`buildx` comes bundled with Docker CE starting with 19.03, but requires experimental mode to be enabled on the Docker CLI.
To enable it, `"experimental": "enabled"` can be added to the CLI configuration file `~/.docker/config.json`. An alternative is to set the `DOCKER_CLI_EXPERIMENTAL=enabled` environment variable.
`buildx` comes bundled with Docker Desktop and in latest Docker CE packages.
