My purpose is to create a cluster for a school project. I use this loader

I think i have error to connect because each time i reboot my destop, services are randomly redispatch between nodes up.

On my desktop, i have installed Aero DB and load without error all my data flow.

I use Haproxy to interact between my os and Docker. My docker config is precised in this topic

Here is my yml file : version: '3.2' services: aerospikedb: image: aerospike/aerospike-server:latest networks: - aerospikenetwork environment: - SERVICE\_PORTS=3000 ports: - target: 3000 published: 3000 protocol: tcp mode: host deploy: replicas: 4 endpoint\_mode: dnsrr labels: …

On my cluster with more memory, i up to 7 nodes and load.

The load has finish without stop writes but 2/3 of my data are in errors.
