Hi, I am currently working on an initial setup of Kubernetes at my job. And I keep running into some issues 1. I have 8 nodes of Amazon Ec2 and some have ubuntu and some have Linux so I keep running in installation problems. is it common to have different OS/flavors of linux across nodes? 2. Which do I use, CRI or containerd? Keep in mind that all nodes have Docker containers running in them, and I don't want to disrupt them. 3. For network configuration, Calico is recommended, but I'm running into problems with it and cant join the nodes. Any advice will be highly appreciated, and if you can point out a good tutorial, that will be great!

Initial question would be, are you not able to use AWS EKS? Managed offerings simplify a lot of these kinds of issues if you are able to use them (also FYI there is a #C037GR3TNH5 channel)

Thanks for your reply. I figured the networking issue was due to wrong address config in API and etcd manifest files and also had to fine-tune the inbound rules on AWS. Instead os calico I am using weave. Why not EKS? Plan is to build a in-house monitoring tool integrated with our TIG stack(or promtheous in the future). Will check out the channel 🙂 Thanks Again
