Description Sergio 2020-12-04 14:30:34 UTC 
Description of problem:
When we deploy MTC, the log-reader pod is created and then instantly crashes. It shows "exec format error" in the pod's log.

Version-Release number of selected component (if applicable):
MTC 1.4.0

How reproducible:
Always

Steps to Reproduce:
1. Install MTC 1.4.0 using 72b089c1a985294b9161651ca8baef69646bdbc7901f9176349ef31c41e44840 sha to deploy log-reader pod.


Actual results:
The log-reader pod crashes

]$ oc get pods
NAME                                   READY     STATUS             RESTARTS   AGE
migration-log-reader-fb9587f5d-72mcv   0/2       CrashLoopBackOff   38         1h


$ oc logs migration-log-reader-fb9587f5d-72mcv  -c plain
standard_init_linux.go:178: exec user process caused "exec format error"


Expected results:
The log-reader pod should work without errors.

Additional info:

 It seems that the entry point has no shebang #!/bin/sh and it is causing the issue.
