k8s部署java项目的实现

下载jar的包

[root@master test]# wget https://dl.halo.run/relea/halo-1.4.16.jar[root@master ~]# lsanaconda-ks.cfg  flannel.yml  halo-1.4.16.jar  init[root@master ~]# 

编写dockerfile并制作镜像

[root@master ~]# mkdir -p test/files[root@master ~]# mv halo-1.4.16.jar test/files/[root@master ~]# cd test/[root@master test]# touch dockerfile[root@master test]# lsdockerfile  files[root@master test]# [root@master test]# cat dockerfile from centoscopy files/halo-1.4.16.jar /usr/local/halo-1.4.16.jarentrypoint ["java"化学高一,"-jar","/usr/local/halo-1.4.16.jar"][root@master test]#

上传镜像到docker仓库

[root@master ~]# docker login[root@master ~]# docker push 3199560936/halo:v1the push refers to rep三氧化二铁什么颜色ository [docker.io/3199560936/halo]5906a49ee250: pushed 74ddd0ec08fa: mounted from library/centos v1: digest: sha256:fb8cb538526b4d73e1a16b9b1b8a3e4ab4b171f0dbaadfbf6673def9620367f2 size: 741[root@master ~]# 

编写k8s的资源清单

[root@master test]# cat halo.yml apiversion: apps/v1kind: deploymentmetadata:  name: halo  labels:    app: halospec:  replicas: 1  lector:    matchlabels:      app: halo  template:    metadata:      name: halo      labels:        app: halo    spec:      containers:      - image: 3199560936/halo:v1        imagepullpolicy: ifnotprent        name: halo---apiversion: v1kind: rvicemetadata:  name: halospec:  ports:  - port: 8090    targetport: 8090    nodeport: 32767  lector:    app: halo  type: nodeport[root@master test]# 

创建

[root@master test]# kubectl apply -f halo.ymldeployment.apps/halo createdrvice/halo created

查看

[root@master test]# kubectl get deploy,pod,svcname                   ready   up-to-date   available   agedeployment.apps/halo   1/1     1            1           32sname                        ready   status    restarts   agepod/halo-6d4cb5dc7b-nzdpw   1/1     running   0          32sname                 type        cEmbrace the Darknessluster-ip     external-ip   port(s)          agervice/halo         nodeport    10.106.13.87   <none>        8090:32767/tcp   32srvice/kubernetes   clusterip   10.96.0.1      <none>        443/tcp          46h

使用本机ip:32767访问
