[Lab Notes] Kubernetes the Hard Way, For Real This Time (Step 07)
Continuing my Kubernetes the Hard Way homelab build. Steps 01-06 are already done, this covers step 07. Original guide: 07-bootstrapping-etcd.md Thoughts I had while doing this This step sets up the etcd cluster. From what I understand, etcd is basically Kubernetes' database, it's where the "state" of the whole cluster gets stored. Quick TLDR before the actual steps: grab the etcd…
In the seventh step of the Kubernetes the Hard Way process, the home lab build progressed to setting up the etcd cluster. Etcd serves as the central database for Kubernetes, storing the state of the entire cluster. The guide outlined grabbing the etcd binaries and service file, copying them to the controller/server node, and then installing and configuring etcd as a systemd service, ultimately resulting in a functioning etcd Linux service on the controller.
Prerequisites included transferring the etcd and etcdctl binaries to the server, followed by installing and configuring the etcd server. This involved creating relevant directories, granting permissions, and copying necessary certificates. The etcd service file was then moved to the systemd system directory.
Finally, the etcd server was started, and the system was updated to enable the etcd service on boot. Verification confirmed that etcd was running as a single-member cluster named "controller". By following the guide meticulously, the etcd installation and setup were completed without any deviations.
