 # TuDatTr IaC
 
-## User
+**I do not recommend this project being used for ones own infrastructure, as
-It is expected that a user with sudo privilages is on the target, for me the users name is "tudattr"
+this project is heavily attuned to my specific host/network setup**
-you can add such user with the following command `useradd -m -g sudo -s /bin/bash tudattr`
+The Ansible Project to provision fresh Debian VMs for my Proxmox instances.
-Don't forget to set a password for the new user with `passwd tudattr`
+Some values are hard coded such as the public key both in
-## sudo
+[./scripts/debian_seed.sh](./scripts/debian_seed.sh) and [./group_vars/all/vars.yml](./group_vars/all/vars.yml).
-Install sudo on the target machine, with debian its
+
+## Prerequisites
+
+- [secrets.yml](secrets.yml) in the root directory of this repository.
+  Skeleton file can be found as [./secrets.yml.skeleton](./secrets.yml.skeleton).
+- IP Configuration of hosts like in [./host_vars/\*](./host_vars/*)
+- Setup [~/.ssh/config](~/.ssh/config) for the respective hosts used.
+- Install `passlib` for your operating system. Needed to hash passwords ad-hoc.
+
+## Improvable Variables
+
+- `group_vars/k3s/vars.yml`:
+  - `k3s.server.ips`: Take list of IPs from host_vars `k3s_server*.yml`.
+  - `k3s_db_connection_string`: Embed this variable in the `k3s.db.`-directory.
+    Currently causes loop.
+
+## Run Playbook
+
+To run a first playbook and test the setup the following command can be executed.
 
 ```sh
-su root
+ansible-playbook -i production -J k3s-servers.yml
-apt install sudo
-usermod -a -G sudo tudattr
 ```
 
-## Backups
+This will run the [./k3s-servers.yml](./k3s-servers.yml) playbook and execute
-Backup for aya01 and raspberry are in a backblaze b2, which gets encrypted on the clientside by rclone.
+its roles.
-but first of all we need to create the buckets and provide ansible with the needed information.
-
-First we need to create a api key for backblaze, consists of an id and a key.
-we use clone to sync to backblaze.
-we can encrypt the data with rclone before sending it to backblaze.
-to do this we need two buckets:
-- b2
-- crypt
-on each device that should be backupped.
-
-we create these by running `rclone config` and creating one [remote] b2 config and a [secret] crypt config. The crypt config should have two passwords that we store in our secrets file.

-## Vault
-- Create vault with: `ansible-vault create secrets.yml`
-- Create entry in vault with: `ansible-vault edit secrets.yml`
-- Add following entries: TODO
-  
-## 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:
-  host: "service"
-  ports:
-    http: "19999"
-  volumes:
-    config: "{{ docker_dir }}/service/" # config folder or your dir
-    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: '775'
-    state: directory
-  loop:
-    - "{{ service.volumes.config }}"
-    - "{{ service.volumes.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"

-- 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
