实战项目部署应用到kubernetes流程(jenkins+docker+k8s)

通过jenkins构建java应用程序发布到k8s集群中

本文已一个大数据的java项目来演示构建部署过程

支持发布和回滚

支持一套模板应用不同项目

 

k8s基础准备

创建项目名称空间

[root@k8s-master ~]# kubectl create ns architect
namespace/architect created

[root@k8s-master ~]# kubectl label namespace architect istio-injection=enabled
namespace/architect labeled
[root@k8s-master ~]# kubectl get namespace -L istio-injection
NAME           STATUS   AGE     ISTIO-INJECTION
architect      Active   87s     enabled
default        Active   39d     enabled
istio-system   Active   7d17h   
kube-public    Active   39d     
kube-system    Active   39d     
[root@k8s-master ~]# 

　　

创建全局配置文件

＃创建大数据配置文件
[root@k8s-master ~]# ls bigdata-counter
core-site.xml  dmp_operator1.keytab  hbase-site.xml  hdfs-site.xml  krb5.conf
[root@k8s-master ~]#
[root@k8s-master ~]# kubectl create configmap bigdata-config --from-file=/root/bigdata-counter/ -n architect 
configmap/bigdata-config created
[root@k8s-master ~]# 
#全局环境变量
[root@k8s-master ~]# cat yaml/global-config.yaml 
apiVersion: v1
kind: ConfigMap
metadata:
  name: global-config
  namespace: architect
data:
  CONFIG_SERVER_URL: http://config.ms.xx.com
  CONFIG_SERVER_USER: myconfig
  ILOG_BOOTSTRAP_SERVERS: bootstrap.servers=192.168.1.122:9092
  CONFIG_SERVER_PWDS: mc123456

[root@k8s-master ~]# 
[root@k8s-master ~]# kubectl apply -f yaml/global-config.yaml 
configmap/global-config created
[root@k8s-master ~]# kubectl get configmap -n architect
NAME DATA AGE
bigdata-config 4 2m33s
global-config 4 3s
[root@k8s-master ~]#
