docker-dockerfile构建与部署tomcat

dockerfile构建与部署tomcat

1. 创建dockerfile存放目录

1.1 创建目录

[root@docker ~]# mkdir -p /dockerfile
[root@docker ~]# cd /dockerfile/
[root@docker dockerfile]# mkdir -p tomcat
[root@docker dockerfile]# cd tomcat/

2. 创建tomcat dockerfile配置文件

2.1 创建文件

[root@docker nginx]# touch Dockerfile

2.2 下载地址

软件准备
JDK下载：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 
Tomcat下载：http://tomcat.apache.org/
以上是软件在的连接，可以参考

2.3 下载tomcat包

[root@docker tomcat]# wget https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.59/bin/apache-tomcat-8.5.59.tar.gz

3 编写文件dockerfile文件

[root@docker tomcat]# vim Dockerfile 
[root@docker tomcat]# cat Dockerfile 
# this docker file
# VERSION 1.0
# author: shichao
# email: shichao@scajy.cn

FROM centos:7
MAINTAINER  shichao@scajy.cn
ENV VERSION=8.5.59

RUN yum install -y gcc gcc-c++ make gd-devel libxml2-devel libcurl-devel libjpeg-devel libpng-devel openssl-devel net-tools wget curl unzip iproute java-1.8.0-openjdk && yum clean all  && rm -rf /var/cache/yum/* 
ADD apache-tomcat-{{VERSION}}.tar.gz /usr/local
RUN mv /usr/local/apache-tomcat-{{VERSION}}   /usr/local/tomcat &&
	sed -i '1a JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom"' /usr/local/tomcat/bin/catalina.sh && 
	ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

ENV PATH /usr/local/tomcat/bin:$PATH

WORKDIR /usr/local/tomcat
EXPOSE 9000
CMD ["catalina.sh", "run"]

4. 构建tomcat

[root@docker tomcat]# docker build -t tomcat:v1 .

5. 查看镜像，验证是否构建成功

[root@docker php]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

centos              latest              0d120b6ccaa8        2 months ago        215MB

6. 使用tomcat镜像，创建docker容器

[root@docker php]# docker run -d --name=tomcat --network=test -p8080:8080 tomcat:v1
84a078c1881295674cfb4c1c5258975481f2548885cb4c42d433b019f2d775ed

7. 验证tomcat容器是否正常运行

[root@docker php]# docker ps -a 
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS                              NAMES
84a078c18812        tomcat:v1           "catalina.sh run"   About a minute ago   Up About a minute   0.0.0.0:8080->8080/tcp, 9000/tcp   tomcat

8. 浏览器访问验证

• 查看本机ip

  [root@docker php]# ifconfig eth0
  eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
          inet 192.168.200.126  netmask 255.255.255.0  broadcast 192.168.200.255
