容器化配置生成神器

# 安装 derrick$ pip install python-derrick
# 报 fatal error: Python.h: No such file or directory 错误，请安装下面包(CentOS 例子)$ yum install -y python-devel

# 下载 derrick-nodejs-demo node 项目$ git clone https://github.com/ringtail/derrick-nodejs-demo
# 选择需要部署的平台，支持 Kubernetes 和 Swarm# 因机器上没有安装 Kubernetes，这里选择 Swarm$ derrick config
? Which Orchestration Engine would you like to choose?  Swarm
# 运行 Derrick$ derrick init 
? Please input image name with tag (such as "registry.com/user/repo:tag"):  yangpeng2468/test:v3
Derrick detect your platform is NodeJs and compile successfully.
# 查看生成的配置$ git status
# 位于分支 master# 未跟踪的文件:#   （使用 "git add <file>..." 以包含要提交的内容）##	.dockerignore#	Dockerfile#	Jenkinsfile#	derrick_conf#	docker-compose.yml#	kubernetes-deployment.yaml提交为空，但是存在尚未跟踪的文件（使用 "git add" 建立跟踪）

# 本地验证容器化结果 $ derrick up
