Elastic Cloud Enterprise Installer

Start setting up a new Elastic Cloud Enterprise installation by installing the software on your first host.

This first host becomes the initial coordinator and provides access to the Cloud UI, where you can manage your installation.

To learn more about the options you can specify, see the documentation.

NOTE: If you want to add this host to an existing installation, please specify the --coordinator-host and --roles-token flags

What are the permissions on /mnt/data/elastic (and /mnt, /mnt/data)? Normally this happens when the installing user (elk?) can't write to /mnt/data

(Am I reading correctly that elk is a member of the user dockerroot's "personal" group? I think that's harmless but is there a reason for that?)

HI Alex thank for the response and help.

sorry I copied this quickly and didn't include what this output was.

ll /mnt/data/elastic
drwxrwxrwx. 2 ansible ansible 6 Apr 26 23:58 elastic

/mnt
/mnt/data
/mnt/data/elastic

are all ansible and 777 permissions.

ansible is id 1000 and thats why its used.
elk is part of dockerroot just for troubleshooting.
docker group was created manually

OK I think I understand ... the permissions of the /mnt/data and children should be for the user the install script is run as. The id 1000 is just the default but any id can be used

So I'd delete /mnt/data and recreate as per the docs: (eg https://www.elastic.co/guide/en/cloud-enterprise/2.2/ece-configure-hosts-trusty.html)

sudo install -o $USER -g $USER -d -m 700 /mnt/data
sudo mount /dev/xvdg1
sudo chown $USER:$USER /mnt/data
sudo install -o $USER -g $USER -d -m 700 /mnt/data/docker

where USER would be elk

will give it a shot !
