篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了docker,k8s部署Apollo相关的知识，希望对你有一定的参考价值。

因为楼主更改了apollo源码，所以需要重新打包，然后在制作镜像。

1.docker部署Apollo

1. 打包

可以参考上文。

2.制作镜像

1.获取zip包

分别获取打包之后zip包，在/apollo-portal/target/，apollo-adminservice/target/，apollo-configservice/target/中。

2.获取dockerflie

分别在apollo-portal，apollo-adminservice，apollo-configservice中获取dockerflie。

3.将以上两个文件分别放于任意文件夹中并分别执行

docker build -t apollo-portal .
docker build -t apollo-adminservice .
docker build -t apollo-configservice .

3.运行容器

在虚拟机中执行以下命令即可。

adminconfig
docker run -d -p 8090:8090 --net=host -e SPRING_DATASOURCE_URL="jdbc:postgresql://ip:5432/apolloconfig?characterEncoding=utf8" -e SPRING_DATASOURCE_USERNAME=apolloconfig -e SPRING_DATASOURCE_PASSWORD=123  -d -v /tmp/logs:/opt/logs --name apollo-adminservice apollo-adminservice

SPRING_DATASOURCE_URL: 对应环境ApolloConfigDB的地址
SPRING_DATASOURCE_USERNAME: 对应环境ApolloConfigDB的用户名
SPRING_DATASOURCE_PASSWORD: 对应环境ApolloConfigDB的密码
--name apollo-adminservice apollo-adminservice：为镜像同名 下面同理

apollo-configservice 
docker run -p 8080:8080 --net=host -e SPRING_DATASOURCE_URL="jdbc:postgresql://ip:5432/apolloconfig?characterEncoding=utf8"  -e SPRING_DATASOURCE_USERNAME=apolloconfig -e SPRING_DATASOURCE_PASSWORD=123  -d -v /tmp/logs:/opt/logs --name apollo-configservice apollo-configservice

SPRING_DATASOURCE_URL: 对应环境ApolloConfigDB的地址
SPRING_DATASOURCE_USERNAME: 对应环境ApolloConfigDB的用户名
SPRING_DATASOURCE_PASSWORD: 对应环境ApolloConfigDB的密码

apollo-portal
docker run -p 8070:8070 --net=host -e SPRING_DATASOURCE_URL="jdbc:postgresql://ip:5432/apolloportal"  -e SPRING_DATASOURCE_USERNAME=apolloportal -e SPRING_DATASOURCE_PASSWORD=123 -e APOLLO_PORTAL_ENVS=dev  -e DEV_META=http://localhost:8080 -d -v /tmp/logs:/opt/logs --name apollo-portal apollo-portal

SPRING_DATASOURCE_URL: 对应环境ApolloPortalDB的地址
SPRING_DATASOURCE_USERNAME: 对应环境ApolloPortalDB的用户名
SPRING_DATASOURCE_PASSWORD: 对应环境ApolloPortalDB的密码
APOLLO_PORTAL_ENVS(可选): 对应ApolloPortalDB中的apollo.portal.envs配置项，如果没有在数据库中配置的话，可以通过此环境参数配置
DEV_META/PRO_META(可选): 配置对应环境的Meta Service地址，以$ENV_META命名，需要注意的是如果配置了ApolloPortalDB中的apollo.portal.meta.servers配置，则以apollo.portal.meta.servers中的配置为准

如没有定制数据库需求，可以参考官方文档
https://github.com/ctripcorp/apollo/wiki/%E5%88%86%E5%B8%83%E5%BC%8F%E9%83%A8%E7%BD%B2%E6%8C%87%E5%8D%97#2-apolloportalmetaservers—%E5%90%84%E7%8E%AF%E5%A2%83meta-service%E5%88%97%E8%A1%A8

2.k8s部署Apollo

书接上文楼主定制了oracle版本的apollo，那么怎么使用k8s部署呢，本文只部署dev环境，使用yaml文件在Kubernetes-dashboard部署。

如果有对Kubernetes-dashboard不熟悉的，可以参考k8s专栏。

1.部署apollo-admin

注意：以上yaml 一定注意格式，比如空行，空格，注释，能去掉一定去掉，否则会报各种错误。

注意，以下apollo-portal.zip中的配置也需要修改（否则一直会访问localhost）
