Manage Firmware on NervesHub
## publish
Upload signed firmware to NervesHub. Supplying a path to the firmware file
is optional. If it is not specified, NervesHub will locate the firmware
based off the project settings.
mix nerves_hub.firmware publish [Optional: /path/to/app.firmware]
### Command-line options
* `--product` - (Optional) The product name to publish the firmware to.
This defaults to the Mix Project config `:app` name.
* `--deploy` - (Optional) The name of a deployment to update following
firmware publish. This key can be passed multiple times to update
multiple deployments.
* `--key` - (Optional) The firmware signing key to sign the firmware with.
* `--ttl` - (Optional) The firmware max time to live seconds.
## list
mix nerves_hub.firmware list
### Command-line options
* `--product` - (Optional) The product name to publish the firmware to.
This defaults to the Mix Project config `:app` name.
## delete
Firmware can only be deleted if it is not associated to any deployment.
Call `list` to retrieve firmware UUIDs
mix nerves_hub.firmware delete [firmware_uuid]
## sign
Sign the local firmware. Supplying a path to the firmware file
is optional. If it is not specified, NervesHub will locate the firmware
based off the project settings.
mix nerves_hub.firmware sign [Optional: /path/to/app.firmware]
### Command-line options
* `--key` - (Optional) The firmware signing key to sign the firmware with.
