More like 2 I guess? Tbh running apps on Kubernetes is quite simple provided you have a pre-existing cluster. Running Kubernetes itself is definitely not simple and unless you already have a team skilled at running such things I would always opt for one of managed clusters from the big cloud providers.
- raghule 4y agoI'd love to learn more about how you first built an app for K8s. Like did you have an existing app you were porting to K8s or what was the app dev cycle looked like?
- WJW 4y agoThe first app I ever ported to k8s was an existing ruby app that worked as an URL shortener. I could already run it locally. The platform team had put up a cluster in the staging environment to test on and a private docker image repo on AWS. The steps to get it onto the cluster were roughly: 1. Write a dockerfile for the service and test if I can run the service locally in docker. 2. Push the dockerfile to AWS. 3. Cobble together Deployment, Service and Ingress yaml files from reading tutorials and docs, then apply those to the cluster and observe what happens. Repeat until it works. 4. We slowly iterated our tooling and yamls as we learned more.
