| Thanks. I'm excited to become a pod person.

| Docker is really easy. A few lines to describe your environment
| and a handful of commands (docker build, run, ps, images) and
| you are up and running.
|
| Orchestration is more complex, but not too bad if you are using
| a managed platform.
|
| A few days and you can get your head around it enough to get
| started with huge payback in efficiency.
|
| After that, you can spend years really going deep on K8s and
| fully containerised stacks, but that's more for DevOps/Cloud
| engineers rather than Devs.

| _Running_ a Kubernetes cluster, in a shared environment (e.g.

| it is a deep subject with lots of unintuitive and frustrating
| corners, and you won't pick it up in a day or without scars.
| There's a reason lots of small- and medium-sized business just
| write a check to their cloud provider.

| I'd say so. I've been using k8s as a basis for all my projects

| home that runs dozens of services flawlessly. Flux is the
| easiest devops deployment system I've ever had.
|
| For work, having minikube + skaffold is perfect for local dev
| of complex apps. And it's easy to use production deployment
| manifests with it. It's also easy to use Kind for running
| integration and e2e tests. The ecosystem is second to none.

| If you're curious about orchestration concepts in general,

| than the whirlpool of obscenity that is k8s.

| I fully support this! Nomad has a much smaller API surface

| is also much more straight forward.
| abalashov wrote:
| +1, Nomad is fantastically simple (but still flexible), and
| gives you the proper level of insight into the nature of
| orchestration and distributed container workloads without
| bogging you down with arbitrary figments of "because
| Kubernetes" complexity.
|
| After spending a day with Nomad, I feel I fully understand
| how this could get nightmarishly complicated in a Kubernetes
| way, and what that would look like, and why someone would
| want that in some situations. All the understanding without
| pointless but exacting detours.
