Kubernetes OIDC Flow - Sig-Auth

Got some answers from #sig-auth: https://kubernetes.slack.com/archives/C0EN96KUY/p1667201299188199

• OIDC generally, it's not good practice to contact the IdP on every request
• Token:

Abstract

Bolt operations are copy-on-write. When a page is updated, it is copied to a completely new page. The old page is added to a "freelist", which Bolt refers to when it needs a new page. This means that deleting large amounts of data will not actually free up space on disk, as the pages are instead kept on Bolt's freelist for future use. In order to free up this space to disk, you will need to perform a defrag.

The process of defragmentation releases this storage space back to the file system. Defragmentation is issued on a per-member so that cluster-wide latency spikes may be avoided.

Algorithm

1. lock batchTx to ensure nobody is using previous tx, and then close previous ongoing tx.
2. lock database after lock tx to avoid deadlock.

1. Export all the required environment variables:

export $(grep -v '^#' /etc/etcd.env | xargs -d '\n')

2. Start interacting with etcdctl

etcdctl endpoint health status --cluster -w table && etcdctl endpoint status --cluster -w table
