Build strimzi from source

[bitvijays]

o/ Thank you for the support. Trying to build the strimzi from source. Currently, getting the below error:

[INFO] Running io.strimzi.operator.common.operator.resource.NodeOperatorIT

As suggested, For the NodeIT, you might need to adjust the pod CIDR to the one of your cluster. Is there more information how we can do that?

Have setup the Kubernetes Cluster by using sudo kubeadm init --pod-network-cidr=10.244.0.0/16

Came across How to make the pod CIDR range larger in Kubernetes and Change the pod CIDR in Kubernetes Cluster which uses calicoctl

Is this all the errors you get even when running the test manually? I would expect there to be some exception. For example, if the CIDR really is your problem, you should see something like this:

There can be also all kind of other issues while this can fail.

Also, if all you want it just to build Strimzi, you could also skip the tests by exporting MVN_ARGS="-DskipITs" or MVN_ARGS="-DskipTests" before running make all.

Command MVN_ARGS="-Dmaven.javadoc.skip=true -DskipITs -DskipTests" make all can be successfully built
