We have an EC2 inside Autoscaling Group (1 instance at a time) with Cloud_init / Cfn_init script to build up.
We mount an ElasticFileSystem where we have data and plugins directories to have persistent volume even if EC2 is recreated.
grafana.ini config file is changed before grafana-server is started during user data script execution.
Since yesterday we were using a 7.1.something version, and everything was working fine, Datasources, Dashboards were still present when recreated or updated.
Yesterday, version 7.4 latest with:
yum install -y grafana
And it seems that now, grafana.db file is recreated and I need to manually recreate Datasources and import Dashboards as json (fortunately we have them stored on a gitlab project).
I would avoid having to use the provisioning if having a persistent volume is sufficient.
Any ideas what could be causing this behaviour ?
Thanks a lot
