# 注意：
# 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，您可以通过以下方式开启。同理可以开启各种测试版本等。
# vim /etc/yum.repos.d/docker-ee.repo
#   将[docker-ce-test]下方的enabled=0修改为enabled=1
#
# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
#   Loading mirror speeds from cached hostfile
#   Loaded plugins: branch, fastestmirror, langpacks

1、若您安装过**docker**，需要先删掉，之后再安装依赖:

sudo yum remove docker docker-common docker-selinux docker-engine
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

2、根据版本不同，下载repo文件。您使用的发行版： 

wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.huaweicloud.com/docker-ce/linux/centos/docker-ce.repo

软件仓库地址替换为：

sudo sed -i 's+download.docker.com+mirrors.huaweicloud.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

3、更新索引文件并安装

sudo yum makecache 

 dnf install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm

sudo yum install docker-ce

docker tag 详解

docker tag 用于给镜像打标签，语法如下：

docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

① 比如我现在有一个 centos 镜像：

[root@localhost ~]$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
centos              latest              1e1148e4cc2c        2 weeks ago         202MB

② 我对 centos 进行开发，开发了第一个版本，我就可以对这个版本打标签，打完标签后会生成新的镜像：

[root@localhost ~]$ docker tag centos centos:v1
[root@localhost ~]$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
centos              latest              1e1148e4cc2c        2 weeks ago         202MB
centos              v1                  1e1148e4cc2c        2 weeks ago         202MB

③ 我继续对 centos 进行开发，开发了第二个版本，继续打标签：

[root@localhost ~]$ docker tag centos centos:v2
[root@localhost ~]$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
centos              latest              1e1148e4cc2c        2 weeks ago         202MB
centos              v1                  1e1148e4cc2c        2 weeks ago         202MB
centos              v2                  1e1148e4cc2c        2 weeks ago         202MB

④ 以此类推，每开发一个版本打一个标签，如果以后我想回滚版本，就可以使用指定标签的镜像来创建容器：

[root@localhost ~]$ docker run -itd centos:v1

Docker容器内不能联网的6种解决方案

更新时间：2018年10月15日 14:18:02 作者：数据架构师我要评论

今天小编就为大家分享一篇关于Docker容器内不能联网的6种解决方案，小编觉得内容挺不错的，现在分享给大家，具有很好的参考价值，需要的朋友一起跟随小编来看看吧

Docker容器内不能联网的6种解决方案

注：下面的方法是在容器内能ping通公网IP的解决方案，如果连公网IP都ping不通，那主机可能也上不了网（尝试ping 8.8.8.8）

1.使用–net:host选项

sudo docker run --net:host --name ubuntu_bash -i -t ubuntu:latest /bin/bash

2.使用–dns选项

sudo docker run --dns 8.8.8.8 --dns 8.8.4.4 --name ubuntu_bash -i -t ubuntu:latest /bin/bash

3.改dns server

vi /etc/default/docker 去掉“docker_OPTS="–dns 8.8.8.8 --dns 8.8.4.4"”前的#号

4.不用dnsmasq

vi /etc/NetworkManager/NetworkManager.conf 在dns=dnsmasq前加个#号注释掉

sudo restart network-manager``sudo restart docker

5.重建docker0网络

pkill docker       #终止进程``
iptables -t nat -F     #清空nat表的所有链``
ifconfig docker0 down  #停止docker默认网桥``
brctl delbr docker0    #删除网桥``
docker -d

6.直接在docker内修改/etc/hosts

总结

以上就是这篇文章的全部内容了，希望本文的内容对大家的学习或者工作具有一定的参考学习价值，谢谢大家对脚本之家的支持。如果你想了解更多相关内容请查看下面相关链接

docker安装centos7镜像

拉取centos7镜像

[root@localhost ~]# docker pull centos:7

拉取centos7镜像

启动镜像centos7，如果不指定 /bin/bash，容器运行后会自动停止

[root@localhost ~]# docker run -d -i -t <IMAGE ID> /bin/bash

进入容器

[root@localhost ~]# docker exec -it <CONTAINER ID> bash

进入后发现没有ifconfig，直接yum安装

[root@8f10fbd6bd5a /]# yum install -y net-tools

无法ping外网，查找资料重建docker0网络解决，资料地址


[root@localhost ~]# pkill docker   
[root@localhost ~]# iptables -t nat -F
[root@localhost ~]# ifconfig docker0 down
[root@localhost ~]# brctl delbr docker0

1.下载镜像（management版本的才带有web管理界面）

docker pull rabbitmq:3.7.18-management

2.创建容器（监听端口：5672，web管理界面端口：15672）

docker run --name myrabbitmq -d -p 5672:5672 -p 15672:15672 rabbitmq:3.7.18-management

3.使用默认用户名、密码：guest/guest 登陆

http://192.168.40.100:15672

http://192.168.40.100:15672

#1.安装rabbitmq，使用镜像加速
#下载的是有管理界面的镜像
[root@localhost ~]# docker pull rabbitmq:3.7.18-management
[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
rabbitmq            3.7.18-management   2a0e4a1d8b3e        8 months ago        179MB
#2.运行rabbitmq
##### 端口：5672 客户端和rabbitmq通信 15672：管理界面的web页面

docker run -d -p 5672:5672 -p 15672:15672 --name myrabbitmq rabbitmq:3.7.18-management

#3.查看运行
docker ps
#设置docker中myrabbitmq自动启动
[root@localhost ~]# docker update myrabbitmq --restart=always
myrabbitmq

http://192.168.40.100:15672/

安装Zookeeper

[root@localhost ~]# docker pull zookeeper
[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
zookeeper           latest              411f5595aa97        13 days ago         252MB
[root@localhost ~]# docker run -d --name zk02 -p 2181:2181  zookeeper  --restart always

zookeeper client port 2181
follower port 2888
election port 3888
docker run -d --name zk02 -p 2181:2181 -p 2888:2888 -p 3888:3888 --restart always zookeeper  
[root@localhost ~]# docker exec -it zk02 bash

3、Dubbo、Zookeeper整合

Docker：docker国内镜像加速

启动java项目时出现 com.sun.xml.internal.bind.v2.ContextFactory 异常

docker中配置主从复制

 mkdir -p /mydata/mysql2/log
 mkdir -p /mydata/mysql2/data
 mkdir -p /mydata/mysql2/conf
docker run -p 3309:3306 --name mysql2 -v /mydata/mysql2/log:/var/log/ -v/mydata/mysql2/data:/var/lib/mysql -v /mydata/mysql2/conf:/etc/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7
