h1. Bootdisk h2. Requirements https://trello.com/c/to0NYlGk/7-using-discovery-without-dhcp-2 I would like a boot disk option that provides the following: * A single ISO that allows me to provision a system against any configured hostgroup on the Satellite. * The ISO would not require me to pre-create a host in Satellite. * The ISO would allow me to provide a user provided IP address or use DHCP to find the Satellite server. * The ISO will be generated on the Satellite * The ISO will provide a means to provision via a Capsule * The functionality to generate the ISO will be exposed via the API, UI & CLI. * Functionality to provide a local IP and VLAN to the target host h2. Approaches h3. Bootdisk In the bootdisk approach, the Generic bootdisk would be modified to provide a menu like the one shown below: !bootdisk.png! *Notes*: * If the user does not have DHCP, they may configure networking manually. * The provisioning URL can be customized, for example, if DNS is not available and you need to use an IP * If the user wants to build an existing host, they can boot from the existing record * Otherwise they can create an entirely new host If creating a new host, iPXE chainloads off of the Foreman server. *Workflow* They are prompted for a host name: !new_host.png! And then hostgroup, and (if enabled) organization, and location: !hostgroup.png! !org_select.png! !loc_select.png! Finally: * iPXE Boots off Foreman * Foreman creates the new Host, and runs orchestration * Server boots vmlinuz/initrd * Loads kickstart * Provisions as normal *This is ridiculously insecure, because we're running orchestration with access to services like DNS, Realm, Puppet, etc* Options: * Have bootdisk ask for login ** Only supports HTTP (plaintext) ** Foreman if SSL is enabled does not allow HTTP login ** Discovery, in its full RHEL environment, could do this * Tokens ** Have a bootdisk wizard that lets a user generate a bootdisk image with embedded tokens, that give access only to specific host groups/orgs/locations h3.
