Oh Shit, Git!?! https://ohshitgit.com/
Mon 18 Jan 2021 01:53:50 PM CET wallabag

Git is hard: screwing up is easy, and figuring out how to fix your mistakes is fucking impossible. Git documentation has this chicken and egg problem where you can't search for how to get yourself out of a mess, unless you already know the name of the thing you need to know about in order to fix your problem.

So here are some bad situations I've gotten myself into, and how I eventually got myself out of them in plain english.

This tutorial presents Ansible step-by-step. You'll need to have a (virtual or physical) machine to act as an Ansible node. A Vagrant environment is provided for going through this tutorial.

Ansible is a configuration management software that lets you control and configure nodes from another machine. What makes it different from other management software is that Ansible uses (potentially existing) SSH infrastructure, while others (Chef, Puppet, ...) need a specific PKI infrastructure to be set up.

Ansible also emphasizes push mode, where configuration is pushed from a master machine (a master machine is only a machine where you can SSH to nodes from) to nodes, while most other CM typically do it the other way around (nodes pull their config at times from a master machine).

This mode is really interesting since you do not need to have a 'publicly' accessible 'master' to be able to configure remote nodes: it's the nodes that need to be accessible (we'll see later that 'hidden' nodes can pull their configuration too!), and most of the time they are.

This tutorial has been tested with Ansible 2.7.1.

upgrading: upgrading kubeadm clusters https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/

Upgrading kubeadm clusters

This page explains how to upgrade a Kubernetes cluster created with kubeadm from version 1.18.x to version 1.19.x, and from version 1.19.x to 1.19.y (where y > x).

To see information about upgrading clusters created using older versions of kubeadm, please refer to following pages instead:

Limit access to the nginx service 

To limit the access to the nginx service so that only Pods with the label access: true can query it, create a NetworkPolicy object as follows:

If you want to control traffic flow at the IP address or port level (OSI layer 3 or 4), then you might consider using Kubernetes NetworkPolicies for particular applications in your cluster. NetworkPolicies are an application-centric construct which allow you to specify how a pod is allowed to communicate with various network "entities" (we use the word "entity" here to avoid overloading the more common terms such as "endpoints" and "services", which have specific Kubernetes connotations) over the network

pvc: claims as volumes https://kubernetes.io/docs/concepts/storage/persistent-volumes/#claims-as-volumes
Fri 08 Nov 2019 10:25:42 PM CET wallabag

Claims As Volumes 

Pods access storage by using the claim as a volume. Claims must exist in the same namespace as the Pod using the claim. The cluster finds the claim in the Pod's namespace and uses it to get the PersistentVolume backing the claim. The volume is then mounted to the host and into the Pod.

PersistentVolumeClaims 

Each PVC contains a spec and status, which is the specification and status of the claim. The name of a PersistentVolumeClaim object must be a valid DNS subdomain name.
