<p>I'm trying to install a <a href="https://github.com/spring-cloud/spring-cloud-dataflow-samples/tree/master/custom-dataflow-builds/dataflow-server-25x" rel="nofollow noreferrer">custom built SCDF2.5.1</a>(To add oracle Driver) into openshift (Followed the Kubectl installation doc for SCDF). I modified the deployment.yaml to pull this custom SCDF docker image of mine from git repo. Now when I start the container I get the below error</p>

<p>I saw a thread related to this post where the <a href="https://github.com/spring-cloud/spring-cloud-dataflow-server-kubernetes/issues/323" rel="nofollow noreferrer">fix</a> was provided to spring-cloud-dataflow-server-kubernetes and spring-cloud-dataflow-server-kubernetes-autoconfigure project. But I'm not sure whether thsose changes are available for the custom build 2.5.1 Release. Also I checked my deployment.yaml and the toggle "SPRING_CLOUD_DATAFLOW_FEATURES_SCHEDULES_ENABLED" was set to true. </p>

<p>In deployment.yaml I have removed database service &amp; config, removed the scdf-server config as well, as I added the driver properties in application.properties while building the docker image itself. Below are the deployment.yaml and application.properties file which built into the scdf jar. FYI, removing the scdf-server config from deployment.yaml has no effect on the the failure. The above exception remains same. Also removed the skipper URI.</p>

<p>So what am I doing wrong or missing here? Please advice.</p>

<p>Thanks in advance.</p>

<p>Most likely you are missing task platform configuration <a href="https://github.com/spring-cloud/spring-cloud-dataflow/blob/43247faf52bd48c5e51ece6fdb72520e1c286b01/src/kubernetes/server/server-config.yaml#L35-L41" rel="nofollow noreferrer">server-config.yaml</a> which is part of a k8s deployment files. As you're using your own <code>application.properties</code> file I have a feeling you didn't use that k8s config file.</p>
