If you installed Docker Desktop for either Windows or Mac, you already have Docker Compose Play-with-Docker instances already have Docker Compose installed as well. If you need a refresher on what Docker is capable of, I recommend you to checkout the following first: First Look: Docker for MAC / OSX Using Docker to deploy Apache, Nginx, WordPress and Nodejs containers with Digital OceanSetup Docker Image For Spring Boot ApplicationInstall Docker Compose. In this tutorial, we’ll set up a LEMP stack via Docker and Docker Compose./nginx Custom PHP php.ini config in. This setup comes shipped with: A Dockerfile for extending a base image and using a custom Docker image with an automated build on Docker Hub Custom domain for example myapp.local Custom nginx config in. Use WordPress locally with Docker using Docker compose.
![]() Docker-Compose Mysql Example Docker How To Use DockerGiving created docker image to the docker-compose setup.Let’s go forward with pointing docker file way, since giving docker image part will cover with MySQL image in this same setup. Pointing Dockerfile into the docker-compose setup. FROM openjdk:8-jdk-alpineADD build/libs/spring-boot-mysql-base-project-0.0.1-SNAPSHOT.jar app.jarNow you have two ways of building docker compose setup. Then copy the following content into that file. Then you can use both app and DB images with docker-compose.If you don’t have a good understanding of how to use docker with a spring boot application, you can refer our article on How to Dockerize Spring Boot Application.OK Let’s start the docker image creation,First, create a file naming as Dockerfile in your project root folder. Hence first you need to have docker image for your spring boot application. Methodrequest vcalendar outlook for macSo add the following content into the docker-compose.yml file, version: "3.7" You can use one from the following two methods to build this docker-compose setup.I’ll start with using links to build communication between both. So let’s create the docker-compose.yml file which allows us to combine the Spring Boot application and MySQL database in this setup.First, go to the project root and create a file named docker-compose.ymlSpring-boot-project-with-docker-compose-file Using links to Build Communication Between Services.There are two ways of building communication between spring boot application and the MySQL database. ![]() So internally docker-compose will start dependency services first and it will start dependent service in the end. Using Depends On to Build Communication Between ServicesThe docker-compose documentation specifies that links is deprecated and should be replaced with depends_on.So here I’m setting the same docker-compose setup with using depends_on flag.Just add following into the docker-compose.yml version: "3.7"Command: sh -c './wait-for mysql_db:3306 - npm start'Here we are using depends_on to set dependent services to api_service. Additionally, password and DB has changed accordingly.Better Solution: Use a separate application.properties file for docker-compose based deployments and set that via profiles. Spring.datasource.url=jdbc:mysql://app_db:3306/java_to_dev_app_dbSpring.datasource.password=nE5kMc7JCGNqwDQMSpring.datasource.initialization-mode=alwaysHere as you can see we are using that link value we used in docker-compose definition for host/IP address. ![]()
