Background

We currently run Zoekt on GitLab.com production and offer a Beta for Self-Managed customers. However, we don't have any guidance for upgrades and scalability like how we do for Elasticsearch.

Proposal

We should consider expanding our documentation to include:

• General scalability guidance
• Usage or at least a reference to it in architecture documentation
  • For example, our reference architecture includes a link to choosing your optimal cluster configuration
  • The chart install instructions are not explicit and you can make some assumptions based on the defaults
• Information around migrations or required checks for upgrade procedures (this may be none)
