Personal experience:
Argo workflows and Argocd (vs. something like Harness) - Requires a handful of customizations to get it parity, but it’s really useful out-of-the-box I think. Good ol’ Jenkins works too, I suppose.
Soon, OpenTofu - unfortunately Hashicorp is going IPO which means bad news. OpenTofu is the fork of terraform.
Podman - Docker alternative. It’s really close, especially with Podman Desktop. I had a few issues that I ran into, but there are probably workarounds.
Vscode / codium - yeah it’s Microsoft, and has tracking. But it’s popular for a reason.
Does…that make all those things okay then?
