- Use builtin task scheduling of ansible (same task on each host)
instead of manual looping on master
Benefits:
- One less play in remove-node.yml playbook
- Parralel node drain
- Drain parameters (timeout, grace period, retries,
allow_ungraceful_removal) can be adjusted separately for each node
with ansible variables
* Ensure entries for 1.23 are added for supported_versions vars
* cri-o: add support for kubernetes 1.23 but still use cri-o 1.22
* kubescheduler-config: diferentiate config versions based on kube_version
* registry: service add clusterIP, nodePort, loadBalancer support
* modify camelcase name to underscore
* Add registry service type compatibility check
* containerd: change default resolvconf_mode to host_resolvconf
* Wait for kube-apiserver to come back after pod refresh
* Handle resolv.conf gracefully
* Retain currently configured DNS entries to ensure we don't break the resolvers
* Suse uses wickedd for network management so no dhcp hooks
* Molecule: increase ansible timeout
* CI: Increase ansible timeout to 120s for Packet jobs
* Improve control plane scale flow (#13)
* Added version 1.20.10 of K8s
* Setting first_kube_control_plane to a existing one
* Setting first_kube_control_plane to a existing one
* change first_kube_master for first_kube_control_plane
* Ansible-lint changes
If trying to pull k8scsi/csi-resizer image from gcr.io, we face the error
like:
$ docker pull gcr.io/k8scsi/csi-resizer:v1.0.0
Error response from daemon: Head https://gcr.io/v2/k8scsi/csi-resizer/
manifests/v1.0.0: unknown: Project 'project:k8scsi' not found or deleted.
$
We can pull the image from quay.io instead.
This fixes the issue.
* containerd: add hashes for 1.5.8 and 1.4.12 and make 1.5.8 the new default
* containerd: make nerdctl mandatory for container_manager = containerd
* nerdctl: bump to version 0.14.0
* containerd: use nerdctl for image manipulation
* OpenSuSE: install basic nerdctl dependencies
* set ingress-nginx default terminationGracePeriodSeconds to 5 min for the drain of connection
* Add ingress_nginx_termination_grace_period_seconds at sample inventory
* Defaults: replace docker with containerd as our default container_manager
* CI: Use docker for download_localhost test
* Defaults: with container_manager=containerd we need etcd_deployment_type=host
* CI: Run weave jobs with docker
* CI: Vagrant don't download_force_cache
* CI: Fix upgrade tests
* should run compatible with old settings, this means docker
* we need to run with a distro that has at least modern containerd,
this means move from debian9 to debian10 to allow `containerd_version`
to match between 2.17 and master
* add metallb auto-assign property for main IP range & update addons.yml for sample inventory
* add new line at the end of file roles\kubernetes-apps\metallb\defaults\main.yml
* set default value for matallb_auto_assign = true
* Kata-containes: Fix for ubuntu and centos sometimes kata containers fail to start because of access errors to /dev/vhost-vsock and /dev/vhost-net
* Kata-containers: use similar testing strategy as gvisor
* Kata-Containers: adjust values for 2.2.0 defaults
Make CI tests actually pass
* Kata-Containers: bump to 2.2.2 to fix sandbox_cgroup_only issue
* Limit kubectl delete node to k8s nodes
This avoids the use of `kubectl delete node` when removing etcd nodes
which are not part of the cluser (separate etcd)
* Take errors into account when deleting node
There should not be error now that we're limiting the deletion to nodes
actually in the cluster
* Retrying on error
* Ensure addon-resizer 1.8.11 only effective at arch amd64.
k8s.gcr.io/addon-resizer:1.8.11 returns the amd64 image which is not executable at arm64.
Disable addon-resizer when the platform is not amd64.
When metrics-server upgrade and use addon-resizer:2.3, then revert this
commit and `image_arch` will determine the `addon_resizer_image_tag`.
* Add metrics_server_resizer architectures check
* Disable builtin ssl_session_cache solving the problem with OpenSSL consuming memory.
* Print warning only instead of error if no IngressClass permission is available.
* Containerd: download containerd from upstream instead of using distro specific packages
split runc download to separate role
make bootstrap-os role deploy container-selinux and seccomp libraries
clean up package manager provided containerd
move variables to docker role that are no longer common with containerd
* Containerd: make molecule testing more relevant
* replace ubuntu18 with ubuntu20
* add centos8 and debian11 to molecule tests
* run kubernetes/preinstall role to ensure relevancy
of test including dependency packages
* CI: adjust test scenarios for downloaded containerd
kube-bench scan outputs warning related to Calico like:
* text: "Ensure that the Container Network Interface file
permissions are set to 644 or more restrictive (Manual)"
* text: "Ensure that the Container Network Interface file
ownership is set to root:root (Manual)"
This fixes these warnings.
* netchecker: update images to 1.2.2 from Mirantis which is slightly less ancinet than the l23networks images
* Netchecker: use local etcd instead of kubernetes v1beta1 crds which are no longer suported by kube 1.22+
* Add Rocky as a known OS
* Make sure Rocky includes bootstrap-centos.yml
* Update docs with Rocky Linux
* Rocky Linux wireguard and EPEL
* Rocky Linux in the list of supported distributions
If the etcd cluster is separate and the etcd_deployment_type is "host",
there is no need for a container engine on the etcd nodes
Do not rely on a 'default(true)' filter, but define a proper default in
kubespray-defaults depending on etcd deployment method and if internal
or external etcd is used
to remove deprecation warning:
> Flag --feature-gates has been deprecated, This parameter should be set via the config file specified by the Kubelet's --config flag.
Kubespray deployment failed when using containerd backend on nodes that apparmor was not installed or previously removed. This PR ensure apparmor is installed by adding it into required_pkgs var.
The addon-resizer container can reduce resource limits of cpu and
memory of metrics-server container in the pod, and that caused
OOMKilled.
In addition, the original metrics-server manifest doesn't contain
the addon-resizer container as [1].
So this adds metrics_server_resizer option to control the addon-resizer
container deployment and the default value is false to make it stable
for most environments.

"allowPrivilegeEscalation: false" blocks deploying metrics-server
on CentOS7. In addition, the original metrics-server manifest doesn't
contain it as [1]. This removes it.

* Kata-Containers: add 2.2.0 hashes and make default
* Kata-Containers: replace 2.1.0 with bugfix version 2.1.1
* Kata-Containers: move to q35 a more modern VM architecture as 'pc' is removed in 2.2.0

The path of kubeconfig should be configurable, and its default value
is /etc/kubernetes/admin.conf. Most paths of the file are configurable
but some were not. This make those configurable.
