Docker

  1. Create folders booksBackEnd and booksFrontEnd in root of git repo folder.
  2. In booksBackEnd we put .jar and create app.Dockerfile
  3. Contents of app.Dockerfile:
# Use a Java 21 base image
FROM openjdk:21-jdk-slim

# Maintainer information
LABEL maintainer="isaacdiez"

# Copy the application JAR file to the container
COPY BooksPageable-0.0.4-SNAPSHOT.jar books.jar

# Set the entry point to run the JAR file
ENTRYPOINT ["java", "-jar", "books.jar"]

  1. In folder booksFrontEnd we create yet another folder named frontend where we put all the uncompressed contents of the react project.

  2. We create frontend.Dockerfile:

FROM nginx:alpine
COPY frontend/ /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
  1. In CLI:
sudo docker build -f app.dockerfile -t books .
sudo docker run -p 8080:8080 books
sudo docker build -t frontend-pra04 -f frontend.Dockerfile .
sudo docker run -d -p 90:80 frontend-pra04
