修改 APISERVER(MASTER)证书
kubeasz
创建集群后,APISERVER(MASTER)证书默认 CN 包含如下域名
和IP
:参见roles/kube-master/templates/kubernetes-csr.json.j2
"hosts": [
"127.0.0.1",
{% if groups['ex_lb']|length > 0 %}
"{{ hostvars[groups['ex_lb'][0]]['EX_APISERVER_VIP'] }}",
{% endif %}
{% for host in groups['kube_master'] %}
"{{ host }}",
{% endfor %}
"{{ CLUSTER_KUBERNETES_SVC_IP }}",
{% for host in MASTER_CERT_HOSTS %}
"{{ host }}",
{% endfor %}
"kubernetes",
"kubernetes.default",
"kubernetes.default.svc",
"kubernetes.default.svc.cluster",
"kubernetes.default.svc.cluster.local"
],
有的时候(比如apiserver地址通过边界防火墙的NAT转换成公网IP访问,或者需要添加公网域名访问)我们需要在 APISERVER(MASTER)证书中添加一些域名
或者IP
,可以方便操作如下:
1.修改配置文件/etc/kubeasz/clusters/${集群名}/config.yaml
# k8s 集群 master 节点证书配置,可以添加多个ip和域名(比如增加公网ip和域名)
MASTER_CERT_HOSTS:
- "10.1.1.1"
- "k8s.test.io"
#- "www.test.com"
2.执行新证书生成并重启apiserver
$ ezctl setup ${集群名} 04 -t change_cert,restart_master
