Dockerizing an application
Containers are made up of images. Images contain your project and it's dependencies.
Add a Dockerfile to the start project. The Dockerfile should do the following...
Include a base Node image
Copy all the project files into the image
Run an npm install
Expose port 3000
Run npm start
Build the image
Open the Command Palette (Cmd/Ctrl + Shift + P)
Select "Add Dockefiles to workspace"
Select the "start" project
Select "Node.js" from the prompt
Enter "3000" in the prompt
VS Code will add "Dockerfile", "docker-compose.yml" and "debug.docker-compose.yml" files to the project
Open the "Dockerfile" in the "start" project
Add two ENV variables, "API_BASE" and "PORT"
Open the Command Palette (Cmd/Ctrl + Shift + P)
Select "Docker Images: Build Image"
Select "start" as the workspace folder
Take the default image tag
An integrated terminal instance will open and Docker will build the image
Note that if you get an error saying "cannot connect to Docker daemon", make sure that Docker is installed and running on your machine.
