Docker

安裝

https://docs.docker.com/installation

1. install visualbox
2. brew install docker boot2docker

基本命令

https://docs.docker.com/reference/commandline/cli/ https://docs.docker.com/reference/run/

1. 启动 boot2docker: init && boot2docker up
2. 更新 boot2docker: download
3. 查看所有的images: docker images
4. 下载image: docker pull centos:centos6
5. 运行一个container: docker run -t -i centos /bin/bash
6. 后台运行一个container: docker -d run centos xxx
7. 端口映射到本地(OSX需要用VisualBox做，详见14)�: docker -d -p 10010:10010 centos webapp
8. 查看所有container: docker ps -a
9. 启动/停止一个container: docker start/stop container_id
10. 删除一个container: docker rm container_id
11. 删除一个image: docker rmi image_id
12. 通过Dockerfile创建一个image:https://docs.docker.com/reference/builder/
13. commit container 到image: docker commit -m 'update' -a 'author' container_id image_id/image_name
14. Mac下端口映射: VBoxManage controlvm boot2docker-vm natpf1 "ssdb,tcp,127.0.0.1,8888,,8888"

进阶用法

1. 绑定多了个container，组合成一个新的架构:

sudo docker run --name redis -d xiocode/redis
sudo docker run --link redis:db --name web -i -t ubuntu:12.10 /bin/bash
$ env | grep DB_
Should return something similar to this with your values

DB_NAME=/violet_wolf/db
DB_PORT_6379_TCP_PORT=6379
DB_PORT=tcp://172.17.0.33:6379
DB_PORT_6379_TCP=tcp://172.17.0.33:6379
DB_PORT_6379_TCP_ADDR=172.17.0.33
DB_PORT_6379_TCP_PROTO=tcp

$ redis-cli -h $DB_PORT_6379_TCP_ADDR
$ redis 172.17.0.33:6379>

....

用Docker運行Golang編譯本地代碼
docker run --rm -v /home/core/flannel:/opt/flannel -i -t google/golang /bin/bash -c "cd /opt/flannel && ./build"

安裝容器名啓動已關閉的容器
docker ps -a | grep 'container_name' | awk '{print $1}' | xargs docker start
