Hello there,

I just started to use Rancher and I love it, so after a week of test I decided to deploy it on our qa servers, then on production at OVH, so I just figured aout after a power lost that the rancher server ost all stacks and hosts configured, It just did keep the users information. then it is a normal behaviour? how I can void it?

My configuration:
OS: Ubuntu Server 16.04.1 LTS
8 GB RAM

My server was deployed using a docker-compose file:

version: '2'
services:
  rancher:
    image: rancher/server:v1.1.4
    restart: unless-stopped
    ports:
      - 8080:8080
    environment:
      - CATTLE_DB_CATTLE_MYSQL_HOST=my_mysql_percona_based_server
      - CATTLE_DB_CATTLE_MYSQL_PORT=3306
      - CATTLE_DB_CATTLE_MYSQL_NAME=my_database
      - CATTLE_DB_CATTLE_USERNAME=my_user
      - CATTLE_DB_CATTLE_PASSWORD=my_password
    network_mode: bridge

So I reviewed the database just to be sure that the configuration of hosts was saved and there exists, but isn’t fetched by the server after a restart.

I hope some one can help me with this and thanks in advance,

Oscar.

All the persistent state is in the database… Are you sure you’re not looking at the wrong environment? It doesn’t really make sense that auth would be configured but all the other info was lost.

Thank you for your reply,

I figured out that all the issue was related with the environments. I was looking in the wrong place and I can say that my issue was solved.

Just a sugestion, please add an officia procedure to migrate the rancher server to another host, because I tried it and all my host where messed up. Then Rancher is a terrific product and I want to say thank you for your hard work.

Regards,
