My current company uses it and that is not a bad choice. I prefer nomad which I have used since 2016.

I have spent the past couple weeks working with kustomize since I do not like helm and while it gets the job done I think Tanka would be better.

We are on GKE which makes things a lot easier and I personally would not choose to run my own cluster.

(disclaimer: i worked at hashi for 4 months in 2020 but not related to nomad)
