Deprecated. The Docker-based Nimbra Edge Core (connectit install core) is deprecated as of R4.2.0 and will be removed in a later release. It remains supported in R4.2 so that existing installations can be migrated. These pages are kept for existing installations; new installations should follow Get started. To move an existing installation, see Migrate from Docker-based Nimbra Edge.

If you already have a machine to use for this tutorial simply verify it fulfills the hardware requirements. Specifically ensure that the CPU supports SSE4.2 instructions and that there is 16GB memory available.

For optimal operation of Docker-based Nimbra Edge, it’s crucial to run each component on separate instances. These instances can be either physical machines or virtual machines (VMs). However, for the purposes of this tutorial and to simplify the setup, it’s possible to run all components on a single instance.

In a production environment, always ensure that each component is running on a separate instance. Running multiple components on the same instance is not recommended.

Connectivity #

Core needs to be accessible from the public internet. Specifically TCP ports 80 and 443 need to be open, without which the installation will not work.

Video appliances communicate with other appliances over UDP ports 20000-21000 and thus UDP packets to and from that port range needs to be allowed between appliances.
