Docker not starting after install OneAgent


I have a big problem on one of my our environment.

After installing the oneagent on a host with OpenShift version 3.9 installed, we've a problem with Docker. All processes start correctly but only Docker has errors in logs and don't started.

Error starting daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain: Could not create nat/DOCKER chain: ERROR: object '/opt/dynatrace/oneagent/agent/processagent/lib64/' from /etc/ cannot be preloaded: ignored.

Both files exist. Docker and oneagent are run on the root account.

/The installation is on the Centos Atomic./

  • Selinux is enabled or not?
  • What is your oneagent version?
  • Is it a standard agent deployed on the host, or using image? (I assume it's locally deployed)
  • What is the content of /etc/
  • The path to library '/opt/dynatrace/oneagent/agent/processagent/lib64/' is definitely non-standard. Does this file exist on your host? Default location should be /opt/dynatrace/oneagent/agent/lib64/

    Although I have not experience with CentOS atomic, I don't see a reason why the location should have changed.

Hi @Julius L.

I have information from support that this problem will be fixed in upcoming releases:

  • The issue with Docker has been fixed with agent 1.159.
  • Once Managed 1.160 is released(ETA end of January)


Have a nice day!

Do you know the cause of this issue? Is it somehow related to docker configuration?

Root cause was a change in default SELinux policy, most likely introduced in recent release of CentOS 7.6 Atomic.

SELinux module shipped with OneAgent was adjusted to account for these changes.
