Mender is an open source over-the-air (OTA) software updater for embedded Linux devices. Mender comprises a client running at the embedded device, as well as a server that manages deployments across many devices.
This repository contains the Mender Device Authentication service, which is part of the Mender server. The Mender server is designed as a microservices architecture and comprises several repositories.
Device Authentication is responsible for issuing, maintaining and verifying JWT authentication tokens used by devices in Mender API calls. A token is issued as a result of a successful bootstrap request, whereby the device presents its vendor-specific identity attributes, and can be admitted in the the system by the administrator. Each subsequent device-specific API call is then internally routed to this service for token verification. At any time, the administrator can also revoke the JWT in case it was compromised.
To start using Mender, we recommend that you begin with the Getting started section in the Mender documentation.
As the Mender server is designed as microservices architecture, it requires several repositories to be built to be fully functional. If you are testing the Mender server it is therefore easier to follow the getting started section above as it integrates these services.
If you would like to build the Device Authentication service independently, you can follow these steps:
git clone https://github.com/mendersoftware/deviceauth.git
cd deviceauth
go build
The service can be configured by:
- providing configuration file (supports JSON, TOML, YAML and HCL formatting). The default configuration file is provided to be downloaded from config.yaml.
- setting environment variables. The service will check for a environment variable with a name matching the key uppercased and prefixed with "DEVICEAUTH_". Eg. for "listen" the variable name is "DEVICEAUTH_LISTEN".
