How to enable YUM version lock in Amazon Linux 2 to prevent Docker 25 update

Important Note: Please consider to create a full backup of your EC2 Instance with an Amazon Machine Image (AMI) or take snapshot of an idividual/multiple EBS volumes.

Run the following script to lock your current Docker version using the yum version lock. This will prevent your Docker package from being automatically updated to a newer version.

#!/bin/bash

# Check if the user is running the script as root
if [ "$(id -u)" != "0" ]; then
   echo "This script must be run as root"
   exit 1
fi

# Install the yum-plugin-versionlock package
yum install -y yum-plugin-versionlock

# Check if the installation was successful
if yum list installed yum-plugin-versionlock >/dev/null 2>&1; then
    echo "The yum-plugin-versionlock package has been installed successfully."
else
    echo "Failed to install the yum-plugin-versionlock package."
    exit 1
fi

# Set the package name and version you want to lock
PACKAGE_NAME="docker"
PACKAGE_VERSION="*"

# Check if the package is installed
if yum list installed "$PACKAGE_NAME" >/dev/null 2>&1; then
    echo "Package $PACKAGE_NAME is installed on the system."
else
    echo "Package $PACKAGE_NAME is not installed on the system."
    exit 1
fi

# Check if the package is already locked
if yum versionlock list | grep -q "$PACKAGE_NAME"; then
    echo "Version lock for $PACKAGE_NAME is already set."
    exit 0
fi

# Lock the package version
yum versionlock add "$PACKAGE_NAME-$PACKAGE_VERSION"
if [ $? -eq 0 ]; then
    echo "Version lock for $PACKAGE_NAME-$PACKAGE_VERSION has been set successfully."
else
    echo "Failed to set version lock for $PACKAGE_NAME-$PACKAGE_VERSION."
    exit 1
fi
