EFS AWS labs step by step

Step 1: Set Up Your AWS Account

1. Sign In: Log into your AWS Management Console.
2. IAM User: Ensure you have an IAM user with appropriate permissions (AmazonElasticFileSystemFullAccess).

Step 2: Create an EFS File System

1. Navigate to EFS:

   • In the AWS Management Console, search for “EFS” and select Elastic File System.

2. Create File System:

   • Click on Create file system.
   • Select your VPC and availability zones.
   • Choose the performance mode (General Purpose or Max I/O) based on your use case.
   • Configure throughput mode (Bursting or Provisioned).
   • (Optional) Enable encryption at rest and in transit.
   • Click Create file system.

Step 3: Configure EFS Mount Targets

1. Mount Targets:
   • After creating the file system, click on it to view details.
   • Click on Network and then Add mount targets.
   • Select subnets (in different availability zones for redundancy).
   • Specify security groups to control access.
   • Click Add mount targets.

Step 4: Create an EC2 Instance to Access EFS

1. Launch EC2 Instance:
   • Navigate to EC2 in the AWS Management Console.
   • Click on Launch Instance.
   • Choose an Amazon Machine Image (AMI), such as Amazon Linux 2.
   • Select an instance type (e.g., t2.micro for testing).
   • Configure network settings to ensure the instance is in the same VPC as the EFS.
   • (Optional) Create or select an existing security group allowing NFS access (port 2049).
   • Click Launch.

Step 5: Install NFS Client on EC2

1. Connect to EC2 Instance:

   • Use SSH to connect to your EC2 instance.

2. Install NFS Utilities:

   bash
   
   sudo yum install -y nfs-utils  # For Amazon Linux
   

Step 6: Mount the EFS File System

1. Create a Mount Point:

   bash
   
   sudo mkdir /mnt/efs
   

2. Mount EFS:

   • Use the EFS DNS name to mount:

   bash
   
   sudo mount -t nfs4 <EFS-DNS-NAME>:/ /mnt/efs
   

   • Replace <EFS-DNS-NAME> with the actual DNS name from your EFS console.

3. Verify Mount:

   bash
   
   df -h
   

Step 7: Test EFS

1. Create a Test File:

   bash
   
   echo "Hello EFS" | sudo tee /mnt/efs/testfile.txt
   

2. Verify File:

   bash
   
   cat /mnt/efs/testfile.txt
   

Step 8: Configure Automatic Mounting (Optional)

1. Edit fstab:

   • Open the fstab file:

   bash
   
   sudo nano /etc/fstab
   

2. Add EFS Entry:

   • Add the following line at the end of the file:

   javascript
   
   <EFS-DNS-NAME>:/ /mnt/efs nfs4 defaults,_netdev 0 0
   

3. Test fstab:

   bash
   
   sudo umount /mnt/efs
   sudo mount -a
   

Step 9: Clean Up

1. Unmount EFS:

   
   sudo umount /mnt/efs
   

2. Delete EC2 Instance:

   • Navigate to the EC2 console and terminate the instance.

3. Delete EFS File System:

   • Go back to the EFS console and delete the file system.
