I want to deploy NextCloud on Azure Container Instances. I was able to set up the container group using Azure CLI like this:
az container create
--resource-group NextCloud
--name nextcloudcontainer
--image nextcloud
--dns-name-label somelabel
--ports 80 443
--azure-file-volume-account-name myaccountname
--azure-file-volume-account-key myaccountkey
--azure-file-volume-share-name nextcloudfs
--azure-file-volume-mount-path /var/lib/nextcloud/
--os-type Linux
--cpu 1
--memory 2
--location germanywestcentral
--restart-policy OnFailure
Problem is, that the drive /var/lib/nextcloud/ is mounted with permissions 777, but for nextcloud I require 770. This cannot be changed with chmod afterwards, but only at deployment time. How could this be achieved?
I saw this post, but I do not understand, how this could be done as with restart of the container, I would have to do this manually every time.
