Run KEEP with Docker

This section describes how to setup KEEP to run as part of a Docker image. As the image also includes a complete Domino server, it will enable you to run all the KEEP APis, including the ones that require a server instance of Domino.

Please also check this page

While the installation instructions may seem a bit intimidatingly at first, if you follow them carefully they will work. And once a Docker environment has been setup, it is easy to both use and maintain.

Install and prepare Docker

  • Check the official documentation for installing Docker on your OS.
  • Run through a tutorial when you are new to Docker
  • Create a Domino base image using the instructions in the domino-docker GitHub repository. KEEP will build on top of this image

Creating the KEEP image

See Running KEEP with a Docker Image.


Three additional scripts are included in the Docker container.


# Starts the vert.x tasks that talks to Domino
export GodMode=false
export DEBUG=true
export DOMINO_HOME=/opt/hcl/domino/notes/latest/linux
export JAVA_HOME=/opt/hcl/domino/notes/latest/linux/jvm
export NOTESDATA=/local/notesdata
export V_PATH=/opt/hcl/keep/resources:/opt/hcl/keep/classes:/opt/hcl/keep/resources:/opt/hcl/keep/libs/*
export LOG_DIR=$NOTESDATA/logs
[ -d $LOG_DIR ] || mkdir -p $LOG_DIR
# This is important - must be writable -otherwise the docker blows
$JAVA_HOME/bin/java -XX:+HeapDumpOnOutOfMemoryError -XX:+UseG1GC -XX:+UseStringDeduplicationJVM -cp $CLASSPATH -jar projectkeep.jar > $LOG_DIR/vertx.log 2>&1 &

When you installed the expanded version of KEEP (not the fat JAR) the launch line needs to look like this:

$JAVA_HOME/bin/java -XX:+HeapDumpOnOutOfMemoryError -XX:+UseG1GC -XX:+UseStringDeduplicationJVM -cp $CLASSPATH com.hcl.domino.keep.Launch > $LOG_DIR/vertx.log 2>&1 &


# Before she shutdown domino we shutdown KEEP
export ADMINPORT=8889
curl --max-time 10 -d '{"shutdownkey" : "The End is near!!"}' -H "Content-Type: application/json" -X POST http://localhost:$ADMINPORT/shutdown


# After shutdown - kill the Java task if it is still there
pkill -9 -f projectkeep

Debugging with Docker

There is also more Docker documentation available here: Docker Documentation. Some of the information is a bit dated, in particular don’t worry about building your own Docker images as that now happens automatically. Instead focus on the section for setting up a Docker debugging environment.

Creating Docker users and test data

Once you have your Docker image up and running, you’ll need to create test users and test data for the KEEP APIs to run against. You’ll find instructions here: Docker Test Data
