- Is docker the best tool to learn starting out?
- Which orchestration tools should I learn, beyond docker and docker-compose for deploying the containers? Furthermore, which should I avoid?
- What is the ideal distribution for running your containers? Currently I have an RPi running Hyriot and an Ubuntu 20.04 VM on a VMWare host. Considering Debian rather than Ubuntu but looking for other recommendations as well.
- Is a dockerswarm or kubernetes cluster necessary if I only have a single VM host to run my containers on? I plan on building out one or both to learn the ins and outs but for containers I want to rely on, would it be best to run it on a single stable VM or across the swarm/cluster if all on single underlying hardware?
I know I'll have more but wanted to get feedback from the group as I know this has probably been a topic of discussion many times over the last few years.
Lastly for the next meetup, would someone be willing to discuss the ramification of Kubernetes dropping docker support in the future? What will be supporting in its place? I've drug my feet on this and now trying to get up to speed so any input is appreciated.
I have no experience with swarm or compose, but I have used Docker for a while, and I can say that Kubernetes helps me even on a single node cluster.
The ecosystem built around it has automated and abstracted out a lot of things I used to have to piece together and manually do myself. Automating the SSL cert process, DNS updating with DDoS protection & CDN providers like Cloudflare, creating storage replicated across the cluster where possible, setting up databases and web apps in one step that used to each have their own way to install, and it was a pain to get more than one of them running on the same server, etc.
It may be a lot of overhead for a getting started test / dev environment, and has a bit of a learning curve, but that learning of how to deploy an app on even a single node can pretty seamlessly scale and translate to a production environment with many nodes.
I'm partial to Debian and its descendants, but I hear good things about CoreOS / Container Linux / now Fedora CoreOS? (Maybe getting that wrong) I've just used Debian for many years and I'm familiar with how to tinker with it when things go wrong
As I understand it, the upcoming removal of Docker from Kubernetes does not mean that it won't still run containers built with Docker. Docker will still be useful for developing apps that run on Kubernetes. I could be wrong.
