docker制作jdk+tomcat镜像

docker部署TOMCAT项目

一、内核升级

[root@test01 ~]# uname -r   #内核查看确认

2.6.32-696.16.1.el6.x86_64

[root@test01 ~]#

[root@test01 ~]# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

[root@test01 ~]# rpm -Uvh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm #安装yum源

1:elrepo-release         ########################################### [100%]

[root@test01 ~]# yum --enablerepo=elrepo-kernel install kernel-lt -y

修改grub.conf文件

内核升级完毕后修改内核的启动顺序

vim /etc/grub.conf

default=0

二、docker 安装

安装Yum 源

yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

更新Yum

yum update

安装DOCKER

yum install docker-io

查看docker版本

docker version

启动 重启 停止

service docker  start

service docker  restart

service docker  stop

二、制作Tomcat DOCKER镜像

在tomcat-docker目录下执行命令touch Dockerfile创建一个Dockerfile文件

Vim  Dockerfile内容如下，之后保存

# 设置继承的镜像

FROM centos:6.8

# 创建者信息

MAINTAINER qin

# 设置环境变量，所有操作都是非交互式的

ENV DEBIAN_FRONTEND noninteractive

# 设置tomcat的环境变量

ENV CATALINA_HOME /tomcat

ENV JAVA_HOME /java

# 复制tomcat和jdk文件到镜像中

ADD tomcat /tomcat

ADD java /java

# 复制启动脚本至镜像，并赋予脚本可执行权限

ADD run.sh /run.sh

RUN chmod +x /*.sh

RUN chmod +x /tomcat/bin/*.sh

# 暴露接口8091，这是我的tomcat接口，默认为8080

EXPOSE 8091

# 设置自启动命令

CMD ["/run.sh"]

生成镜像

docker build -t repos_local/centos6.8-jdk151-tomcat8:0.0.1 .
