Context
Set up stack to monitor the K8S cluster, worker nodes and extra K8S metrics. Add pod monitor for indexer instance.
Proposed Changes
Install
kube-prometheusstack which gives us:Set up monitoring for pods belonging to the
indexerrunning in dev cluster.This PR also creates an AWS managed prometheus along with necessary roles to interact with it. But the
remote_writeis not hooked up because, the version of operator installed does not supportSigV4authentication. K8S cluster needs to be upgraded for us to install a newer version, and that will be done in future PRs. For now, this PR installs a grafana instance accessible locally via port forwarding that lets us make progress while we figure out how to hook up things to PL grafana.Unrelated to context: while at it, give Kyle access to interact with encrypted secrets like the rest of the team.
Tests
Deployed manually for testing.
