KAR Docker Images

To avoid reaching GitHub every time the OpenNMS Core container starts to install ALEC, the Cortex TSS plugin or other plugins,the idea is to create a place-holder container, meaning a container that has no functionality but contains the appropriate KAR file.

The idea is to use this container within the initContainers section of the OpenNMS StatefulSet to copy the KAR file to the $OPENNMS_HOME/deploy directory at runtime.

Compilation

cd alec
make

If you want to build for a specific version, provide a GitHub release reference on the command-line, like:

make RELEASE=tags/v2.0.1

Publishing

make RELEASE=tags/v2.0.1 push

Usage

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: onms-core
...
      initContainers:
      - name: alec
        image: opennms/alec:v1.1.1
        imagePullPolicy: IfNotPresent
        command: [ cp, /plugins/opennms-alec-plugin.kar, /opennms-deploy ]
        volumeMounts:
        - name: deploy
          mountPath: /opennms-deploy
...
      containers:
      - name: onms
      ...
        volumeMounts:
        - name: deploy
          mountPath: /opt/opennms/deploy
...
      volumes:
      - name: deploy
        emptyDir: {}
