In this tutorial, we will explore how to mount an Elastic File System (EFS) on an EC2 Linux instance in a separate AWS account. Elastic File System (EFS) is a scalable and fully managed file system that can be shared across multiple EC2 instances. It provides scalable storage capacity and performance, making it a great choice for scenarios where multiple EC2 instances need to share files.
To begin, we will first cover the process of mounting EFS on EC2 instances. We will then move on to exploring how to mount EFS on an EC2 Linux instance in a separate AWS account, enabling file sharing between instances in different accounts.
Mounting EFS on EC2 instances is a straightforward process. You can achieve this by following these steps:
<ol>
<li>Create an Elastic File System (EFS) in the AWS Management Console.</li>
<li>Launch an EC2 Linux instance and note down its ID.</li>
<li>Install the necessary packages on the EC2 instance to mount EFS.</li>
<li>Mount the EFS on the EC2 instance using the mount command.</li>
</ol>
Once you have successfully mounted the EFS on an EC2 instance, you can share files between multiple instances. However, if you want to mount EFS on an EC2 instance in a separate AWS account, you will need to perform a few additional steps.
To mount EFS on an EC2 Linux instance in a separate AWS account, follow these steps:
<ol>
<li>Create an Elastic File System (EFS) in the AWS Management Console in the desired AWS account (Account A).</li>
<li>In Account A, create a new Security Group that allows inbound traffic on port 2049 from the AWS account you want to mount the EFS in (Account B).</li>
<li>In Account B, retrieve the EFS file system ID and Mount Target IP addresses from Account A.</li>
<li>Launch an EC2 Linux instance in Account B and note down its ID.</li>
<li>Install the necessary packages on the EC2 instance in Account B to mount EFS.</li>
<li>Mount the EFS on the EC2 instance in Account B using the mount command, specifying the Mount Target IP address.</li>
</ol>
By following these steps, you will be able to mount an Elastic File System (EFS) on an EC2 Linux instance in a separate AWS account, enabling file sharing between instances in different accounts. This can be useful in scenarios where you want to securely share files between software development environments or multiple teams working on a project in different AWS accounts.
