Minimal Docker image with Apache Tomcat

Basic Docker image to run Apache Tomcat. This is based on Alpine Linux to keep the size minimal.

• Tomcat is installed in /opt/tomcat.
• It listens on port 8080.
• A user admin is configured, with access to the manager and host-manager apps. You should remove it, or at least change its password, if you want to use this image in production.
• Documentation and examples have been removed.

Tags

• tomcat8-java8 or 8 or latest: Tomcat 8 on Oracle Java 8
• tomcat7-java8 or 7: Tomcat 7 on Oracle Java 8
• tomcat6-java8 or 6: Tomcat 6 on Oracle Java 8

Please note that Java 7 is unsupported by Oracle, as of April 2015, so the following tags use Java version 7u80, which has know security issues, and should not be used on a publicly accessible website:

• tomcat8-java7: Tomcat 8 on Oracle Java 7
• tomcat7-java7: Tomcat 7 on Oracle Java 7

Additionally, tags are created for each tomcat release (e.g. 8.0.24 or 8.0.24-java8).

Note that the 7 tag used to reference tomcat7-java7. It now references tomcat7-java8 due to the end of support for java 7.

Usage

Example:

docker run -d -p 8080:8080 jeanblanchard/tomcat:8
