docker run ############### Usage:: # 在一新的container中运行一新的命令 docker run [OPTIONS] IMAGE [COMMAND] [ARG...] 常用命令:: -p, --publish list 将容器端口映射为宿主机端口 -P, --publish-all 将所有exposed的端口映射为宿主机上的随机端口 -d, --detach 后台运行 --name string 为container赋值名 -u, --user string 指定用户 -i: --interactive -t: --tty -v, --volume list Bind mount a volume, 例: -v : -w, --workdir string Working directory inside the container --log-opt max-size=100m 常用实例 ======== :: # 执行docker命令 $ docker run ubuntu:14.04 /bin/cat /etc/issue -p, --publish list指定端口:: 1. 将容器内的80端口绑定到本地宿主机的80端口上 $ docker run -d -p 127.0.0.1:80:80 --name static_web test/static_web nginx -g "daemon off;" 2. udp模式 $ sudo docker run -d -p 127.0.0.1:5000:5000/udp training/webapp python app.py 3. 可以使用类似的方法将容器内的80端口绑定到一个特定网络接口的随机端口上: # docker run -d -p 127.0.0.1::80 --name static_web test/static_web nginx -g "daemon off;" 4. 容器启动绑定多IP $ docker run -d -p 5005:5000 -p 5006:80 myfirstapp python app.py #容器ID:44e703c1279a $ docker port 44e703c1279a 5000/tcp -> 0.0.0.0:5005 80/tcp -> 0.0.0.0:5006 -P, --publish-all:: # 该命令会将容器内的80端口对本地宿主机公开，并且绑定到宿主机的一个随机端口上 $ docker run -d -P --name static_web test/static_web nginx -g "daemon off;" -it:: // -i: --interactive // -t: --tty # 需要在运行时指定: --name jenkins-tutorials $ docker exec -it jenkins-tutorials bash $ docker run -t -i ubuntu:14.04 /bin/bash # shell登陆 -t(--tty=true) and -i(--interactive=true) --link list:: # 创建一个名为web的container链接到名为db的container # --link :: # : 为要被链接的container的name # : 是这个的别名 $ docker run -d -P --name web --link db:db training/webapp python app.py -v, --volume list:: # list是指: -v可以被多次使用 $ docker run -d -P --name web -v /webapp training/webapp python app.py $ docker run -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins # Mount a Host Directory as a Data Volume $ docker run -d -P --name web -v /src/webapp:/opt/webapp training/webapp python app.py # 新建一个read-only类型的volume: $ docker run -d -P --name web -v /src/webapp:/opt/webapp:ro training/webapp python app.py -d, --detach:: $ docker run -d ubuntu:14.04 /bin/sh -c "while true; do echo hello world; sleep 1; done" 1e5535038e285177d5214659a068137486f96ee5c2e85a4ac52dc83f2ebe4147
