Configuration Files
Folder src/resources/ contains config files for blog-demo Spring Boot application.
- src/resources/application.properties - main configuration file. Here it is possible to change admin username/password, as well as change the port number.
How to run
There are several ways to run the application. You can run it from the command line with included Maven Wrapper, Maven or Docker.
Once the app starts, go to the web browser and visit http://localhost:8090/home
Admin username: admin

User password: password
Maven Wrapper
Using the Maven Plugin
Go to the root folder of the application and type:
$ chmod +x scripts/mvnw
$ scripts/mvnw spring-boot:run
Using Executable Jar
Or you can build the JAR file with
$ scripts/mvnw clean package
Then you can run the JAR file:
$ java -jar target/blog-demo-0.0.1-SNAPSHOT.jar
Maven
Open a terminal and run the following commands to ensure that you have valid versions of Java and Maven installed:
$ java -version
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)
$ mvn -v

Using the Maven Plugin
The Spring Boot Maven plugin includes a run goal that can be used to quickly compile and run your application. Applications run in an exploded form, as they do in your IDE. The following example shows a typical Maven command to run a Spring Boot application:
$ mvn spring-boot:run
Using Executable Jar
To create an executable jar run:
$ mvn clean package
To run that application, use the java -jar command, as follows:
$ java -jar target/blog-demo-0.0.1-SNAPSHOT.jar
To exit the application, press ctrl-c.
Docker
It is possible to run blog-demo using Docker:
Build Docker image:
$ mvn clean package
$ docker build -t blog-demo:dev -f docker/Dockerfile .
Run Docker container:
$ docker run --rm -i -p 8090:8090 \
--name blog-demo \
blog-demo:dev
Helper script
It is possible to run all of the above with helper script:
$ chmod +x scripts/run_docker.sh
$ scripts/run_docker.sh
Docker
Folder docker contains:
- docker/blog-demo/Dockerfile - Docker build file for executing blog-demo Docker image. Instructions to build artifacts, copy build artifacts to docker image and then run app on proper port with proper configuration file.
Util Scripts
- scripts/run_docker.sh.sh - util script for running blog-demo Docker container using docker/Dockerfile
Tests
Tests can be run by executing following command from the root of the project:
$ mvn test
