Apache Tomcat 8.5.32

A simple docker build for installing a vanilla Tomcat 8.5.32 below /opt/tomcat. It comes out of the box and is intended for use for integration testing.

During startup a directory specified by the environment variable DEPLOY_DIR (/deployments by default) is checked for .war files. If there are any, they are linked into the webapps/ directory for automatic deployment. This plays nicely with the docker-maven-plugin and its 'assembly' mode which can automatically create Docker data container with Maven artifacts exposed from a directory /deployments.

Features:

• Tomcat Version: 8.5.32
• Java Base Image: fabric8/java-centos-openjdk8-jdk:1.5.1
• Port: 8080
• User admin (Password: admin) has been added to access the admin applications /host-manager and /manager)
• Documentation and examples have been removed
• Command: /opt/tomcat/bin/deploy-and-run.sh which links .war files from /maven to /opt/tomcat/webapps and then calls undefined run
• Sets -Djava.security.egd=file:/dev/./urandom for faster startup times (though a bit less secure)

Debugging

You can enable remote debugging by setting JAVA_DEBUG to any value:

• JAVA_DEBUG If set remote debugging will be switched on
• JAVA_DEBUG_PORT Port used for remote debugging. Default: 5005
