Containerizing a simple fastapi Python app.

Colima is an open-source project, offering transparency and community contributions. It provides more customization options for the virtual machine environment and has no licensing restrictions unlike Docker Desktop. Additionally, Colima supports different container runtimes like Docker and Containerd, giving us the flexibility to choose the best tool for our needs.

To use Colima for container runtime on macOS, install it using Homebrew:

brew install colima

Start Colima with:

colima start

For a detached session:

colima start -d

Check the status of Colima:

colima status

Stop Colima when you’re done:

colima stop

For more detailed usage and options, please look to the Colima documentation.

docker compose up --build

You can run the application detached from the terminal by adding the -d option

docker compose up --build -d

docker compose down
