OpenNebula is not running or there was a server exception.

I deployed OpenNebula in VMware using Docker Compose. After I finish configuring passwordless SSH, OpenNebula cannot function properly. When I try to login the front-end, there is the error message “OpenNebula is not running or there was a server exception. Please check the server logs.”
I check “docker ps” and find that “opennebula-opennebula-mysql-1” is “unhealthy” status. Then I check the logs of “opennebula-opennebula-mysql-1”. It is in a loop that “mysqld” is entered and is stopped.

Versions of the related components and OS (frontend, hypervisors, VMs):
OS: CentOS-7
Opennebula Version: 6.0

OpenNebula 6.0 is no longer supported. Check out the 6.8 version or if you need CentOS7 (which is no longer supported on newer versions) try the 6.4 LTS version.

Thanks for your reply! Due to the ease of management of the Docker deployed cluster, I would like to use Docker to deploy the OpenNebula cluster. Currently, I have only found 6.0 version that can be deployed using Docker. Can I use Docker to deploy a newer version of OpenNebula?
Looking forward to your reply.

Can I use Docker to deploy a newer version of OpenNebula?

That depends on whether someone releases and maintains docker images for such purpose. This being said, there are limitations when running OpenNebula inside a container, take a look at the warning here. If you are looking for ease of cluster setup there are several options

  • minione: this is very good to bootstrap a frontend + node cluster and try it out. Possibly grow from there.
  • one-deploy: use ansible to deploy your cloud according to your requirements
