Kubernetes Webinar - Questions Answered

We had a great turnout for our Kubernetes Webinar! This was a culmination of a six part series that I wrote on the Harness Blog.


We had some great questions asked but we ran out of time. Here are the questions that were asked but were not answered on the webinar.

  1. How does Kubernetes compare with Redhat open shift? Ravi Lachhman: Red Hat OpenShift is a Platform-as-a-Service (PaaS) offering by Red Hat which gives a prescription on application infrastructure such as JBoss, etc. Kubernetes is a container orchestrator. Red Hat OpenShift since version 3.0 uses Kubernetes as the orchestration engine inside the platform.
  2. How well does Harness work with Rancher? How does Harness compare with Azure DevOps tools? Ravi Lachhman: We are pretty agnostic with tool stack as we are more of an orchestrator for disperate pipeline processes so nothing would prevent the use of Rancher. Azure DevOps is a highly prescriptive stack from Microsoft. If leveraging Azure, Azure DevOps is a culmination of several tools. Harness can still help orchestrate disparate processes and be agnostic / split cloud vendors in a pipeline.
  3. Where is the kubernetes blog series? Ravi Lachhman: Part one through six are in our “how-to” section. https://harness.io/category/how-to/. Part six is at https://harness.io/2019/08/kubernetes-series-part-6-6-the-future-modify-the-kubernetes/.
  4. I din’t get completely Harness role - how it relates to helm or istio? Ravi Lachhman:
    Helm is a configuration/package manager for Kubernetes itself. You can template Kubernetes configurations and deployments for example with Helm. There are other options than helm which we go through in the blog series. Istio is a service mesh technology. Harness can help supercharge your Istio based deployments. https://harness.io/2018/08/harness-istio-support-for-blue-green-and-yellow-canary-deployments/
  5. How is Harness different from likes of Puppet? We are a Splunk and AppD house, how can Harness add value? Ravi Lachhman: Puppet is configuration as code. Puppet, Splunk, and AppD are all important parts of your DevOps/Pipeline tool chain and Harness is not here to replace. We can supercharge your experience with those tools orchestrating sophisticated pipelines taking into decisions that those tools have or make.
  6. How common are .net apps on docker/kubernetes? How do people normally use databases alongside Kubernetes? Ravi Lachhman: There has been a lot of advancement in Docker on Windows. There is still a split on images that are created on Windows vs those on Linux. You can split workloads with tags so Windows workloads go to Windows nodes and Linux work nodes do the same. For the database question, depends if the database can be containerized and clustered easy if needing redundancy. CockroachDB is a good example of a Kubernetes friendly Postgres compliant DB.

Honored to help educate folks on K8s. Check out the recording of the webinar if you have not seen yet.
