#Apache Tomcat 8 running on Oracle Java 8

This is the first version of a Docker container with Apache Tomcat 8 and Oracle Java 8 on Debian Jessie.

APR is not yet configured!

To build run:

sudo docker build -t tomcat8 .

Remember: Tomcat has many hooks for configuration and you should definitely use them!

To launch tomcat:

sudo docker run -d --name tomcat8 -p 8080:8080 tomcat8

To adjust the launch parameters:

sudo docker cp tomcat8:/opt/tomcat/bin/catalina.sh ./

Edit catalina.sh. Adjust memory etc. according to you needs, and NO the defaults are NOT okay. You need to test is with tools like VisualVM. You need to adjust tomcat accordingly. It totally depends on you application.

Stop and remove the running container and then start the container with your customized catalina.sh mounted:

sudo docker run -d --name tomcat8 -p 8080:8080 -v `pwd`/catalina.sh:/opt/tomcat/bin/catalina.sh tomcat8

I recommend that you do the same for

/opt/tomcat/webapps
/opt/tomcat/conf
/opt/tomcat/logs

You can then start the container like this:

sudo docker run -d --name tomcat8 -p 8080:8080 \
            -v `pwd`/catalina.sh:/opt/tomcat/bin/catalina.sh \
            -v `pwd`/webapps:/opt/tomcat/webapps \
            -v `pwd`/conf:/opt/tomcat/conf \
            -v `pwd`/logs:/opt/tomcat/logs \
            tomcat8        

You can now point your browser to http://localhost:8080/. When you like to change some of your configuration simply stop the container:

sudo docker stop tomcat8

Change whatever you like and start the container again:

sudo docker start tomcat8
