#kubernetes (2021-08)

Hi folks! I’ve got a kubernetes cluster running on an old machine which I’m using for a home server. Kubernetes is undoubtedly an overkill for my purposes, but I’m in this for the learning. My problem is the following: I currently have a docker-compose file with a series of containers I use. One of them is a VPN container that I use to put in front of other containers (from a network perspective). When I want a container to be behind this containerized VPN I’ve created, I just add the following network_mode: service:vpn to the docker-compose file. At the moment, I’m trying to migrate these pure docker containers to my kubernetes cluster but I currently got no clue on how to do a similar thing with this VPN situation. Any ideas?

Couldn’t find any discussion on this in archives. Anyone using this here and have a quick set of pointers for a complete k8 n00b like myself? About to play around with provisioning some applications using k8’s other manage and setting up DAPR & k8s locally with Lens too. Any other essentials or quick 101 articles would be welcome if you found something invaluable. I know that’s a broad thread topic, but as I’ve not used k8s before, I’m sure your experience might point me to a few resources that are not obvious to me

Hello, what’s your strategy to size Kubernetes node_pool ?

• do you use a node_pool for system and multiple node_pool ?

• how much pod do you set per node ? ◦ for the default node pool ◦ for other node_pool ◦ maximum looks to be 110, is this a recommendation or a hard limit ? https://kubernetes.io/docs/setup/best-practices/cluster-large/ In AKS there is an option to taint default node pool for system only, I guess it’s mendatory for production to have it enabled https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/kubernetes_cluster#only_critical_addons_enabled
