My k8s with kubespray always bails out at the following error "Too many nameservers. You can relax this check by set docker_dns_servers_strict=no and we will only use the first 3
In my cluster.yml I have this under - hosts - docker_dns_servers_strict: no but I still get the error. What am I missing?
In my case I added docker_dns_servers_strict: false in the all.yaml file. It's solved my problem.
As explained here, check the format of your yaml file.
Here is one example:
- hosts: k8s-cluster:etcd:calico-rr
any_errors_fatal: "{{ any_errors_fatal | default(true) }}"
vars:
- docker_dns_servers_strict: no
roles:
- { role: kubespray-defaults}
- { role: kernel-upgrade, tags: kernel-upgrade, when: kernel_upgrade is defined and kernel_upgrade }
- { role: kubernetes/preinstall, tags: preinstall }
- { role: docker, tags: docker }
- role: rkt
tags: rkt
when: "'rkt' in [etcd_deployment_type, kubelet_deployment_type, vault_deployment_type]"As mentioned in this issue:
This usually happens if you configure one set of dns servers on the servers before you run the kubespray role.
