  • 3 consul hosts
  • 1 Consul UI host
  • 2 Vault hosts
  • 3 RabbitMQ hosts
  • 3 Elastic search hosts
  • 1 Kibana host
  • 1+ logstash host
  • 1 Influx host
  • 1 Grafana host
  • 1 Jenkins host
  • 1+ Jenkins agent (potentially different OS's)
  • 1 Artefact server
  • 1 Proxy

Notes:

  • There are a number of resources in this environment of which there are multiple. That is done so that there is some redundancy in the resources, i.e. if one fails there will still be enough to keep going. Note that some resources, e.g. consul hosts, elasticsearch hosts and rabbitmq hosts, should be deployed in uneven numbers to prevent split brain situations. For more specific information read the clustering guides for the respective applications
  • It is wise to deploy the resources to different VM hosts so that a failure in one of the hosts does not lead to failures in the cluster

Environments

  • Need at least two environments so that you can have one test environment.
  • For some cases you want a third environment which is the one you use to build the resources so that resource creation / updates don't interfere with normal builds

Repositories

  • Need repositories for the code you want to build
  • All configurations should be stored in one or more repositories. Need to configure these so that you can push configurations to the different environments so you can test configuration changes as well.
    • Some configurations are environment specific. Ideally have as few of these as possible
