环境:OCP 3.4
1. 复制 Spring Boot builder 镜像 (在 MAC 机器上操作)
docker save -o spring-boot-rhel7.tar.gz maping930883/spring-boot-rhel7:latest
scp spring-boot-rhel7.tar.gz root@192.168.56.112:/opt/ose/images/
2. 修改 Tag,并 Push 到本地镜像仓库 (在 Registry 机器上操作)
cd /opt/ose/images
docker load -i spring-boot-rhel7.tar.gz
docker tag maping930883/spring-boot-rhel7:latest registry.example.com:5000/maping930883/spring-boot-rhel7:latest
docker push registry.example.com:5000/maping930883/spring-boot-rhel7:latest
3. 克隆 springboot-sample-app 到本地 (在 MAC 机器上操作)
cd ~/mygit
git clone https://github.com/codecentric/springboot-sample-app.git
scp -r springboot-sample-app/ root@192.168.56.112:/opt/
4. 初始化 springboot-sample-app git 仓库(在 Registry 机器上操作)
mkdir -p /opt/git/repo/springboot-sample-app.git;
cd /opt/git/repo/springboot-sample-app.git;
git init --bare;
git update-server-info;
mv hooks/post-update.sample hooks/post-update;
5. 拷贝 springboot-sample-app 代码,并提交(在 Registry 机器上操作)
cd /opt
mv springboot-sample-app springboot-sample-app-demo
git clone file:///opt/git/repo/springboot-sample-app.git/
cp springboot-sample-app-demo/* springboot-sample-app -rf;
cp springboot-sample-app-demo/.sti springboot-sample-app -rf;
cp springboot-sample-app-demo/.htaccess springboot-sample-app -rf;
cp springboot-sample-app-demo/.gitignore springboot-sample-app -rf;
cd springboot-sample-app;
git add .;
git commit -m 'initial upload';
git push origin master;
6. 验证 springboot-sample-app git 仓库是否创建成功(在 Master 机器上操作)
cd /tmp
git clone http://git.example.com/git/springboot-sample-app.git/
7. 首次部署 springboot-sample-app 应用 (在 Master 机器上操作)
docker pull registry.example.com:5000/maping930883/spring-boot-rhel7
oc new-app registry.example.com:5000/maping930883/spring-boot-rhel7~http://git.example.com/git/springboot-sample-app.git
本来想先生成应用,然后根据自动创建 IS 和其它资源,导出 template 大致的样子再修改,
但是报告如下错误:
Cloning "http://git.example.com/git/springboot-sample-app.git" ...
error: build error: fatal: dumb http transport does not support --depth
估计是因为我的 git 仓库不是真正的 git server。
只好手工创建 template 啦。
8. 创建 Image Stream (在 Master 机器上操作)
oc create -f spring-boot-rhel7-is.json -n openshift
其中 spring-boot-rhel7-is.json 内容如下:
{
"kind": "ImageStream",
"apiVersion": "v1",
"metadata": {
"name": "spring-boot-rhel7",
"creationTimestamp": null
},
"spec": {
"dockerImageRepository": "registry.example.com:5000/maping930883/spring-boot-rhel7",
"tags": [
{
"name": "latest",
"annotations": null,
"from": {
"kind": "DockerImage",
"name": "registry.example.com:5000/maping930883/spring-boot-rhel7"
},
"generation": 1,
"importPolicy": {
"insecure": true
}
}
]
}
}
确认 TAGS 已经打上,执行 oc get is spring-boot-rhel7 -n openshift
输出如下:
NAME DOCKER REPO TAGS UPDATED
spring-boot-rhel7 registry.example.com:5000/maping930883/spring-boot-rhel7 latest 2 seconds ago
9. 创建 Template
oc create -f spring-boot-rhel7-s2i-template.json -n openshift
其中 spring-boot-rhel7-s2i-template.json 内容如下:

10. 选择 spring-boot-rhel7-s2i 模板,发布应用
经过前面的“艰苦努力”,现在发布 Spring Boot 应用变得超级简单!
11. 清理并重做
