Change base image to Alpine by jimsihk · Pull Request #47 · jimsihk/codespace-oke-k8s

jimsihk · 2025-10-19T06:36:05Z

Summary

Updated the Dockerfile to use Alpine as the base image and added necessary packages for Kubernetes and OCI CLI.

Key highlights:

use Alpine Linux as base image for minimal size and dependencies
install packages from source for latest version (remove dependency on community build)
set custom scripts as alias for easier access

About oci-cli installation:

install from source install.py

total build time: ~15min
run time: ~0.6s

use uv instead of pip for oci-cli for smaller image size (require patching of the script):

total build time ~5min
run time: ~2s

install from alpine package

total build time: ~3min
run time: ~0.6s
version may lag behind

TODO:

find best way for oci-cli installation
setup renovate to trigger auto PR
setup auto complete of oci commands

Updated the Dockerfile to use Alpine as the base image and added necessary packages for Kubernetes and OCI CLI.

Add echo statement to display the PATH environment variable
