Learn how to migrate AWS SES email templates between accounts using a Bash script. A practical guide for those less technically inclined.

Amazon Web Services (AWS) Simple Email Service (SES) is a reliable and cost-efficient way to manage email communications, essential for both transactional messages and marketing campaigns. While AWS SES boasts numerous advantages, one might encounter difficulties in managing email templates across various regions or accounts, particularly for those not well-versed with the AWS Command Line Interface (CLI) or SES API. This guide aims to introduce a method for moving AWS SES email templates from one account to another using a Bash script, offering an alternative to the previously discussed Python approach.

Understanding the Complexity of AWS SES

AWS SES is celebrated for its affordable email delivery services, catering to a wide range of business needs. However, its intricacies, especially concerning the API and CLI, pose a challenge for users lacking a technical foundation. This challenge is accentuated when there's a need to move email templates between AWS accounts or regions, a task often encountered during various phases of software development and deployment.

The Solution: Bash Script for Email Template Migration

Rather than using a Python script, this solution leverages a Bash script to copy or move SES email templates between AWS accounts or regions. This method requires basic familiarity with AWS and the ability to manage security credentials.

Prerequisites

  • Basic knowledge of AWS and how to retrieve security credentials.
  • AWS CLI installed and configured on your system.

Step 1: Setting Up Your Environment

Ensure the AWS CLI is installed and properly configured on your machine. This is a crucial step for managing AWS resources from your local environment.

Step 2: Configuring AWS Credentials

To interact with AWS services, like moving SES email templates, you must configure your AWS credentials. This can be done through AWS CLI profiles or by setting environment variables. Both methods are viable for different scenarios, with CLI profiles being ideal for managing multiple credential sets and environment variables suited for dynamic configurations.

Using AWS CLI Profiles:

  • Install the AWS CLI if it's not already installed.
  • Configure profiles using the aws configure command, providing access key ID, secret access key, default region, and output format for both source and target profiles.
aws configure --profile source_profile aws configure --profile target_profile

Step 3: The Bash Script for Migration

The core of this approach involves a Bash script that lists all email templates from the source account, retrieves each template, and then creates or moves them to the target account. This script simplifies the migration process, making it accessible to those preferring command-line tools over programming scripts.

Create a new file called migrate.sh and paste the following contents:

#!/bin/bash # Define AWS profile names for source and target accounts SOURCE_PROFILE=source_profile TARGET_PROFILE=target_profile # List all templates from the source account TEMPLATE_NAMES=$(aws ses list-templates --profile $SOURCE_PROFILE --query 'TemplatesMetadata[*].Name' --output text) # Loop through each template name and migrate to the target account for TEMPLATE_NAME in $TEMPLATE_NAMES; do # Retrieve the template from the source account TEMPLATE_JSON=$(aws ses get-template --profile $SOURCE_PROFILE --template-name $TEMPLATE_NAME --output json) # Create or move the template in the target account echo "Migrating template: $TEMPLATE_NAME" aws ses create-template --profile $TARGET_PROFILE --cli-input-json "$TEMPLATE_JSON" done echo "Migration completed." This script leverages the AWS CLI to interact with SES, automating the process of migrating email templates between accounts. It's a straightforward, command-line-based solution that caters to both technical and less-technical users comfortable with basic scripting. You can execute the script by running ```bash ./migrate.sh

within the same directory.

Conclusion

While the Python script offers a programmable way to migrate SES email templates, using a Bash script provides a simpler, more direct method for those familiar with the command line. This approach reduces the complexity associated with AWS SES template migration, allowing users to efficiently move, copy, or migrate templates across accounts or regions, thus ensuring a smoother management process for email communications.
