Remember you can scale down existing pods if you're low on resources:
kubectl scale deploy/products-api deploy/stock-api deploy/web sts/products-db --replicas 0
Deploy the Helm chart to a new namespace using a sample variables file:
helm install widg-uat -n widg-uat --create-namespace -f hackathon/files/helm/uat.yaml hackathon/solution-part-7/helm/widgetario
Check the objects:
kubectl get all -n widg-uat
kubectl get ingress -A
Add hosts for the new domains:
# On Windows (run as Admin)
./scripts/add-to-hosts.ps1 widgetario.uat 127.0.0.1
./scripts/add-to-hosts.ps1 api.widgetario.uat 127.0.0.1
# OR on Linux/macOS
./scripts/add-to-hosts.sh widgetario.uat 127.0.0.1
./scripts/add-to-hosts.sh api.widgetario.uat 127.0.0.1
Try the Products API:
curl -k https://api.widgetario.uat/products
Browse to http://widgetario.uat; you'll see a new Buy button from the latest image update
Deploy the build infrastructure:
kubectl apply -f hackathon/solution-part-7/infrastructure
When it's all running, push your local code to Gogs:
git remote add hackathon http://localhost:30031/kiamol/kiamol.git
git push hackathon main
create registry creds - add your details with variables or use the scripts in the Jenkins lab:
kubectl -n infra create secret docker-registry registry-creds --docker-server=$REGISTRY_SERVER --docker-username=$REGISTRY_USER --docker-password=$REGISTRY_PASSWORD
Create a configmap with the details for the image name - be sure to use a registry and domain you have push access for:
kubectl -n infra create configmap build-config --from-literal=REGISTRY=docker.io --from-literal=REPOSITORY=$REGISTRY_USER
Restart Jenkins to load the latest config:
kubectl rollout restart deploy/jenkins -n infra
Browse to Jenkins http://localhost:30007, sign in with the
kiamolusername and password
Open the Widgetario job in Jenkins, enable and build it. Confirm that your images build and are pushed with the correct tags.
Add the Helm deploy stage to Jenkins:
You can edit the Jenkisfile, or change the job to use the part 7 solution Jenkinsfile:
hackathon/solution-part-7/JenkinsfileBuild again and confirm the latest images are deployed in the new namespace.
Add smoke test domain to hosts file:
# On Windows (run as Admin)
./scripts/add-to-hosts.ps1 widgetario.smoke 127.0.0.1
./scripts/add-to-hosts.ps1 api.widgetario.smoke 127.0.0.1
# OR on Linux/macOS
./scripts/add-to-hosts.sh widgetario.smoke 127.0.0.1
./scripts/add-to-hosts.sh api.widgetario.smoke 127.0.0.1
Check the Products API:
curl -k https://api.widgetario.smoke/products
And test the app at http://widgetario.smoke
