JAlgoArena Nomad

Nomad jobs to run JAlgoArena microservices

Step 0

In order to successfully run nomad scheduler plus all microservices, we have to run Consul and Nomad agents on every host where we want to deploy JAlgoArena

Step 1

Now we are ready to run external services that JAlgoArena is using for it's own purpose

• kafka cluster (plus zookeeper)
• elastic search, logstash and kibana for logs monitoring
• prometheus (will be added in a near future ...)
• traefik - edge service and load balancer for rest and websocket calls
• cockroachDB - persistent storage for JAlgoArena (will be added in a near future ...)

Here, single manual step is to run create_kafka_topics.sh in order to properly set kafka topics replication and partitions (To Be Automated!).

Step 2

We can start running JAlgoArena specific services - which depends on external services:

• auth
• queue
• events
• judge
• submissions
• ranking
• ui

All services are deployed in Highly Available mode keeping some set of replication
