cluster-template VS sops

k8s is a lot easier for homelabs than it used to be, and imo it's quicker than nix for building a declarative homelab. templates like this one can deploy a cluster in a few hours: https://github.com/onedr0p/cluster-template

here's my home assistant deployment as a single file: https://github.com/pl4nty/homelab/blob/main/kubernetes/clust...

I deliberately nuked my onprem cluster a few weeks ago, and was fully restored within 2 hours (including host OS reinstalls). and most of that was waiting for backup restores over my slow internet connection

example repo: https://github.com/onedr0p/flux-cluster-template

Magical setups like this often get a lot of bad rap, but if you already understand Ansible and know Linux etc, you might find this repo a good start to building out your own cluster using gitops: https://github.com/onedr0p/flux-cluster-template

more of an end-to-end solution than a build-it-yourself, but this was a huge help in my understanding of k8s and the other tech like gitops - https://github.com/onedr0p/flux-cluster-template

idk how it'd scale for a larger operation, but flux+sops+age has worked great for me. based on https://github.com/onedr0p/flux-cluster-template

Here is a really good and VERY thorough example of pulling that all together: https://github.com/onedr0p/flux-cluster-template

My script just sets up default .sops.yaml for https://github.com/getsops/sops

You can further edit .sops.yaml(eg have multiple of them) and decide how you split secrets in your directory tree to further customize who can decrypt the secrets.

It works pretty well for prod/dev splits, etc

Mozilla SOPS (Secrets OPerationS) is an open-source command-line tool for managing and storing secrets. It uses secure encryption methods to encrypt secrets at rest and decrypt them at runtime. SOPS supports a variety of key management systems, including AWS KMS, GCP KMS, Azure Key Vault, and PGP. It's particularly useful in a DevOps context where sensitive data like API keys, passwords, or certificates need to be securely managed and seamlessly integrated into application workflows.

Encrypted secrets thanks to SOPS and Age

We do the exact same thing to keep track of some credentials we use sops[1] and AWS KMS to separate credentials by sensitivity, then use the git differ to view the diffs between the encrypted secrets

Definitely not best practice security-wise, but it works well

For anyone new to SOPS like I was - https://github.com/getsops/sops

I've found this is largely solved by strictly separating plain config and secrets, and then having secrets pull from GCP secret manager / vault / whatever.

You can then commit all the config (including the secret identifiers) and it all just works so long as you're authenticated with your secret storage system.

We do this for the live configuration as well in line with Gitops and find it to work well.

If you don't want to use a cloud secret manager you can also use something like https://github.com/getsops/sops to commit the encrypted secrets safely

Basically, the simpler the better --just encrypt your secrets and check them in to version control.

We use SOPS[0] for this, and have found it to be pretty nice.

The answer is that secrets shouldn't be stored in the git repo at all, but somewhere safe like a password manager or Mozilla's SOPS which people seem to love.

Unfortunately, the SOPS project is in some sort of a limbo state and there has been quite a long period with limited maintenance and unclear position from Mozilla. Despite the project being accepted into the CNCF, it's still unclear what will happen with it going forward.
