In this tutorial, we are going to creating a CentOS 7 base image for our Atlassian applications.
In our cases, the base image is will be created on an ESXi based virtual machine. If you are using other hypervisor or running on a bare-metal you can also follow this tutorial.
If you are using a cloud provider such as AWS, Google Cloud, DigitalOcean, the base image we are creating is very similar to their image.
