Snap ``commands`` is a dictionary or list of individual snap commands to run on the target system. These commands can be used to create snap users, install snaps and provide snap configuration. .. note:: If 'side-loading' private/unpublished snaps on an instance, it is best to create a snap seed directory and seed.yaml manifest in **/var/lib/snapd/seed/** which snapd automatically installs on startup. ax snap: assertions: 00: | signed_assertion_blob_here 02: | signed_assertion_blob_here commands: 00: snap create-user --sudoer --known @mydomain.com 01: snap install canonical-livepatch 02: canonical-livepatch enable ay # Convenience: the snap command can be omitted when specifying commands # as a list and 'snap' will automatically be prepended. # The following commands are equivalent: snap: commands: 00: ['install', 'vlc'] 01: ['snap', 'install', 'vlc'] 02: snap install vlc 03: 'snap install vlc' z # You can use a list of commands snap: commands: - ['install', 'vlc'] - ['snap', 'install', 'vlc'] - snap install vlc - 'snap install vlc' z # You can use a list of assertions snap: assertions: - signed_assertion_blob_here - | signed_assertion_blob_here snap)idnametitle descriptiondistrosZexamples frequencyZactivate_by_schema_keyscCs|sdStjdt|tr&|j}nt|ts@tdj|dtd|g}dj |}x&|D]}tjd|j ddd qZWt j ||j d tj|d d dS) aImport list of assertions. Import assertions by concatenating each assertion into a string separated by a ' '. Write this string to a instance file and then invoke `snap ack /path/to/file` and check for errors.
