构建一个 预装 pm2 的 node 项目 docker 底包

Dockerfile: 创建 dockerfile 文件， 命名为 dockerfile-yourProject-node.8.12.0-pm2

# MAGE:     yourGroup/yourProject-node.8.12.0-pm2
# VERSION:  1.0.0
# AUTHOR:   ecalf

# 基于网上公开的 docker 镜像构建，根据你的需要到 hub.docker.com 上找对应的镜像
FROM mhart/alpine-node:8

创建文件夹， 把 dockerfile-yourProject-node.8.12.0-pm2 放进文件夹内，在命令行进入 该文件夹，执行下面命令构建底包，不要 在包含很多额外文件的文件夹内打包，否则准备docker上下文环境会花掉很长时间。

docker build -t hub.docker.xxx.com/yourGroup/yourProject-node.8.12.0-pm2:1.0.0 -f dockerfile-yourProject-node.8.12.0-pm2 .

 

 

构建项目的 Dockerfile 文件， 一个例子，具体根据自己项目具体情况来编写 

# MAGE:     yourGroup/yourProject
# VERSION:  5.8.0

CMD ["pm2-docker", "start", "/home/project/www.xxx.com/process.json"]

 

 

项目镜像打包命令， 从命令传入新镜像的 tag，脚本 命名为 buildDocker， 则执行  buildDocker 1.0.0

#!/bin/sh

tag=$1
if [ 'n'$1 = 'n' ]; then
    echo 'please input tag as argument'
else
    sudo docker build -t hub.docker.xxx.com/yourGroup/yourProject:${tag} .
fi

 

项目镜像的启动，从命令行传入要启动的镜像 tag,脚本 命名为 runDocker， 则执行  runDocker 1.0.0, 例子中设置了 环境配置文件夹、日志文件夹 的 挂载 

#!/bin/sh

tag=$1
sudo docker run --name yourProject -p 14305:4305 -v /home/ecalf/work/docker/yourProject/config:/home/project/www.xxx.com/confLocal  -v /home/ecalf/work/docker/yourProject/logs:/home/project/www.xxx.com/logs -v /home/ecalf/work/docker/yourProject/log:/data/log -d hub.docker.xxx.com/yourGroup/yourProject:${tag}
