Add a Docker Host to any cloud:

Important

As of Conduit v3.6.2 Ubuntu 14.04 is no longer supported for Docker Hosts OS due to Docker version upgrade to address CVE-2019-5736. Existing Conduit Docker Hosts running on 14.04 will not be able to upgrade to latest Conduit Agent version. All new Conduit Docker hosts using Ubuntu require Ubuntu 16.04 or 18.04.

Add an existing Docker Host

Conduit can manage and inventory existing/brownfield Docker Hosts by using the Manual Docker Host option.

Note

Adding a Docker Host that was previously managed by another Conduit Appliance will disable management of the host on that Appliance as the Conduit Agent settings will be reconfigured.

Note

Container Mode on the Cloud settings where the Host is being added must be set to Conduit for non-Kubernetes/Swarm hosts.
