+# Initial Infrastructure Setup
+
+This document describes the steps needed for the initial infrastructure setup (in case everything needs to be bootstrapped from scratch)
+
+This would be the sequence the systems need to be set up:
+- lx-boot-xx (boot.psi.ch, boot-dmz.psi.ch)
+- lx-repos-xx (repos.psi.ch, repos-dmz.psi.ch)
+- lx-sysdb-xx (sysdb.psi.ch)
+- lx-puppet-xx (puppet.psi.ch)
+
+The steps involved to bootstrap the boot server and the repository server are the following:
+
+1. Create the VM in vcenter (Make sure secure boot is disabled!)
+1. Get the latest RedHat RHEL iso from somewhere (i.e. ETH Redhat Satellite)
+    - There are two ISOs, one ~900MB and one ~11GB (RHEL8). The smaller one is able to boot and start the installation of the system, however it requires a network based repository for the installation (i.e. the content of the unpacked ISO need to be available via http(s))
+    With the bigger one the system can be completely installed.
+
+1. Generate a kickstart file for the system in the https://git.psi.ch/linux-infra/bootstrap repository
+    - For the DMZ server the ip of the DNS server needs to be different in DMZ `--nameserver=192.168.70.5`
+
+1. Create a new iso including the generated kickstart file via
+    ```
+    mkksiso lx-boot-dmz-01.psi.ch.ks rhel-8.7-x86_64-boot.iso  lx-boot-dmz-01-rhel-8.7-x86_64-boot.iso
+    ```
+
+1. Remote Login (via RDP) to vmsmgt.psi.ch and mount the ISO to the VM
+
+    1. Make the generated iso accessible to the machine vmsmgt.psi.ch
+
+    1. Open vcenter.psi.ch in the browser, search the virtual machine you want to mount the ISO to. Click on __Launch Remote Console__
+    ![](launch_remote_console.png)
+
+    1. This will open the VMWare Remote Console program. To mount the ISO do the following:
+        ![](mount_iso_menu.png)
+        ![](mount_iso.png)
+
+    1. Start the VM to trigger the install
