Walkthrough

The README.md documentation for kubeadm installation was updated to simplify the kubeconfig setup commands. The changes remove quoted environment variable paths, command substitution quotes, and the interactive confirmation flag from three shell commands in the "Set Up Local kubeconfig" section.

Changes

Cohort / File(s)	Summary
Kubeconfig Setup Documentation Kubeadm_Installation_Scripts_and_Documentation/README.md	Simplified kubeconfig setup commands by removing quotes around $HOME and command substitutions; removed -i (interactive) flag from cp command

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Attention areas:
  • Verify whether removing quotes around $HOME expansion is intentional—quotes are generally safer for paths with potential whitespace
  • Confirm that removing the -i (interactive) flag from cp is desired behavior, as it may cause silent overwrites

Poem

🐰 With quotes removed and prompts unwound,
The config scripts now simplify sound,
Though shells grow bolder, less guarded and free,
The kubeconfig hops where it needs to be!
hop hop ✨

⚠️ Potential issue | 🟠 Major

Revert to quoted paths and command substitutions for shell safety.

The changes remove quotes around $HOME, $(id -u), and $(id -g), which violates shell scripting best practices. Unquoted variable and command substitution expansions are vulnerable to word-splitting and glob expansion if paths contain spaces or special characters. Additionally, the removal of the -i flag from cp changes behavior by making the command non-interactive.

Revert to the original quoted syntax to maintain shell safety:

- mkdir -p $HOME/.kube
- sudo cp /etc/kubernetes/admin.conf $HOME/.kube/config
- sudo chown $(id -u):$(id -g) $HOME/.kube/config
+ mkdir -p "$HOME"/.kube
+ sudo cp -i /etc/kubernetes/admin.conf "$HOME"/.kube/config
+ sudo chown "$(id -u)":"$(id -g)" "$HOME"/.kube/config

Per shell scripting best practices (POSIX, ShellCheck, Google Shell Style Guide), always quote variable expansions and command substitutions unless word-splitting is explicitly intended.

In Kubeadm_Installation_Scripts_and_Documentation/README.md around lines
135-137, the three commands dropped necessary quoting and the -i flag on cp;
restore shell-safe syntax by quoting $HOME (e.g., "$HOME"), quoting the
destination config path (e.g., "$HOME/.kube/config"), and quoting the command
substitutions for ownership (e.g., "$(id -u)" and "$(id -g)"); also restore the
interactive flag on cp (use sudo cp -i ...) so the copy remains interactive.
