translate-be

This is the backend service for my quick kubernetes demo, it can also be ran as a stand alone service. It simply takes a language code and returns hello world in that language. It relies on Google Translate, which needs to be enabled in the GCP Console. You will also need to set-up a service account and download the private JSON key. More information setting up Google Translate AP can be found here.

The frontend code can be found here.

docker set-up

This can be ran locally as a docker container.

pip3 install -r requirements.txt
docker run -d -p 5001:5001 translate-be

alternatively you can run: docker pull anners/translate-be:latest

python set-up

This can also just be ran as a python/flask app.

pip3 install -r requirements.txt
python3 hello.py

kubernetes quick and dirty set-up

Set up cluster with GKE (or any other way you prefer)

gcloud container clusters create translate

Create a secret with your private key, the deployment file assumes the key is named key.json. If not, update the deployment file.

kubectl create secret generic translate-key --from-file=key.json=<path-to-key>.json

Create the deployment and service

kubectl create -f deployment/translate-be-app.yaml
kubectl create -f deployment/translate-be-service.yaml

Your service should now be available. You can use various kubectl commands to see what is running.

kubectl [get|describe] deployments
kubectl [get|describe] pods
kubectl [get|describe] services

skaffold

Skaffold is a ridiculously easy command line tool that facilitates continuous development for Kubernetes. For information on installing skaffold check out it's GitHub page.

To use it for this project change the image name in skaffold.yaml and deployment/tanslate-be-app.yaml to match your docker repo and simply run skaffold dev
