1、为docker私有仓库导入账户密码信息：

kubectl create secret docker-registry myregistrykey --docker-server=DOCKER_REGISTRY_SERVER --docker-username=DOCKER_USER --docker-password=DOCKER_PASSWORD --docker-email=DOCKER_EMAIL

转换标准输出：kubectl get secret myregistrykey --output="jsonpath={.data.\.dockerconfigjson}" | base64 -d

2、查看信息是否生成：

kubectl get secrets myregistrykey

3、为访问kubernetes.api创建一个用户

编辑一个yaml格式文件：

apiVersion: v1
kind: ServiceAccount
metadata:
  name: build-robot
automountServiceAccountToken: false

通过 kubectl create -f file.yaml 生成 用户 build-robot

通过 kubectl get serviceaccount build-robot -o yaml 查看用户信息

可以顺便创建一个API令牌：

apiVersion: v1
kind: Secret
metadata:
  name: build-robot-secret
  annotations:
    kubernetes.io/service-account.name: build-robot
type: kubernetes.io/service-account-token

token可通过 kubectl get secret build-robot-secret -o yaml 获取（或通过describe命令获取）

4、接下来我们将之前的"myregistrykey"  加入build-robot用户，让之后在使用此账户时，可pull私有仓库的加密资源

 (1) 

kubectl get serviceaccounts build-robot -o yaml > ./ro.yaml

(2 ) 

kubectl get serviceaccounts default -o yaml > ./sa.yaml
$ cat ro.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  creationTimestamp: 2018-04-03T22:02:39Z
  name: build-robot
  namespace: default
  resourceVersion: "243024"
  selfLink: /api/v1/namespaces/default/serviceaccounts/default
  uid: 052fb0f4-3d50-11e5-b066-42010af0d7b6
secrets:
- name: build-robot-token

$ vi sa.yaml
[editor session not shown]
[delete line with key "resourceVersion"]
[add lines with "imagePullSecret:"]

$ cat sa.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  creationTimestamp: 2018-04-03T22:02:39Z
  name: build-robot
  namespace: default
  selfLink: /api/v1/namespaces/default/serviceaccounts/default
  uid: 052fb0f4-3d50-11e5-b066-42010af0d7b6
secrets:
- name: build-robot-token
imagePullSecrets:
- name: myregistrykey

$ kubectl replace serviceaccount default -f ./ro.yaml

这样在生成pod的yaml文件的编辑中，可使用如下账户在default空间下时，会自动调用myregistrykey

serviceAccount: build-robot

serviceAccountName: build-robot

或者在pod的yaml文件中，spec.imagepullsecrets下，添加- name: myregistrykey来忽略账户自带的key,直接pull自己私有仓库的项目：

apiVersion: v1
kind: Pod
metadata:
  name: private-reg
spec:
  containers:
  - name: private-reg-container
    image: <your-private-image>
  imagePullSecrets:
  - name: myregistrykey
