前言
目前对docker支持最好的是Ubuntu系统,docker不支持在windows上运行,必须借助docker-machine。docker提供了toolbox用于在windows和mac平台安装docker。
工具箱包括:
docker machine
Docker Engine
Kitematic
docker命令行运行环境
Oracle VM VirtualBox
安装之前需要检查BIOS中虚拟化的设置是否已打开,参考此页面
1、下载安装文件
https://www.docker.com/toolbox
2、双击安装文件进行安装
3、运行docker run hello-world
运行时出现下面的问题
Post http://127.0.0.1:2375/v1.20/containers/create: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it.. * Are you trying to connect to a TLS-enabled daemon without TLS? * Is your docker daemon up and running?
如下解决:
docker-machine regenerate-certs defaultdocker-machine restart default
显示环境变量:
$ docker-machine env default --shell sh export DOCKER_TLS_VERIFY="1" export DOCKER_HOST="tcp://192.168.99.100:2376" export DOCKER_CERT_PATH="C:/Users/apex/.docker/machine/machines/default" export DOCKER_MACHINE_NAME="default" # Run this command to configure your shell: # eval "$(E:/04_Program Files/docker_toolbox/Docker Toolbox/docker-machine.exe env default)"
设置环境变量:
eval "$(docker-machine env default --shell sh)"
再次运行:
$ docker run hello-worldUnable to find image 'hello-world:latest' locallyPulling repository docker.io/library/hello-worldaf340544ed62: Pulling image (latest) from docker.io/library/hello-worldaf340544ed62: Pulling image (latest) from docker.io/library/hello-world, endpoint: https://registry-1.docker.io/v1/af340544ed62: Pulling dependent layers535020c3e8ad: Pulling metadata535020c3e8ad: Pulling fs layer535020c3e8ad: Download completeaf340544ed62: Pulling metadataaf340544ed62: Pulling fs layeraf340544ed62: Download completeaf340544ed62: Download completeStatus: Downloaded newer image for hello-world:latestHello from Docker.This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker Hub account: https://hub.docker.comFor more examples and ideas, visit: https://docs.docker.com/userguide/
