The script build.sh automatically builds a custom OS image for a VSphere environment. The original image of a selected OS is enriched with Kubernetes binaries, as well as (in the future) other custom files.

Currently supported operating systems:

• RedHat CoreOS
• Debian 9

./build.sh --target-os debian9 [--release K8S-RELEASE]

Parameters:

• --target-os is mandatory and specifies the Linux distribution image to be built. Possible values:
  • debian9
• --release specifies the Kubernetes release to be added to the image, e.g. v1.10.2. If not provided, the script will look up the latest stable release and use that.

The script will generate a VMDK disk image with the filename TARGET_OS-output.vmdk.
