一、准备
以下以前端的服务为例，前端 yaml 文件内容如下：
vi deploy-ui.yaml
apiVersion: v1
kind: Namespace
metadata:
name: shop-ui
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: manager-ui
namespace: shop-ui
spec:
replicas: 1
selector:
matchLabels:
app: manager-ui
template:
metadata:
labels:
app: manager-ui
spec:
containers:
- name: manager-ui
image: 192.168.1.48/shop-ui/manager-ui:4.2.3.7
ports:
- name: http
containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
name: manager-ui-service
namespace: shop-ui
spec:
selector:
app: manager-ui
ports:
- name: http
protocol: TCP
port: 80
targetPort: 80
nodePort: 10003
type: NodePort
二、更新镜像
1.方法一：修改 yaml 文件版本号并执行
将
image: 192.168.1.48/shop-ui/manager-ui:4.2.3.7
改为：
image: 192.168.1.48/shop-ui/manager-ui:4.2.3.8
执行：
kubectl apply -f deploy-ui.yaml
2.方法二：使用 set image
set image deploy manager-ui -n shop-ui *=192.168.1.48/shop-ui/manager-ui:4.2.3.8
3.方法三：使用 patch
patch deployment manager-ui -n shop-ui --patch \'{
"spec": {
"template": {
"spec": {
"containers": [{
"name": "manager-ui","image":"192.168.1.48/shop-ui/manager-ui:4.2.3.1"}]}}}}\'
