[GitHub] [openwhisk] ajanikowski opened a new issue #4960: [Invoker] Cannot retrieve logs of "user-action" container with pod-template feature

[GitBox <gi...@apache.org>]

ajanikowski opened a new issue #4960:
URL: https://github.com/apache/openwhisk/issues/4960


   ## Description
   Invoker cannot retrieve "user-action" container logs in presence of one or more sidecar container in the pod function. 
   Returned logs are always empty even if the function write on stdout/stderr.
   
   ## Environment details:
   
   * on-cloud deployment on AKS
   
   ## Steps to reproduce the issue:
   
   1.   Deploy openwhisk using the pod-template feature to inject a sidecar container:
   1.a Create a ConfigMap like this:
   ```
   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: {{ .Release.Name }}-invoker-template
     labels:
   {{ include "openwhisk.label_boilerplate" .| indent 4 }}
   data:
     podTemplate.yaml: |
       apiVersion: v1
       kind: Pod
       spec:
         - name: "sidecar"
           imagePullPolicy: "IfNotPresent"
           image: "busybox:latest"
           command: [ "/bin/sh", "-c", "--" ]
           args: [ "while true; do echo 'running...'; sleep 30; done;" ]
   ```
   1.b Include the _CONFIG_whisk_kubernetes_podTemplate_ variable into invoker chart _helm/openwhisk/templates/invoker-pod.yaml_
   ```
         ...
         volumes:
         - name: pod-template-dir
           configMap:
             name: {{ .Release.Name }}-invoker-template
         ...      
         containers:
         - name: invoker
         ...      
           env:
             - name: "CONFIG_whisk_kubernetes_podTemplate"
               value: "file:/invoker-template/podTemplate.yaml"
         ...      
   ```
   2.   Run an every function that writes on stdout
   
   
   ## Provide the expected results and outputs:
   
   Logs are not empty using wsk or other trigger method.
