Basic environment description

# cat / etc/redhat-releaseCentOS release 6.8 (Final)

Set docker image source #

# yum install-y yum-priorities & & rpm- ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm & & rpm--import / etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

Install docker-io and febootstrap to make centos image and generate centos image #

# yum install docker-io-y # install docker# service docker start # launch docker# yum install febootstrap # create Image tool

Make CentOS image file centos6-image directory #

# febootstrap-I bash-I wget-I yum-I iputils-I iproute-I man-I vim-I openssh-server-I openssh-clients-I tar-I gzip centos6 centos6-image http://mirrors.aliyun.com/centos/6/os/x86_64/

-I: installed software package

Centos6: system version

Centos6-image: generated directory name

You can also make a mirror image of CentOS7 and change the address to the address of CentOS7, for example

# febootstrap-I bash-I net-tools-I wget-I yum-I iputils-I iproute-I man-I vim-I openssh-server-I openssh-clients-I tar-I gzip centos7 centos7-image https://mirrors.aliyun.com/centos/7/os/x86_64/

When setting ssh to enter the image, go directly to the root directory (if you do not do this step, you will directly enter the / directory)

# cd centos6-image & & cp etc/skel/.bash* root/

Generate basic image base#

# cd centos6-image & & tar-c. | | docker import-centos6-base |

View Mirror

# docker images

Create docker image of http based on basic image #

# cat DockerfileFROM centos6-base # means to create a MAINTAINER bamboo based on this image # represents the information of the image maker RUN yum install-y yum-priorities & & rpm- ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/Packages/e/epel-release-6-8.noarch.rpm & & rpm--import / etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6RUN yum install tar gzip vim wget httpd httpd-* -yRUN sed-I 's/#ServerName www.example.com:80/ServerName www.example.com:80/' / etc/httpd/conf/httpd.confEXPOSE 80 # indicates the open port number CMD ["/ usr/sbin/httpd" "- D", "FOREGROUND"] # indicates that a Dockerfile can only write one CMD command when the mirror is started. Multiple CMD executes the last # ENTRYPOINT ["/ usr/sbin/httpd", "- D", "FOREGROUND"] # in the same way as CMD

Build Image #

# cd centos6-image & & docker build-t centos6-httpd / root/bamboo-t is followed by the name of the image to be generated, that is, the above centos6-httpd followed by the directory of Dockerfile, which is the directory

View and test #
