in flag
Artur

I can not install the containerd in kubespray

Parameters:

##docker for docker, crio for cri-o and containerd for containerd.

container_manager: containerd

etcd_deployment_type: host

When installing :

TASK [kubernetes/control-plane : kubeadm | aggregate all SANs] *********************************************************************************************************************** fatal: [master-0]: FAILED! => {"msg": "Unexpected templating type error occurred on ({{ (sans_base + groups['kube_control_plane'] + sans_lb + sans_lb_ip + sans_supp + sans_access_ip + sans_ip + sans_address + sans_override + sans_hostname + sans_fqdn) | unique }}): can only concatenate list (not "str") to list"} fatal: [master-1]: FAILED! => {"msg": "Unexpected templating type error occurred on ({{ (sans_base + groups['kube_control_plane'] + sans_lb + sans_lb_ip + sans_supp + sans_access_ip + sans_ip + sans_address + sans_override + sans_hostname + sans_fqdn) | unique }}): can only concatenate list (not "str") to list"} fatal: [master-2]: FAILED! => {"msg": "Unexpected templating type error occurred on ({{ (sans_base + groups['kube_control_plane'] + sans_lb + sans_lb_ip + sans_supp + sans_access_ip + sans_ip + sans_address + sans_override + sans_hostname + sans_fqdn) | unique }}): can only concatenate list (not "str") to list"}

Hi Artur welcome to S.F. Please [edit your question](https://serverfault.com/posts/1080240/edit) and fix the formatting. One will also observe that the error in question references the various **sans** variables, and has nothing to do with containerd, so you are likely asking the wrong question and have unquestionably provided the wrong snippets of your config. Good luck

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
