![]() ![]() It is the responsibility of the developer to create and publish (if required) the docker image of the application that he has developed. We have to create it for our application. ![]() Where we can find the docker image for the spring boot application that we have developed? Nowhere. It was easy to create a container for MySQL server as there is an already published docker image for MySQL. Now our next target is to create a container for running spring boot application.Ĭreate docker container for Spring Boot Application. Now we have a MySQL docker container up and running. The rest of the parameters are used to create the root password, database and creating the user (with username and password) for giving the access to the database. Mysql is the image name and latest represents the tag This describes the image name and the tag. In this case it is “ mysql-docker-container” Here is the screen shot of successful connection to docker container with Sequel Pro So the outsiders can access the MySQL container with host machine ip-address:2012 port. We have mapped/bind the 3306 port to the 2012 post of the host machine. Then it will be possible to access the mysql docker container through the IP and PORT of the Host machine.Ģ012:3306 :- By default MySQL server uses port 3306. Therefore we need to bind the container port to a port of the host machine. sometimes you might need to connect to MySQL container from host or some other remote sever. p flag is used for port binding between host and container. If you want the terminal access, simply avoid this flag. We use this flag to run the container in detached mode, which means that it will run in a separate background process. Lets break and understand the above “ docker run” command. name mysql-docker-container \ -e MYSQL_ROOT_PASSWORD= root123 \ -e MYSQL_DATABASE= spring_app_db \ -e MYSQL_USER= app_user \ -e MYSQL_PASSWORD= test123 \ mysql:latestĪfter running the above command it will create a docker container with name “ mysql-docker-container“. If it is not available, it will pull the image from the remote repository( Docker Hub) and create the container. It will first check the local docker registry for finding the requested mysql image. Therefore we can create the MysQL docker container executing the following command. MySQL Team has provided an official docker image of MySQL through Docker Hub. A Container for running the MySQL Server (mysql docker image)Ĭlick here If you want to see a list of important and frequently required Docker Commands.A Container for running the Spring Boot Application (developed application docker image).Therefore we need to create following containers in the process of migrating this application for the docker platform. If you have gone through the above reference article ( Simple CRUD Application with Spring Boot and Spring Data JPA), the application has following components and dependencies. Starting to migrate the application to use Docker The fully docker migrated source code( the outcome of this article) can be found at GitHub. As i have already mentioned, we will be adding some docker related configurations to use docker for building and running this application. The initial source code of this article can be found at the article of Simple CRUD Application with Spring Boot and Spring Data JPA . That is “ without docker-compose approach” In this article we will be focusing on the second approach. manually managing and running the dependencies and link them ( without docker-compose).Using docker-compose for managing and running dependencies (servers) and link them.There are two main ways that can be used to build and run applications with docker. If you want to learn them, please refer my blog article of Simple CRUD Application with Spring Boot and Spring Data JPA. Since the purpose of this article is to demonstrate the features and capabilities of the Docker, i am not going to explain the Spring Data JPA related code here. So in this article, we will try to use docker based mysql container for replacing the traditional MySQL server (The MySQL server that is run as a external sever). The existing application is a Spring Boot REST Api application that uses Spring Data JPA for persistent layer and MySQL as the database server. Here we will be migrating an existing application to use docker based containers instead of traditional pre installed servers. So if you are new to docker, please read the following article, before continuing with this article.Ĭlick here to go to the article of “What is Docker and Its Overview” The basic introduction and overview of the docker can be found at following blog article.
