Additional tags are provided:
- tags containing a
-SNAPSHOTpostfix are development artifacts (from the master branch). Do not use them in a production environment. - tags without any postfix are release artifacts
There are several environment variables available to tweak the behaviour. While none of the variables are required, they may significantly aid you in using these images. The variables are read by an init script which further sets JAVA_OPTS variables to be used in tomcat's templated configuration file server.xml.
Environment variables:
| Variable | Default | Java variable |
|---|---|---|
| TOMCAT_PORT | 8080 | -DTOMCAT_PORT |
| TOMCAT_PORT_SSL | 8443 | -DTOMCAT_PORT_SSL |
| TOMCAT_AJP_PORT | 8009 | -DTOMCAT_AJP_PORT |
| TOMCAT_SERVER_PORT | 8005 | -DTOMCAT_SERVER_PORT |
| TOMCAT_MAX_HTTP_HEADER_SIZE | 32768 | -DTOMCAT_MAX_HTTP_HEADER_SIZE or -DMAX_HTTP_HEADER_SIZE |
| TOMCAT_MAX_THREADS | 200 | -DTOMCAT_MAX_THREADS or -DMAX_THREADS |
| TOMCAT_ACCESSLOG_ROTATE | true | -DTOMCAT_ACCESSLOG_ROTATE |
| TOMCAT_ACCESSLOG_MAXDAYS | -1 | -DTOMCAT_ACCESSLOG_MAXDAYS |
| TOMCAT_LOGGING_MAXDAYS | 5 | -DTOMCAT_LOGGING_MAXDAYS |

The tomcat image comes in a few flavors, where the variants use the following tag-structure:
tomcat:<version>[-<java>[-<os>]]
- version: the Tomcat version
- java: the Java distribution and version, for example
jdk-8orjdk-8u272-bionic - os: the Operating System, for example
bionic
In general, the latest update (minor version) of the last few major Tomcat releases are maintained:
9.08.5- Tomcat 8.5 is thought as a replacement for Tomcat 8.0. Tomcat 8.0 is end of life and is not supported.7.0
All the available Tomcat images are built on top of the docker.io/xenit/openjdk images.
Builds are produced by GitHub Actions driving Gradle from a GitHub workflow file.
To build a local version of the tomcat images:
./gradlew buildDockerImage
