When trying to run print_hostnames of inventory.py, it outputs the following
error:
$ CONFIG_FILE=./test-hosts.yaml python3 ./inventory.py print_hostnames
Traceback (most recent call last):
File "./inventory.py", line 472, in <module>
sys.exit(main())
File "./inventory.py", line 467, in main
KubesprayInventory(argv, CONFIG_FILE)
File "./inventory.py", line 92, in __init__
self.parse_command(changed_hosts[0], changed_hosts[1:])
File "./inventory.py", line 415, in parse_command
self.print_hostnames()
File "./inventory.py", line 455, in print_hostnames
print(' '.join(self.yaml_config['all']['hosts'].keys()))
KeyError: 'all'
because it is missed to load a hosts config file before printing hostnames.
This fixes the issue.
* Fix: adding new ips with inventory builder (#7577)
* moved conflig loading logic
to after checking whether the config
should be loaded, and added check for
whether the config should be loaded
* added check for removing nodes from config
if the user wants to remove a node, we
need to load the config
* Fix tox errors
The main functions are wrapped by a sys.exit function which expects and
argument. The curent implementation isn't returning values in all cases.
This change ensures main functions return a value in all cases.
* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones
This replaces kube-master with kube_control_plane because of [1]:
The Kubernetes project is moving away from wording that is
considered offensive. A new working group WG Naming was created
to track this work, and the word "master" was declared as offensive.
A proposal was formalized for replacing the word "master" with
"control plane". This means it should be removed from source code,
documentation, and user-facing configuration from Kubernetes and
its sub-projects.
NOTE: The reason why this changes it to kube_control_plane not
kube-control-plane is for valid group names on ansible.

This replaces KUBE_MASTERS with KUBE_CONTROL_HOSTS because of [1]:

This variable was added as KUBE_MASTERS_MASTERS. That's probably a typo.
Remove the redundant `_MASTERS` suffix. Also, document the variable in the
help message.
inventory_builder creates hosts.yaml file with hostnames like "node1",
"node2", etc. Even if specifying override_system_hostname=false, the
output of "kubectl get nodes" shows those hostnames ("node1", etc.)
without using actual hostnames.
To solve this issue, this adds an option USE_REAL_HOSTNAME to get
actual hostnames when creating hosts.yaml file instead of "node1", etc.
* add to inventory.py script ability to indicate ip ranges
* add test for range2ip function for inventory.py script
some fixes
* add negative test for range2ip function for inventory.py script
This does not address per-node certs and scheduler/proxy/controller-manager
component certs which are now required. This should be handled in a
follow-up patch.
Also adds calico-rr group if there are standalone etcd nodes.
Now if there are 50 or more nodes, 3 etcd nodes will be standalone.
If there are 200 or more nodes, 2 kube-masters will be standalone.
If thresholds are exceeded, kube-node group cannot add nodes that
belong to etcd or kube-master groups (according to above statements).
