Custom Installation

The CLI is a compiled binary that can be downloaded from the releases page.

Once downloaded you can run the binary directly, although we recommend adding it to your PATH so that it's accessible across terminal sessions.

You can access available commands and documentation from the command-line using nh help. eg.

$ nh help
$ nh help device

Connecting to your NervesHub

When using the CLI, the default URI points to NervesCloud : https://manage.nervescloud.com.

To configure a different URI you can use:

$ nh config set uri "https://my.selfhosted.instance/"

Finally, you need to authorize your account with the choosen platform by running:

$ nh user auth

Environment variables

The CLI can be configured using environment variables to simplify automation.

The following variables are available:

• NERVES_CLOUD_TOKEN/NERVES_HUB_TOKEN - Token used to authenticate API requests
• NERVES_CLOUD_ORG/NERVES_HUB_ORG - Organization used for API requests
• NERVES_CLOUD_PRODUCT/NERVES_HUB_PRODUCT - Product to used for API requests
• NERVES_CLOUD_FW_PRIVATE_KEY/NERVES_HUB_FW_PRIVATE_KEY - Private key used for signing firmware
• NERVES_CLOUD_FW_PUBLIC_KEY/NERVES_HUB_FW_PUBLIC_KEY - Public key used for verifying firmware
• NERVES_CLOUD_DATA_DIR/NERVES_HUB_DATA_DIR - Directory used for storing config and signing keys (defaults to ~/.nerves-cloud/~/.nerves-hub)
• NERVES_CLOUD_URI/NERVES_HUB_URI - Platform URI (defaults to https://manage.nervescloud.com)
• NERVES_CLOUD_NON_INTERACTIVE/NERVES_HUB_NON_INTERACTIVE - Force all yes/no user interaction to be yes

Uninstalling the CLI

$ nh maintenance uninstall

Once you have run the above command you can safely delete the nh binary.
