# TuDatTr IaC
## Backups
Backup for aya01 and raspberry are in a backblaze b2, which gets encrypted on the clientside by rclone.
but first of all we need to create the buckets and provide ansible with the needed information.
## Vault
- Create vault with: `ansible-vault create secrets.yml`
- Create entry in vault with: `ansible-vault edit secrets.yml`
- Add following entries: 
  - `vault_pi_tudattr_password: <YOURPASSWORD>` (password you've setup on the device)
  - `vault_aya01_tudattr_password: <YOURPASSWORD>` (password you've setup on the device)
  - `vault_pihole_password: <YOURPASSWORD>` (arbitrary password you want to log in with)
  - `vault_mysql_root_password: <YOURPASSWORD>` (arbitrary password, used internally)
  - `vault_mysql_user_password: <YOURPASSWORD>` (arbitrary password, used internally)
  - `vault_ddns_tudattrdev_password: <YOURPASSWORD>` (password needed for ddns, refer to [here](https://www.namecheap.com/support/knowledgebase/article.aspx/595/11/how-do-i-enable-dynamic-dns-for-a-domain/))
  - `vault_ddns_borgland_password: <YOURPASSWORD>` (password needed for ddns, refer to [here](https://www.namecheap.com/support/knowledgebase/article.aspx/595/11/how-do-i-enable-dynamic-dns-for-a-domain/))

## Server
- Install Debian (debian-11.5.0-amd64-netinst.iso) on remote system
- Create user (tudattr)
- Get IP of remote system (192.168.20.11)
- Create ssh-config entry
  ```config
  Host aya01
    HostName 192.168.20.11
    Port 22
    User tudattr
    IdentityFile /mnt/veracrypt1/genesis
  ```
  - copy public key to remote system
  `ssh-copy-id -i /mnt/veracrypt1/genesis.pub aya01`
- Add this host to ansible inventory
- Install sudo on remote
- add user to sudo group (with `su --login` without login the path will not be loaded correctly see [here](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918754)) and `usermod -a -G sudo tudattr`
- set time correctly when getting the following error
```sh
Release file for http://security.debian.org/debian-security/dists/bullseye-security/InRelease is not valid yet (invalid for another 12h 46min 9s). Updates for this repository will not be applied.
```
By doing on remote system (example):
```sh
sudo systemctl stop ntp.service
sudo ntpd -gq
sudo systemctl start ntp.service
```
### zoneminder
- Enable authentification in (Option->System)
- Create new Camera:
  - General>Name: BirdCam
  - General>Function: Ffmpeg
  - General>Function: Modect
  - Source>Source Path: `rtsp://user:pw@ip:554/cam/mpeg4`
- Change default admin password
- Create users



## RaspberryPi
- Install raspbian lite (2022-09-22-raspios-bullseye-arm64-lite.img) on pi
- Get IP of remote system (192.168.20.11)
- Create ssh-config entry
```config
Host pi
     HostName 192.168.20.11
     Port 22
     User tudattr
     IdentityFile /mnt/veracrypt1/genesis
```
- enable ssh on pi
- copy public key to pi
- change user password of user on pi
- execute `ansible-playbook -i production --ask-vault-pass --extra-vars '@secrets.yml' pi.yml`

## Mikrotik
- Create rsa-key on your device and name it mikrotik_rsa
- On mikrotik run: `/user/ssh-keys/import public-key-file=mikrotik_rsa.pub user=tudattr`
- Create ssh-config entry:
```config
Host mikrotik
     HostName 192.168.70.1
     Port 2200
     User tudattr
     IdentityFile /mnt/veracrypt1/mikrotik_rsa
```

## Todo
- Role to setup backup
- Role to load customization/configurations from backup to servers
- aya01 fstab
