Docker安装记录

摘要：安装docker中遇到的问题，方便大家今后安装的时候好处理　　

１．下载　docker的ded包２．安装　sudo dpkg -i .ded ３．运行　sudo docker run hello-world　测试

报一下错误

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
9bb5a5d4561a: Pulling fs layer 
docker: error pulling image configuration: Get https://dseasb33srnrn.cloudfront.net/registry-v2/docker/registry/v2/blobs/sha256/e3/e38bc07ac18ee64e6d59cf2eafcdddf9cec2364dfe129fe0af75f1b0194e0c96/data?Expires=1524943858&Signature=JDmRGceAlM6iJb8aIC5cu7mrrsgSysG~Y~IctwjGcAsfM64nEYh6JkmmYxsKItVlIqNbanKXxajcA8QhQqyoLZ8xQxMFOq~5PsfgQlfj8jaSvznGx3~gf0ShjThON4Kh6LorTOP0MkTLvXBTW99yooLM9XZ2583II5dnbw4SCmA_&Key-Pair-Id=APKAJECH5M7VWIS5YZ6Q: net/http: TLS handshake timeout.
See 'docker run --help'.

４．网上的一大堆都不怎么好使，执行下面两行命令

echo "DOCKER_OPTS=\"\$DOCKER_OPTS --registry-mirror=http://f2d6cb40.m.daocloud.io\"" | sudo tee -a /etc/default/docker
sudo service docker restart
再次运行测试命令  ５．成功后如下，显示

Hello 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.
    (amd64)
 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 bash

docker使用

第一次使用:runoob@runoob:~$ docker run ubuntu:15.10 /bin/echo "Hello world"
它会自动找ubuntu:15.10镜像，没有会自动下载，下载完成后如下图 ![img](/images/assets/docek.png)

进入容器对话功能　　

  docker run -i -t ubuntu:15.10 /bin/bash
  通过运行exit命令或者使用CTRL+D来退出容器

后台运行　　

  docker run -d ubuntu:15.10 /bin/sh -c "while true; do echo hello world; sleep 1; done"

查看正在运行的容器　　

  docker ps
    
  CONTAINER ID:容器ID
  NAMES:自动分配的容器名称
  在容器内使用docker logs命令，查看容器内的标准输出

查看容器的输出

  docker logs CONTAINER ID
  docker logs　NAMES

停止容器　　

  docker stop CONTAINER ID
  docker stop　NAMES
