some really useful features for working with Docker Objects
Our project has been configured with an awareness of our docker configurations
Start a Stack
The top button in the ribbon on the left is called “Explorer”. Click that button.
- Navigate to examples/session2/docker-compose.yml
- Right click the file
- Click “Compose Up”
- Click “simpsons stack” in the popup window
Notice that the output from the docker-compose up command appears in a terminal panel.
If any errors occur, there may be resources active from the Session 2 exercises. We’ll discover those in VSCode!
