Components

In Rainbow Platform each service is represented by a Component which is instantiated as a docker process in a unique Virtual Machine. Then applications are formed by connecting individuals components (VMs) together.

  • Custom Docker registries are supported.

• The communication protocol is setting by exposing or requiring interfaces, which is the network port that the Component exposes or requires to communicate.

  • A user can select one of the existing interfaces, like a TCP access through port 80, or define a new interface.

  • For the definition of the required interface, an existing exposed interface of another component has to be selected.

• Advanced Options can be set such as run the component image in host mode, priviliged mode, add System Capablities, assign hostname
