minikube is a specific version/distro/packaging of kubernetes meant for testing on local laptop. Docker Swarm runs exactly the same way with exactly the same components and with the same ease on laptop as well as the cloud. TL;DR - you cant run minikube in production.

  It's just Kubernetes in a VM, like Docker on Mac is just docker in a VM. You can run Kubernetes on your Linux device machine as-is.

    It's what's in the VM that counts.

  Creating a k8s cluster on GKE is just as easy (a single gcloud command, or use the GUI if that is your preference). With hosted Kubernetes as a service (GKE, AKS and soon EKS), there is little reason to roll your own cluster.
  - Axsuul 9y ago
    But you see with Docker Swarm, you don't need "Docker Swarm as a service". That's why Docker Swarm wins in simplicity.

  I see your point. For k8s production, you'd have to use a solution provided by the cloud operator, GoogleKE / AzureKS / AmazonKS / etc. Which leaves the on-prem cluster and/or baremetal hosted cluster uncovered. Not that I'm convinced it's worth running baremetal anything, you're likely to be less efficient than large cloud operators because of economies of scale. Nit: $ minikube get-k8s-versions The following Kubernetes versions are available when using the localkube bootstrapper: - v1.9.4 - v1.9.0 - v1.8.0 - v1.7.5 - v1.7.4 - v1.7.3 - v1.7.2 - v1.7.0 - v1.7.0-rc.1 - v1.7.0-alpha.2 - v1.6.4 - v1.6.3 - v1.6.0 - v1.6.0-rc.1 - v1.6.0-beta.4 - v1.6.0-beta.3 - v1.6.0-beta.2 - v1.6.0-alpha.1 - v1.6.0-alpha.0 - v1.5.3 - v1.5.2 - v1.5.1 - v1.4.5 - v1.4.3 - v1.4.2 - v1.4.1 - v1.4.0 - v1.3.7 - v1.3.6 - v1.3.5 - v1.3.4 - v1.3.3 - v1.3.0

    I used this for baremetal: https://github.com/kubernetes-incubator/kubespray https://github.com/kubernetes-incubator/kubespray

  I used kubespray to set up a Kubernetes cluster on our own hardware. I have Ansible and Docker knowledge and ran into a few issues, but it didn't take much time to set up a custom cluster. It's still different as I had issues accessing the UI, but I think it'll become even more easier in the next month.

What about HA / clustering, security mTLS?
- pacala 9y ago
  Why would you want any of those on your laptop?
  - dahidahi1 9y ago
    Because that is how I will deploy on production. At least the security pieces. Any difference & I am not sure if I can be assured of preventing the "works on my machine" kind of issues.
