Overview

This project contains Dockerfiles that allow developers to easily create Docker images containing combinations of:

• Maven: To manage project dependencies and build Java applications.
• JDK (Java Development Kit): To compile and run Java programs.
• Node.js: To run JavaScript code and develop Node.js applications.
• NPM: To manage Node.js dependencies.
• Yarn: To manage Node.js dependencies.

Each Dockerfile is tailored for a specific combination of Maven, JDK, and Node.js versions, providing flexibility to select the ideal environment for different use cases.

Available Dockerfile Versions

The following combinations are provided in this repository:

Dockerfile Name	Maven Version	JDK Version	Node.js Version
Dockerfile.maven3.6.3-eclipse-temurin8-node14	3.6.3	8	16
Dockerfile.maven3.8.7-eclipse-temurin11-node16	3.8.7	11	16
Dockerfile.maven3.8.7-eclipse-temurin11-node18	3.8.7	11	18
Dockerfile.maven3.9.9-eclipse-temurin17-node20	3.9.9	17	20

Each combination is defined in its own Dockerfile, allowing users to choose the appropriate setup for their project.

Project Structure

The repository follows a structured format where each combination of versions has its own Dockerfile in the dockerfiles/ directory.

Dockerfile Example

# Dockerfile.maven3.9.9-eclipse-temurin17-node20
FROM eclipse-temurin:17-jdk

# Install Maven
ENV MAVEN_VERSION=3.9.9
RUN apt-get update && \
    apt-get install -y wget tar && \
    wget https://archive.apache.org/dist/maven/maven-3/${MAVEN_VERSION}/binaries/apache-maven-${MAVEN_VERSION}-bin.tar.gz && \
    tar xzvf apache-maven-${MAVEN_VERSION}-bin.tar.gz -C /opt && \
    ln -s /opt/apache-maven-${MAVEN_VERSION}/bin/mvn /usr/bin/mvn

# Install Node.js
ENV NODE_VERSION=20
RUN apt-get install -y curl && \
    curl -fsSL https://deb.nodesource.com/setup_${NODE_VERSION}.x | bash - && \
    apt-get install -y nodejs

# Set environment variables
ENV MAVEN_HOME=/opt/apache-maven-${MAVEN_VERSION}
ENV PATH=$MAVEN_HOME/bin:$PATH

# Verify installations
RUN java -version && mvn -version && node -v && npm -v

CMD ["/bin/bash"]

Docker Build Instructions

To build an image from a specific Dockerfile, navigate to the root directory and run:

docker build -t <image-name> -f dockerfiles/Dockerfile.<version-combination> .

For example, to build an image containing Maven 3.9.9, JDK Eclipse Temurin 17, and Node.js 20:

docker build -t maven-jdk-node:maven3.9.9-eclipse-temurin17-node20 -f dockerfiles/Dockerfile.maven3.9.9-eclipse-temurin17-node20 .

How to Use

Once the image is built, you can use it in your development environment or CI/CD pipelines.

Running the Image

To run the image interactively:

docker run -it <image-name> /bin/bash

For example:

docker run -it maven-jdk-node:maven3.9.9-eclipse-temurin17-node20 /bin/bash

Integrating with CI/CD Pipelines

You can integrate these Docker images into your CI/CD pipeline by specifying the appropriate image tag in your pipeline configuration.

For example, in GitLab CI:

image: maven-jdk-node:maven3.9.9-eclipse-temurin17-node20

Customization

You can modify the Dockerfiles to use different versions of Maven, JDK, or Node.js by updating the relevant lines in each Dockerfile.

For example, to change the JDK version:

FROM eclipse-temurin:11-jdk

You can also install additional dependencies or make other customizations as needed.
