11 11  == 2. Key concepts ==
12 12  In the new runtime architecture of eMagiz, Docker technology is used to deploy runtimes. eMagiz creates specific runtime images that contain the eMagiz runtime, and can be deployed in dockerized environments.
13 13  
14 -In the below section the specific operating systems and versions are discussed in a sense that the prerequisite installations are described. Once the right installation is done, refer to section 3.5 for the installation of the eMagiz agent that manages the interaction with the eMagiz platform. That agent will download the created docker images that will be deployed in the Docker environment.
14 +In the below section the Linux variant is described in terms of how to prepare the server to allow the [[eMagiz Deploy Agent>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.eMagiz Runtime Management.intermediate-runtime-management-deploy-agent.WebHome||target="blank"]] to be installed. That agent allows to download images from the eMagiz infrastructure.

84 -=== 3.7 eMagiz Docker agent installation ===
85 -
86 -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 when the machine is used for the first time deployment of eMagiz runtimes. A popup will appear that displays the commands per type of OS. Once that agent is installed, the image that is generated for every eMagiz release can be downloaded and installed in the Docker instance.

98 -* 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
99 -* eMagiz has a specific agent that manages the download of that image to the on-premises server
100 -* 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.
