The intent of this Operator is to deploy common workloads to establish a performance baseline of Kubernetes cluster on your provider.

Previously the Benchmark Operator didn't properly take advantage of the reconciliation period. Going forward we will make every attempt to utilize the reconciliation period.
Why did we decide to switch to this? Our operator would implement long running tasks, due to the nature of benchmarks.
However, long running tasks blocks the Operator, causing us to delete the Operator and re-create the operator to
un-block it. The benchmarks mentioned above that state Used for Reconciliation, no longer have this issue.
These two bencharmks are written in a way that doesn't allow for reconciliation to be implemented. To take advantage of the reconciliation loop, these two benchmarks need to be rewritten.
Optional locations for workload images can now be added easily without the need to rebuild the operator. To do so in the workload args section of the CR add image: [location]
NOTE: This is not a required arguement. If omitted it will default to the currently verified workload image. Additionally, this is not enabled for YCSB
For Example:
apiVersion: ripsaw.cloudbulldozer.io/v1alpha1
kind: Benchmark
metadata:
name: example-benchmark
namespace: my-ripsaw
spec:
elasticsearch:
server: "my-es.foo.bar"
port: 9200
metadata_collection: true
cleanup: false
workload:
name: "foo"
args:
image: my.location/foo:latest
