# Build and Deploy Spring Boot Microservices using Docker
**IMAGE**
Our image will be based on the JDK image.
```python
FROM openjdk:17-oracle
```
**VOLUME**
Take example of a database running in a container. It is important to note that if we delete the container, all the data will be lost. To prevent this, we specify a data folder, in this case, "/tmp".
```python
VOLUME /tmp
```
**Generate JAR**
```python
mvn compile
mvn test
mvn package
==
mvn clean package -DskipTests
```
Jenkins will do this work (this commands) for us after 🙂
**Run JAR**
```python
COPY target/discovery-service-0.0.1-SNAPSHOT.jar app.jar
#COPY target/*.jar app.jar
ENTRYPOINT ["java", "-jar", "app.jar"]
```
**Create image**
```python
docker images
#if file_name = Dockerfile we put . else file_name
docker build . -t discovery-service:version1
```
**Run Container**
```python
#we can also put id "687d1ebc0bf5" instead of name "discovery-service"
docker run discovery-service:version1
```
**Stop container**
```python
#we can just put 2 or 3 chars 787d because id is unique
docker stop 687d1ebc0bf5
```
```python
#dispaly container logs
docker logs 687d1ebc0bf5
```
**Display Containers**
```python
docker ps
```
**Expose our container in externe**
make it accessible
```python
docker run -p 8761:8761 discovery-service:version1
# -p port_in_externe : port_in_container
```
```python
#to run container in background not appear in console
docker run -d -p 8761:8761 discovery-service:version1
```
**Docker Compose**
Now we don’t need to use all past methods
```yaml
services:
ebank-discovery-service:
build: ./discovery-service #go to this folder to find Dockerfile
container_name: ebank-discovery-service
ports:
- '8761:8761'
expose:
- '8761'
healthcheck:
#curl to send an http request to check app health
#-f if we have a fail return fail status code
test: ['CMD', 'curl', '-f', 'http://localhost:8761/actuator/health']
#each 10s we send request default = 30s
interval: 10s
#repeat 5 times
retries: 5
```
```python
docker compose up
#start container in background
docker compose up -d
#if we not use --build docker will not generate an image if it already exist
docker compose up -d --build
```
**Destroy container**
this is why we use VOLUME to save data out of container
```python
docker compose down
```
```yaml
ebank-config-service:
build: ./config-service
container_name: ebank-config-service
ports:
- '9999:9999'
expose:
- '9999'
environment:
#we specify the url of ebank-discovery-service
#we use this variable because if we use localhost docker search in it's own localhost
- DISCOVERY_SERVICE_URL=http://ebank-discovery-service:8761/eureka
depends_on:
ebank-discovery-service:
condition: service_healthy
```
