ubuntu安装docker{ubuntu16.04下安装docker}

   一、开始安装

第一步:   由于apt官方库里的docker版本可能比较旧,所以先卸载可能存在的旧版本:

$ sudo apt-get remove docker docker-engine docker-ce docker.io

第二步、更新apt包索引:

$ sudo apt-get update

第三步、  安装以下包以使apt可以通过HTTPS使用存储库(repository):

$ sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common

第四步、 添加Docker官方的GPG密钥:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

第五步: 使用下面的命令来设置stable存储库:

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

第六步:     再更新一下apt包索引:

$ sudo apt-get update

第七步:    安装最新版本的Docker CE:

$ sudo apt-get install -y docker-ce

在生产系统上,可能会需要应该安装一个特定版本的Docker CE,而不是总是使用最新版本:

第八步:列出可用的版本:
            $ apt-cache madison docker-ce
选择要安装的特定版本,第二列是版本字符串,第三列是存储库名称,它指示包来自哪个存储库,以及扩展它的稳定性级别。要安装一个特定的版本,将版本字符串附加到包名中,并通过等号(=)分隔它们:

$ sudo apt-get install docker-ce=<VERSION> 

验证docker

    查看docker服务是否启动:

$ systemctl status docker

    1

    若未启动,则启动docker服务:

$ sudo systemctl start docker

    1

    经典的hello world:

$ sudo docker run hello-world

二、运行报错:解决方案

昨天在使用docker 时,将 image 文件从仓库抓取到本地一直报错,经过尝试,终于得以解决。

错误信息如下:

[root@archlinux ~]# docker image pull library/hello-world
Using default tag: latest
Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: dial tcp 52.20.146.203:443: i/o timeout

或者:

[root@archlinux quanxj]# docker image pull library/hello-world
Using default tag: latest
latest: Pulling from library/hello-world
ca4f61b1923c: Pull complete
error pulling image configuration: Get https://registry-1.docker.io/v2/library/hello-world/blobs/sha256:f2a91732366c0332ccd7afd2a5c4ff2b9af81f549370f7a19acd460f87686bc7: dial tcp 35.169.231.249:443: i/o timeout

解决方法如下:
第一步:通过dig @114.114.114.114 registry-1.docker.io找到可用IP

[root@archlinux ~]# dig @114.114.114.114 registry-1.docker.io
; <<>> DiG 9.12.0 <<>> @114.114.114.114 registry-1.docker.io

;; MSG SIZE rcvd: 189

第二步:尝试修改/etc/hosts强制docker.io相关的域名解析到其它可用IP

vim /etc/hosts
  • 1

添加一个可用IP:

52.5.185.86 registry-1.docker.io
  • 1

保存之后重试:

[root@archlinux quanxj]# docker image pull library/hello-world
Using default tag: latest
latest: Pulling from library/hello-world
ca4f61b1923c: Already exists
Digest: sha256:083de497cff944f969d8499ab94f07134c50bcf5e6b9559b27182d3fa80ce3f7
Status: Downloaded newer image for hello-world:latest

验证:

[root@archlinux quanxj]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest f2a91732366c 3 months ago 1.85kB 三、如果还不行,则用如下方法: [root@teddy /]# docker search ubuntu
Error response from daemon: Get https://index.docker.io/v1/search?q=ubuntu: read tcp 52.200.132.201:443: i/o timeout docker在中国已经有了仓库:https://www.docker-cn.com/registry-mirror 根据上面网站提供的修改方法。 进入/etc/docker 查看有没有 daemon.json。这是docker默认的配置文件。 如果没有新建touch daemon.json,如果有,则修改。 [root@teddy docker]# vi daemon.json
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
} 保存退出。 重启docker服务 service docker restart 成功! [root@teddy docker]# docker search ubuntu
