# Create Docker Image of your Spring Boot app.
# Run your Spring Boot application in Docker container and connect to Postgres in Docker.
- This project demonstrates starting a Spring Boot app in a docker container.
- It uses Docker compose to run the Spring Boot app connected to Postgres DB with all of these running in their own separate containers.
# Updated Simple Steps to run the project
Step 0: Make sure docker is installed and running.
Step 1: Set the environment variable for Postgres DB password like this
`export POSTGRES_DB_PWD=admin`
Step 2: Run docker compose up:
`docker compose -f ./docker-compose.yaml up`
- Note: The updated DockerFile has multi-stage build that produces the jar file to be used by docker compose
# (Deprecated) Steps to run the project
Step 0: Make sure docker is installed and running.
Step 1: Build the project to create the .jar file (`./mvnw clean package -DskipTests`) (If needed, `chmod +x mvnw`)
Step 2: Set the environment variable for Postgres DB password like this
`export POSTGRES_DB_PWD=admin`
Step 3: Run docker compose up:
`docker compose -f ./docker-compose.yaml up`
Step 4: Use tool like Postman to send request to the end-point for creating product record and viewing product record:
http://localhost:8081/product-service/addProduct
http://localhost:8081/product-service/getAllProducts
http://localhost:8081/product-service/getProduct/1
## Some important commands
- Get inside a Docker container's terminal
`docker exec -it /bin/bash`
- `psql -U postgres`: To start psql for Postgres once inside the container.
- CLI commands for Postgres: `\l` to see the databases, `\c` to connect to a specific database, `\dt` to see the tables
- Up docker containers/services
`docker compose up -d` (use without -d if you need to see the logs)
`docker compose -f ./docker-compose.yaml up`
- Down the docker containers/services
`docker compose down`
- Build docker image of your Spring boot app using Dockerfile
`docker build -t docker-springboot:1 .`
- Run your newly created image in docker
`docker run -p 8081:8081 docker-springboot:1`
