关于kubernetes:minikube-master-节点的-docker-用户的密码什么

先看下 node 的 ip 地址

╰─➤  kubectl get nodes -o wide                               
NAME       STATUS   ROLES                  AGE     VERSION   INTERNAL-IP    EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME
minikube   Ready    control-plane,master   4d21h   v1.23.9   192.168.49.2   <none>        Ubuntu 20.04.5 LTS   5.15.0-56-generic   docker://20.10.20

然而间接登录 docker node 会失败!

╰─➤  ssh docker@192.168.49.2                                                                                                                                                                                                                                                          130 ↵

查了一下,能够不必账号密码,而是密钥对登录

指定公钥地址,就能够了

╰─➤  ssh -i ~/.minikube/machines/minikube/id_rsa docker@192.168.49.2              
docker@minikube:~$ 
docker@minikube:~$ 

参考:How do I ssh into the VM for Minikube?
