chamber VS direnv

Chamber takes an opinionated view on AWS Parameter store as compared to ssmsh

Building on this I’ve found https://github.com/segmentio/chamber to be super useful

For secrets, the PaaS platform (Github Actions, Fly.io, etc.) I usually use has a method that works with environment variables. If I need something custom on AWS, then I use Chamber backed by AWS KMS.

We use Chamber (https://github.com/segmentio/chamber) to do this for us. Bring it into your image and use the environment variables as necessary. Some applications support using environment variables natively, you might need to add a script to write them into your config files.

You can take a look at some code I wrote a while back to do this if you want examples https://github.com/segmentio/chamber/blob/master/store/ssmstore.go .

We use AWS Parameter Store and segmentio/chamber.

https://github.com/segmentio/chamber is nice with parameter store, ive used it in the past.

Use Chamber.

For interacting with SSM, I would recommend using https://github.com/segmentio/chamber. You could add something to your user-data script that uses chamber to load a config file (chamber export is one way to do it) from SSM on startup. You could also use Systems Manager to enable you to do a "hot reload" of sorts by sending a command to your server to run the chamber command and restart your application.

I think direnv already does a good job in this space, and it's already available in your package manager.

I switched from asdf to mise after a comment on lobste.rs[1] suggested I do so a few months ago, and I have been very happy with it.

It sands off some of asdf's sharp UI edges and provides a somewhat larger but still reasonable feature set; I've also replaced most of my direnv[2] usage with it.

The mise -> asdf comparison page is useful[3]

I also made the export diff configurable, motivated by this post: https://github.com/direnv/direnv/pull/1233

Nice.

For years I've been using [direnv](https://direnv.net/) for this, setting environment variables which git picks up. This looks like a more feature complete equivalent, although to be honest I only really need switching of committer email and the SSH key used.

Direnv, for the uninitiated, loads and unloads environment variables when directories are entered and exited. Under every project folder there is a `$PROJ_DIR/.envrc` which contains:

buffer-env: A pure-Elisp version of the direnv utility. Useful to make Emacs aware of Python virtualenvs (which, judging by the questions posted here, is unfortunately still a complication for a lot of people). Similar to (and inspired by) envrc, but doesn't require the direnv program.

You can look at direnv to see this in action as they wrote shell hooks that get loaded into the shell profile and are executed on every prompt. https://direnv.net/

Yes, most Nix users employ https://direnv.net or the equivalent for your IDE of choice. Emacs for instance has https://github.com/purcell/envrc which set per-buffer variables.
