docker草稿

基本组成

• Docker Image 镜像
• Docker Container容器
• Docker Registry仓库

基本操作

• docker version
• docker search tutorial
• docker pull learn/tutorial
• docker run learn/tutorial echo 'hello world'
• docker run learn/tutorial apt-get install -y ping
• docker ps -l
• docker commit b5533536a433 learn/ping
• docker run learn/ping ping www.baidu.com
• docker ps
• docker inspect b5533536a433
• docker push learn/ping

交互容器

• docker run -it ubuntu bash
• docker run --name=container01 -it ubuntu bash
• docker inspect container01
• docker start -i container01
• docker rm container01

守护容器

• docker run -it ubuntu bash

# 退出
ctrl+p ctrl+q

• docker ps
• docker attach zealous_margulis
• docker logs -tf --tail 10 container01
• docker top container01
• docker exec -i -t container01 bash
• docker stop determined_shirley
• docker kill cocky_hoover

部署网站

• docker run -p 80 --name web -it ubuntu bash
• apt-get update
• apt-get install nginx -y
• apt-get install vim
• mkdir -p /var/www/html
• whereis nginx
• vim /etc/nginx/nginx/sites-enabled/default
• nginx
• ps -ef
• ctrl+p ctrl+q
• docker ps
• docker port web
• docker top web
• curl http://127.0.0.1:49167
• docker inspect container01
• docker stop web
• docker start -i web
• docker exec web nginx #启动nginx
• docker top web
• 端口会变

查看和删除镜像

• 列出镜像

docker images 
docker images --no-trunc
docker rmi ubuntu:14.04
docker rmi $(docker images ubuntu -q)

获取推送镜像

• registry.hub.docker.com

docker search ubuntu
docker pull ubuntu:14.04
docker push dormancypress/nginx

构建docker镜像

• 通过容器

docker commit
docker build(dockerfile)

docker run -it -p 80 --name commit_test ubuntu bash
apt-get update
apt-get install nginx
docker ps -l
docker commit -a 'cwydocker' -m 'nginx' commit_test cwydocker/commit_test1
docker images
docker run -d --name nginx_web1 cwydocker/commit_test1 nginx -g "daemon off;"
curl http://127.0.0.1
docker run -d --name nginx_web2 -p 80 cwydocker/commit_test1 nginx -g "daemon off;"
docker ps
curl http://127.0.0.1:49155

• dockerfile 文件构建

mkdir -p dockerfile/df_test1
vim df_test1
---------------------
# First dockerfile for test
FROM ubuntu:14.04
MAINTAINER cwydocker
RUN apt-get update
RUN apt-get install -y nginx
EXPOSE 80
-------------------------------------
docker build -t='cwydocker/df_test1' .
