Design and management of etcd deployment within the SDP for AA0.5

etcd is a highly available, distributed key/value store, which has been selected as the solution for the SDP configuration database.

As with any other database, the SDP configuration DB needs a strategy and design for the deployment and management of a highly available solution in the production environment.

This feature gathers the requirements, and proposes a design for the deployment and management of a highly available etcd solution that integrates with the current delivery tools and environments supporting development, test, and production for AA0.5

In confluence:

• the operational requirements for the SDP configuration database are identified and documented
• a strategy for managing (deployment, upgrade, configuration) of etcd is documented so that it can be implemented to coexist with the existing software delivery and deployment infrastructure

The operator we are speaking is the aenix etcd operator.
The version we tested was 0.3.1. The 3 and 5 nodes deployment was fixed.
Documentation here

Defragmentation is still missing but it should come soon since they are working on that feature.
The operator is good enough for SDP to use it for production or CI/CD.
We agreed to start using it as an option on SDP charts.
