magmad service

magmad service is a core part of magma gateway platform, it is required on every gateway and facilitates the following gateway functionality:

• Maintaining and displaying unique gateway identity information necessary for the gateway register on and join a network
• Bootstraping gateway on the network and maintaining gateway's client certificates
• Checking in with the cloud and providing the cloud with up to date gateway status
• Monitoring gateway services, collecting and publishing the services' and system metrics to the cloud
• Creating and maintaining secure cloud to gateway RPC channel for real time cloud requests fulfilment
• Delivering and maintaining of cloud controlled gateway services' configuration
• Providing gateway control APIs to the cloud, such as:
  • starting/stopping gateway services
  • rebooting gateway
  • running network diagnostics
  • remote execution of permitted commands
  • etc.

Implementation

This is Go native implementation of magmad service, it is intended as a 'drop in' replacement of python based magmad service on systems with limited resources or lack of full python support. It'll work with all existing magmad.yml, service_registry.yml and control_proxy.yml configurations located in /etc/magma/configs or legacy /etc/magma directories.

Current implementation requires at least 15MB of RAM and 3MB of storage (compressed) on most supported systems/architectures.

Building magmad

magmad binary can be built on any system with installed Go tools. Go1.12 or later is recommended.

To build:

• Clone magma github repository
• (optional) Create a target directory for magmad binary (example: mkdir -p ~/bin/arm; mkdir -p ~/bin/amd64)
• cd magma/gateway/go
• Use Go tool to build magmad for your target platform. Examples:
  • GOOS=linux GOARCH=arm go build -o ~/bin/arm/ magma/gateway/services/magmad
  • GOOS=linux GOARCH=amd64 go build -o ~/bin/amd64/ magma/gateway/services/magmad
• To reduce magmad binary size, you may use the following options:
  • GOOS=linux GOARCH=arm go build -o ~/bin/arm/magmad.prod -ldflags="-s -w" magma/gateway/services/magmad
  • You can also use upx to compress the binary:
    • upx --brute -o ~/bin/arm/magmad ~/bin/arm/magmad.prod
