# TuDatTr IaC ## User It is expected that a user with sudo privilages is on the target, for me the users name is "tudattr" you can add such user with the following command `useradd -m -g sudo -s /bin/bash tudattr` Don't forget to set a password for the new user with `passwd tudattr` ## sudo Install sudo on the target machine, with debian its ```sh su root apt install sudo usermod -a -G sudo tudattr ``` ## 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. When creating your own rclone config the `password` and `password2` entries have to be passed though `rclone obscure` like this: ``` sh echo "$PASSWORD" | rclone obscure - ``` ` ## 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: ` (password you've setup on the device) - `vault_aya01_tudattr_password: ` (password you've setup on the device) - `vault_pihole_password: ` (arbitrary password you want to log in with) - `vault_mysql_root_password: ` (arbitrary password, used internally) - `vault_mysql_user_password: ` (arbitrary password, used internally) - `vault_ddns_tudattrdev_password: ` (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: ` (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/)) ## Docker To add new docker containers to the docker role you need to add the following and replace `service` with the name of your service: - Add relevent vars to `group_vars/all/vars.yaml`: ```yaml service_port: "19999" # Exposed port service_config: "{{ docker_dir }}/service/" # config folder or your dir service_data: "{{ docker_data_dir }}/service/" # data folder or your dir (only works on aya01) ``` - Create necessary directories for service in the docker role `roles/docker/tasks/service.yaml` ```yaml - name: Create service dirs file: path: "{{ item }}" owner: 1000 group: 1000 mode: '777' state: directory loop: - "{{ service_config }}" - "{{ service_data }}" # optional: # - name: Place service config # template: # owner: 1000 # mode: '660' # src: "templates/hostname/service/service.yml" # dest: "{{ prm_config }}/service.yml" ``` - Includ new tasks to `roles/docker/tasks/hostname_compose.yaml`: ```yaml - include_tasks: service.yaml tags: - service ``` - Add new service to compose `roles/docker/templates/hostname/compose.yaml` ```yaml service: image: service/service container_name: service hostname: service networks: - net ports: - "{{service_port}}:19999" restart: unless-stopped volumes: - "{{service_config}}:/etc/service" - "{{service_lib}}:/var/lib/service" - "{{service_cache}}:/var/cache/service" ``` ### Qbittorrent/Openvpn You'll need to add a openvpn config to =./roles/docker/templates/aya01/qbittorrentvpn/config/= ## 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 ``` ### wireguard thanks to [mikrotik](https://www.medo64.com/2022/04/wireguard-on-mikrotik-routeros-7/)0 quick code ``` # add wiregurad interface interface/wireguard/add listen-port=51820 name=wg1 # get public key interface/wireguard/print $ > public-key: # add network/ip for wireguard interface ip/address/add address=192.168.200.1/24 network=192.168.200.0 interface=wg1 # add firewall rule for wireguard (maybe specify to be from pppoe-wan) /ip/firewall/filter/add chain=input protocol=udp dst-port=51820 action=accept # routing for wg1 clients and rest of the network > # enable internet for wg1 clients (may have to add to enable internet list /ip/firewall/nat/add chain=srcnat src-address=192.168.200.0/24 out-interface=pppoe-wan action=masquerade ``` add peer ``` /interface/wireguard/peers/add interface=wg1 allowed-address=/24 public-key=" peer_A.pub` Wireguard config on archlinux at `/etc/wireguard/wg0.conf`: ``` [Interface] PrivateKey = Address = 192.168.200.250/24 [Peer] PublicKey = Endpoint = tudattr.dev:51820 AllowedIPs = 0.0.0.0/0 ``` used ipv4: - tudattr: 192.168.200.250 - livei: 192.168.200.240 #### notes - wireguard->add name: wg_tunnel01 listen port: 51820 [save] - wireguard->peers->add interface: wg_tunnel01 endpoint port: 51820 allowed address: ::/0 psk: persistent keepalive: 25 - ip->address->address list->add address:192.168.200.1/24 network: 192.168.200.0 interface: wg_tunnel01 ## troubleshooting ### Docker networking problem `docker system prune -a` ### Time problems (NTP service: n/a) systemctl status systemd-timesyncd.service when not available sudo apt install systemd-timesyncd/stable ### Syncthing inotify echo "fs.inotify.max_user_watches=204800" | sudo tee -a /etc/sysctl.conf https://forum.cloudron.io/topic/7163/how-to-increase-inotify-limit-for-syncthing/2
