  * Good understanding of eMagiz runtimes in general

--In the current 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.
++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.
--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.

++In the below section the Windows and Linux variants are described in terms of how to prepare the server to allow the eMagiz Deploy agent to be installed. That agent allows to download images from the eMagiz infrastructure.
  == 3. On-premises deployments ==
  ===3.1 General requirements===
  These are the general requirements to allow the installation of the eMagiz Docker agent:
++* Ensure access to the following URLs is enabled
++    ** registry.emagiz.com:8443
++    ** controlplane.emagiz.com:8000
++    ** Preferably the entry should be *.emagiz.com
--{{info}}It is advised to use Docker version 29.1.3 as this is the version being used in the latest eMagiz cloud template. We advise to align the on-premise Docker version and update it according to the release notes of the [[Cloud templates>>doc:Main.Release Information.Cloud Templates.WebHome||target="blank"]].
--{{/info}}
++===3.2 Installation requirements Linux===
++Whenever Linux is selected as operating system, the latest version of Ubuntu will work. Other Linux distributions will also work such as Debian or Red Hat.
++**Step 1: Install linux distribution**
++Follow all steps in section 3.4

++The steps below will install a linux subsystem under Windows. In that Linux system, Docker and Java will be installed. Please note that the Windows server needs to be able to run Virtualized (either via BIOS setting or via Nested Virtualization).
--==== 3.2.1 Uninstall old versions ====
--{{info}}Before you can install Docker Engine, you need to uninstall any conflicting packages.
++**Step 1: Install linux distribution**
--Your Linux distribution may provide unofficial Docker packages, which may conflict with the official packages provided by Docker. You must uninstall these packages before you install the official version of Docker Engine.{{/info}}

++**Step 2: Configure linux system**
++Please see section 3.4 for these these steps
++
++**Step 3: Update wsl config file **
++In this step we need to add or update the WSL config file that manages the resources of the Linux subsystem. Important resources to manage are the assigned memory and number of processors. For memory we recommend to review the mempory settings for the runtime that need to run on this server and add 762 MB to the total value of the heap and non-heap of these runtimes. For processor we recommend to set the value to 2 - depending on the amount of processors available on that machine
++
++First, locate the config file or add it to the location %USERPROFILE%. The name should be .wslconfig (no extension)

--== 4. Key takeaways ==
--
  * 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
  * eMagiz has a specific agent that manages the download of that image to the on-premises server
  * 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.
