Docker怎么构建JAVA环境镜像

这篇文章主要讲解了"Docker怎么构建JAVA环境镜像"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"Docker怎么构建JAVA环境镜像"吧！

1\ 需要提前下载软件包jdk和tomcat

[root@docker-master ~]# vim Dockerfile-JavaFROM centos:6MAINTAINER gujiworkADD jdk-8u151-linux-x64.tar.gz /usr/localENV JAVA_HOME /usr/local/jdk1.8.0_151ADD apache-tomcat-7.0.82.tar.gz /usr/localWORKDIR /usr/local/apache-tomcat-7.0.82ENTRYPOINT ["bin/catalina.sh","run"]#暴露8080端口EXPOSE 8080

2\执行build之后便开始构建成镜像

[root@docker-master ~]# docker build -t tomcat:v1 -f ./Dockerfile-Java  .Sending build context to Docker daemon  3.045GBStep 1/8 : FROM centos:66: Pulling from library/centos9bfcefca2b8d: Pull completeDigest: sha256:573923afbed3faf8000ad6eb333ebeb1d46e753d3ae23a6f59b528c7e1531747Status: Downloaded newer image for centos:6 ---> 0cbf37812bffStep 2/8 : MAINTAINER gujiwork ---> Running in 2205a6b1c70d ---> 807741f8ef42Removing intermediate container 2205a6b1c70dStep 3/8 : ADD jdk-8u151-linux-x64.tar.gz /usr/local ---> 617e8b4fa97dStep 4/8 : ENV JAVA_HOME /usr/local/jdk1.8.0_151 ---> Running in deded76bd1f4 ---> bfe5b16b5dfbRemoving intermediate container deded76bd1f4Step 5/8 : ADD apache-tomcat-7.0.82.tar.gz /usr/local ---> ad01015a58f5Step 6/8 : WORKDIR /usr/local/tomcat ---> 70c90ddeb127Removing intermediate container 385c8cafef5bStep 7/8 : ENTRYPOINT bin/catalina.sh run ---> Running in fb186dfb8068 ---> 0c9299e34658Removing intermediate container fb186dfb8068Step 8/8 : EXPOSE 8080 ---> Running in 44161cdc051b ---> b0ca287e65baRemoving intermediate container 44161cdc051bSuccessfully built b0ca287e65baSuccessfully tagged tomcat:v1

3\可通过docker images查看构建的镜像

[root@docker-master ~]# docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEtomcat              v1                  b0ca287e65ba        2 minutes ago       592MBnginx               latest              568c4670fa80        2 weeks ago         109MBcentos              6                   0cbf37812bff        2 months ago        194MBcentos              latest              3fa822599e10        12 months ago       204MB

4\ 启动docker tomcat容器,使用宿主机IP访问页面进行测试.

[root@docker-master ~]# docker run -itd --name web01 -p 80:8080 tomcat:v12c4d214c8ce9aef03409d7e02a43ed10247480de22c3b9d9c31b4e8d73eca45f[root@docker-master ~]# docker psCONTAINER ID        IMAGE               COMMAND                 CREATED             STATUS              PORTS                  NAMES2c4d214c8ce9        tomcat:v1           "bin/catalina.sh run"   29 seconds ago      Up 27 seconds       0.0.0.0:80->8080/tcp   web01# 查看本机网卡IP地址[root@docker-master ~]# ifconfig  ens33ens33: flags=4163  mtu 1500        inet 172.18.18.10  netmask 255.255.255.0  broadcast 172.18.18.255        inet6 fe80::20c:29ff:fe80:de01  prefixlen 64  scopeid 0x20        ether 00:0c:29:80:de:01  txqueuelen 1000  (Ethernet)        RX packets 55747  bytes 72954144 (69.5 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 30192  bytes 2373785 (2.2 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

5\配置开启SSH远程登录,方便测试及开发进行相关的排错查看

[root@docker-master ~]# vim Dockerfile-Java-sshFROM centos:6MAINTAINER gujiworkENV JAVA_HOME /usr/local/jdk1.8.0_151ENV ROOT_PASSWORD 123456ADD jdk-8u151-linux-x64.tar.gz /usr/localADD apache-tomcat-7.0.82.tar.gz /usr/localCOPY ./start.sh /usr/local/start.shRUN yum install -y openssh-server && \    echo $ROOT_PASSWORD |passwd --stdin root && \    ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key && \    ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key && \    echo 'UseDNS no' >> /etc/ssh/sshd_config && \    sed -i -e '/pam_loginuid.so/d' /etc/pam.d/sshd && \    chmod +x /usr/local/start.sh && \    rm -rf /usr/local/apache-tomcat-7.0.82.tar.gzWORKDIR /usr/local/apache-tomcat-7.0.82ENTRYPOINT ["/usr/local/start.sh","run"]#暴露8080和22端口EXPOSE 8080EXPOSE 22

6\start.sh脚本,用于启动容器内的多个服务

[root@docker-master ~]# vim start.sh#!/bin/bashTomcatDir="/usr/local/apache-tomcat-7.0.82"cd $TomcatDir ; ./bin/startup.sh/usr/sbin/sshd -Dtail -f /var/log/*

7\重新构建镜像,tag标记为tomcat:v2

[root@docker-master ~]# docker build -t tomcat:v2 -f Dockerfile-Java-ssh .Sending build context to Docker daemon  3.045GBStep 1/15 : FROM centos:6 ---> 0cbf37812bffStep 2/15 : MAINTAINER gujiwork --->

8\启动容器 -p 表示映射到宿主机的固定端口, -P为随机端口

[root@docker-master ~]# docker run -itd --name web02 -p 80:8080 -p 2222:22 tomcat:v29cc734888d1f87bbbad4536c05dc1a62bae4f12ae8d88560067d1d89039f2ca1

9\ 测试远程连接是否可以登陆

10\此时便可以通过宿主机映射的2222端口进行连接了.
