The upgrade process (docs) follows the general procedure of:

- Upgrading the Kubernetes control plane with kubeadm (Kubernetes components and add-ons excluding the CNI)
- If applicable upgrading the CNI network plugin
- Upgrading the Kubernetes packages (kubelet, kubeadm, kubectl) on the control plane and worker nodes
- Upgrading the kubelet config on worker nodes with kubeadm

# check cluster nodes and version
kubectl  get no  -owide

⚠️ Avoid being stuck in tutorial hell and always use the official documentation.

Pipeline

An automated process that defines a series of stages or steps to build, test and deploy SW solutions.

Continuous Integration (CI)

Buildkit

BuildKit is the image building engine inside Docker. It's not part of other container runtimes - like containerd - but you can run a BuildKit server in a container. docker build uses Buildx and BuildKit by default since Docker Engine 23.0.

You can install BuildKit by either running it natively via systemd or in a container.

BuildKit can also be built in a version that tightly integrates with containerd, using an existing containerd daemon for the storage and sharing it with other containerd clients.
