Re: How we use HashiCorp Nomad
#3I worked at a hedge fund that also used nomad. The problem, however, is not how well it scales or whatever, but the fact that all the accompanying deployment info and literature is for kubernetes, and k8s has far more features.
I like the quality of products from HashiCorp, but k8s is far, far, ahead of where nomad is.
What I really want is better integration for Terraform and kubernetes. The current TF k8s support leaves much to be desired, too many things are missing or broken and I find there are several bugs that result in deployment flapping (i.e., constantly re-deploying the same thing when there are no changes).

Which features is Nomad missing? Feature count comparisons are meaningless unless the features are tied to actual important use cases. Lots of software is encrusted with rarely used features that just add complexity.

#5Cloudflare, make sure you upgrade to 0.11.3, the new scheduling behavior is awesome for large clusters.
Also a massive warning to anyone wanting to use hard cpu limits and cgroups (they do work in nomad it’s just not trivial), they don’t work like anyone expects and need to be heavily tested.

The main missing feature is that it's not kubernetes.

For us it's not a feature missing, but the mindshare is low, and there's not really any prebuilt examples of how to run and maintain services long term reliably.

Does it have "easy" side-cars/init/post? Last time I checked those were missing for example.
Re: How we use HashiCorp Nomad
#9After trying out most of the kubernetes ecosystem in the pursuit of a declarative language to describe and provision services, Nomad was a breath of fresh air. It is so much easier to administer and the nomad job specs were exactly what I was looking for. I also noticed a lot of k8s apps encourage the use of Helm or even shell scripts to set up key pieces, which defeats the purpose if you are trying to be declarative about your deployment.

The free version of Nomad is missing, IIUC:
- no quotas for teams/projects/organizations
- no preemption (ie higher priority job preempts lower priority job)
- no namespacing
So generally it's somewhat useless in organizations where there are multiple different teams that should be able to coexist on a cluster without stepping on eachothers' toes, or even where you want a CI system to access the cluster in a safe manner.
