Hardware Requirements Guidelines for HA + Containers Implementation?
The GitLab CE hardware requirements seem to be oriented around a single "machine" running the entire stack: http://docs.gitlab.com/ce/install/requirements.html
We are running GitLab CE according to the AWS HA implementation (https://docs.gitlab.com/ce/university/high-availability/aws/) which offloads the Database and File System and uses Redis.
We are also using ECS for containers and have configured according to: https://docs.gitlab.com/ce/ci/docker/using_docker_images.html
The original hardware recommendations, nor the other two guides mention any overriding hardware requirements based on the efficiencies we should see with using HA and Containers.
We initially started with containers with a hard memory limit of 2 GB - but they are running at 99% memory utilization.
Is there any guidance on how to setup and tune hardware requirements for HA and/or Containers?
