README.md

Basic setup:

• launch two 'Hello World' nodes:
  • INSTANCE=1,2 CLOUD_CONFIG=helloworld/akka METADATA="akka=true" vagrant up
• launch a Cassandra node:
  • INSTANCE=3 CLOUD_CONFIG=cassandra METADATA="cassandra=true" vagrant up

Sanity checking compute nodes:

• add insecure Vagrant SSH keys:
  • ssh-add ~/.vagrant.d/insecure_private_key
• SSH into the core-01 compute node:
  • vagrant ssh core-01 -- -A
• check which compute nodes are present (along with their metadata tags):
  • fleetctl list-machines
• check that Fleet service scripts have been installed:
  • fleetctl list-unit-files
• check that all (expected) Docker Lift images have been downloaded:
  • docker images

Checking of Cassandra node:

• boot a Cassandra container:
  • fleetctl start cassandra
• check status of Cassandra:
  • fleetctl status cassandra
• check that Cassandra booted correctly:
  • fleetctl journal cassandra
  • journalctl (for general service starting failures)
• check Cassandra logging:
  • fleetctl ssh cassandra
  • docker logs cassandra

Checking of Akka cluster nodes:

• launch 3 'Hello World' micro-service:
  • fleetctl start app@{1..3}
• check that services have been launched:
  • fleetctl list-units
  • fleetctl list-unit-files
• view Akka cluster logging for a container:
  • fleetctl ssh app@1
  • docker logs app-1

Cluster formation:

• seed and form a cluster:
  • fleetctl start seed
• verify cluster formation:
  • fleetctl ssh app@1
  • docker logs app-1
