2.1.1 导入db相关的数据

# cd apollo/scripts/apollo-on-kubernetes/db/
# mysql -h127.0.0.1 -uroot -ppassword -P30100 < config-db-dev/apolloconfigdb.sql
# mysql -h127.0.0.1 -uroot -ppassword -P30101 < config-db-test-beta/apolloconfigdb.sql 
# mysql -h127.0.0.1 -uroot -ppassword -P30102 < config-db-prod/apolloconfigdb.sql
# mysql -h127.0.0.1 -uroot -ppassword -P30103 < portal-db/apolloconfigdb.sql

2. 构建镜像

https://github.com/ctripcorp/apollo/releases # 找到3个包

技术图片

# wget https://github.com/ctripcorp/apollo/releases/download/v1.3.0/apollo-adminservice-1.3.0-github.zip
# wget https://github.com/ctripcorp/apollo/releases/download/v1.3.0/apollo-configservice-1.3.0-github.zip
# wget https://github.com/ctripcorp/apollo/releases/download/v1.3.0/apollo-portal-1.3.0-github.zip

2.1 # 解压3个包相关的 jar 命名为
apollo-adminservice.jar
apollo-configservice.jar
apollo-portal.jar

jar包移动对应的目录 apollo-admin-server apollo-config-server apollo-portal-server

vim apollo-admin-server/Dockerfile //注释一行避免文件configmap只读 3个Dockerfile都需要修改

vim apollo-config-server/Dockerfile

vim apollo-portal-server/Dockerfile

#ENTRYPOINT ["/apollo-admin-server/entrypoint.sh"]

2.2 build相关的镜像

# cd apollo/scripts/apollo-on-kubernetes/alpine-bash-3.8-image
# docker build -t apollo:alpine-bash-3.8 .
# docker push apollo:alpine-bash-3.8

# cd apollo/scripts/apollo-on-kubernetes/apollo-admin-server
# docker build -t apollo:apollo-admin-server-v1.3.0 .
# docker push apollo:apollo-admin-server-v1.3.0

# cd apollo/scripts/apollo-on-kubernetes/apollo-config-server
# docker build -t apollo:apollo-config-server-v1.3.0 .
# docker push  apollo:apollo-config-server-v1.3.0

# cd  apollo-portal-server
# docker build -t apollo:apollo-portal-server-v1.3.0 
# docker push apollo:apollo-portal-server-v1.3.0

3. 修改配置文件

打开portal 入口
http://127.0.0.1:30110/ # 查看是否正常
默认账号密码: apollo admin

如果需要外部访问的话就需要添加对外服务的配置

admin和config都需要配置启动参数

        - name: JAVA_OPTS
          value: "-Dapollo.configService=http://127.0.0.1:30002 -Deureka.instance.homePageUrl=http://127.0.0.1:30002"

流程图

mkdir -p /data/apollo/mysql-apollo-prd /data/apollo/mysql-apollo-test /data/apollo/mysql-apollo-dev /data/apollo/mysql-apollo-portal // nfs服务端创建文件夹

kubectl apply -f mysql-apollo-dev.yml # 开发 db

kubectl apply -f mysql-apollo-test.yml //测试 db

kubectl apply -f mysql-apollo-prd.yml // 生产 db

kubectl apply -f mysql-apollo-portal.yml // 入口 db

2.1.1 导入db相关的数据

2. 构建镜像

vim apollo-admin-server/Dockerfile //注释一行 避免文件configmap只读 3个Dockerfile都需要修改

vim apollo-config-server/Dockerfile

vim apollo-portal-server/Dockerfile

3. 修改配置文件

cd apollo/scripts/apollo-on-kubernetes/kubernetes

3.1 dev

kubectl apply -f apollo-env-dev/service-apollo-admin-server-dev.yaml

kubectl apply -f apollo-env-dev/service-apollo-config-server-dev.yaml

kubectl apply -f apollo-env-test-beta/service-apollo-admin-server-test-beta.yaml

kubectl apply -f apollo-env-prod/service-apollo-admin-server-prod.yaml

kubectl apply -f service-apollo-portal-server.yaml

如果需要外部访问的话就需要添加对外服务的配置

vim apollo-admin-server/Dockerfile //注释一行避免文件configmap只读 3个Dockerfile都需要修改
