Enable `systemd` in WSL2 Debian 11

This guide will help you install systemd to run as normal under WSL2 Debian. This will allow services like microk8s, docker, cockpit and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 21H2, running Debian 11 in WSL2.

To enable systemd under WSL we require a tool called systemd-genie
Download install-sg.sh to a temporary location /tmp:

cd /tmp

FAQ

Q: pointers vs values (in general) ?

A:

Don't pass pointers as function arguments just to save a few bytes.

Don't pass a pointer to a string (*string) or a pointer to an interface value (*io.Reader). In both cases the value itself is a fixed size and can be passed directly.

Use pointes on large structs, or even small structs that might grow.

List evicted pods

kubectl get pods --all-namespaces -o json \
  | jq -r '.items[] | select(.status.reason == "Evicted") | "pod/\(.metadata.name) -n \(.metadata.namespace)"'

Delete evicted pods

1. I am interested in monitoring traefik with Datadog. Is this workshop with this topic?

There is no dedicated workshop with the monitoring Traefik by using Datadog. I’ve found in Datadog docs how to configure DataDog Agent and tune Traefik configuration to collect the data. However, I’ve not tested that setup.

2. In terms of Capabilities, how would Traefik provide a value add over some in-built services such as Azure LB or App Gateway?

Here are just a few of advantages by using Traefik:

easier configuration / service discovery
single point TLS termination

Even bad code can function. But if code isn't clean, it can bring a development organization to its knees.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.
