Editor to share with you how to customize the tomcat image of Dockerfile in docker, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. Create a directory

[root@t-docker chenzx] # mkdir tomcat9

2. Touch c.txt in the above directory in order to demonstrate the function of the copy instruction

[root@t-docker tomcat9] # touch c.txt

3. Copy the compressed package installed by jdk and tomcat into the previous directory

[root@t-docker tomcat9] # lsatlassian-confluence-6.11.0.tar.gz c.txt jdk1.8.0_65.tar.gz

4. Create a new Dockerfile file

[root@t-docker tomcat9] # cat Dockerfile FROM centosMAINTAINER chenzx# copies the c.txt of the current context of the host to the container / opt path COPY c.txt / opt/container.txt# uses the ADD instruction to add java and tomcat packages to the container, and automatically decompresses ADD atlassian-confluence-6.11.0.tar.gz / optADD jdk1.8.0_65.tar.gz / opt# installs the vim editor RUN yum-y install vim# to set the WORKDIR path for work access Login destination ENV MYPATH / optWORKDIR $MYPATH# configure java and tomcat environment variable ENV JAVA_HOME/ opt/jdk1.8.0_65ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarENV CATALINA_HOME/ opt/atlassian-confluence-6.11.0ENV CATALINA_BASE / opt/atlassian-confluence-6.11.0ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin# container runtime listening port EXPOSE 808 starts Run tomcat#ENTRYPOINT ["/ opt/atlassian-confluence-6.11.0/bin/startup.sh"] # CMD ["/ opt/atlassian-confluence-6.11.0/bin/catalina.sh" when "run"] CMD / opt/atlassian-confluence-6.11.0/bin/startup.sh & & tail-F / opt/atlassian-confluence-6.11.0/logs/catalina.out

6 、 run

[root@t-docker tomcat9] # docker run-d-p 9080 volume/test:/opt/atlassian-confluence-6.11.0/test 8090-- name myt9\-v / volume/test:/opt/atlassian-confluence-6.11.0/test\-v / volume/tomcatlogs:/opt/atlassian-confluence-6.11.0/logs\-- privileged=true\ tomcat9

-v means data volume, volume

[root@t-docker tomcat9] # docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESa4174d4abeba tomcat9 "/ bin/sh-c'/ opt/at …" 7 seconds ago Up 6 seconds 8080/tcp, 0.0.0.0 8090/tcp myt9 9080->

7. Verification

[root@t-docker tomcat9] # docker exec a4174d4abeba ls-ltotal 0drwxr-xr-x 1 1000 1000 42 Sep 2 03:41 atlassian-confluence-6.11.0-rw-r--r-- 1 root root 0 Sep 2 02:38 container.txtdrwxr-xr-x 9 root root 268 Feb 24 2016 jdk1.8.0_65drwxr-x--- 2 root root 1000 Sep 2 03:41 logs

8. Synthesize the container volume mentioned above to test the release of the web service

In the future, you can publish the version in / volume/test on the host, and the specific test will be brief.

[root@t-docker tomcat9] # cd / volume/test

[root@t-docker test] # mkdir WEB-INF

[root@t-docker test] # cd WEB-INF/
