docker run -d --name my_postgres -v my_dbdata:/var/lib/postgresql/data -p 54320:5432 -e POSTGRES_PASSWORD=my_password postgres:13

• For connection to container "my_postgres":

Mac OS:

sudo docker exec -it my_postgres psql -U postgres

Windows/GitBash:

winpty docker exec -it my_postgres psql -U postgres

• For creation database "requests":

CREATE DATABASE requests;

2. Application from Idea:

• Run RequestsApplication class as usual
• Build frontend-for-backend running from the root dir: sh ./infrastructure/rebuild-frontend-for-backend.sh
• Enjoy at http://localhost:8080

3. Application as standalone jar

• Build it

./mvnw clean package -Dmaven.test.skip=true

java -jar ./target/requests-0.0.1-SNAPSHOT.jar

• Enjoy at http://localhost:8080

4. Application in Docker container

• Build jar:

./mvnw clean package

• Build image of application with name "requests" and tag "latest":

./mvnw jib:dockerBuild -Djib.to.image=requests -Djib.to.tags=latest

• Create network "network_name":

docker network create --driver bridge network_name

• Run container with database and application in one network "network_name":

docker run --name my_postgres --network=network_name -e POSTGRES_PASSWORD=my_password -d postgres:13

docker run -p 8080:8080 --network=network_name -e SPRING_DATASOURCE_URL=jdbc:postgresql://my_postgres:5432/requests requests:latest

• Enjoy at http://localhost:8080/

How to deploy

Server preparation

1. Install Docker engine for your OS.
2. Clone requests-infrastructure repository on server
3. Create file .env in root of requests-infrastructure and add:

POSTGRES_USER=TYPE USERNAME HERE
POSTGRES_PASSWORD=TYPE PASSWORD HERE

4. Install Nginx and use configure file from here

On your machine:

• build jar and docker image of Spring Boot with tag "latest":

./mvnw clean package

docker login

./mvnw jib:dockerBuild -Djib.to.image=bulatzalyaliev/requests -Djib.to.tags=latest

docker push bulatzalyaliev/requests:latest

On server:

• update containers using new images from Dockerhub

sudo docker pull bulatzalyaliev/requests:latest
sudo docker-compose up -d

• Checking work with:

curl http://localhost:8080/api/requests
