Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How are people managing env vars for Static Applications?
You can combine this approach with something like https://github.com/stakater/Reloader to automatically restart pods when a certain secret value changes. So if your static code needs to be rebuilt when certain values change, you can use an init container to run the build on startup.
-
Containers are crashing due to memory exhaustion caused by secret rotation every minute.
This is not a cron job? I'm not sure if it helps, but you can have pods do a rolling restart on secret updates: https://github.com/stakater/Reloader that would clear the resources each run, but I'm not entirely clear on what you're looking to achieve.

True Secrets Auto Rotation with ESO and Vault
If you use secrets as Environment Variables you will need to use something to make workloads get the new credentials, if they just loose connection. You can use the Reloader project for that.

Automating Configuration Updates in Kubernetes with Reloader
Reloader is designed to simplify the process of updating application configurations in Kubernetes. It monitors ConfigMaps and Secrets for changes and triggers rolling upgrades for associated resources such as Deployments, StatefulSets, DaemonSets, and more. Reloader eliminates the need for manual intervention and reduces the risk of errors during the configuration update process.

How to start a Go project in 2023
The go k8s packages are pretty bloated - this may also just be a niche case. If you are looking to get secrets with hot reloading, you might also consider mounting a file or setting env vars and coupling it with this reloading operator: https://github.com/stakater/Reloader

For the auto restart this has been a staple install in all clusters for years for me: https://github.com/stakater/Reloader

Flux & Helm noob here - How do I pass secret values to Helm charts being handled by Flux?
If you didn't want to use SOPS, for some reason, you can certainly take advantage of external secrets as another commenter proposed, but you won't be able to accomplish (2) without an external tool adding to the mix, like Reloader: https://github.com/stakater/Reloader β that's because something has to update the HelmRelease in order to trigger it to upgrade. (You could just wait for the reconciler to come along, but the tendency is to set the polling interval longer than the default, so Helm won't be re-trying as often, in case something goes wrong...)

Environment variables - manifest or configMap?
You can install https://github.com/stakater/Reloader And then it's just matter of a single annotation and it restarts automatically when there are changes.

Testcontainers
I am using https://github.com/ory/dockertest for tests, specifically for databases. Is there any advantage to use Testcontainers?

Level UP your RDBMS Productivity in GO
Now, let's run the tests. For this purpose, we are going to use dockertest, but test containers is also a good solution.

Golang testing using docker services via dockertest
During my path learning go so far I have come across some amazing libraries and utilites, one of my favourite for integration testing is dockertest.

How to start a Go project in 2023
Things I can't live without in a new Go project in no particular order:
- https://github.com/golangci/golangci-lint - meta-linter
- https://goreleaser.com - automate release workflows
- https://magefile.org - build tool that can version your tools
- https://github.com/ory/dockertest/v3 - run containers for e2e testing
- https://github.com/ecordell/optgen - generate functional options
- https://golang.org/x/tools/cmd/stringer - generate String()
- https://mvdan.cc/gofumpt - stricter gofmt
- https://github.com/stretchr/testify - test assertion library
- https://github.com/rs/zerolog - logging
- https://github.com/spf13/cobra - CLI framework
FWIW, I just lifted all the tools we use for https://github.com/authzed/spicedb
We've also written some custom linters that might be useful for other folks: https://github.com/authzed/spicedb/tree/main/tools/analyzers

How to unit test your database interactions with Docker
Reminds me of https://github.com/ory/dockertest
-
When to mock and what to mock in a Web API?
If your project is relatively simple and you can get away with recreating your scenarios against a real mock database and run other related services locally. It would be good to setup docker containers for your test scripts and write e2e tests. I believe e2e tests are harder but more useful in understanding/reasoning how users are impacted.
-
Don't Mock the Database
Just a heads up, the repository in your comment is invalid, the correct link is https://github.com/ory/dockertest
-
Mocking database calls without a library?
Don't mock. Use https://github.com/ory/dockertest to actually run tests against a dockerized DB.

Different SQL drivers for test and production
Use a library like ory/dockertest to spin up a test database for integration tests. It's easy to use, and tests are still fast. It'll take a minute to download the mysql docker image the first time. But, once it's been downloaded, starting the db, running migrations, and running the tests is still pretty quick.
