docker build -f docker/Dockerfile.gradle-jar -t containerized-app:gradle-jar .
```

#### Multistage
```bash
docker build -f docker/Dockerfile.gradle-multistage -t containerized-app:gradle-multistage .
```

#### Multistage (Gradle Wrapper)
```bash
docker build -f docker/Dockerfile.gradlew-multistage -t containerized-app:gradlew-multistage .
```

#### [Buildpack](https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/htmlsingle/#build-image.examples)
```bash
./gradlew bootBuildImage --imageName=containerized-app:gradle-buildpack
```
```bash
# Build image with git commit id as version
./gradlew bootBuildImage
```

#### [Jib](https://github.com/GoogleContainerTools/jib/blob/master/jib-gradle-plugin/README.md)

```bash
docker build -f docker/Dockerfile.mvn-multistage -t containerized-app:mvn-multistage .
```

#### Multistage (Maven Wrapper)
```bash
docker build -f docker/Dockerfile.mvnw-multistage -t containerized-app:mvnw-multistage .
```

#### [Buildpack](https://docs.spring.io/spring-boot/docs/current/maven-plugin/reference/htmlsingle/#build-image.examples)
```bash
./mvnw spring-boot:build-image -Dspring-boot.build-image.imageName=containerized-app:mvn-buildpack
```
