  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.

  ===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
++
++**Step 2: Install eMagiz Deploy Agent**
++Install the eMagiz Deploy agent as can be found in this [[microlearning>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.eMagiz Runtime Management.intermediate-runtime-management-deploy-agent.WebHome||target="blank"]]

++{{info}}Please note that this section also applies to Windows Server 2019 version >1806{{/info}}
++
++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).
++
++**Step 1: Install linux distribution**
++
  {{code language="cmd"}}
++  wsl --install -d Ubuntu
++  sudo apt-get update
++  sudo apt install --no-install-recommends apt-transport-https ca-certificates curl gnupg2
++  . /etc/os-release
++{{/code}}
++
++**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)
++
++{{code language="cmd"}}
++  #Add following lines
++
++  # Settings apply across all Linux distros running on WSL 2
++  [wsl2]
++  # Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MB
++  memory=16GB
++  # Sets the VM to use two virtual processors
++  processors=2
++{{/code}}
++
++
++**Step 4: Auto start the linux subsystem when Windows server restarts **
++
++{{code language="cmd"}}
++* Press Windows+R
++* Type shell:startup and press enter
++* Add or update file start_wsl.bat
++* Add following line into the document and save file
++  * wsl sudo /usr/bin/dockerd

++  ** Go to Server Manager, Manage (top right), enable roles and features, select the desired roles and server selections. In the Features section, enable Hyper-V.
++  ** Restart windows
++* Download a ubuntu server 18.04 (https://releases.ubuntu.com/18.04/ubuntu-18.04.6-live-server-amd64.iso )
++* Create a VM in HyperV.
++  ** For this, choose Generation 1, the amount of memory you want to assign to ubuntu and thus to the containers. Please consider the overhead for memory as well (such as OS).
++  ** Configure a virtual switch.
++  ** Add a virtual Hard Disk with proper sizing (e.g. 30 GB)
++  ** Install an operating system from bootable CD/DVD, ISO file
++* Install ubuntu downloaded previously on the VM
++* Install docker as per official ubuntu documentation (See https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository) on the VM
++* Go to the next section around installing the eMagiz agent

++
++== 5. 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.
