Docker mongodb3.6

Using docker to create an image and container for the mongodb to run on.

Docker

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and deploy it as one package.

Dockerfile

A dockerfile is a script with various commands and arguements listed successively to automatically perform actions on a base image to create a new one. In this case we used an existing mongo image with version 3.6.18 on an xenial base image and replace the mongod.conf.

Running the app

to build an image:

docker build . -t mongodb3.6

to run image:

docker run -d --name mongodb3.6 -p 27017:27017 mongodb3.6

to stop running container:

docker stop mongodb3.6

to remove container

docker rm mongodb3.6

Docker Hub

Docker Hub is a cloud-based repository in which you can create, test, store and distribute container images. We can use this to create our own repository for this Hackerank API.

Using Docker Hub

The first thing you need to do is to create a Docker Hub account, and then create a repository and give it a name.

Once the container is running, you can push the image to the repository you created.

Then need to commit the project:

docker commit -m 'commit message' <image_name> <username/repository_name>

Push the project to Docker Hub:

docker push <username/repository_name>
