Mount EBS Volume EC2 User Data

This repository provides a Go-based application to automate the process of mounting an EBS volume on an EC2 instance.

Features

• Waits for the EBS volume to be attached.
• Creates a folder for mounting the EBS volume if it doesn't exist.
• Checks if the volume is already mounted.
• Creates a file system on the EBS volume if necessary.
• Mounts the EBS volume to the specified folder.

Environment Variables

The application uses the following environment variables:

• EBS_VOLUME_DEVICE_NAME: The device name of the EBS volume (e.g., sdh).
• EBS_FOLDER_PATH: The folder path where the EBS volume will be mounted.
• WAIT_EBS_VOLUME_FOLDER_RETRTY_INTERVAL: Retry interval (in seconds) for checking if the EBS volume is attached.
• WAIT_EBS_VOLUME_FOLDER_MAX_RETRY: Maximum number of retries for checking if the EBS volume is attached.

Example Usage in EC2 User-Data

Add the following script to your EC2 instance's user-data script:

MOUNT_VOLUME_BINARY_URL=https://github.com/robsoned/mount-ebs-volume-ec2-user-data/releases/download/0.0.2/mount-ebs-volume-ec2-user-data-0.0.2-linux-amd64.tar.gz

curl -L $MOUNT_VOLUME_BINARY_URL -o /tmp/mount-ebs-volume-ec2-user-data.tar.gz && \
tar -xzf /tmp/mount-ebs-volume-ec2-user-data.tar.gz -C /tmp

EBS_VOLUME_DEVICE_NAME=/dev/sdh \
WAIT_EBS_VOLUME_FOLDER_RETRTY_INTERVAL=10 \
WAIT_EBS_VOLUME_FOLDER_MAX_RETRY=10 \
EBS_FOLDER_PATH=/home/ec2-user/ebs-volume \
/tmp/mount-ebs-volume-ec2-user-data

Note: Remember to update the environment variables, such as EBS_VOLUME_DEVICE_NAME, to match your specific configuration as needed.

Important: This script must be run as the root user, or with sudo privileges.
