Dockfile打包带tdengine驱动的tomcat自定义镜像

Posted 2022-05-11 gsls200808

普通的tomcat版本跑带tdengine的驱动是跑不起来的，需要自定义打包tdengine客户端进去才可以。

Dockfile内容如下

FROM centos:7.5.1804
MAINTAINER xxx "[e-mail]"
ENV REFRESHED_AT 2018-11-27
WORKDIR /usr/local
RUN mkdir jdk
ADD jdk-8u202-linux-x64.tar.gz /usr/local/jdk
ADD apache-tomcat-8.5.40.tar.gz /usr/local/
RUN ln -s /usr/local/apache-tomcat-8.5.40 /usr/local/tomcat
ENV JAVA_HOME=/usr/local/jdk/jdk1.8.0_202
ENV JRE_HOME=$JAVA_HOME/jre
ENV CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
ENV PATH=/sbin:$JAVA_HOME/bin:$PATH
RUN chmod +x /usr/local/tomcat/bin/catalina.sh
RUN mkdir tdengineclient
ADD TDengine-client-2.4.0.12-Linux-x64.tar.gz /usr/local/
RUN cd /usr/local/TDengine-client-2.4.0.12/ && ./install_client.sh
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
EXPOSE 8080
ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]

Dockefile同级目录需要有

jdk-8u202-linux-x64.tar.gz

apache-tomcat-8.5.40.tar.gz

TDengine-client-2.4.0.12-Linux-x64.tar.gz

最后执行如下命令完成打包

docker build -t tomcat:8 .

启动tomcat命令如下

docker run -itd \\
--name=my-tomcat \\
-v "/root/my/tomcat/conf:/usr/local/apache-tomcat-8.5.40/conf"  \\
-v "/root/my/tomcat/webapps:/usr/local/apache-tomcat-8.5.40/webapps" \\
-v "/root/my/tomcat/data/logs:/data/logs"  \\
-p '8080:8080'   \\
--privileged=true   \\
--restart=always   \\
tomcat:8

docker-compose yml配置如下

version: '2'
services:
    my-tomcat:
     container_name: my-tomcat
     image: tomcat:8
     volumes:
         - "/root/my/tomcat/conf:/usr/local//apache-tomcat-8.5.40/conf"
         - "/root/my/tomcat/webapps:/usr/local//apache-tomcat-8.5.40/webapps"
         - "/root/my/tomcat/data/logs:/data/logs"
     ports:
         - '8080:8080'
     environment:
         - TZ=Asia/Shanghai
     privileged: true
     restart: always

其中/root/my/tomcat/conf 为tomcat的config目录，/root/my/tomcat/webapps为tomcat的webapp目录
