Public Openjre Image vs. Minimus Hardened Openjre Image

Openjre Image Overview

The Openjre image is a lightweight containerized environment designed to run Java applications using OpenJRE. It is commonly used in application development and deployment scenarios that require a reliable Java runtime environment. Known for its performance efficiency, the Openjre image supports scalability and can be easily integrated into various cloud-native architectures. Its flexibility makes it suitable for a wide range of use cases, including microservices, backend systems, and automation scripts.

Minimus Openjre Image

CIS
NIST
FIPS 140-3
STIG
The Minimus Openjre image is a streamlined alternative to typical Openjre distributions, offering enhanced performance and security. Built from scratch with only the essential components, it boasts a reduced attack surface that makes it faster, lighter, and easier to maintain. Integrated threat intelligence allows teams to focus on the vulnerabilities that matter most, while its lean design remains cleaner over time—improving both security and long-term maintainability.

Frequently Asked Questions

Openjre Container Image FAQ

Answers to common questions about Openjre and the Minimus Hardened Openjre Image
What is the purpose of the OpenJRE image?
The OpenJRE image is designed to provide a lightweight runtime environment for executing Java applications without including development tools or a full Java Development Kit (JDK).
How is the OpenJRE image typically used in containerized environments?
In containerized environments, the OpenJRE image is often used as a base image to run Java applications efficiently, reducing image size and minimizing attack surface compared to using a full JDK.
What are the typical limitations of using the OpenJRE image compared to a full JDK image?
The OpenJRE image lacks development tools such as compilers and debuggers; therefore, it is not suitable for building or compiling Java code, and is intended strictly for running pre-built applications.
Can I replace my Openjre image with the Minimus Hardened Openjre Image?
Yes. The Minimus Openjre image contains everything you need to run Openjre successfully.
Does Minimus offer FIPS 140-3 images?
Yes, Minimus images are hardened to CIS and NIST standards, with FIPS 140-3 and STIG ready variants available.
