Bug 1648921

Ran on puddle 2018-11-27.1

[stack@undercloud-0 ~]$ rpm -q openstack-tripleo-validations
openstack-tripleo-validations-9.3.1-0.20181008110752.4064fb7.el7ost.noarch



Got another error:

Task 'Get the open_files_limit value' failed:
Host: controller-1
Message: Command `docker exec -u root -it mysql ulimit -n` exited with code: 1: non-zero return code

stderr:
    Error response from daemon: No such container: mysql

Task 'Get the open_files_limit value' failed:
Host: controller-0
Message: Command `docker exec -u root -it mysql ulimit -n` exited with code: 1: non-zero return code

stderr:
    Error response from daemon: No such container: mysql

Task 'Get the open_files_limit value' failed:
Host: controller-2
Message: Command `docker exec -u root -it mysql ulimit -n` exited with code: 1: non-zero return code

stderr:
    Error response from daemon: No such container: mysql

Failure! The validation failed for all hosts:
* controller-0

* controller-2

I got a different error:

Task 'Get the open_files_limit value' failed:
Host: overcloud-controller-0
Message: Command `docker exec -u root -it mysql ulimit -n` exited with code: 1: non-zero return code

stderr:
    the input device is not a TTY

Failure! The validation failed for all hosts:
* overcloud-controller-0


When running the command manually you get:
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"ulimit\": executable file not found in $PATH"

The validator still fails.

The execution from GUI:

Task 'Get the open_files_limit value' failed:
Host: controller-0
Message: Command `docker exec -u root mysql /bin/bash -c ulimit -n` exited with code: 1: non-zero return code

stderr:
    Error response from daemon: No such container: mysql

Task 'Get the open_files_limit value' failed:
Host: controller-1
Message: Command `docker exec -u root mysql /bin/bash -c ulimit -n` exited with code: 1: non-zero return code

stderr:
    Error response from daemon: No such container: mysql

Task 'Get the open_files_limit value' failed:
Host: controller-2
Message: Command `docker exec -u root mysql /bin/bash -c ulimit -n` exited with code: 1: non-zero return code

stderr:
    Error response from daemon: No such container: mysql

Failure! The validation failed for all hosts:
* controller-0
* controller-1
* controller-2

****Also from CLI the validator fails:
