Warning: 'resin ssh' requires an openssh-compatible client 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 get a shell into the running application container of
|
|
your device.

|
|
|
$ resin ssh MyApp
|
|
$ resin ssh 7cf02a6
