etcd添加新节点

第一步：etcd客户端执行
[root@k8s-master-1 ~]# etcdctl member add node180 https://109.105.1.180:2380
Added member named node180 with ID ead16f36d2aa4f03 to cluster
ETCD_NAME=“node180”
ETCD_INITIAL_CLUSTER=“k8s-ceph5=https://109.105.1.246:2380,node176=https: //109.105.1.176:2380,k8s-n2=https://109.105.1.208:2380,k8s-master-1=https://109.105.1.253:2380,k8s-master-2=https://109.105.1.254:2380,node180=https://109.105.1.180:2380”
ETCD_INITIAL_CLUSTER_STATE=“existing”
记住上面生成的参数，第二步使用
第二步：在节点执行
a.编辑/etc/etcd/etcd.config.yml
[root@node180 ~]# cat /etc/etcd/etcd.config.yml
name: ‘node180’
data-dir: /data/etcd
wal-dir: /data/etcd/wal

listen-client-urls: ‘https://0.0.0.0:2379’
max-snapshots: 5
max-wals: 5
cors:
initial-advertise-peer-urls: ‘https://109.105.1.180:2380’
advertise-client-urls: ‘https://109.105.1.180:2379’

enable-v2: true
enable-pprof: true
proxy: ‘off’
proxy-failure-wait: 5000
proxy-refresh-interval: 30000

proxy-read-timeout: 0
client-transport-security:
ca-file: ‘/etc/etcd/ssl/etcd-ca.pem’
cert-file: ‘/etc/etcd/ssl/etcd.pem’
key-file: ‘/etc/etcd/ssl/etcd-key.pem’
client-cert-auth: true
trusted-ca-file: ‘/etc/etcd/ssl/etcd-ca.pem’
auto-tls: true
peer-transport-security:

trusted-ca-file: ‘/etc/etcd/ssl/etcd-ca.pem’
auto-tls: true
debug: false
log-package-levels:
log-output: default
force-new-cluster: false
b.编辑/etc/kubernetes/manifests/etcd.yml
[root@node180 ~]# cat /etc/kubernetes/manifests/etcd.yml
apiVersion: v1
kind: Pod
metadata:
annotations:
scheduler.alpha.kubernetes.io/critical-pod: “”
labels:
component: etcd
tier: control-plane
name: etcd
namespace: kube-system
spec:
hostNetwork: true
containers:

• name: etcd
  image: registry.bst-1.cns.bstjpc.com:5000/gcr.io/google_containers/etcd-amd64:3.1.13
  command:
  • etcd
  • –config-file=/etc/etcd/etcd.config.yml
    livenessProbe:
    failureThreshold: 8
    tcpSocket:
    port: 2379
    initialDelaySeconds: 15
    timeoutSeconds: 15
    volumeMounts:
  • mountPath: /etc/etcd/ssl
    name: etcd-certs
  • mountPath: /etc/etcd/etcd.config.yml
    name: etcd-conf
  • mountPath: /data/etcd
    name: data
    volumes:
• hostPath:
  path: /etc/etcd/ssl
  type: DirectoryOrCreate
  name: etcd-certs
• hostPath:
  path: /etc/etcd/etcd.config.yml
  name: etcd-conf
• hostPath:
  path: /var/lib/etcd
  type: DirectoryOrCreate
  name: data
  第三步：加入完毕
  [root@k8s-master-1 manifests]# etcdctl member list
