spate Demo

This example producer-consumer application demonstrates the Docker Swarm autoscaler spate.

Quick Start

$ docker network create -d overlay spate-demo

$ docker service create \
    --name spate \
    --network spate-demo \
    --constraint "node.role == manager" \
    --mount "type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock" \
    --replicas 1 \
    mtneug/spate

$ docker service create \
    --name producer \
    --network spate-demo \
    --constraint "node.role == manager" \
    --publish "5000:5000" \
    --mount "type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock" \
    --replicas 1 \
    mtneug/spate-demo producer

$ docker service create \
    --name consumer \
    --network spate-demo \
    --label "de.mtneug.spate=enable" \
    --label "de.mtneug.spate.autoscaler.period=2s" \
    --label "de.mtneug.spate.autoscaler.cooldown.scaled_up=5s" \
    --label "de.mtneug.spate.autoscaler.cooldown.scaled_down=5s" \
    --label "de.mtneug.spate.replica.min=1" \
    --label "de.mtneug.spate.replica.max=25" \
    --label "de.mtneug.spate.metric.demo.observer.period=1s" \
    --label "de.mtneug.spate.metric.demo.type=prometheus" \

    --label "de.mtneug.spate.metric.demo.target=10" \
    --replicas 5 \
    mtneug/spate-demo consumer
