h1. Common operations on X-as-a-Service 

 h2. Matrix-as-a-Service 

 h3. Contact customer for setup informations 

 Do not forget to replace @$CUSTMER@! 

 Hello $CUSTOMER, 

 I will deploy your Matrix homeserver and need a few configuration details from 
 you. I do not know how familiar you are with Matrix or technical terms: 
 do not hesitate to tell me if I go to fast or to slow for you. 

 First of all, each Matrix homeserver is linked to domain name (you users will look 
 like `@username:domain.tld`) for federation. I can offer you two options here, 
 but remember that the chosen domain name cannot be changed afterward: 

   * Your own domain (e.g. domain.tld). 
   * One domain controlled by ungleich (e.g. $, 

 Secondly, I will deploy a Riot web matrix client for convenience (you can use 
 the desktop or smartphone clients as well) and need a domain for that as well: 

   * Your own domain (e.g. matrix.domain.tld) 
   * One domain controlled by ungleich (e.g. matrix.$ 

 Lastly, I will configure the Matrix homeserver for you. You can ask us to set 
 any configuration option but we at least need to know your preferences in term 
 of registration: 
   * Should it be backed by an existing user directory (LDAP)? 
   * Should registrations be filtered by domain of email address? (e.g. anyone 
     with a @domain.tld email address can register). 
   * Should anyone be allowed to register? 

 Feel free to ask me any matrix-related question, as I am a heavy matrix user 

 Best Regards, 



 h3. Deploy new MaaS instance 

 WIP TODO -> ask @fnux for now. 

 * Contact customer to get configuration details (this might take some time => do it first). Allocate ONE VM. 
 * Allocate VM in OpenNebula, based on Debian 10 (IPv6Only). Add HDD storage. 
 * Attach HDD storage to created VM (Help: [[Common operations at DCLIPv6OnlyHosting]]). 
   - Create EXT4 filesystem: @mkfs.ext4 $DEVICE@ 
   - Add FSTAB entry for /var /var/ on $DEVICE. 
     - Get UUID with @blkid@. 
     - Should look like: @UUID=$MY_UUID         /var      ext4      errors=remount-ro         1         2@ 
     - Mount HDD 
 * mount data disk on /mnt. 
     - Move content of /mnt 
 * mv /var to /mnt. 
     - Unmount data /mnt 
 * remove /var; mount -a to remount /var to on new disk from /mnt. 
     - Mount data disk 
 * reboot to /var with @mount -a@ (uses configuration in /etc/fstab). 
     - *Reboot* and make sure that /var is properly mounted. 

 everything's OK. 
 * Upgrade VM: update/upgrade. 
 * Add DNS entry in 
 * Add server to matrix-as-a-service manifest, deploy 
 * Have customer configure his domain. 
 * Create initial admin use.
