This component requires the photo-gallery-common
library. Make sure you build that library first.
You can build this project using:
mvn clean install package
This component requires access to a PostgreSQL database. You can create it using:
psql -c 'CREATE DATABASE likedb'
psql -c "CREATE USER likeuser WITH ENCRYPTED PASSWORD 'password'"
psql -c 'GRANT ALL PRIVILEGES ON DATABASE likedb TO likeuser'
You can run this component as a standalone service using:
java -jar target/photo-gallery-like-1.0-SNAPSHOT-runner.jar
After the service starts up you can test it using curl.
To add some likes to the photo with ID 2:
curl -v -X POST -H 'Content-Type: application/json' --data '{"id":"2","likes":"5"}' localhost:8081/likes
curl -v -X POST -H 'Content-Type: application/json' --data '{"id":"2","likes":"2"}' localhost:8081/likes
To retrieve likes received by all photos:
curl -v localhost:8081/likes
Create a new project if it doesn't exist:
oc new-project photo-gallery-distributed
Deploy a PostgreSQL database:
oc new-app \
--template postgresql-persistent \
--param DATABASE_SERVICE_NAME=postgresql-like \
--param POSTGRESQL_USER=likeuser \
--param POSTGRESQL_PASSWORD=password \
--param POSTGRESQL_DATABASE=likedb
Define a binary build (this will reuse the Java artifacts will built previously):
oc new-build \
--name like \
--binary \
--strategy docker
Correct the Dockerfile location in the build config:
oc patch bc like -p '{"spec":{"strategy":{"dockerStrategy":{"dockerfilePath":"src/main/docker/Dockerfile.jvm"}}}}'
Start the binary build:
oc start-build \
like \
--from-dir . \
--follow
Deploy the application:
oc new-app \
--image-stream like \
--name like \
--env QUARKUS_DATASOURCE_URL=jdbc:postgresql://postgresql-like:5432/likedb
Expose the application to the outside world:
oc expose svc like
