I've got errors as below during building nauta on kubernetes pod system as build system.

This system info about Docker container, actually k8s on nauta.

• Nauta version and commit: (nctl version)(git rev-parse --short HEAD):
  git cloned today(2020/03/10)

Nauta component related with bug: (build system/installer/nctl(cli)/dashboard/documentation/k8s/any of nauta container)

make k8s-installer-build

What is the current behavior?

What is the expected behavior?

Anything else do we need to know:

Is any problem building on container(actually nauta)

Hi, it looks like cached docker layers are not working correctly for some reason (I can build this image without problems when docker cache is not used) - #43 PR should mitigate this issue.

Thank you for your reply.
Would you tell me what I should do to debug this issue?

[mateusz-ciesielski]

Best way would be to simply update nauta's code to latest version (PR that I've mentioned above is already merged) and run the build again, nauta/rpm/python should work now

I built nauta on bare-metal successfully, but I failed on Kubernetes pod,
error message is below, it reads that it could not download nginx from mirror site.
But I downloaded it easy by using command "wget http://nginx.org/packages/mainline/centos/7/x86_64/RPMS/nginx-1.13.9-1.el7_4.ngx.x86_64.rpm"

What can I do? or Is it impossible to build on kubernetes pod?

error message partial ---
Trying other mirror.\n

Thank you,

Could you tell me what particular image build is failing? If you mean that you want to build Nauta on some Kubernetes pod (like running make k8s-installer-build inside of Kubernetes container), be aware that it may not work, we are not supporting such case. Although, error message suggests that it is a network related error, so I'd recommend checking if proxy settings are configured correctly (see: https://intelai.github.io/nauta/installation-and-configuration/How_to_Build_Nauta/HBN.html#proxy-setting-requirements).

Thank you for your reply,
I tried to build on kubernetes pod made on Nauta cluster.
I intended to test most of my jobs on Nauta nodes.
If the Nauta build is not supposed to be run on container, I will not try any more.
That's not problem. I just tested.
I will try to test others including deep learning training.
I really appreciate your reply and help. It was very helpful.
I am testing more, and asking more.
Thank you very much.
