How to Install MongoDB with Podman on Rocky Linux 8

Leave a comment

In this tutorial I will be showing you how to install MongoDB with Podman on Rocky Linux.

Mongodb is an open source NoSQL database that provides high throughput for data driven applications. Unlike relational databases such as MySQL, Oracle and SQL server which store data in tables according to a rigid schema, MongoDB stores data in documents with flexible schema.

Podman is a daemonless, open source, Linux native tool designed to make it easy to find, run, build, share and deploy applications using Open Container Initiative (OCI) containers and container images.

Complete!

Check version of Podman

$ podman -v
podman version 3.3.1

2. Pull MongoD using Podman

$ podman pull mongo

Choose where you want to pull your image from. For my case I chose Docker, you can use Fedora, Redhat or Centos whichever distro you prefer.

For Docker the output should be like this

✔ docker.io/library/mongo:latest
Trying to pull docker.io/library/mongo:latest...

Check to see the images

$ podman images 
REPOSITORY               TAG         IMAGE ID      CREATED      SIZE
docker.io/library/mongo  latest      4253856b2570  8 hours ago  706 MB

You can test mongodb now with the following:

$ podman run --rm -it mongo

3. Create MongoDB Container

Create a directory to store MongoDB data so that in case you delete the container you will still got your data intact.

$ sudo mkdir data
$cd data

After you have cd into the directory, now you can create your MongoDB container with thefollowing command:

$ podman run --name nextgentipsmongo -d -p 27017:27017 -v $(pwd):/data/db:Z mongo
d495b10f1accd425bd1d13748994b196f4c800344904911a0691146f57bc764e

Let’s look at each command variable:

  • –name: describe the name of the project i.e nextgentipsmongo
  • -d: run your container in detached mode i.e in the background
  • -p 27017:27017: map port 27017 of the host to port 27017 on the container.
  • -v (volume): create persisting data generated and used by podman containers.
  • $(pwd):/data/db: shows the directory to to store your data.
  • :Z– tells podman that the volume content will be shared between containers

4. Test MongoDB

We can test our container to see if it is working with the following command; If it was installed correctly it should show the mongo shell where you can now perform your database routines.

$ podman run --rm -it --network host mongo mongo
MongoDB shell version v5.0.4
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("9a9cc44d-696a-4370-ab0c-bb2d9fe12ded") }

        Enable MongoDB's free cloud-based monitoring service, which will then receive and display
        metrics about your deployment (disk utilization, CPU, operation statistics, etc).

        The monitoring data will be available on a MongoDB website with a unique URL accessible to you
        and anyone you share the URL with. MongoDB may use this information to make product
        improvements and to suggest MongoDB products and deployment options to you.

        To enable free monitoring, run the following command: db.enableFreeMonitoring()
        To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
