首先是Weblogic的Docker部署。
请仔细阅读：https://my.oschina.net/u/3867634/blog/2246865
至此，我们已经构建了oracle/weblogic:12.2.1.3-developer镜像，为了方便后续使用，我们可以搭建Harbor本地私有镜像仓库，将次镜像push至仓库中。
搭建Harbor仓库
请参阅：https://github.com/goharbor/harbor/blob/release-1.6.0/docs/installation_guide.md
中文版：https://blog.csdn.net/aixiaoyang168/article/details/73549898
搭建完成后，kubernetes节点中需要修改insecure-registry：
//编辑配置docker-option配置文件 vi /etc/systemd/system/docker.service.d/docker-options.conf //在文件中添加 --insecure-registry=172.17.20.25 [Service] Environment="DOCKER_OPTS=--insecure-registry=10.233.0.0/18 --insecure-registry=172.17.20.25 --graph=/var/lib/docker --log-opt max-size=50m --log-opt max-file=5 \ --iptables=false" //重启docker systemctl daemon-reload systemctl restart docker
然后，将构建好的镜像push至仓库中：
//给image打标签 docker tag oracle/weblogic:12.1.3-developer 172.17.20.25/oracle/weblogic:12.1.3-developer //push至172.17.20.25 docker push 172.17.20.25/oracle/weblogic:12.1.3-developer
现在，可以登录至http://172.17.20.25查看镜像
拉取镜像：
docker pull 172.17.20.25/oracle/weblogic:12.2.1.3-developer
kubernetes集群中部署Weblogic
拉取docker-images代码：
$ git clone https://github.com/oracle/docker-images.git //进入wls-k8s-domain目录 [root@localhost ~]# cd docker-images/OracleWebLogic/samples/wls-k8s-domain/ [root@localhost wls-k8s-domain]# ls build.sh container-scripts Dockerfile k8s README.md
构建wls-k8s-domain镜像：
$ docker build -t wls-k8s-domain .
将镜像tag打成172.17.20.25/oracle/wls-k8s-domain:1.0后push至Harbor以方便k8s节点拉取。
再修改k8s/wls-admin.yml为如下所示：
apiVersion: apps/v1beta1 kind: Deployment metadata: name: admin-server spec: selector: matchLabels: app: admin-server replicas: 1 template: metadata: labels: app: admin-server spec: podAntiAffinity: requiredDuringSchedulingIgnoredDuringExecution: - labelSelector: matchExpressions: - key: app operator: In values: - admin-server topologyKey: "kubernetes.io/hostname" containers: - name: admin-server #image修改为harbor上的名字 image: 172.17.20.25/oracle/wls-k8s-domain:1.0 imagePullPolicy: IfNotPresent command: ["sh"] args: ["/u01/oracle/startadmin.sh"] readinessProbe: httpGet: path: /weblogic/ready port: 8001 initialDelaySeconds: 15 timeoutSeconds: 5 ports: - containerPort: 8001 env: - name: WLUSER valueFrom: secretKeyRef: name: wlsecret key: username - name: WLPASSWORD valueFrom: secretKeyRef: name: wlsecret key: password volumeMounts: - mountPath: /u01/wlsdomain name: domain-home volumes: - name: domain-home persistentVolumeClaim: claimName: wlserver-pvc-1 --- apiVersion: v1 kind: Service metadata: name: admin-server labels: app: admin-server spec: type: NodePort selector: app: admin-server ports: - name: client protocol: TCP port: 8001 targetPort: 8001 nodePort: 30007 selector: app: admin-server
修改k8s/wls-stateful.yml为：
apiVersion: apps/v1beta1 # for versions before 1.6.0 use extensions/v1beta1 kind: StatefulSet metadata: name: managed-server spec: serviceName: wls-subdomain selector: matchLabels: app: managed-server replicas: 2 template: metadata: name: ms labels: app: managed-server spec: #将managed-server与admin-server部署在同一个node上 affinity: podAffinity: requiredDuringSchedulingIgnoredDuringExecution: - labelSelector: matchExpressions: - key: app operator: In values: - admin-server topologyKey: "kubernetes.io/hostname" subdomain: wls-subdomain containers: - name: managed-server image: 172.17.20.25/oracle/wls-k8s-domain:1.0 imagePullPolicy: IfNotPresent command: ["sh"] args: ["/u01/oracle/startms.sh"] readinessProbe: httpGet: path: /weblogic/ready port: 8011 initialDelaySeconds: 15 timeoutSeconds: 5 ports: - containerPort: 8011 env: - name: JAVA_OPTIONS value: "-Dweblogic.StdoutDebugEnabled=true" - name: USER_MEM_ARGS value: "-Xms64m -Xmx256m " - name: MY_POD_IP valueFrom: fieldRef: fieldPath: status.podIP - name: MY_POD_NAME valueFrom: fieldRef: fieldPath: metadata.name - name: DNS_DOMAIN_NAME value: "wls-subdomain" - name: WLUSER valueFrom: secretKeyRef: name: wlsecret key: username - name: WLPASSWORD valueFrom: secretKeyRef: name: wlsecret key: password volumeMounts: - mountPath: /u01/wlsdomain name: domain-home - mountPath: /u01/filestores name: filestore-data volumes: - name: domain-home persistentVolumeClaim: claimName: wlserver-pvc-1 - name: filestore-data persistentVolumeClaim: claimName: wlserver-pvc-2 --- apiVersion: v1 # headless service required for statefulSet kind: Service metadata: name: wls-subdomain labels: app: managed-server spec: ports: - name: client port: 8011 protocol: TCP targetPort: 8011 clusterIP: None selector: app: managed-server --- apiVersion: v1 kind: Service metadata: name: wls-service labels: app: managed-server spec: type: NodePort ports: - name: client port: 8011 protocol: TCP targetPort: 8011 nodePort: 30009 selector: app: managed-server
修改k8s/pv.yml
kind: PersistentVolume apiVersion: v1 metadata: name: pv1 labels: app: wls-domain spec: storageClassName: manual capacity: storage: 10Gi accessModes: - ReadWriteMany persistentVolumeReclaimPolicy: Recycle # Retain, Recycle, Delete hostPath: #path填上本地目录 path: "/home/oracle/pv/pv1" #nfs: #server:#path: --- kind: PersistentVolume apiVersion: v1 metadata: name: pv2 labels: app: wls-domain spec: storageClassName: manual capacity: storage: 10Gi accessModes: - ReadWriteMany persistentVolumeReclaimPolicy: Recycle # Retain, Recycle, Delete hostPath: path: "/home/oracle/pv/pv2" #nfs: #server: #path: --- kind: PersistentVolume apiVersion: v1 metadata: name: pv3 labels: app: wls-domain spec: storageClassName: manual capacity: storage: 10Gi accessModes: - ReadWriteOnce persistentVolumeReclaimPolicy: Recycle # Retain, Recycle, Delete hostPath: path: "/home/oracle/pv/pv3" #nfs: #server: #path:
NOTE:hostPath下所填的目录需有777权限。
IMPORTANT：在执行创建脚本之前，必须确保有一个用户的UID和GID为1000:1000。
然后，依次执行以下命令：
$ kubectl create -f k8s/secrets.yml $ kubectl create -f k8s/pv.yml $ kubectl create -f k8s/pvc.yml $ kubectl create -f k8s/wls-admin.yml $ kubectl create -f k8s/wls-stateful.yml
至此，一个带有两个managed-server的domain便创建好了。
$ kubectl get all NAME READY STATUS RESTARTS AGE po/admin-server-1238998015-f932w 1/1 Running 0 11m po/managed-server-0 1/1 Running 0 11m po/managed-server-1 1/1 Running 0 8m NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE svc/admin-server 10.102.160.1238001:30007/TCP 11m svc/kubernetes 10.96.0.1 443/TCP 39d svc/wls-service 10.96.37.152 8011:30009/TCP 11m svc/wls-subdomain None 8011/TCP 11m NAME DESIRED CURRENT AGE statefulsets/managed-server 2 2 11m NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE deploy/admin-server 1 1 1 1 11m NAME DESIRED CURRENT READY AGE rs/admin-server-1238998015 1 1 1 11m
现在可以登录http:IP:30007/console访问控制台，默认账号为：weblogic，密码为：weblogic1。
在weblogic中部署的应用访问端口为30009。
改进
我们可以制作chart来一键安装，步骤如下：
1.创建名为hello-world的charts
helm create weblogic
2.将k8s/目录放入weblogic/templates目录下
注：helloworld程序简单，程序不需引入相关依赖，也不需要传入参数。charts提供了版本控制，引入依赖，传参等配置文件。
3.打包tar
helm package weblogic
4.在本地创建charts文件夹，并将打包的tar文件移入，生成index.yaml
mv weblogic-0.1.0.tgz charts/
helm serve --repo-path ./charts
5、安装chart
helm install weblogic
