Cannot create a SeldonDeployment having volumes of type projected and configMap.

[sumeetgajjar]

Seldon version: v0.4.1

If SeldonDeployment is created with volumes of type projected and configMap it fails stating the following message

kubectl failed exit status 1: Error from server (InternalError): Internal error occurred: Internal error occurred: Unable to access invalid index: 2

In order to reproduce the error use the following yaml

Can you try with the latest 0.5.1-SNAPSHOT from master?

[sumeetgajjar]

I tried the same with 0.5.1-SNAPSHOT, it fails.
But this time it fails giving the following error message.

validation failure list: type in spec.predictors.componentSpecs.spec.volumes.downwardAPI is required type in spec.predictors.componentSpecs.spec.volumes.projected.sources.configMap is required

[ukclivecox]

That is strange. You would need to reinstall Seldon or at least the CRD for this to work. Did you do that or just update the image of the manager?

[sumeetgajjar]

Turns out, the CRD was not updated.
After updating the CRD, everything works!!!

Thank you for the suggestion. 😄
