Docker in depth 1-try running a simple web environment

Purpose: Add a Web environment on the base image (PCNK/BASE:V2): Sync

Practice: Start a new container, and then incrementally add the Web service, and then submit to the image, where port mappings are used, and data volumes are mounted.

First, the "Pcnk/base:v2" on the base image run a container "Web" to install sync httpd and other services required 1) container "Web" [[email protected]  base]$ docker run -d -v /home/download:/home/download -v /home/datacenter:/ data --name web -p 10032:22 pcnk/base:v2    152d0ca20346fc4a0d0a5a8fe04671910dcc685801f572159ae3c7f5dd2ecf43[[email protected] base]$  docker ps -lcontainer id        image                COMMAND                 CREATED              STATUS               PORTS                    names152d0ca20346        pcnk/base:v2         "/usr/bin/supervisor   7 seconds ago       up  6 seconds        0.0.0.0:10032->22/tcp    web   [[email protected] base]$ ssh -p 10032 [email  Protected][email protected] ' s password: last login: wed may  6  10:11:26 2015 from 172.17.42.12) Adjust the time: [[email protected] /]# mv -f /etc /localtime /etc/localtime.old[[email protected] /]# ln -s /usr/share/zoneinfo/ asia/shanghai /etc/localtime[[email protected] /]# echo  ' ZONE= "Asia/Shanghai"   >/etc/sysconfig/clock[[email protected] /]# cd /home/download/vriteam-sync-0.2.4[[email  protected] vriteam-sync-0.2.4]# yum -y install wget gcc perl autoconf automake  make bzip2 tar zip && yum clean all[[email protected]  VRITEAM-SYNC-0.2.4]#&NBSP;./INSTALL&NBSP;ALL3) Install the PHP module: [[email protected] vriteam-sync-0.2.4]# . /install ssh2[[email protected] vriteam-sync-0.2.4]# ./install svn[[email  Protected] vriteam-sync-0.2.4]# cd /etc/php.d[[email protected] php.d]# cat  ssh2.ini svn.ini ; Enable ssh2 extension moduleextension=ssh2.so;  enable svn extension moduleextension=svn.so[[email protected] vriteam-sync-0.2.4]#  ls /lib64/php/modules/curl.so  fileinfo.so  json.so  mysqli.so   mysql.so  pdo_mysql.so  pdo.so  pdo_sqlite.so  phar.so   sqlite3.so  ssh2.so  svn.so  zip.so[[email protected] conf.d]# yum clean  ALL4) Adjust the configuration of the httpd: [[Email protected] supervisor.d]# ln -s /data/supervisor.d/httpd.ini  .
