常用命令

# 从当前目录中找dockerfile构建image
docker build -t imagename .
启动 停止 重启 删除
docker run -d -p 80:8888 --name mycontainer myimage

docker stop mycontainer

docker restart mycontainer

docker stop mycontainer

docker rm mycontainer
登录到一个在running的container中
docker exec -it mycontainer bash
volumn挂载
将docker中的/var/log/jackyang.me目录对应成本机上的/Users/Jack
docker run ... -v /Users/Jack:/var/log/jackyang.me
container sync time with host
docker run ... -v /etc/localtime:/etc/localtime:ro

docker + node.js + pm2

docker中使用pm2，Dockerfile
(经测试，pm2在遇到异常时的重启反应比forever好很多，forever经常在连续错误时无法重启)

FROM hub.c.163.com/library/node:latest
Create app directory
RUN mkdir -p /home/app

WORKDIR /home/app
Bundle app source
COPY . /home/app

RUN npm install --production

RUN npm install -g pm2
ENV NODE_ENV=production
EXPOSE 8080

CMD ["pm2-docker","./src/app.js"]

一个简单的部署docker的脚本

# pull latest code 
git pull origin master
stop container
docker stop demo-service
remove container
docker rm demo-service
build and replace image
docker build -t demo-service .
run a container
docker run -d -p 8080:8080 -v /var/log:/var/log --name demo-service demo-service
