This commit enhances the node removal playbook's reliability and safety by implementing the following changes:
1. **Node Validation**: Added a validation step using assert to ensure the `node` variable is defined and contains nodes. If the list is empty or undefined, the playbook fails early, preventing accidental operations on the entire cluster.
2. **Removed Defaulting for Hosts**: Updated tasks to enforce explicit `node` variable input without defaulting to critical groups (e.g., `etcd:k8s_cluster:calico_rr`). By validating `node` beforehand, tasks now solely rely on user-provided input and safely avoid unintended targeting.
3. **Explicit User Confirmation**: Enhanced the confirmation prompt to clarify the scope of the operation. The admin is now required to explicitly confirm node state deletion, ensuring a deliberate decision before proceeding.
These improvements strengthen the reliability and safety of the `remove-node.yml` playbook by eliminating ambiguous behavior, preventing misconfigurations, and ensuring clear interaction during node removal tasks.
Our README is currently pretty cluttered:
- Part of the README duplicates docs/getting_started/getting-started.md
-> Remove duplicates and extract useful info into the getting-started.md
- General info on Ansible environment troubleshooting
-> remove most of it as it's not specific to Kubespray, move to
docs/ansible/ansible.md
-> split inventory-related stuff of ansible.md into it's own file. This
should host documentation on how to manages Kubespray inventories in the
future.
ansible.md:
- remove the list of "Unused" variables, as:
1. It's not accurate
2. What matters is where users should put their variables
