That agent allows to download images from the eMagiz infrastructure.

80 +=== 3.5 Installation agent ===
81 +
82 +eMagiz needs to install a specific agent in the Docker instance that allows to download runtime images that needs to be installed on the Docker instance. The specific command to run inside the Docker instance is specific for the machine that is configured inside eMagiz Design & Deploy Architectures. It can be found inside the eMagiz iPaaS portal or is available upon request. Once that agent is installed, the image that is generated for every eMagiz release can be downloaded and installed in the Docker instance.

92 +* eMagiz uses runtime images to deploy emagiz runtime on dockerized environments. The runtime image holds all the information and components required to run the runtime
93 +* eMagiz has a specific agent that manages the download of that image to the on-premises server
94 +* The firewall of the on-premises environment should allow outgoing traffic without any restriction. In case that is not desirable, eMagiz can provide the addresses and ports needed to setup the right firewall rules.
