NervesHubCLI

Important

This is the 2.0 development branch of NervesHubCLI. If you have been using NervesHub prior to around April, 2023 and are not following 2.0 development, see the maint-v0 branch. The maint-v0 branch is being used in production. 2.0 development is in progress, and we don't have guides or good documentation yet. If you use the 2.0 development branch, we don't expect breaking changes, but please bear with us as we complete the 2.0 release.

NervesHubCLI provides a set of Mix tasks so that you can work with NervesHub from the command-line. Features include:

• Uploading firmware to NervesHub
• Generating device certificates and registration
• Managing device provisioning metadata
• Creating and managing firmware signing keys
• Manage firmware deployments
• Manage user and organization accounts

The recommended way of using the CLI is to include nerves_hub_link in your dependencies. nerves_hub_link pulls in nerves_hub_cli and includes the target runtime components necessary to use it.

Once installed, you can access available commands and documentation from the command-line using mix help:

$ mix help
...
mix nerves_hub.deployment # Manages NervesHub deployments
mix nerves_hub.device     # Manages your NervesHub devices
mix nerves_hub.firmware   # Manages firmware on NervesHub
mix nerves_hub.key        # Manages your firmware signing keys
mix nerves_hub.product    # Manages your products
mix nerves_hub.user       # Manages your NervesHub user account
...

$ mix help nerves_hub.device
...
