Airport-Finder

A simple project to use as a tool to practice the lessons learned at the SUSE Cloud Native Foundations Scholarship.

If you want to test it, you'll need to have an account for the MaxMind GeoIP2 service (free account) see https://www.maxmind.com/en/geoip2-services-and-databases.

##Testing in Kubernetes Once you have vagrant up & running using the Vagrantfile in the home directory and you have k3s installed (installation instructions here ):

Note: There is a bug in Windows with Hypervisor & K3s so until is is solved, you should install version v1.20.7+k3s1 with curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.20.7+k3s1 sh

Move to the /vagrant/deployment directory

Create the namespace

kubectl apply -f namespace.yaml

Create the empty secrets holder

kubectl apply -f airport-finder-secrets.yaml

Add the real secrets

Create a file named geoip2.account-id with the id, and another one named geoip2.license-key with the license key, of your MaxMind GeoIP2 service account.

No worries, git is configured to ignore those files so they won't be added to the source repository.

Add the id and license to the secrets

Run the following command to patch the secrets with the data: kubectl create secret generic airport-finder-secrets --save-config --dry-run=client --from-file=./geoip2.account-id --from-file=./geoip2.license-key -o yaml | kubectl apply -f -

Deploy the application

kubectl apply -f airport-finder-deployment.yaml

Create the service to support the application

kubectl apply -f airport-finder-service.yaml

Set up your default context to be 'scnfs-demo'

kubectl config set-context --current --namespace=scnfs-demo

Prepare the script to find the pod name to use in commands'

alias findpod='POD=$(kubectl get pod -l app=airport-finder -o jsonpath="{.items[0].metadata.name}")'

Check that the pod and the service are up & running

kubectl get all

Check that the pod details

findpod;kubectl describe po $POD

Check pod logs

findpod;kubectl logs --follow $POD

Open a terminal in the log, in case you need to check things

findpod;kubectl exec --stdin --tty $POD -- /bin/bash

To remove the service and deployment

kubectl delete -f airport-finder-deployment.yaml

kubectl delete -f airport-finder-service.yaml

Creating the docker image locally

mvn package jib:dockerBuild
