⁠Minified Docker image with Tomcat, Java with unlimited JCE patch applied

⁠Usage

Some indications:

• Tomcat installation directory is /opt/tomcat ($TOMCAT_HOME/$CATALINA_HOME). Executable scripts are found in directory $TOMCAT_HOME/bin and the application base (appBase) directory is $TOMCAT_HOME/webapps.
• The path of file catalina.out is managed by the variable $CATALINA_OUT, and its value by default is /dev/null (disabled).
• Apache logs are written into directory /logs/.

There are two ways to use this image:

1. Use it as base image for other images. For example:

FROM thimico/alpine-tomcat

1. Use the image directly, and copy the .war files directly into the appBase directory. For example:

docker run -it --rm thimico/alpine-tomcat /opt/tomcat/bin/catalina.sh run
docker cp ./sample.war tomcat-ci:/opt/tomcat/webapps/sample.war
