Prior to this change, configure.sh would: (1) compare versions of built-in kubelet and downloaded kubelet, and (2) bind-mount downloaded kubelet at /usr/bin/kubelet in case of version mismatch With this change, configure.sh: (1) compares the two versions only on test clusters, and (2) uses the actual file paths to start kubelet w/o any bind-mounting To allow (2), this change also provides its own version of kubelet systemd service file. Effectively with this change we will always use the downloaded kubelet binary along with its own systemd service file on non-test clusters. The main advantage is this change does not rely on the kubelet being built in to the OS image.
Google Container-VM Image (GCI)
GCI is a container-optimized OS image for the Google Cloud Platform (GCP). We built GCI primarily for running Google services on GCP. Unlike the open preview version of container-vm, Google Container-VM Image is based on the open source Chromium OS project, allowing us greater control over the build management, security compliance, and customizations for GCP.
