冷不防 2024-04-20 12:18 95阅读 0赞

#### 1、准备要上传镜像的材料 ####

apache-tomcat-8.5.83.tar.gz  
jdk-8u202-linux-x64.tar.gz

jdk 和Tomcat自己去官网下载

#### 2、编写Dockerfile 文件 ####

# 基础镜像
    FROM ubuntu
     
    # 描述
    MAINTAINER jdk_comcat:8
     
    # 解压与复制jdk.tar.gz
    # 由于add/copy的文件必须使用上下文目录的内容, 因此要先将jdk.tar.gz拷贝到当前目录
    ADD jdk-8u202-linux-x64.tar.gz /usr/local
    ADD apache-tomcat-8.5.83.tar.gz /usr/local
     
    # 配置 JDK 的环境变量和字符集
    ENV JAVA_HOME /usr/local/jdk1.8.0_202
    ENV PATH $JAVA_HOME/bin:$PATH
    ENV CLASSPATH .:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    ENV LANG C.UTF-8
     
    # 配置tomcat环境变量
    ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.83
    ENV CATALINA_BASE /usr/local/apache-tomcat-8.5.83
    ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
     
    # 暴露端口
    EXPOSE 8080
     
    # 启动tomcat -- 最后的命令要一直运行下去，以防容器退出
    ENTRYPOINT /usr/local/apache-tomcat-8.5.83/bin/startup.sh && tail -f /usr/local/apache-tomcat-8.5.83/logs/catalina.out

#### 3、构建镜像 ####

采用docker build 指令构建jdk\_tomcat:8指定的版本：

[root@localhost tomcat]# sudo docker build -t jdk_tomcat:8 .
    Sending build context to Docker daemon  204.7MB
    Step 1/13 : FROM ubuntu
     ---> ba6acccedd29
    Step 2/13 : MAINTAINER jdk_comcat:8
     ---> Running in b5c84e47128f
    Removing intermediate container b5c84e47128f
     ---> 72de2dce1ee2
    Step 3/13 : ADD jdk-8u202-linux-x64.tar.gz /usr/local
     ---> 021c4fdb4c85
    Step 4/13 : ADD apache-tomcat-8.5.83.tar.gz /usr/local
     ---> cdcc494eb5dc

     ---> Running in 7cf34f21e792
    Removing intermediate container 7cf34f21e792
     ---> f22b2517ccf8
    Step 7/13 : ENV CLASSPATH .:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
     ---> Running in ecff0f632b98
    Removing intermediate container ecff0f632b98
     ---> 27cf9956e0b1
    Step 8/13 : ENV LANG C.UTF-8
     ---> Running in 5d06830ff12a
    Removing intermediate container 5d06830ff12a
     ---> e512ebf2fa3b
    Step 9/13 : ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.83
     ---> Running in fe6a94685e33
    Removing intermediate container fe6a94685e33
     ---> 2d7ac9eba680
    Step 10/13 : ENV CATALINA_BASE /usr/local/apache-tomcat-8.5.83

     ---> e7333a163afb
    Step 11/13 : ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
     ---> Running in 84debe4a844f
    Removing intermediate container 84debe4a844f
     ---> f72e6f752d2c
    Step 12/13 : EXPOSE 8080
     ---> Running in 2e9d09b5830c
    Removing intermediate container 2e9d09b5830c
     ---> c9d2b65d292f
    Step 13/13 : ENTRYPOINT /usr/local/apache-tomcat-8.5.83/bin/startup.sh && tail -f /usr/local/apache-tomcat-8.5.83/logs/catalina.out
     ---> Running in ad6353686b35
    Removing intermediate container ad6353686b35
     ---> fa0bafc06889
    Successfully built fa0bafc06889
    Successfully tagged jdk_tomcat:8

#### 4、启动当前镜像 ####

通过docker run 启动jdk\_tomcat:8 当前镜像

sudo docker run -itd -p 8080:8080  --name jdk_tomcat jdk_tomcat:8

启动成功后，通过 docker images 查看镜像。  
通过docker ps查看容器：

[root@localhost tomcat]# docker ps
    CONTAINER ID   IMAGE              COMMAND                  CREATED         STATUS                    PORTS                                                                                                                               NAMES
    1faae7d0ce90   jdk_tomcat:8       "/bin/sh -c '/usr/lo…"   4 seconds ago   Up 3 seconds              0.0.0.0:8080->8080/tcp, :::8080->8080/tcp                                                                                           jdk_tomcat

#### 5、准备阿里云账号 ####

##### 5.1、创建镜像仓库： #####

![在这里插入图片描述][f3eeabbeb6b94abb9a7044bd93c30b12.png]

##### 5.2、选择本地仓库创建镜像库 #####

![在这里插入图片描述][9a0c17722232433aa9c6e2299615dd8d.png]

##### 5.3、在客户端登陆阿里云 #####

通过docker login 登陆

docker login --username=*** registry.cn-hangzhou.aliyuncs.com

输入自己的密码：

问题：Error response from daemon: Get “https://registry.cn-hangzhou.aliyuncs.com/v2/”: unauthorized: authentication required  
解决方法：  
1、不要使用第三方授权登陆，自己注册一个阿里云账号  
2、修改DNS存值。

[root@localhost tomcat]# vi /etc/resolv.conf 
    # Generated by NetworkManager
    search localdomain
    nameserver 192.168.220.2

保证DNS 存在值

##### 5.4 添加标签和推送 #####

通过docker images 获取镜像ID，然后通过阿里给的指令推送：

$ docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:[镜像版本号]
    $ docker push registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:[镜像版本号]

[root@localhost tomcat]# docker tag fa0bafc06889  registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:8
    [root@localhost tomcat]# docker push  registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:8
    The push refers to repository [registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat]
    032714f94ad3: Pushed 
    4e3b53d854a6: Pushed 
    9f54eef41275: Pushed 
    8: digest: sha256:68b03cdf1d81b57489b7bf6de2761d7c0cce826e85c31a93fe11a029b3a21eb5 size: 954

##### 5.5 查看和拉取 #####

查看阿里云镜像仓库：  
![在这里插入图片描述][3d32681f14de46619f1b718fd458a26f.png]

拉取上传的镜像：

sudo docker pull registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_comcat:8

#### 6、制作JDK 镜像 ####

同理制作JDK镜像，添加jar包，测试jdk镜像是否成功：

docker run -d --name eureka-9001  --privileged=true   --network host --restart always -w /usr/eureka/  -v /data/eureka:/usr/eureka  registry.cn-hangzhou.aliyuncs.com/lskdxhl/jdk_li:8 /bin/sh -c 'sh start.sh'

成功启动Eureka:
