Docker、Laradock命令

Docker常用命令

#使用docker：
systemctl start/stop/restart/status docker
sudo service docker start/stop/restart/status
systemctl enable docker        #开机启动
sudo systemctl daemon-reload   #守护进程重启 

#镜像
docker images / docker image ls #列出本地镜像
docker rmi training/sinatra #删除（在删除镜像之前要先用 docker rm 删掉依赖于这个镜像的所有容器）
docker run -t -i ubuntu:14.04 /bin/bash #
【docker run -ti --name myubuntu -d ubuntu】{创建一个名为myubuntu的容器：ubuntu为REPOSITORY不加tag}
docker commit -m "Added json gem" -a "Docker Newbee" 0b2616b0e5a8 ouruser/sinatra:v2 #更新镜像 
【其中，-m 来指定提交的说明信息，跟我们使用的版本控制工具一样；-a 可以指定更新的用户信息；之后是用来创建镜像的容器的 ID；最后指定目标镜像的仓库名和 tag 信息。创建成功后会返回这个镜像的 ID 信息。】
docker tag 5db5f8471261 ouruser/sinatra:devel #修改标签
docker build ${dockerfile_dir} #Dockerfile 构建
docker save -o ubuntu_14.04.tar ubuntu:14.04 #保存
docker load --input ubuntu_14.04.tar #导入

#容器
docker ps #查看容器信息
docker rm #删掉容器（-f 删除运行中）
docker inspect #查看指定容器详细信息（可获取ip，pid等信息）
docker logs insane_babbage #查看容器log
docker port CONTAINER [PRIVATE_PORT[/PROTO]] #查看端口映射
docker start|stop|restart insane_babbage #启动终止重启
docker attach insane_babbage #进入后台运行的容器 -d（推荐nsenter）| 输出容器内的信息
docker export 7691a814370e > ubuntu.tar #导出快照
cat ubuntu.tar | sudo docker import - test/ubuntu:v1.0 #导入快照
## docker hub 
docker search #搜索镜像
docker pull #下载
docker login #登录
docker push #推送（需登录）

#部署docker项目
docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-   //将服务器项目部署到docker容器中
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH

docker cp实例
将主机/www/runoob目录拷贝到容器96f7f14e99ab的/www目录下。

docker cp /www/runoob 96f7f14e99ab:/www/
将主机/www/runoob目录拷贝到容器96f7f14e99ab中，目录重命名为www。

docker cp /www/runoob 96f7f14e99ab:/www
将容器96f7f14e99ab的/www目录拷贝到主机的/tmp目录中。

docker cp  96f7f14e99ab:/www /tmp/

Docker不常用命令

#docker 容器（服务）重命名
docker rename 原容器名  新容器名

Docker官方演示用到的命令 

##第一部分 方向
## List Docker CLI commands
docker
docker container --help

## Display Docker version and info
docker --version
docker version
docker info

docker run hello-world  ## Execute Docker image
docker image ls  ## List Docker images

## List Docker containers (running, all, all in quiet mode)
docker container ls
docker container ls --all
docker container ls -aq
注：docker ps命令等价于docker container ls命令。

##第二部分 容器 container
docker build -t friendlyhello .  # Create image using this directory's Dockerfile
docker run -p 4000:80 friendlyhello  # Run "friendlyhello" mapping port 4000 to 80
docker run -d -p 4000:80 friendlyhello         # Same thing, but in detached mode
docker container ls                                # List all running containers
docker container ls -a             # List all containers, even those not running
docker container stop            # Gracefully stop the specified container
docker container kill          # Force shutdown of the specified container
docker container rm         # Remove specified container from this machine
docker container rm $(docker container ls -a -q)         # Remove all containers
docker image ls -a                             # List all images on this machine
docker image rm             # Remove specified image from this machine
docker image rm $(docker image ls -a -q)   # Remove all images from this machine
docker login             # Log in this CLI session using your Docker credentials
docker tag  username/repository:tag  # Tag  for upload to registry
docker push username/repository:tag            # Upload tagged image to registry
docker run username/repository:tag                   # Run image from a registry


##第三部分 服务  service
docker stack ls                                            # List stacks or apps
docker stack deploy -c    # Run the specified Compose file
docker service ls                 # List running services associated with an app
docker service ps                   # List tasks associated with an app
docker inspect                    # Inspect task or container
docker container ls -q                                      # List container IDs
docker stack rm                              # Tear down an application
docker swarm leave --force      # Take down a single node swarm from the manager

注意：

此外，还可以利用 ADD 命令复制本地文件到镜像；用 EXPOSE 命令来向外部开放端口；用 CMD 命令来描述容器启动后运行的程序等。例如

# put my local web site in myApp folder to /var/www
ADD myApp /var/www
# expose httpd port
EXPOSE 80
# the command to run
CMD ["/usr/sbin/apachectl", "-D", "FOREGROUND"]

Laradock 是什么?

Laradock是一个利用Docker实现的WEB环境配置工具,集成了大量WEB开发领域会用到的软件,如Redis,Mysql,MongoDB等.为PHP/Laravel开发和部署提供了极大的便利，前面有讲安装Laradock
