Welcome to Adam! Adam is the reference implementation of an LF-Edge API-compliant Controller. You can use Adam to drive one or more EVE instances from any computer, locally, in the cloud, or in a container.

Adam is a reference implementation. Thus, while it has all of the TLS encryption and authentication requirements of the official API, it has not been built or tested to withstand penetration attacks, DDoS, or any other major security requirements, and it has not been built with massive scale in mind. For those, please refer to various vendor cloud controller offerings, such as Zededa zedcloud.

Running Adam

To run Adam, you need a built Adam binary. Adam distributes both as a single binary available on all major platforms - Linux, macOS, Windows - as well as an OCI compliant container image.

The adam command has multiple options. The primary one is:

adam server

which will run Adam, listening on the default port of 8080 (it will tell you which when it starts), using the default server TLS key and certificate, using ./run/adam/ as its file storage location. These options are modifiable via the command-line; run adam server --help for options.

If you prefer to run Adam as a docker container:

docker run lfedge/adam server

You can add any of the options that would exist with a local Adam installation, including help: docker run lfedge/adam server --help.

Note that when running in a docker container, directories are ephemeral. If you want to keep the directories, you should bind-mount them into your container.

docker run -v $PWD/run:/somedir/run lfedge/adam server --conf-dir /somedir/run/config --db-url /somedir/run/adam --server-cert /somedir/run/adam/server.pem --server-key /somedir/run/server-key.pem

The default working directory for adam in the container is /adam/, which means the following will just work:

docker run -v $PWD/run:/adam/run lfedge/adam server

Or, you can use volume containers.

To make things easier, this repository includes a sample docker-compose.yml which runs adam, maps port 8080 in the container to 8080 on your host, and mounts the current directory's ./run/adam/ to the default /adam/run/adam/ in the container.

Finally, remember to map your ports when using a docker container:

docker run -v $PWD/run:/adam/run -p 8080:8080 lfedge/adam server

By default, adam listens on port 8080, but can be configured. Run adam server --help.

Building Adam

Building Adam is straightforward:

  1. Clone this repo
  2. Ensure you have installed either go >= 1.11, or docker
  3. Run make build-docker to build in docker (or just make build or even make), or make build-local to build using a local installation of go

This will build adam for your local operating system and architecture.

All Makefile commands have the option to run locally or in docker. By default, they run in docker. If you prefer to run using a locally installed go, pass BUILD=local to any command, e.g.

make vet BUILD=local

Server TLS

Adam requires TLS to communicate with EVE devices, which means a server key and certificate. If one is not available, it will fail startup. You can generate one using:

adam generate server

Run adam generate server --help for options. By default, it stores the server key and certificate in the same location as the default when running adam server.

Registering Devices

For an EVE device to be accepted into Adam, it needs to be listed as one of:

  • acceptable to onboard
  • registered

An EVE device has to know the following before it can communicate with any controller (including Adam):

  • controller's host name and port #
  • controller's root certificate

additionally you may need to supply an entry mapping controller's host name to a routable IP address (in the /etc/hosts format)

When Adam server runs, it outputs all the required configuration in a folder specified by the conf-dir option (run/adam/config by default)


Onboarding is the process of enabling a device to self-register. This requires two pieces: an onboarding certificate, and a unique serial string. Each self-registering device must have a unique combination of onboarding certificate and serial string.

Adam has an onboarding directory where it maintains acceptable onboarding certificates and serials. By default, these are under ./run/adam/onboard/<cn>/, where the name cn is a file-friendly conversion of the certificate's Common Name. This directory contains two files:

  • cert.pem - the actual onboarding certificate.
  • serials.txt - a list of acceptable serials to use with this certificate, one per line. The wildcard * means any serial will be accepted.

You can modify these files directly; it is not, however, recommended.

Instead, use Adam's command-line admin options to work with the files:

adam generate

will generate a key/certificate pair, with a Common Name that you provide. Run adam generate --help for options.

You then can interact with the Adam server using adam admin:

$ adam admin device
$ adam admin onboard

These will list, add, remove, get or clear onboarding certificates and their serials, as well as devices directly.

Once you have generated an onboarding certificate, copy the certificate and key to the device to onboard.
