Maybe I haven't worked at enough places, but... when has this ever been allowed/encouraged/normalized?

edit: it’s not covered in the post, but it is on the launch and doc site: https://secretspec.dev/providers/onepassword/

Realistically, why would your different environments have different ways of consuming secrets from different locations? Yes, you wouldn't use AWS Secrets Manager in your local testing, maybe... but giving each developer control and management of their own secrets, in their own locations, is just begging for trouble. How do you handle sharing of common secrets? How do you handle scenarios where some parts are shared (e.g. a shared api key for a dev third party API) but others aren't (local instance of test db)? How do you make sure that api key that everyone uses in dev is actually rotated from times to times, and nobody has stored it in clear text .env because once they had issues with OnePassword's service being down, and left it at that? How do you make sure that nobody is using an insecure secrets manager (e.g. LastPass)?

It's just adding the risk of having the impression that there is proper secrets management, but actually having a mess of everyone doing whatever they feel like with secrets, with no control over who has access to what, and what secret is used where and by whom and why. Which is kind of like a good ~70% of the point of secrets management.

Centralised secrets management or bust, IMO. Ideally with a secrets scanner checking your code doesn't have a secret in clear text left by mistake/lazyness. Vault/OpenBao isn't that complicated to set up, but if really is, your platform probably has something already.

Disclaimer: I work at HashiCorp, but opinions my own, I've been a part of the team implementing Vault at my past job for centralised secrets management and 100% believe it's the way things should be done to minimise the risk of mishandling secrets.

One key issue is that splitting general config from secrets is practically extremely difficult because once the variables are accessible to a running code base most languages and code bases don't actually have a way differentiate between them internally.

I skipped the hard part of trying to integrate transparently with actual encrypted secret stores. The architecture leaves open the ability to write a new backend, but I have found that for most things, even in production, the more important security boundaries (for my use cases) mean that putting plaintext secrets in a file on disk adds minuscule risk compared to the additional complexity of adding encryption and screwing something up in the implementation. The reason is that most of those secrets can be rotated quickly because there will be bigger things to worry about if they leak from a prod or even a dev system.

The challenge with a standard for something like this is that the devil is always in the details, and I sort of trust the code I wrote because I wrote it. Even then I assume I screwed something up, which is part of why I don't shared it around (the others are because there are still some missing features and architecture cleanup, and I don't want people depending on something I don't fully trust).

There is a reason I put a bunch of warnings at the top of the readme. Other people shouldn't trust it without extensive review.

Glad to see work in the space trying to solve the problem, because a good solution will need lots of community buy-in to build quality and trust.

It's a standalone tool with YAML configuration, simple to use.

Basically the way it works:

- You create the secret in GCP/AWS/etc Secrets Manager service, and put the secret data there.

- Refer to the secret by its name in Teller.

- Whenever you run `$ teller run ...` it fetches the data from the remote service, and makes it available to your process.

*Configuration Values*

Your laptop is not hosting your website (I presume), so .env is not going to be enough to run your app somewhere other than your laptop.

I get it. You only want to run your app locally, and .env is convenient. But your production server probably isn't going to load your .env file directly, and it will probably need extra or different variables. This disconnect between "the main development environment variables" and "the extra stuff in production" will lead to inconsistencies that you have not tested/developed against. That will lead to production bugs. So keeping track of those differences in a uniform way is pretty useful.

How do you specify configuration for development and production without running into inconsistency bugs? By splitting up your app's configuration into "static" and "dynamic", and version-controlling everything.

1) "Static" configuration is things like environment variables, which do not change from run to run, and are not environment-specific. So for example, an API URL prefix like "/api/routes" is pretty static and probably not going to change. But an IP address definitely will change at some point, so this configuration isn't static. (To think about it another way: on your computer, some environment variables are simply stored in a text file and read into your shell; these are static)

2) "Dynamic" configuration are values that may change, like hostnames, IP addresses, port numbers, usernames, passwords, etc. Secrets are also "dynamic", because they should never be hard-coded into a file or code, and you will want to rotate secrets in the future. All dynamic configuration should be loaded during a deployment process (for example, creating an ECS task definition, or Kubernetes yaml file), or at runtime (an ECS task definition that sources environments from secrets, or a Kubernetes yaml that sources environments from secrets, or a function in your code that calls an API to look up a secret from Hashicorp Vault or similar). In particular for secrets, you want to load those every time your program starts, as close to the application's execution environment as possible. (To think about it another way: some environment variables on your computer require executing a program and getting its output to set the variable - like your $HOSTNAME, $USER, $SHELL, and other variables)

3) Both static and dynamic configuration should be version-controlled, and any change to these should trigger a new deployment. If a value changes, and you don't then immediately make a new deployment, that change could be harboring a lurking bug that you won't find out about until someone makes a deployment much later on, and trying to find the cause will be very difficult.

*Infrastructure Patterns*

test, stage, and prod servers are like pets. You have individual relationships with them, change them in unique ways, until eventually they have their own individual personalities. They become silos that pick up peculiarities that will not be reflected in other environments, and will be hard to replicate or rebuild later.

Instead, use ephemeral infrastructure (the "cattle" in "pets vs cattle"). There should be a "production" infrastructure, which is built with Infrastructure-as-Code, to create an immutable artifact that can simply be deleted and re-created automatically. That same code that builds production should build any other server, for example for testing or staging. When the testing or staging is done, the ephemeral copy should be shut down. They should all be rebuilt frequently to prevent infrastructure rot from setting in.

This pattern does a lot of things, like making sure you have automation for disaster recovery, using automation to prevent inconsistencies, using automation to detect when your infrastructure-as-code has stopped working, saving money by turning off unneeded resources, and the ability to spin up a unique copy of your infrastructure with unique changes in order to test them in parallel to your other infrastructure/changes. It also makes it trivial to test upgrades, patch security holes, or destroy and recreate compromised infrastructure. And of course it saves you time in the long run, because you only expend effort to set it up once.

*This Is Not About Scaling*

I know the first thing everyone's going to complain about is something like "I'm not Facebook, I don't need all that!" or "It works fine for me!".

There's a lot of things we do today that are better for us than what we did before, even though we don't have to. You brush your teeth and wash your hands, right? Well we didn't used to do those things. And you can still live your life without doing them! So why do them at all?

Because we've learned about the downsides of not doing them, and the benefits outweigh the downsides. Getting into the habit of doing things differently may be annoying or painful at first, but then they will become second nature, and you won't even think about it.
