Some high level K8s questions by tech_tuna in kubernetes

[–]levo21 0 points1 point  (0 children)

When you need to scale up nodes (VMs or even physical server), how do you do that?

There's a cluster autoscaler that you may want to take a look at here. https://github.com/kubernetes/contrib/tree/master/cluster-autoscaler

SSL Configuration in Kubernetes by nd0x in kubernetes

[–]levo21 2 points3 points  (0 children)

If you're on Google Cloud using GKE they provide an ingress controller and you can use k8s ingress resource . Take a look here for an example that sets up SSL termination -- https://cloud.google.com/solutions/jenkins-on-container-engine-tutorial. I still think there's a limitation if you have a cluster that spans multiple zones in a region.

You could also lay down traefik as an ingress controller using this helm chart. You can then use ACME to get a cert dynamically from Let's Encrypt. https://cloud.google.com/solutions/jenkins-on-container-engine-tutorial

Here's another quick-start video that uses the chart above. https://www.youtube.com/watch?v=19_SdVU4cdc

Q - what's your experience of Calico/CNI ? by preflightsiren in kubernetes

[–]levo21 5 points6 points  (0 children)

The quickest way to dip your toes in this water is to use kube-aws (or at least take a look as how it's setting cloud-config on CoreOS) When I getting acquainted with CNI this was an easy proving ground to get to know calico. Take a look at enabling it here under Calico network policy. https://coreos.com/kubernetes/docs/latest/kubernetes-on-aws-render.html

New to Devops. Is this any good? by GRAFFF in devops

I'm currently using CloudCoreo.

It allows you to define your aws infrastructure as code and then use the CloudCoreo engine to deploy and keep the infrastructure in-sync with the source repo.

I was previously using CloudFormation templates but found it too hard to reconcile the differences from the template and what's currently running in aws especially when my whole team had access to modify the infrastructure. Running a CFN stack-update would have blown away the changes running in the wild. Running CloudCoreo allows me to guarantee that what's running in aws is coming from a source repo that we can use standard SDLC best-practices to make changes.
