Introduction

In this article, we will discuss the recent update to the Amazon Corretto 8 JRE, specifically the introduction of a new .msi installer. We will explore the implications of this change, how it affects users, and the necessary steps to update the application manifest file to reflect this addition. The focus will be on ensuring that Evergreen, a popular application management tool, can accurately detect and deploy the new .msi installer.

Background on Amazon Corretto 8

Amazon Corretto 8 is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK) 8. It is designed to provide long-term support and is used by many organizations for running Java applications in various environments, including cloud and on-premises. Corretto 8 is known for its stability, performance, and security updates, making it a reliable choice for Java runtime environments. Regular updates and improvements are crucial to maintaining a secure and efficient Java ecosystem.

The New .msi Installer

Recently, Amazon Corretto 8 introduced a new .msi installer, which simplifies the installation process on Windows systems. The .msi format is widely used for installing applications on Windows because it provides a consistent and reliable installation experience. Unlike the previous .zip archive, the .msi installer offers several advantages, including:

  • System Integration: .msi installers integrate seamlessly with Windows, making it easier to manage the JRE using system tools.

The Issue: Evergreen App Tracker and .msi Installer

Currently, the App Tracker used by Evergreen (https://stealthpuppy.com/apptracker/apps/a/amazoncorretto8/) only displays the JRE .zip archive. This means that Evergreen, a tool used for managing and deploying applications, does not recognize the new .msi installer. This discrepancy can lead to issues in automated deployment and updating processes, as Evergreen may not be able to detect and install the latest version of Amazon Corretto 8 JRE.

The primary concern is that organizations relying on Evergreen for application management may not be able to leverage the benefits of the .msi installer, such as simplified installation and automatic updates. To address this, the application manifest file needs to be updated to include the .msi installer.

Understanding the App Manifest File

The app manifest file is a crucial component of Evergreen. It contains metadata about applications, including download URLs, versions, and checksums. Evergreen uses this file to determine the latest version of an application and download the appropriate installer. By updating the manifest file, Evergreen can be made aware of the new .msi installer for Amazon Corretto 8 JRE.

Steps to Update the App Manifest File

To ensure Evergreen can recognize and deploy the .msi installer, the following steps need to be taken to update the app manifest file:

  1. Identify the Current Manifest File: Locate the app manifest file for Amazon Corretto 8 within the Evergreen configuration. This file typically resides in a designated directory for application manifests.
  2. Analyze the Existing Entries: Examine the current entries in the manifest file, particularly those related to the JRE. Note the existing download URLs, versions, and checksums for the .zip archive.
  3. Add New Entries for the .msi Installer: Add new entries to the manifest file for the .msi installer. This includes the following information:
  4. Verify the MD5 Checksum: Calculate the MD5 checksum of the .msi installer file using a checksum utility. Ensure that the calculated checksum matches the value entered in the manifest file.
  5. Test the Updated Manifest: After updating the manifest file, test it by running Evergreen and checking if it correctly detects the .msi installer as the latest version. Verify that Evergreen can download and install the .msi package without errors.
  6. Deploy the Updated Manifest: Once the manifest file has been tested and verified, deploy it to the production environment. This will ensure that all systems managed by Evergreen can access and use the new .msi installer.

Practical Example: Adding .msi Entry to Manifest

Here's an example of how to add an entry for the .msi installer to the app manifest file (this is a conceptual example, and the exact format may vary depending on the Evergreen implementation):

{
  "Version": "8.472.08.1",
  "Md5": "5dff20d3c02c755f7d6ffbbbf11db1c2",
  "Architecture": "x86",
  "Type": "msi",
  "URI": "https://corretto.aws/downloads/resources/8.472.08.1/amazon-corretto-8.472.08.1-windows-x86-jdk.msi"
}

This entry provides Evergreen with the necessary information to download and install the .msi version of Amazon Corretto 8 JRE. Ensure that the MD5 checksum is accurate to prevent installation failures due to corrupted files.
