# 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`
|
|
## 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: <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/))
|
|
|
|
## 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
|
|
```
|
|
