8.3. Setting up Podman on macOS

Procedure

1. Create the Podman machine:

   $ podman machine init --memory=8192 --cpus=2 --disk-size=20

2. Start the Podman machine, which serves the Docker API on a UNIX socket:

   $ podman machine start
   Starting machine "podman-machine-default"
   Waiting for VM ...
   Mounting volume... /Users/myuser:/Users/user
   
   [...truncated output...]
   
   You can still connect Docker API clients by setting DOCKER_HOST using the
   following command in your terminal session:
   
   	export DOCKER_HOST='unix:///Users/myuser/.local/share/containers/podman/machine/podman-machine-default/podman.sock'
   
   Machine "podman-machine-default" started successfully

   注意

   On most macOS systems, this socket is located at /Users/myuser/.local/share/containers/podman/machine/podman-machine-default/podman.sock.

3. Establish the environment variable that is used to build a function:

   $ export DOCKER_HOST='unix:///Users/myuser/.local/share/containers/podman/machine/podman-machine-default/podman.sock'

4. Run the build command inside your function project directory with the -v flag to see verbose output. You should see a connection to your local UNIX socket:

   $ kn func build -v
