• Getting back to writing notes after two months.
• Lots has happenend in that time.
• Need to redo all the work I do and reshuffle them through the day
• BIG Idea: Focus hours first thing in the day. Four hours. One half hour break in the middle
• So the three Ss in the morning. meditation, back physio, making breakfast, feeding the pups in the morning
• Then, start with the focus task of the day
• Then, break for lunch and a nap
• Then, French, and misc work (calendar/org tasks, system updates) and pottering about the house
• Tea, followed by a walk
• OSS work
• Next self learning / hobby block. (Rustlings or Writing posts or working on Rust projects)
• End with planning the day next, before turning in for dinner and bed

• And so we begin! Starting up where I left in the Bootstrapping Microservices Book
• 2025-10-20 08:55: Going well so far. There are distractions, but not much
• Refamiliarised myself and got myself up to speed, much faster than usual
• Best to have two separate Dockerfiles according to the book:

  We can get away with having a single Docker Compose file that is parameterized by an environment variable, but I generally keep separate versions for testing development and production.
  That’s because I like to have my production Docker Compose file mimic the real production environment as much as feasible. In addition, usually my development version will replace various microservices with mock versions for easier and faster testing, but when testing in production mode, it’s better to test the real microservices and not the mock versions.

• 2025-10-20 09:35: Saw an example of containers communicating directly with http
• Learnt how to be dangerous with mongosh
• 2025-10-20 10:00: Tea break

2025-10-20 10:30

• Back
• 2025-10-20 10:58: Got through whole chapter! On to chapter 6!
• Updating kind on my machine
• Learned that kind lets me have as many “nodes” as I want. This tiny snippet gives me a control plane and two nodes!

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
name: my-humongous-cluster
nodes:
 - role: control-plane
 - role: worker
  - role: worker

• Kind has no access to my locally built images. I need to load them in …

kind load docker-image <image-name:n> # n is a version number tag

• 2025-10-20 12:50: Done for the day. Good progress
  Had issues with kind. Will investigate Minikube tomorrow.
