Welcome

This project contains the artifacts to deploy the Hello World Service via Docker and Kubernetes.

The service connects to a Postgres database to retrieve the welcome message to return.

Build Docker Image

To build the Docker image run the script which gets the service jar:

./build-prep.sh

then:

docker build -t anaxes-hello-world-service .

Run Docker Image

You first need the postgres host. If you run postgres via Docker and have named the container 'postgres' you can get the host from Docker:

SPRING_DATASOURCE_HOST=`docker inspect -f "{{ .NetworkSettings.IPAddress }}" postgres`

Then run the service Docker image on port 8080:

docker run -p8080:8080 -e SPRING_DATASOURCE_URL=jdbc:postgresql://$SPRING_DATASOURCE_HOST/postgres -e SPRING_DATASOURCE_USERNAME=postgres --name hello-world-backend anaxes-hello-world-service:latest

You should then be able to access the REST API at:

http://localhost:8080/hello/welcome
