The following steps walk you through building a containerized Java Spring Boot web application and testing it locally.įrom the command prompt, use the following command to clone the Spring Boot on Docker Getting Started sample project.

Instead, you should define some basic criteria based on your use case and choose the Docker image that fits best.You can use this Quickstart to build container images of Java Spring Boot app and push it to Azure Container Registry using Maven and Jib. This blog post is intended to make you aware that you should not just randomly select a Java base image. Especially if you use Spring and the official image plugin for Maven and Gradle, you end up with the BellSoft Liberica JDK by default. Nevertheless, other Java vendors are also quite interesting. ![]() Also, the official Maven image supports this Java version, which is a perfect match for me. The image is tiny, meets all my criteria and has almost no vulnerable security holes. Total: 7 (UNKNOWN: 0, LOW: 0, MEDIUM: 1, HIGH: 6, CRITICAL: 0)įor a new project based on Java, I would first choose the Adoptium Eclipse Temurin project. Total: 46 (UNKNOWN: 0, LOW: 5, MEDIUM: 28, HIGH: 8, CRITICAL: 5) Total: 10 (UNKNOWN: 0, LOW: 2, MEDIUM: 2, HIGH: 4, CRITICAL: 2) Total: 10 (UNKNOWN: 0, LOW: 7, MEDIUM: 3, HIGH: 0, CRITICAL: 0) Total: 17 (UNKNOWN: 0, LOW: 13, MEDIUM: 4, HIGH: 0, CRITICAL: 0) Total: 7 (UNKNOWN: 0, LOW: 0, MEDIUM: 2, HIGH: 5, CRITICAL: 0) Total: 0 (UNKNOWN: 0, LOW: 0, MEDIUM: 0, HIGH: 0, CRITICAL: 0) Total: 9 (UNKNOWN: 0, LOW: 0, MEDIUM: 2, HIGH: 7, CRITICAL: 0) Total: 1 (UNKNOWN: 0, LOW: 0, MEDIUM: 0, HIGH: 1, CRITICAL: 0) The results are summarized in the following list (as of November 10, 2022): Name I also checked all these images for security risks using two different image scanners: The heavily used AdoptOpenJDK base image with Java 8 and Java 11 is now obsolete and has been transferrred to the „Adoptium Eclipse Temurin“ project. Nevertheless, both docker repositories are provided by the same upstream GitHub repository. Instead, they are published under csanchez/maven. These Java variants are not published directly under the official maven Docker repository. The following list gives an overview of the Java images I identified and the results according to the above criteria: Name ![]() ![]() That’s why I would be happy to have an official Maven image to build the application inside a CI pipeline with the same Java as in my base image.
