AutoDock

AutoDock is a containerized service to enable hzn cli to run in a container and interact with Open Horizon Agent which also runs in its own container. AutoDock also comes pre-installed with npm hzn-cli package and an express server, this will allow for more granular controls on the edge device.

To setup Edge Node Agent, and to run CLI & agent in containers

  • Run curl -sSL https://raw.githubusercontent.com/playground/hzn-cli/main/install.sh --output install.sh && bash ./install.sh

    • 1) Cli-And-Anax	      4) Anax-In-Container  7) Confirm
2) CLI-Only	          5) Run-In-Containers  8) Quit
3) CLI-In-Container   6) All-In-One
Choose your environment setup: 5

Run-In-Containers, Runs both CLI and Agent in its own container, choose <Confirm> to continue setup.

Choose your environment setup: 7
You have chosen Run-In-Containers
1) Config-File
2) Confirm
3) Help
4) Quit
Continue with setup: 1

Please provide absolute path to configuration file, then choose <Confirm> to continue setup.

  • horizon file should have the following env vars
HZN_EXCHANGE_URL=
HZN_FSS_CSSURL=
HZN_DEVICE_ID=
HZN_NODE_ID=
HZN_AGBOT_URL=
HZN_SDO_SVC_URL=
HZN_MGMT_HUB_CERT_PATH=

  • With the above configuration, the edge node will be setup with horizon1 and auto-dock containers and agent is registered with the policy. The services with the constraints that match this policy properties will get loaded. In this case, mms-agent and homehub-express services will be loaded as described in the configuration.

  • Docker ps will show

  • mms-agent

    mms-agent is a containerized service that checks for updates coming from MMS this edge node cares about. mms-agent will deliver updates to the shared volume for services to consume and process accordingly.
