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.
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 portainer 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.

82 +=== 3.5 Installation agent ===
83 +
84 +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.
