[openstack-ansible][magnum-cluster-api]
I tried magnum-cluster-api on openstack ansible with Antelope version, I have finished creating the k8s control plane containers and then Run the magnum-cluster-api deployment, but at the time of running it an error was found, where the role openstack.osa.lxc_container_setup is not available, anyone knows how to solve it? root@aio1:/opt/openstack-ansible# openstack-ansible osa_ops.mcapi_vexxhost.k8s_install Variable files: "-e @/etc/openstack_deploy/user_secrets.yml -e @/etc/openstack_deploy/user_variables.yml -e @/etc/openstack_deploy/user_variables_octavia.yml " [WARNING]: Unable to parse /etc/openstack_deploy/inventory.ini as an inventory source [WARNING]: running playbook inside collection osa_ops.mcapi_vexxhost ERROR! the role 'openstack.osa.lxc_container_setup' was not found in osa_ops.mcapi_vexxhost:ansible.legacy:/etc/ansible/ansible_collections/osa_ops/mcapi_vexxhost/playbooks/roles:/etc/ansible/roles:/etc/ansible/roles/ceph-ansible/roles:/etc/ansible/ansible_collections/osa_ops/mcapi_vexxhost/playbooks The error appears to be in '/etc/ansible/ansible_collections/osa_ops/mcapi_vexxhost/playbooks/k8s_install.yml': line 36, column 15, but may be elsewhere in the file depending on the exact syntax problem.

Hey, This role is available in our collection on current master [1]. In previous versions (like antelope) this was a shared playbook [2]. Eventually, capi driver support was made and tested only with 2024.1, it can work with 2023.1 but with bunch of adjustments only. Hope this helps.

I'm not 100% sure, but I think it might be needed on Ansible deploy host. I guess I would try installing via /opt/ansible-runtime/bin/pip3 install docker-image-py In master we have implemented ability to define extra requirements to be installed on controller by creating file /etc/openstack_deploy/user-ansible-venv-requirements.txt [1] [1] https://opendev.org/openstack/openstack-ansible/commit/5b57f10eeccca16771de7...

Frankly speaking, I'm really not aware about Vexxhost collection at all. But your point about LXC rw issue reminded me about this extra config we use in CI to make LXC bind mount some required paths in rw here: https://opendev.org/openstack/openstack-ansible-ops/src/branch/master/mcapi_... But really no idea if that's related to the issue or not. On Fri, Apr 19, 2024, 19:57 <pahrialtkj@gmail.com> wrote:

Then I change manually cgroupDriver from systemd to cgroupfs, after that installation process continues and stuck again with this error :
TASK [vexxhost.kubernetes.kubernetes : Allow workload on control plane node] ********************************************************************************************* An exception occurred during task execution. To see the full traceback, use -vvv. The error was: urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='172.29.236.101', port=6443): Max retries exceeded with url: /version (Caused by SSLError(SSLEOFError(8, '[SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1007)')))
If I check from systemctl status kubelet, these the logs :
kubelet.go:1511] "Failed to start ContainerManager" err="[open /proc/sys/kernel/panic: read-only file system, open /proc/sys/kernel/panic_on_oops: read-only file system, open /proc/sys/vm/overcommit_memory: read-only file system]"
Is this because the lxc config is still not rw so it happens like that?
