Install k8ssandra per k8ssandra.io

helm install -f k8ssandra.yaml k8ssandra k8ssandra/k8ssandra
watch kubectl get pods

User and pass needed for local testing

kubectl get secret k8ssandra-superuser -o jsonpath="{.data.username}" | base64 --decode ; echo
kubectl get secret k8ssandra-superuser -o jsonpath="{.data.password}" | base64 --decode ; echo

Port forwarding for local access

kubectl port-forward svc/k8ssandra-dc1-stargate-service 8080 8081 8082 9042

Use cqlsh to load memegen.cql statements

kubectl exec -it k8ssandra-dc1-default-sts-0 -- bash -c "wget https://raw.githubusercontent.com/ds-steven-matison/MemesGen/master/memegen.cql -P /tmp && /opt/cassandra/bin/cqlsh localhost 9042 -u k8ssandra-superuser -p [pass above] -f /tmp/memegen.cql"

Role out app

kubectl apply -f deployment.k8s.yaml

Access app locally

kubectl port-forward deployments/memegen-v2  1337:80

After port fwd access app @ http://localhost:1337.

Connect to app container

kubectl exec -it deployments/memegen-v2 /bin/bash

💡 Use the command tail -f /var/log/php5-fpm.log to check PHP Errors. You can also find the app source at /usr/share/nginx/html.

Create your own dockerhub image

Current Docker image.

Git clone [this repo]
Next build and push image

docker build . -t dsstevenmatison/memegen2
docker push dsstevenmatison/memegen2

⚠️ This sample above is mine, you would change to your dockerhubrepo/appname. Then in the deployment.k8s.yaml file you reference the full docker.io string to image. For example: docker.io/dsstevenmatison/memegen2:latest.

Edit deployment.k8s.yaml accordingly then

kubectl apply -f deployment.k8s.yaml

If you are just updating the image, murder the pod and it will recreate w/ new image

kubectl delete pod memegen-v2-6fd6b955f6-6ldk5

💡 Monitor your watch kubectl get pods terminal and watch this pod terminate and recreate!!!
