Cassandra-docker

Apache Cassandra and Elassandra docker images.

Elassandra

Building Docker Images

Run build.sh in the repository root. This first builds the base-openjre image, which is a Debian Strech image with OpenJRE 8 (headless) installed, and then builds the given distribution and version of cassandra.

For Elassandra, invoke build.sh:

./build.sh elassandra 5.5.0.13

Openshift

The following steps assume that an OpenShift project named myproject has already been created and that the OpenShift client (oc) has been configured to connect to the OpenShift cluster.

Note: The project name (k8s namespace) is used as part of DNS names specified in the Cassandra configuration files. If you use an alternate project name, you'll need to replace all occurances of myproject with the appropriate value.

It is also assumed that the Docker images have already been built and pushed to the local OpenShift Docker registry. See Building Docker Images above.

Create an elassandra-config ConfigMap containing the Cassandra/Elassandra configuration:

oc create configmap elassandra-config --from-file=examples/elassandra/openshift/conf/

Create an elassandra Service:

oc apply -f examples/elassandra/openshift/elassandra-service.yaml

Create the elassandra StatefulSet, which spawns 3 Elassandra nodes:

oc create -f examples/elassandra/openshift/elassandra-statefulset.yaml
