Not working with LibreOffice

[amosaini]

Summary

What happened/what you expected to happen? I am need to use libreoffice headless to convert docx file to pdf. This is working execellent in Vanilla k8s and Databricks but when i do the same in Kubeflow which uses argo workflow at its backend it does not produce any output.

What version are you running? argoproj.io/v1alpha1 Kubeflow 1.4

Diagnostics

Paste the smallest workflow that reproduces the bug. We must be able to run the workflow.

This is the yaml I am using. I am then manually copying the input files

kubectl cp ./288.pptx libreoffice-bash:/tests/
kubectl cp ./dummy.pptx libreoffice-bash:/tests/

This is working but when I tries to do the same in Kubeflow it doesn't was. The script executes without producing any output file.

Output :

ignore the error here. I was also getting this in vanilla k8s but it gives the output there.

I switched to docker runtime it works there.

[alexec]

Docker executor is no longer supported. If this does not work with PNS executor, then this is a regression. Have you tried PNS?

[alexec]

Can you please upload the workflow that caused this problem.

[amosaini]

I just tried it with PNS executor. It is succeeding with the PNS executor. I will get back to you with the argo workflow.

Output of the wf with pns executor:

The above workflow is simply using LibreOffice Headless to convert pptx into pdf. I saw the logs for LibreOffice as well. It has frequent SIGINT, SIGTERM system calls. I am thinking that the emissary executor sends different or new interrupts to processes that apps (in our case LibreOffice) cannot handle. Does the emissary executor kill some kind of thread on its own as well?

[alexec]

Thank you. Have you tried :latest?

[amosaini]

:latest with libreOffice.? yeah https://hub.docker.com/r/linuxserver/libreoffice#! this was the official one I tried to run on. Same issue there as well.

[alexec]

No, argoproj/argoexec:latest.

[amosaini]

Let me just try that and I will get back to you after the execution. It would help to speed up the process if you could tell me where to add it exactly.

[amosaini]

I changed gcr.io/ml-pipeline/argoexec:v3.1.6-patch-license-compliance to argoproj/argoexec:latest and executor to emissary now the pipeline is throwing Error (exit code 2): unexpected end of JSON input. Screenshot attached.

libreoffice_fail_stack (1).txt log trace of libreoffice.

[alexec]

You need to run latest controller too.
