The `containerd-common` role is responsible for gathering OS specific variables from the vars directory of the roles that include or import it. `containerd-common` is imported via role dependency by a total of two roles, `container-engine/docker`, and `container-engine/containerd`.
containerd-common is needed by both the docker and containerd roles as a dependency when:
- containerd is selected as the container engine
- a docker install is detected and needs to be removed
- apt is the package manager
However, by default, roles can not be invoked more than once in the same play, unless `allow_duplicates: true` is set for that role. This results in the failure of the `containerd | Remove containerd repository` task, since only the docker vars will be loaded in the play, and `containerd_repo_info.repos`, normally populated by containerd/vars, is left empty.
This change sets `allow_duplicates: true` for `containerd-common` which fixes the currently failing containerd tasks if docker was detected and removed in the same play.
by setting a default runtime spec with a patch for RLIMIT_NOFILE.
- Introduces containerd_base_runtime_spec_rlimit_nofile.
- Generates base_runtime_spec on-the-fly, to use the containerd version
of the node.
For the following configuration
```
containerd_insecure_registries:
docker.io:
- dockerhubcache.example.com
```
the rendered /etc/containerd/config.toml contains
```
[plugins."io.containerd.grpc.v1.cri".registry.configs."docker.io".tls]
insecure_skip_verify = true
```
but it needs to be
```
[plugins."io.containerd.grpc.v1.cri".registry.configs."dockerhubcache.example.com".tls]
insecure_skip_verify = true
```
* Update main.yaml
* remove version in dpkg_selection name
* make lint happy
* Fix typo
* add comment / remove useless contition
* remove dpkg hold in reset tasks
* feat: make kubernetes owner parametrized
* docs: update hardening guide with configuration for CIS 1.1.19
* fix: set etcd data directory permissions to be compliant to CIS 1.1.12
* extra admission controls now don't have a version in their file names
eventratelimit.v1beta2.yaml.j2 -> eventratelimit.yaml.j2
* cri_socket variable includes the unix:// prefix to be conformat with
upstream
When running molecule jobs, we saw the folloing warning message:
[DEPRECATION WARNING]: [defaults]callback_whitelist option, normalizing names
to new standard, use callbacks_enabled instead. This feature will be removed
from ansible-core in version 2.15. Deprecation warnings can be disabled by
setting deprecation_warnings=False in ansible.cfg.
callbacks_enabled has been added since Ansible 2.11 and Kubespray is using
Ansible 2.12 at master branch. So we can use callbacks_enabled safely to
avoid the warning message.
* Force containerd service unmasking
Force systemd to unmask and start service when adding containerd service
* Eliminate restart and move unmasking step
Switch to start instead of restart
Move unmasking to restart handler
* Add unmasking to similar container runtimes
* Add missing service names
When running cluster.yml for new machines what containerd is already
install but Kubernetes cluster were not installed before, the task
"remove-node | List nodes" is failed like
"changed": false,
"cmd": [
"/usr/local/bin/kubectl", "--kubeconfig",
"/etc/kubernetes/admin.conf", "get", "nodes", "-o",
"go-template={{ range .items }}{{ .metadata.name }}
{{ "\n" }}{{ end }}"
],
..
"stderr": "error: stat /etc/kubernetes/admin.conf: no such file or directory",
That was due to lack to check the existing Kubernetes cluster exists
or not before running "kubectl drain" command.
This adds the check to avoid the issue.
* Add epoch to docker-ce and docker-ce-cli packages to ensure docker upgrade
* Split container-engine redhat vars to support legacy RHEL 7 version management
* Support ansible_distribution_major_version when disvering vars with ansible_os_family
This fixes the following types of failures:
- empty-string-compare
- literal-compare
- risky-file-permissions
- risky-shell-pipe
- var-spacing
In addition, this changes .gitlab-ci/lint.yml to block the same issue
by using the same method at Kubespray CI.
When running ansible-lint directly, we can see a lot of warning
message like
risky-file-permissions File permissions unset or incorrect
This fixes the warning messages.
* Update config.toml.j2
i think this commit code is not completed works
exam registry address : a.com:5000
insecure registry must be http://a.com:5000
but this code add insecure a.com:5000 (without http://)
If there is no http, containerd accesses with https even if insecure_skip_verify = true
solution is code edit
* Update config.toml.j2
* Update containerd.yml
* Update containerd.yml
* Update containerd.yml
* Update config.toml.j2
* 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
* 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
* 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
* 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
* 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.
* 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
* 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
* Fix missing file mode (risky-file-permissions)
Found this using ansible-lint.

* Fix another missing file mode (risky-file-permissions)
This one fixes `/etc/crio/config.json`
