existdb-docker

This is an eXist DB docker image build on top of an eclipse-temurin:17-jre image.

About this image

This image is inspired by davidgaya/docker-eXistDB but adds adjustments to configuration files for development and production purposes.

Second, it is designed to work with TEI files in general—and with the WeGA-WebApp in particular—so the default settings in eXist's conf.xml for whitespace handling and serialization reflect this.

How to build

Navigate into the root directory of this repository and enter:

docker build -t existdb --build-arg VERSION=6.3.0 .

available parameters

  • VERSION: The eXist version to use. Defaults to 6.3.0

How to run

docker run --rm -it \
    -p 8080:8080 \
    --name existdb \
    -v /your/path/to/exist-data:/opt/exist/data \
    -v /your/path/to/exist-logs:/opt/exist/logs \
    -e EXIST_ENV=development \
    -e EXIST_CONTEXT_PATH=/exist \    
    stadlerpeter/existdb:latest

available parameters

  • EXIST_ENV: This will toggle the modification of configuration files. A value of "production" will remove most servlets and will deny direct access to the REST interface. Default is "development" which will not alter
  • EXIST_CONTEXT_PATH: The eXist context path. Defaults to /exist, which means you'll find eXist at http://localhost:8080/exist/ but you may change this to simply / and your default app will repond at http://localhost:8080/
  • EXIST_DEFAULT_APP_PATH: the database path to your default app, e.g. xmldb:exist:///db/apps/WeGA-WebApp. This default app will respond directly at the $EXIST_CONTEXT_PATH (while all other apps are still available at /apps/).

passing JVM flags to the container

Use the JAVA_TOOL_OPTIONS parameter to pass any JVM flags to the container. E.g.

JAVA_TOOL_OPTIONS: -XX:MaxRAMPercentage=75.0

This will set the max heap size to 75% of the memory allocated to the Docker container.

setting the admin password

The admin password can be supplied via the $EXIST_PASSWORD environment variable or the equivalent Docker secret $EXIST_PASSWORD_FILE. If none of these variables are set (or both contain empty values) a random password will be generated and echoed to the logs.
