We observe that once the docker container is removed,  we lose the entire data along with that container and cant recover which was very precious for the business continuity. 😔  Here we will fix the issue by mounting the volume in the docker-compose file. Prerequisites: Basic awareness about Docker containers and how to make it up. Create docker-compose.yaml file as below  This configuration will pull the latest mongo image from the docker hub. Re-creating the data lose Scenario   Execute the docker file using the command docker-compose up -d  "-d" preferable to run in a detached mode run docker ps to check the container status  Will try to launch to mongo terminal by hitting the below command  docker exec -it c6d1608207ca bash (Used container id can use container name also) Once the terminal got opened execute   mongo admin -u root -p example will help to connect to the mong DB view the database using show dbs Now we can create a new database using the command use address

 

 My first upload to the containerized platform Goodbye to the server-based deployments. Feels good and well managed and can be distributed effortlessly. When I executed my first  http://localhost:9000/docker  new journey to the containerization started. Prerequisites I downloaded Docker and installed it in my local machine and created a free account in docker hub ( https://hub.docker.com/ ). Log in to the docker with the docker hub credentials (Right-click on the docker desktop and click sign in) Here goes my sample project set up  pom.xml Created a spring boot application using  https://start.spring.io/  with spring-boot-starter-web dependency. Created one controller to test the application Controller class The key part of the docker containerization is the creation of Docker file note*: Where 'D' should be capital and no extension is required. and the file content is  FROM java:8 -> from java8 image ADD target/springdocker.jar springdocker.jar -> our target jar naming
