(1) Docker Dockerfile

From centos:centos6 #使用的镜像名及其标记
Maintainer CXM <[email protected]>#建立此镜像的用户信息

RUN yum-y update; Yum Clean All #运行的命令
RUN yum-y install sudo epel-release;

#Sudo requires a TTY. Fix that.
RUN sed-i ' s/.*requiretty$/#Defaults requiretty/'/etc/sudoers

# Install PGDG repo for getting new Postgres RPMs
RUN RPM-IVHhttp://yum.postgresql.org/9.4/redhat/rhel-7-x86_64/pgdg-centos94-9.4-1.noarch.rpm#安装数据库的centos源

# Install Postgres Version 9.4
RUN Yum Install postgresql94-server postgresql94 postgresql94-contrib postgresql94-plperl postgresql94-devel-y-- Nogpgcheck

Note: Docker has a caching function, and when re-executing, the executed commands are no longer repeated, and if this function is not required, you can modify them yourself.

(2) Docker build

Docker build-t cxm:pg94--rm.

#--rm is the cache after execution,. Refers to the Dockerfile storage path is the current path under the Docker file

(3) Docker-server

Docker run--privileged-d--name pg94_run-p 15432:5432-v/pg94/bash_history:/root/.bash_history--volumes-from=pg94_d ATA--link redis_run:redis-v/pg94/src:/src-v/pg94/local:/usr/local cxm:pg94/sbin/init

Comments:

--privileged # Using this parameter, root in container has true root privileges

-D #后台运行

--name #给运行的容器命名

-p Host Port: Container port #指定容器的端口在宿主机的端口, that is, access the port of the host to access the port of the container

-V Host Path: Container path #与-P almost, but here refers to the file

--volumes-from=pg94_data #挂载容器所有的卷

--link Redis_run:redis #连接到另一个容器 (Name:alias)

cxm:pg94 #镜像名

/sbin/init #执行的终端命令

(4) Docker-client

Docker exec-it Pg94_run/bin/bash
