	Warning: 'balena local push' requires an openssh-compatible client and 'rsync' to
	be correctly installed in your shell environment. For more information (including
	Windows support) please check the README here: https://github.com/balena-io/balena-cli

	Use this command to push your local changes to a container on a LAN-accessible balenaOS device on the fly.

	If `Dockerfile` or any file in the 'build-triggers' list is changed,
	a new container will be built and run on your device.
	If not, changes will simply be synced with `rsync` into the application container.

	After every 'balena local push' the updated settings will be saved in
	'<source>/.balena-sync.yml' and will be used in later invocations. You can
	also change any option by editing '.balena-sync.yml' directly.

	Here is an example '.balena-sync.yml' :

		$ cat $PWD/.balena-sync.yml
		local_balenaos:
			app-name: local-app
			build-triggers:
				- Dockerfile: file-hash-abcdefabcdefabcdefabcdefabcdefabcdef
				- package.json: file-hash-abcdefabcdefabcdefabcdefabcdefabcdef
			environment:
				- MY_VARIABLE=123


	Command line options have precedence over the ones saved in '.balena-sync.yml'.

	If '.gitignore' is found in the source directory then all explicitly listed files will be
	excluded when using rsync to update the container. You can choose to change this default behavior with the
	'--skip-gitignore' option.

	Examples:

		$ balena local push
		$ balena local push --app-name test-server --build-triggers package.json,requirements.txt
		$ balena local push --force-build
		$ balena local push --force-build --skip-logs
		$ balena local push --ignore lib/
		$ balena local push --verbose false
		$ balena local push 192.168.2.10 --source . --destination /usr/src/app
		$ balena local push 192.168.2.10 -s /home/user/balenaProject -d /usr/src/app --before 'echo Hello' --after 'echo Done'
