To create a CentOS Docker mirror with Apache service using Dockerfile _docker

Using Dockerfile to create CentOS Docker mirrors with Apache services

List of files prepared on the host:

Dockerfile

#启动ssh和apache服务的角本
run.sh

The above files are placed in the/root/apache_centos directory

Mkdir-p/root/apache_centos
Cd/root/apache_centos

Base mirroring: Mirroring of open SSH services based on mirrored CentOS

[Root@localhost apache_centos]# Docker images
REPOSITORY     TAG         IMAGE ID      CREATED       VIRTUAL SIZE
sshd        dockerfile     411d5fb16366    hours ago    278 MB
CentOS       latest       0f73ae75014f    5 weeks ago     172.3 MB

I. Preparation of RUN.SH documents

Create a new run.sh in the/root/apache_centos directory

Vim run.sh

The contents are as follows:

#!/bin/bash
/usr/sbin/sshd &
/usr/local/apache2/bin/httpd-d foreground

Second, prepare Dockerfile

Create a new dockerfile in the/root/apache_centos directory

Vim Dockerfile

The contents of the document are as follows:

#新生成的镜像是基于sshd:d ockerfile Mirror from
sshd:dockerfile
maintainer by Steven
#安装wget
RUN yum install-y wget
workdir/usr/local/src
#下载并解压源码包
run wget http://apache.fayea.com/httpd/httpd-2.4.17.tar.gz
run TAR-ZXVF httpd-2.4.17.tar.gz
workdir httpd-2.4.17
#编译安装apache
RUN yum install-y gcc make apr-devel Apr AP R-util apr-util-devel pcre-devel
RUN./configure--prefix=/usr/local/apache2--enable-mods-shared=most-- Enable-so
Run make
run make install
#修改apache配置文件
run sed-i ' s/#ServerName www.example.com:80/ ServerName localhost:80/g '/usr/local/apache2/conf/httpd.conf
#启动apache服务
run/usr/local/apache2/bin/ httpd
#复制服务启动脚本并设置权限
ADD run.sh/usr/local/sbin/run.sh
run chmod 755/usr/local/sbin/run.sh
# Open 80-Port
expose
CMD ["/usr/local/sbin/run.sh"]

Note that replacing the current directory in the Dockerfile file cannot be made with the "CD" command, but instead "Workdir".

Third, generate mirrors

Docker build-t Apache_dockerfile:centos.

To view the generated mirrors:

[Root@localhost apache_centos]# Docker images
REPOSITORY     TAG         IMAGE ID      CREATED       VIRTUAL SIZE
Apache_dockerfile  CentOS       f8f30b4a0ee8    minutes ago   440 MB
Apache       CentOS       F92c55dddd07    hours ago    423.9 MB
sshd dockerfile 411d5fb16366 #    hours ago    278 MB
centos       latest       0f73ae75014f    5 weeks ago     172.3 MB

Iv. build containers based on mirroring and test

1. Generate New containers

 Docker run-d-P 2222:22-p 8000:80 apache_dockerfile:centos/usr/local/sbin/run.sh

Map the container's 22 and 80 ports to 2222 ports and 8000 ports on the host, and run the service script.

2. View newly generated containers:

[Root@localhost apache_centos]# Docker ps-a
CONTAINER ID    IMAGE           COMMAND        CREATED       STATUS           PORTS                    NAMES
ae560e497f39    apache_dockerfile:centos  "/usr/local/sbin/run-  seconds ago        up seconds 0.0.0.0:2222->22/tcp, 0.0.0.0:8000->80/tcp  condescending_bardeen

3, testing

Test Apache

[root@localhost apache_centos]# Curl localhost:8000
 
 

Success!

Testing SSH

[root@localhost apache_centos]# ssh localhost-p 2222
root@localhost ' s password:

Success!
