![]() You can test this with a second container running mongosh on the same network. docker run -name mongodb -d -network mongodb mongodb/mongodb-community-server:$MONGODB_VERSION With this method, you will connect to MongoDB on mongodb://mongodb:27017 from the other containerized applications in the network. If your application is running inside a container itself, you can run MongoDB as part of the same Docker network as your application using -network. If you stop and start the container again, all the data you entered previously will still be there. docker run -name mongodb -d -p 27017:27017 -v $(pwd)/data:/data/db mongodb/mongodb-community-server:$MONGODB_VERSION If you want to persist the data on your local machine, you can mount a volume using the -v argument. You can do that with the Docker stop and rm commands. ![]() You can try it with Compass, MongoDB’s GUI to visualize and analyze your data.Īny data created as part of the lifecycle of that container will be destroyed once the container is deleted. Using this method, you will be able to connect to your MongoDB instance on mongodb://localhost:27017. docker run -name mongodb -d -p 27017:27017 mongodb/mongodb-community-server:$MONGODB_VERSION If you need to access the MongoDB server from another application running locally, you will need to expose a port using the -p argument. As a best practice, it’s recommended to use a tag to specify the MongoDB version to ensure consistency. This command will start a MongoDB server running version 6.0 based on the Red Hat UBI in detached mode (as a background process). export MONGODB_VERSION=6.0-ubi8ĭocker run -name mongodb -d mongodb/mongodb-community-server:$MONGODB_VERSION Start by setting the version you want to use in a variable. You can start a MongoDB container using Docker with the following command. You can find the installation instructions for your operating system on their website. In order to run the following instructions, you will need to install Docker Desktop. In the following sections, you'll learn some methods to run and manage containers with MongoDB. There are many ways to use MongoDB in a containerized environment. Tools such as Kubernetes will help you to manage these containerse, and the Kubernetes Operators can help you with setting up the persistent volumes. ![]() If you need to preserve data, you will need to mount a volume which is accessible from the container. On the other hand, this can be somewhat challenging when preserving data is necessary, as would be the case when running a container for a database. It is also an excellent feature for software developers running tests on their system since any data entered would be deleted, and the test run would start fresh each time. This is great to ensure that the application always runs consistently. When a container is restarted, it will always be the same, and any change that might have occurred while it was running is now gone. Orchestration tools such as Kubernetes also make it simple to upgrade unique microservices without any downtime.Īnother benefit of using containers is that they are ephemeral in nature. Containers also make it possible to have small microservices running together side by side. Their small footprint makes it easy to run multiple self-contained and isolated applications. Therefore, the total cost of running an application as a container is much smaller than running it on a virtual machine.Ĭontainer technology is also at the heart of the microservices revolution in software development. This has the benefit of significantly reducing the resources needed to run compared to virtual machines, which require a full operating system of their own. Thanks to that engine, a container can run uniformly on Linux, macOS, and Windows.Ĭontainers run as single processes on the Docker engine.Ĭontainers run in their own isolated processes in a given user space. Docker popularized the concept of containers when they introduced the Docker Engine, which lets containers run on any operating system. Containers are a way to isolate everything needed to run an application in its environment. This was the beginning of process isolation.įast forward a few years, and you get the state of containers as they are today. The chroot command was introduced as part of the operating system, which changes the root directory of a process and its children. It finds its roots with the advent of the Unix operating system. The concept of containers dates back to the ’70s. Docker is a tool to run those containers. Imagine a big zip file that would include everything needed to run your application on any operating system or hardware. A Docker container is a single unit containing an application and all of its necessary configurations or dependencies.
