description: '(beta) sync your changes to a device'
help: '''
Warning: 'resin sync' 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/resin-io/resin-cli
Use this command to sync your local changes to a certain device on the fly.
After every 'resin sync' the updated settings will be saved in
'<source>/.resin-sync.yml' and will be used in later invocations. You can
also change any option by editing '.resin-sync.yml' directly.
Here is an example '.resin-sync.yml' :
$ cat $PWD/.resin-sync.yml
uuid: 7cf02a6
destination: '/usr/src/app'
before: 'echo Hello'
after: 'echo Done'
ignore:
- .git
- node_modules/
Command line options have precedence over the ones saved in '.resin-sync.yml'.
If '.gitignore' is found in the source directory then all explicitly listed files will be
excluded from the syncing process. You can choose to change this default behavior with the
'--skip-gitignore' option.
Examples:
$ resin sync 7cf02a6 --source . --destination /usr/src/app
$ resin sync 7cf02a6 -s /home/user/myResinProject -d /usr/src/app --before 'echo Hello' --after 'echo Done'
$ resin sync --ignore lib/
$ resin sync --verbose false
$ resin sync
