HyperKit VM
helloworld
docker --version
docker-compose --version
docker-machine --version
docker ps
docker run hello-world
docker run -d -p 80:80 --name webserver nginx
docker run -it ubuntu bash
docker run docker/whalesay cowsay boo
docker run docker/whalesay cowsay boo-boo
build image
vi Dockerfile
FROM docker/whalesay:latest
RUN apt-get -y update && apt-get install -y fortunes
CMD /usr/games/fortune -a | cowsay
docker build -t docker-whale .
docker images
docker run docker-whale
tag & push
docker tag 038cc8845778 bluexiii/docker-whale:latest
docker login
docker push maryatdocker/docker-whale
docker rmi -f docker-whale
docker run bluexiii/docker-whale
容器命名
docker run --name bob_the_container -i -t ubuntu /bin/bash
重新启动已停止的容器
docker start bob_the_container
附着到容器上
docker attach bob_the_container
创建守护式容器
docker run --name daemon_dave -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1;done"
查看日志
docker logs -ft daemon_dave
查看容器中的进程
docker top daemon_dave
查看统计信息
docker stats daemon_dave
停止守护式容器
docker stop daemon_dave
自动重启容器
--restart=always
--restart=on-failure:5
docker run --restart=always --name daemon_dave2 -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1;done"
获取容器详情
docker inspect daemon_dave2
删除容器
docker rm
删除所有容器
docker rm docker ps -a -q
本地镜像位置
$HOME/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2
拉取镜像到本机
docker pull fedora
查找镜像
docker search fedora
构建镜像
使用commit构建镜像
基于Ubuntu构建
docker run -i -t ubuntu /bin/bash
内网环境下设置apt代理
cat > /etc/apt/apt.conf.d/10proxy
Acquire::http::Proxy "http://134.32.32.13:31315/";
^d
安装基础包
apt update
apt install nginx
commit提交
docker commit cb051b49a4cd bluexiii/mynginx
or
docker commit -m 'message' -a 'author' cb051b49a4cd bluexiii/mynginx:tag
类似git，只提交差异部分，速度很快
docker inspect bluexiii/mynginx
使用Dockfile构建镜像
vi Dockerfile
FROM ubuntu
RUN echo 'Acquire::http::Proxy "http://IP:PORT/";' > /etc/apt/apt.conf.d/10proxy
RUN apt-get -y update && apt-get install -y nginx
RUN echo 'hello world' > /usr/share/nginx/html/index.html
EXPOSE 80
docker build -t bluexiii/mynginx2 .
运行镜像
docker run -d -p 40080:80 --name mynginx2 bluexiii/mynginx2 nginx -g "daemon off;"
查看端口映射情况
docker port mynginx2 80
