flagger VS sops

Flagger

Where appropriate, canary releases are an excellent option, as the percentage of traffic exposed to the canary is highly controlled. The trade-off is that the system must have good monitoring in place to be able to quickly identify an issue and roll back if necessary (which can be automated). This guide shows you how to use Apache APISIX and Flagger to quickly implement a canary release solution.

What is Flagger? Flagger is a Progressive Delivery tool that automates the release process for applications running on Kubernetes. Under the hood, both tools are built on top of a modular GitOps toolkit. It is the main reason why Flagger compliments Flux.

I would suggest trying a-b deployment in this case using flagger. It will spin up a new instance and gradually rotate out old ones. Maybe that can be helpful in this weird situation :)

ArgoRollouts offers Canary and BlueGreen deployment strategies for Kubernetes Pods. It's a drop-in replacement for the v1.Deployment object. Flagger is similar what it offers, extending Kubernetes to support Canary and BlueGreen deployment strategies.

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

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.
