[Pulumi kube co-lead here] I agree with most of this, but would go further. My experience (here and at Heptio) is that no one _chooses_ Kubernetes. They choose Docker, and then they (i.e., the infra team) effectively have to choose ECS or Kubernetes. In contrast, what most app developers want is a better `docker run`. I don't know how controversial that is, so I should say this is my conclusion from ~50 intensive customer qualification conversations in my 1.5 years at Pulumi and 1 year at Heptio. In each of these conversations I ask why the customer is moving to Kubernetes. In mid- or large-sized companies (i.e., 500+ employees) the answer is completely unwavering: Docker makes it easy to ship software without worrying too much about the host, and once you have that, having a way to schedule containers to run _somewhere_ is very useful. And that's effectively how the decision is made IME.

I am very much hunting for a cli, automatable method to do: - app installs - orchestration of same across multiple boxes in a cluster - cluster monitoring: detect when a task or box goes down running the service(s) elsewhere in the cluster It seems like kubernetes is incomplete with respect to these needs. Kubernetes depends on docker but neither does orchestration. In the context of this HN post what do I need. I am doing golang on 100pct Linux. Other than toolng I need for app installs the boxes themselves are provisioned by others. Here I am focused on app installs only. Any help much, much appreciated.

  Take a look at Kubernetes, Helm, and the Cluster API.

    Can’t tell if grandparent post wants to manage apps on a cluster (see below) or apps that are a cluster (see https://cluster-api.sigs.k8s.io/ https://cluster-api.sigs.k8s.io/) If it’s letting a dev manage apps on a cluster someone else let them put apps on, while staying in dev mode, maybe devs could appreciate the cluster provisioning SREs enabling app devs with so-called GitOps or AutoDevOps approaches, prescriptivist ways of leveraging Docker, K8s, and Helm, such as: https://www.weave.works/blog/what-is-gitops-really https://www.weave.works/blog/what-is-gitops-really https://docs.gitlab.com/ee/topics/autodevops/index.html https://docs.gitlab.com/ee/topics/autodevops/index.html

  Kubernetes is pretty feature complete, but its focus is on containers, not naked apps. If you are willing to pack your apps into docker, kubernetes will solve the orchestration and monitoring problems. If you are not, you might want to look for something else. In particular, take a look at Nomad (https://www.nomadproject.io/ https://www.nomadproject.io/). I am not affiliated with the project in any way and at my workplace we went the kube route, but Nomad does provide an ability to orchestrate arbitrary processes across multiple hosts.
