We use localstack for as much of our integration tests as we can, and have multiple paid licenses. When we started using it I was skeptical that it could reliably mimic all the AWS services we use, and I was right. Don’t get me wrong it’s a valiant effort and it lets us run tests much faster (and obviously cheaper) than the real thing, but those same tests need to pass on live AWS too before we have any confidence in our code.
If any of the localstack authors are reading this, thank you for your tireless efforts!
exactly - it is meant to approximately work as a localized AWS environment for use during development, and for writing "unit" tests, and basic integration tests.
A full on, end-to-end testing is still required, but with localstack, you can run those once after you've completed development.
I have used LocalStack for all sorts of tinkering and local development without the fear of credit bomb on a “trial” AWS account. Highly recommended and very easy to get started with. So excited to see this growing and hitting v1.0.
Is it only me, but I'm annoyed that they don't start with "LocalStack is ABC". Do they assume only people who know what LocalStack is arrive at the page? (I agree the name is somewhat a good one though)
Last time I tried to use this, it wouldn’t pass dependency vulnerability scanning to bring it into the company. Obviously it’s not going into production, but it doesn’t seem a big ask to eliminate known CVEs.
Thanks for the feedback! LocalStack CTO here. Very timely - we're right now in the process of upgrading all dependencies (JAR files, etc) in our Docker images to reduce the exposure for potential vulnerabilities.
The scan results of the security scanning tool we're using look promising - they're almost green already.. :) Please let us know if there's anything particular that's blocking you from bringing it into your company! Appreciated
While I admire their effort to do all the clouds, I would expect the actual code overlap between emulating the AWS APIs and Azure APIs would be infinitesimal and would likely benefit from a separate localstack-azure project
Or, actually, put another way: since localstack stood on the shoulders of the absolutely incredible moto library, I would find out if there is an equivalent for Azure and start there
Azurite is good for azure storage service emulation and they respond to issues with lightning speed. Aside from storage I’m not aware of anything
Quick edit: there is a cosmosdb emulator out there for windows. Last I looked (6 months ago?) there was not a Linux version (so no docker). If you’re in windows with wsl though not bad. Azure function core tools is also excellent for local dev.
I don't see how grocery store prices are related with people dying of hunger. That's going from one end of the problem to the other and doesn't help anyone when you ignore all the issues in between.
