Deployment

Prerequisites

• Docker bridge network called internal.

  $ sudo docker network create internal
  $ sudo docker network ls | grep internal
  a6334ea8106d        internal            bridge              local
  

• DogStatsD running on the host.

  $ sudo cat /etc/datadog-agent/datadog.yaml | grep -e use_dogstatsd: -e dogstatsd_port: -e dogstatsd_non_local_traffic:
  use_dogstatsd: yes
  dogstatsd_port: 8125
  dogstatsd_non_local_traffic: yes
  

• Firewall rule to allow traffic from containers to the host on port 8125 (dogstatsd)

  $ sudo docker network inspect internal | grep -e Subnet -e Gateway
              "Subnet": "172.18.0.0/16",
              "Gateway": "172.18.0.1"
  $ sudo ufw allow from 172.18.0.0/16 to 172.18.0.1 port 8125
  $ sudo ufw status | grep 8125
  172.18.0.1 8125            ALLOW       172.18.0.0/24
