1.提前导入镜像
[root@worker232 ~]# wget http://192.168.15.253/Resources/Kubernetes/K8S%20Cluster/oldboyedu-slave-1.23.17.tar.gz
[root@worker232 ~]# docker load -i oldboyedu-slave-1.23.17.tar.gz
[root@worker232 ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
flannel/flannel v0.24.3 f6f0ee58f497 11 months ago 78.6MB
flannel/flannel-cni-plugin v1.4.0-flannel1 77c1250c26d9 12 months ago 9.87MB
registry.aliyuncs.com/google_containers/kube-proxy v1.23.17 f21c8d21558c 23 months ago 111MB
registry.aliyuncs.com/google_containers/coredns v1.8.6 a4ca41631cc7 3 years ago 46.8MB
registry.aliyuncs.com/google_containers/pause 3.6 6270bb605e12 3 years ago 683kB
[root@worker232 ~]#

[root@worker233 ~]# wget http://192.168.15.253/Resources/Kubernetes/K8S%20Cluster/oldboyedu-slave-1.23.17.tar.gz
[root@worker233 ~]# docker load -i oldboyedu-slave-1.23.17.tar.gz
[root@worker233 ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
flannel/flannel v0.24.3 f6f0ee58f497 11 months ago 78.6MB
flannel/flannel-cni-plugin v1.4.0-flannel1 77c1250c26d9 12 months ago 9.87MB
registry.aliyuncs.com/google_containers/kube-proxy v1.23.17 f21c8d21558c 23 months ago 111MB
registry.aliyuncs.com/google_containers/coredns v1.8.6 a4ca41631cc7 3 years ago 46.8MB
registry.aliyuncs.com/google_containers/pause 3.6 6270bb605e12 3 years ago 683kB
[root@worker233 ~]#

2.将worker节点加入到master集群（注意，不要复制我的，而是根据你上一步master生成的token加入集群）

[root@worker232 ~]# kubeadm join 10.0.0.231:6443 –token yad3sj.xzk89ul76gzy3by3 \
–discovery-token-ca-cert-hash sha256:199556ce471776cf36041e84e0ad76b2e9b5cfd6cf36729a2cc9789a45aad5e2

[root@worker233 ~]# kubeadm join 10.0.0.231:6443 –token yad3sj.xzk89ul76gzy3by3 \
–discovery-token-ca-cert-hash sha256:199556ce471776cf36041e84e0ad76b2e9b5cfd6cf36729a2cc9789a45aad5e2

3.验证worker节点是否加入成功

[root@master231 ~]# kubectl get no
NAME STATUS ROLES AGE VERSION
master231 NotReady control-plane,master 9m57s v1.23.17
worker232 NotReady 93s v1.23.17
worker233 NotReady 55s v1.23.17
[root@master231 ~]#
[root@master231 ~]# kubectl get no -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME

worker232 NotReady 95s v1.23.17 10.0.0.232 Ubuntu 22.04.4 LTS 5.15.0-119-generic docker://20.10.24
