镜像构建交付和使用Rancher进行容器创建管理(4)

1.1准备集中配置项目alaxiaoyou-config-service-0.0.1-SNAPSHOT.jar包，gitlab仓库中。
创建config-service构建build目录

mkdir -p /data/httpd/ms-config-service-tmp -rw-r--r-- 1 root root 276 Jan 14 17:34 dockerfile drwxr-xr-x 2 root root 58 Jan 14 17:31 target

1.2 编写dockfile
cat /data/httpd/ms-config-service-tmp/dockerfile

FROM ms/jdk1.8:v1 MAINTAINER tmp-config-service "name@alaxiaoyou.com" RUN mkdir -p /data/httpd/ ADD target/alaxiaoyou-config-service-0.0.1-SNAPSHOT.jar /data/httpd/ WORKDIR /data/httpd/ ENTRYPOINT java -Xmx128m -Xss512k -jar alaxiaoyou-config-service-0.0.1-SNAPSHOT.jar

说明：ENTRYPOINT进入容器中执行此jar包。

1.3 构建，镜像

docker build -t ms/config-service . Sending build context to Docker daemon 21.2MB Step 1/6 : FROM ms/jdk1.8:v1 ---> 00d3c71ae0be Step 2/6 : MAINTAINER tmp-config-service "yuhuanghui@alaxiaoyou.com" ---> Running in a3e0038610ff ---> 75d7642e16ec Removing intermediate container a3e0038610ff Step 3/6 : RUN mkdir -p /data/httpd/ ---> Running in 4b1ff33f58df ---> f43b916f6835 Removing intermediate container 4b1ff33f58df Step 4/6 : ADD target/alaxiaoyou-config-service-0.0.1-SNAPSHOT.jar /data/httpd/ ---> 99608e52e219 Removing intermediate container 0bd4d9130dd0 Step 5/6 : WORKDIR /data/httpd/ ---> 656a442c7ac2 Removing intermediate container d18fbdc1c6a6 Step 6/6 : ENTRYPOINT java -Xmx128m -Xss512k -jar alaxiaoyou-config-service-0.0.1-SNAPSHOT.jar ---> Running in 0371f9addb5d ---> c7375c40286e Removing intermediate container 0371f9addb5d Successfully built c7375c40286e Successfully tagged ms/config-service:latest [root@rancher-qa ms-config-service-tmp]# pwd /data/httpd/ms-config-service-tmp [root@rancher-qa ms-config-service-tmp]# docker images | grep config ms/config-service latest c7375c40286e 2 minutes ago 530MB registry.cn-hangzhou.aliyuncs.com/xmbaby-pre/ms-config latest 51a4521d7581 24 months ago 578MB

1.4 登录阿里云容器镜像服务
创建镜像本地仓库名称tmp-config-service-ms

1.5 镜像push到阿里云Docker Registry
切换到rancher/server
登录到阿里云Docker Registry
登录Docker Registry -> 打tag -> push到Docker Registry

至此，tmp-config-service-ms镜像交付完成。

tmp-config-service-ms镜像启动，统一用rancher编排UI工具来启动。
tmp-config-service-ms服务启动需依赖宿主机的目录，这个目录，是本地git仓库项目，gitlab中为：git@xxxx.git。provider配置修改，都通过gitlab进行修改，会进行更新到本地目录中，重启此provider即可生效。

2.1 启动tmp-config-service-ms服务，rancher中操作。
创建服务tmp-config-service-ms：
