When I run the shell script to perform the Elastic installation, under a non-root account, I continue to get the following No such file or directory error message:

That's odd, it's failing on the last of these 4 lines:

        tmp_dir = "/elastic_cloud_apps/bootstrap-initiator/bootstrap_initiator/prerequisite/tmp"
        call(["rm", "-rf", tmp_dir], stderr=DEVNULL, stdout=DEVNULL)
        call(["setuser", ece_user, "mkdir", "-p", tmp_dir], stderr=DEVNULL, stdout=DEVNULL)
        uid = getpwuid(stat(tmp_dir).st_uid).pw_name

So for some reason setuser YOUR_USER mkdir -p /elastic_cloud_apps/bootstrap-initiator/bootstrap_initiator/prerequisite/tmp has (silently) failed.

I'd probably try something like docker run -it elastic-cloud-enterprise bash

and then see what happens when you run the setuser ... mkdir ...?

I don't have setuser command on this particular image, but I did manually create the /elastic_cloud_apps/... directories and verified the permissions are owned by the non-root user performing the install. The same error is displayed after manually creating the folder structure

adam.gantt_va · May 7, 2020, 3:38pm

Looking a little more at your comment, since I don't have setuser command on my RHEL image, is there a way to refactor that call? When I search the install script, I don't see those lines in my version of the script.

Alex_Piggott · May 7, 2020, 4:07pm

Sorry - setuser should have been called within the docker -it ... bash session, ie you shouldn't need it in your RHEL

What steps exactly did you take?

adam.gantt_va · May 11, 2020, 2:35pm

Running the setuser command in the docker image provided a user not found message for the user in my image.

Here are the steps I took:

Alex_Piggott · May 15, 2020, 5:13pm

Hey sorry for the delay

Ah I think you should do

docker run --env UID=`id -u` \
      --env GID=`id -g` \
   -it docker.elastic.co/cloud-enterprise/elastic-cloud-enterprise:2.5.0 bash

usermod -u 1005 elastic
groupmod - g 1006 elastic
setuser elastic mkdir -p /elastic_cloud_apps/bootstrap-initiator/bootstrap_initiator/prerequisite/tmp

adam.gantt_va · May 22, 2020, 3:14pm

Successfully ran the commands you provided,

[root@7f80107a671e /]# groupmod -g 1006 elastic
[root@7f80107a671e /]# setuser elastic mkdir -p /elastic_cloud_apps/bootstrap-initiator/bootstrap_initiator/prerequisite/tmp
[root@7f80107a671e /]# ls /elastic_cloud_apps/bootstrap-initiator/bootstrap_initiator/prerequisite/tmp/
README.md

Logged out of the bash session and ran the elastic setup script again, same error message.
