Compose stack for silverline services

Creates several containers with Silverline services:

• Orchestrator
• Demo Runtime [TODO]
• Web server for dashboard (Nginx)
• Database (influxdb)
• Metrics Agent (telegraf)
• Plots (Graphana)

The dashboard is a submodule of this repo. Orchestrator and runtime are started from pre-built images. The nginx container serves the dashboard files and acts as proxy.

Quick Setup

1. We need docker and docker-compose.

2. Clone this repo (with --recurse-submodules to make sure you get the contents of the repositories added as submodules):

git clone https://github.com/arenaxr/silverline-services-docker.git --recurse-submodules

3. Modify configuration:

• Copy the example configuration env.default to .env

cp env.default .env

If you have a arena-services-docker setup on the same machine, you can skip the MQTT section and execute init-env-from-arena-services.sh to fetch this configuration from arena-services-docker

• Edit MQTT_SERVER, MQTT_SERVER_PORT, MQTT_WEBHOST, MQTT_WEBHOST_PATH, MQTT_TOPIC, MQTT_USER, MQTT_PWD,DASHBOARD_ORCHESTRATOR_API_HOST and DASHBOARD_ORCHESTRATOR_API_PORT in .env. This should reflect your setup.

...

# MQTT
# mqtt broker; e.g.: arena-dev1.conix.io (compose-from-arena-services.sh will get this config from arena-services-docker)
MQTT_SERVER=broker-host
# mqtt broker port; e.g.: 8883 (compose-from-arena-services.sh will get this config from arena-services-docker)
MQTT_SERVER_PORT=broker-port
# mqtt broker host for websocket connections; e.g.: arena-dev1.conix.io (compose-from-arena-services.sh will get this config from arena-services-docker)
MQTT_WEBHOST=broker-web-host 
# mqtt broker endpoint for websocket connections; 'mqtt' is usually a safe default
MQTT_WEBHOST_PATH=mqtt
# keepalive topic; this is usually a safe default
MQTT_TOPIC=realm/proc/keepalive/# 
# mqtt username; e.g.: cli (compose-from-arena-services.sh will get this config from arena-services-docker)
MQTT_USER=auser
# mqtt password; e.g.: a very long JWT: eyJ0eXAiOiJKV1QiLCJhbGc...  (compose-from-arena-services.sh will get this config from arena-services-docker)
MQTT_PWD=apasswd

# Dashboard 
# port exposed for the dashboard; e.g. 8001
DASHBOARD_PORT=dashboard-port
# host of the orchestrator where REST calls are available; e.g. arena-dev1.conix.io
DASHBOARD_ORCHESTRATOR_API_HOST=orchestrator-host
# orchestrator api port; e.g. 8000
DASHBOARD_ORCHESTRATOR_API_PORT=orchestrator-port
...

Optionally, for a more secure setup, you can change the DOCKER_INFLUXDB_INIT_PASSWORD and DOCKER_INFLUXDB_INIT_ADMIN_TOKEN. They can be any random secret string.

4. You should be good to start all services in background (-d) using docker-compose:

 docker-compose up -d

Update dashboard

To update with the lastest source:

git pull --recurse-submodules
git submodule update
docker-compose up -d --no-deps --build dashboard
