-- only required ports leaved open, other firewalled.
-- to access ec2 server a ssh provate key had generated and keept locally only on this server.
-- an smtp relay gets installed and configured to use gmail.
-- cdt configures outgoing mail for all tools. so apps can send notifications to team.
-- all application data created by the tools is persisted and located on /opt/docker-volumes, so it is easy to backup, migrate
-- cdt install prometheus and grafana and creates grafana dashboards for tools.
-- grafana can also be used to monitor applications created by team.
-- cdt uses official docker images for tools and tools can be updated easily.
-- when a self signed cert is generated, all apps made trust the grnerated certificate.
