ApiVersion not set, kind not set while SAP Data Hub installing

[former_member592211]

Hello there

I'm trying to install sap data hub ond my demo landscape.

I have a master server with: Centos 7, 64 GB Memory, 4 cores and 128 GB harddisk.

3 Nodes with: Centos 7, 64 GB Memory, 4 cores and at least 64 GB harddisk.

On all Servers I'm useing Kubernetes version: 1.10.0, Docker version: 17.03.0-ce, Helm version: 2.9.1

All pre-flight checks went without any error.

But if I accept the installation properties the installation instand print an error out and exited.

Hope you can help me

Cheers

Miguel

Hi,

which kubectl version are you using? If it is 1.10.0, then switch to 1.10.1 (https://help.sap.com/viewer/e66c399612e84a83a8abe97c0eeb443a/2.3.latest/en-US/79724de552db4b2b81c4a893f2c7ed18.html)

Cheers

Hello Thorsten

Thanks for your answer wit the kubectl version 1.10.1 has it worked.

But now I get an other error on my pods.

It seems like my nodes in my cluster cant pull images from my registry.

Do you have an idea how to fix it.

I get this error on my kubernetes dashboard from my hana-0 pod.

Regards

Miguel

On the nodes where you have docker installed edit/create the /etc/docker/daemon.json and add the following:

{ "insecure-registries":["sapdh01:5000"] }. This should solve the issue. You probably have to restart the docker service.

Thank you pascaldp that resolved my issue. 🙂

I know this is a bit dated, but for anyone else stumbling here. This was a known bug in Kubernetes 1.10.0. Fixed in 1.10.1 and above:

This looks like a permissions issue. Is the installer process able to read from all of the install directories? Are you able create/update secrets with the Kubernetes user being used to deploy DH?
