从目录部署映像

Question

我参考了本教程来创建可部署的映像：

https://medium.com/@javatechie/kubernetes-tutorial-run-deploy-spring-boot-application-in-k8s-cluster-using-yaml-configuration-3b079154d232

我想使用这个舵图来部署目录中的映像：

apiVersion: apps/v1
kind: Deployment # Kubernetes resource kind we are creating
metadata:
  name: spring-boot-k8s
spec:
  selector:
    matchLabels:
      app: spring-boot-k8s
  replicas: 2 # Number of replicas that will be created for this deployment
  template:
    metadata:
      labels:
        app: spring-boot-k8s
    spec:
      containers:
        - name: spring-boot-k8s
          image: springboot-k8s-example:1.0 
# Image that will be used to containers in the cluster
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 8080 
# The port that the container is running on in the cluster

如何从目录或从url链接的私有码头注册中心部署坞映像springboot-k8s-example:1.0？

Answer 1

在这里，您需要创建一个图像提取秘密，以便从您自己的存储库中提取图像。我已经复制了您的问题，并将图像推送到我的女贞码头注册中心，然后成功地提取了图像。

这可以通过使用下面的命令来完成--我假设您使用的是坞女贞注册表：

kubectl create secret docker-registry regcred --docker-server=https://index.docker.io/v1/ --docker-username=<docker-username> --docker-password=<your-password> --docker-email=<docker-email

这将创建一个秘密，现在您需要将其添加到部署清单中，以便它可以通过女贞注册表进行身份验证以获取映像。

apiVersion: apps/v1
kind: Deployment # Kubernetes resource kind we are creating
metadata:
  name: spring-boot-k8s
spec:
  selector:
    matchLabels:
      app: spring-boot-k8s
  replicas: 2 # Number of replicas that will be created for this deployment
  template:
    metadata:
      labels:
        app: spring-boot-k8s
    spec:
      containers:
        - name: spring-boot-k8s
          image: sidharthpai/springboot-k8s-example:1.0
# Image that will be used to containers in the cluster
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 8080
      imagePullSecrets:
      - name: regcred

现在，要准备舵图，您需要创建一个具有相关名称的图表，然后在舵图( Deployment.yml & Secret.yml )中配置template.Once，这是您需要配置的values.yml。

Deployment.yml (模板)

apiVersion: apps/v1
kind: Deployment # Kubernetes resource kind we are creating
metadata:
  name: {{ .Values.name}}
spec:
  selector:
    matchLabels:
      app: {{ .Values.app}}
  replicas: 2 # Number of replicas that will be created for this deployment
  template:
    metadata:
      labels:
        app: {{ .Values.app}}
    spec:
      containers:
        - name: {{ .Values.name}}
          image: {{ .Values.image}}
# Image that will be used to containers in the cluster
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 8080
      imagePullSecrets:
      - name: {{ .Values.secret_name}}

Secret.yml(模板)

apiVersion: v1
data:
  .dockerconfigjson: {{ .Values.docker_config}}
kind: Secret
metadata:
  name: {{ .Values.secret_name}}
type: kubernetes.io/dockerconfigjson

Values.yml

name: spring-boot-k8s
app: spring-boot-k8s
image: sidharthpai/springboot-k8s-example:1.0
secret_name: regcred
docker_config: <docker-config-value>
