[Lab Notes] Kubernetes the Hard Way, For Real This Time (Step 06)
Continuing my Kubernetes the Hard Way homelab build. Steps 01-05 are already done, this covers step 06. Original guide: 06-data-encryption-keys.md Thoughts I had while doing this This step was pretty straightforward, just generate an encryption key and an encryption config file. But it did make me think back to step 04, where I set up the TLS/CA cert. Aren't both steps just "setting up…
In the "Kubernetes the Hard Way" homelab build, step 06 focused on generating an encryption key and configuring encryption for Kubernetes Secrets stored in etcd. The original guide can be found at 06-data-encryption-keys.md. The process was straightforward, involving the generation of a random 32-byte encryption key and the use of it to fill in an encryption config file, which was then copied to the controller.
This step was distinct from step 04, which set up TLS/CA for securing data in transit between Kubernetes components over the network. Instead, step 06 concentrated on protecting data at rest, specifically the Secrets stored in etcd, ensuring they were not left in plain text on disk.
