Cannot deploy eck elasticsearch cluster after successful operator install

Elastic Orchestration Elastic Cloud on Kubernetes (ECK)
1

Hi All,

As mentioned I am trying to deploy eck elasticsearch through a manifest install. No helm used.

It is failing on the first init container with the following message:

bash: /mnt/elastic-internal/scripts/prepare-fs.sh: /usr/bin/env: bad interpreter: Permission denied

Here is the elasticsearch yml I am using. I think the issue is that the prepare-fs.sh script is owned by root user and elasticsearch group. I tried playing around with the settings for : "runAsUser: 1000, runAsGroup: 0, fsGroup: 1000"
but no success.

The original file I used before changing to debug the issue is:

btw this might be useful as well:
