## **docker安装** ##

**安装前提**

CentOS 7以上版本

[https://docs.docker.com/engine/installation/linux/docker-ce/centos/\#install-from-a-package][https_docs.docker.com_engine_installation_linux_docker-ce_centos_install-from-a-package]

[https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-centos-7][https_www.digitalocean.com_community_tutorials_how-to-install-and-use-docker-on-centos-7]

**安装步骤**

<table style="margin-left:5.4pt;"> 
 <tbody> 
  <tr> 
   <td style="background-color:#d8d8d8;"> <p style="margin-left:0pt;">sudo yum install -y yum-utils device-mapper-persistent-data lvm2</p> <p style="margin-left:0pt;">sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo</p> <p style="margin-left:0pt;">sudo yum makecache fast</p> <p style="margin-left:0pt;">sudo yum install docker-ce</p> </td> 
  </tr> 
 </tbody> 
</table>

注意：安装带版本号的稳定版的docker-ce，不要安装不稳定的最新版本。

启动docker服务：

service docker start

systemctl

添加docker的用户组，避免每次执行docker需要sudo

sudo usermod -aG docker $(whoami)

## **docker常用命令** ##

查看镜像

docker images

查看容器

docker ps –a

启动

docker run –d –p 5000:5000 –v /usr/apps/software/docker/registry:/tmp/registry registry

\-d 后台启动

\-p 端口映射

\-v  Bind mount a volume (e.g., from the host: -v /host:/container, from Docker: -v /container)

\--rm Automatically remove the container when it exits (incompatible with -d)，default false

删除镜像

docker rmi \[image-id\]

删除容器

docker rm \[container-id\]

停止容器

docker stop \[container-id\]

进入容器

docker attach \[image-name\]

docker exec –ti \[container-id\] /bin/bash

查看容器日志

docker logs \[container\_id\]

提交容器d

docker commit \[container\_id\] \[image-name\]

存出镜像

docker save –o centos7\_pg93\_1.1.tar centos7\_pg93:1.1

docker run --name yourappname -e POSTGRES\_PASSWORD=mysecretpassword  -e POSTGRES\_USER=xxx -d -p xxxx:5432 postgres

查看docker容器的IP地址

docker inspect --format='\{ \{.NetworkSettings.IPAddress\}\}' $CONTAINER\_ID

docker build \--no-cache=true -t friendlyname .  \# Create image using this directory's Dockerfile

docker run -p 4000:80 friendlyname  \# Run "friendlyname" mapping port 4000 to 80

docker run -d -p 4000:80 friendlyname         \# 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 <hash>           \# Gracefully stop the specified container

docker container kill <hash>         \# Force shutdown of the specified container

docker container rm <hash>        \# 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 <image id>            \# 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 <image> username/repository:tag  \# Tag <image> for upload to registry

docker push username/repository:tag            \# Upload tagged image to registry

docker run username/repository:tag                   \# Run image from a registry

## **镜像市场** ##

官方市场

Docker store

Daocloud

[http://hub.daocloud.io/][http_hub.daocloud.io]

# **docker centos7基础镜像** #

## **下载镜像** ##

从docker hub下载centos

docker pull centos

注意：安装带版本号的稳定版的centos，不要安装不稳定的centos最新版本。

Docker hub

[https://hub.docker.com/explore/][https_hub.docker.com_explore]

docker store

[https://store.docker.com/][https_store.docker.com]

## **设置时区** ##

先查看时区

date -R

修改时区：

（将Asia/shanghai-上海时区写入当前时区）\#cp -f /usr/share/zoneinfo/Asia/Shanghai     /etc/localtime

提示是否覆盖,输入Y回车,

然后\#date

查看时区和时间（CST,中国时区）

## **添加中文编码方式** ##

中文环境设置：

localedef -i zh\_CN -f GB2312 zh\_CN

localedef -i zh\_CN -f GB2312 zh\_CN.GB2312

localedef -i zh\_CN -f GBK zh\_CN.GBK

localedef -i zh\_CN -f UTF-8 zh\_CN.UTF-8

locale -a

localectl list-locales | grep zh

## **docker的centos7镜像systemctl问题** ##

解决docker 官方镜像centos7的systemctl不起作用的方法

docker run --privileged  -p 15432:5432 -p 10022:22 -d centos7\_pg93:0.1 /usr/sbin/init

## **添加运维管理所需包** ##

sar

htop

net-tools：ping、ifconfig、telnet、netstat
