|
**I do not recommend this project being used for ones own infrastructure, as
|
|
this project is heavily attuned to my specific host/network setup**
|
|
The Ansible Project to provision fresh Debian VMs for my Proxmox instances.
|
|
Some values are hard coded such as the public key both in
|
|
[./scripts/debian_seed.sh](./scripts/debian_seed.sh) and [./group_vars/all/vars.yml](./group_vars/all/vars.yml).
|
|
|
|
## 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
|
|
ansible-playbook -i production -J k3s-servers.yml
|
|
```
|
|
|
|
This will run the [./k3s-servers.yml](./k3s-servers.yml) playbook and execute
|
|
its roles.
|
|
|
|
## After successful k3s installation
|
|
|
|
To access our Kubernetes cluster from our host machine to work on it via
|
|
flux and such we need to manually copy a k3s config from one of our server nodes to our host machine.
|
|
Then we need to install `kubectl` on our host machine and optionally `kubectx` if we're already
|
|
managing other Kubernetes instances.
|
|
Then we replace the localhost address inside of the config with the IP of our load balancer.
|
|
Finally we'll need to set the KUBECONFIG variable.
|
|
|
|
```sh
|
|
mkdir ~/.kube/
|
|
scp k3s-server00:/etc/rancher/k3s/k3s.yaml ~/.kube/config
|
|
chown $USER ~/.kube/config
|
|
sed -i "s/127.0.0.1/192.168.20.22/" ~/.kube/config
|
|
export KUBECONFIG=~/.kube/config
|
|
```
|
|
|
|
Install flux and continue in the flux repository.
