That agent allows to download images from the eMagiz infrastructure.

Once the right installation is done, refer to section 3.7 for the installation of the eMagiz agent that manages the interaction with the eMagiz platform.

52 +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

161 + ** Restart windows
162 +* Download a ubuntu server 18.04 (https://releases.ubuntu.com/18.04/ubuntu-18.04.6-live-server-amd64.iso )
163 +* Create a VM in HyperV.
164 + ** 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).
165 + ** Configure a virtual switch.
166 + ** Add a virtual Hard Disk with proper sizing (e.g. 30 GB)
167 + ** Install an operating system from bootable CD/DVD, ISO file
168 +* Install ubuntu downloaded previously on the VM
169 +* Install docker as per official ubuntu documentation (See https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository) on the VM
170 +* Go to the next section around installing the eMagiz agent

68 68  * 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
69 69  * eMagiz has a specific agent that manages the download of that image to the on-premises server
70 70  * 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.
