Docker, Kubernetes & Go — Hands-on Notes

Golang, Docker and Kube Practice session

Kubernetes 1.6+

Quotes to spice my work

“Innovation is taking two things that already exist and putting them together in a new way.”

• Tom Freston

“What's measured improves” ― Peter Drucker

“It's not about your resources, it's about your resourcefulness .”

• Tony Robbins

Docker Desktop alternate

https://github.com/abiosoft/colima

## colima start --arch x86_64 --vm-type=qemu --cpu 8 --memory 16 --disk 100 --kubernetes
# To start colima with Kubernetes with x86_64 architecture
colima start
docker build . && docker ps -a 
colima stop

Helm

brew install helm

Automated PR

brew install github/gh/gh
git add .
git commit -am "just testing"
gh pr create -f

Go WorkSpace

Go1.18 feature of Go Workspace is enabled here.

cd ~/code/Devops
cd ..
go work init ./Devops (Note go.wrk file will be created, and ENV variable was assigned)
go work sync

Create Nginx Service

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update

https://github.com/kubernetes/ingress-nginx/tree/master/charts/ingress-nginx

helm install -f minikube/nginx/values.yaml nginx ingress-nginx/ingress-nginx

$ minikube service ingress-nginx-controller  --url
http://192.168.99.100:32080
http://192.168.99.100:31443
http://192.168.99.100:32443

Add awesome-http.example.com in /etc/hosts to connect local

curl http://awesome-http.example.com/dev
curl http://awesome-http.example.com/dev/metrics

Kind environment

Install colima from previous steps, to run Kind we need docker engine is running.

colima start

Testing in kind cluster, port mapping required for docker image of Kube worker node. So please make sure extra port mappings are added in the kind/config.yaml Remember to add in /etc/hosts (to nginx to work)

Mongo

To run mongo in local MAC, run the Make commands, this will be helpful for local testing. make run-mongo

Clean the logs, kill the process if not required.

GIT FLOW

I created GIT FLOW using the same nvie git flow, but added two release to understand better.

sequenceDiagram
    autonumber
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->>John: Fight against hypochondria
    end
    Note right of John: Rational thoughts!
    John-->>Alice: Great!
    John->>Bob: How about you?
    Bob-->>John: Jolly good!
