See the table below for supported Kubernetes versions:
The default Shipmight stack installation has been optimized to require as little resources as possible in order to run everything at small scale.
See the table below for a list of pods installed in Shipmight stack (shown values are resource limits; requests may be even lower).
There are some additional jobs (e.g. shipmight install, cert-manager startup api check) which consume resources for a short time.
Any extra resources in your cluster are left for your applications.
Note that you should always have spare resources in the cluster or turn on auto-scaling for your node groups to ensure that Kubernetes is able to run occasional jobs and recycle and reschedule pods when needed.
You can scale each component individually.
