Kubernetes is an open source project designed to automate the deployent, scaling, and management of cloud based applications. Commons uses kubernetes to run in the cloud. Various cloud services provide support for running and monitoring applications in a kubernetes environment. In order to test out and debug issues related to prodution environments developers should run commons using minikube, which allows developers to run kubernetes environments on a single machine. Follow the appropriate install instructions for your machine. Once installed you can use the following command line instructions to run Commons in a cloud-like environment. Note before running the application in kubernetes, [we will need access to an appropriate postgres instance] (## Connecting to postgres from minikube)
minikube start
eval $(minikube docker-env)
packer build -var version=$(git rev-parse --short=8 HEAD) -var container_image_name=swl-eng/commons-nginx deployment/commons_nginx.json
packer build -var version=$(git rev-parse --short=8 HEAD) -var container_image_name=swl-eng/commons-server deployment/commons_server.json

kubectl create secret generic commons-config --from-file=.env=config/development.env

kubectl delete -f deployment/commons_ingress.yml
N.B. Two Things: Dont forget to add your secrets to kubernetes correctly, otherwise you get silent errors Don't forget to turn off your minikube when you're all done, you probably could have guessed:
minikube stopInstall postgres linux
sudo apt-get install libpq-devbrew install postgrescd expo_project
yarnexpo-cli startThere are really basic html forms that allow a user to interact and experiment with firestore. It's a simple static website, with javascript form index.js, and html in index.html. Use your favorite http server from the root directory.
python -m http.servercd deployment
packer build postgres.json
docker run -p 5431:5431 swl-eng/commons-postgres:$(../.version) postgres -p 5431
psql -f deployment/init.sqlThe gcp cloud functions interact with Postgreql. If you're a reasonable human being you want to check the simple stuff really quickly without deploying everyting to the cloud. In the spirit of this, load the sql into a docker container running postgres and test the functions that interact with postgres.
First link the .env file:
ln -s config/development.env .envStart a new environment, currently must be done for each run of a set of test :(
cd deployment && ./develop.shIn order to run test, the jest binary must be available to the execution environment.
yarn run testFollow the instructions to connect to Cloud SQL
cloud_sql_proxy -instances=<INSTANCE_CONNECTION_NAME>=tcp:5432 -credential_file=<PATH_TO_KEY_FILE>Once the cloud sql proxy is running.
psql "host=127.0.0.1 sslmode=disable dbname=postgres user=postgres" -f deployment/reset.sql
psql "host=127.0.0.1 sslmode=disable dbname=postgres user=postgres" -f deployment/init.sql
