Catalog service application is a distributed microservice architecture deployed on Kubernetes.
Notes on the project
- Refresh service configuration by enabling actuator in application.yml then calling http POST <service_url>/actuator/refresh
- Run a Postgres SQL server on Docker:
a. Create network: docker create network catalog-network;
b. Create Postgres container:
docker run -d \
--name polar-postgres \
--net catalog-network \
-v ~/postgress:/var/lib/postgresql/data \
-e POSTGRES_USER=postgres \
-e POSTGRES_PASSWORD=password \
-e POSTGRES_DB=polardb_catalog \
-p 5432:5432 \
postgres:latest
Then get container ID by running <i>docker ps</i> and connect inside the container with <i>docker exec -it <container_id> bash</i>
root@05b3a3471f6f:/# psql -U postgres
postgres-# \l
From outside container, connect to server <i>psql -h <public-ip-server> -p 5432 -U postgres</i>, provide password and list databases <i>postgres=# \l</i>
c. Create catalog-service Docker container image:
docker build -t catalog-service .
d. Run container:
docker run -d \
--name catalog-service \
--net catalog-network \
-e SPRING_DATASOURCE_URL=jdbc:postgresql://polar-postgres:5432/polardb_catalog \
-e SPRING_PROFILES_ACTIVE=testdata \
-p 9001:9001 \
catalog-service
e. Remove PostgreSQL and Catalog Service containers:
docker rm -vf catalog-service polar-postgres
