armel/tomcat repository overview

⁠DEPRECATED

The armel⁠ organization is deprecated in favor of the more-specific arm32v5⁠ organization, as per https://github.com/docker-library/official-images#architectures-other-than-amd64⁠. Please adjust your usages accordingly.

⁠Supported tags and respective Dockerfile links

** THESE IMAGES ARE VERY EXPERIMENTAL; THEY ARE PROVIDED ON A BEST-EFFORT BASIS WHILE docker-library/official-images#2289⁠ IS STILL IN-PROGRESS (which is the first step towards proper multiarch images) **

** PLEASE DO NOT USE THEM FOR IMPORTANT THINGS **

This image is built from the source of the official image of the same name (tomcat)⁠. Please see that image's description for links to the relevant Dockerfiles.

If you are curious about specifically how this image differs, see the Jenkins Groovy DSL scripts in the tianon/jenkins-groovy GitHub repository⁠, which are responsible for creating the Jenkins jobs which build them.

⁠What is Tomcat?

Apache Tomcat (or simply Tomcat) is an open source web server and servlet container developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Oracle, and provides a "pure Java" HTTP web server environment for Java code to run in. In the simplest config Tomcat runs in a single operating system process. The process runs a Java virtual machine (JVM). Every single HTTP request from a browser to Tomcat is processed in the Tomcat process in a separate thread.

⁠How to use this image.

Run the default Tomcat server (CMD ["catalina.sh", "run"]):

$ docker run -it --rm tomcat:8.0

You can test it by visiting http://container-ip:8080 in a browser or, if you need access outside the host, on port 8888:

$ docker run -it --rm -p 8888:8080 tomcat:8.0

You can then go to http://localhost:8888 or http://host-ip:8888 in a browser.

The default Tomcat environment in the image for versions 7 and 8 is:

CATALINA_BASE:   /usr/local/tomcat
CATALINA_HOME:   /usr/local/tomcat
CATALINA_TMPDIR: /usr/local/tomcat/temp
JRE_HOME:        /usr
CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

The default Tomcat environment in the image for version 6 is:

CATALINA_BASE:   /usr/local/tomcat
CATALINA_HOME:   /usr/local/tomcat
CATALINA_TMPDIR: /usr/local/tomcat/temp
JRE_HOME:        /usr
CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar

The configuration files are available in /usr/local/tomcat/conf/. By default, no user is included in the "manager-gui" role required to operate the "/manager/html" web application. If you wish to use this app, you must define such a user in tomcat-users.xml.
