1、kubectl describe pod tomcat-ccbc756f6-bh6wg  #查看信息如下报错

 2、在node节点

[root@linux-node2 ~]# cat .docker/config.json |base64 -w 0

        "192.168.56.11": {
            "auth": "emp5OjEyMzQ1NkEuY29t"
        }
    },
    "HttpHeaders": {
        "User-Agent": "Docker-Client/18.03.0-ce (linux)"
    }
}You have new mail in /var/spool/mail/root
[root@linux-node2 ~]#  cat .docker/config.json

            "auth": "emp5OjEyMzQ1NkEuY29t"

.docker/config.json文件

3、在master节点创建registry-pull-sercret.yaml文件

[root@linux-node1 daemon]# cat registry-pull-sercret.yaml
apiVersion: v1
kind: Secret
metadata:
  name: registry-pull-sercet
data:
  .dockerconfigjson: ewoJImF1dGhzIjogewoJCSIxOTIuMTY4LjU2LjExIjogewoJCQkiYXV0aCI6ICJlbXA1T2pFeU16UTFOa0V1WTI5dCIKCQl9Cgl9LAoJIkh0dHBIZWFkZXJzIjogewoJCSJVc2VyLUFnZW50IjogIkRvY2tlci1DbGllbnQvMTguMDMuMC1jZSAobGludXgpIgoJfQp9
type: kubernetes.io/dockerconfigjson

registry-pull-sercret.yaml

4、创建

kubectl apply -f registry-pull-sercret.yaml

5、修改tomcat.yaml

[root@linux-node1 daemon]# cat deploy-tomcat.yaml
