Attendance WebApp

Introduction

Attendance WebApp is a proof of concept to improve the way attendance is managed at AUT university.

The application uses maven, J2EE, primefaces, gson.

    maven {
         url = uri("https://repository.primefaces.org")
    }

The idea is that you have a short timeframe to submit a random generated code by the lecturer so that attendance can be registered in the system.

The application is a proof of concept for Service orientation and Service interoperability in the cloud

GitHub Vulnerability report

https://github.com/aleon1220/multi-cloud-WebApp-Attendance/security/dependabot

Attendance WebApp Architecture (re-architected)

2018 project with a lot of things to change

• Simplification of used services
• Streamline app to use 100% rest and deprecate SOAP and WSDL
• Create a simple test OpenLDAP instance for users and roles
• Host the WebApp in Azure
• Host the backend functionality in AWS
• use diagrams.net for the diagrams

Attendance WebApp UI

Refer to the Wiki for details on the project

Detailed Project Wiki

Quickstart

• Gradle Build Web Package build and test the WebArchive file. Generates the .WAR file in build/libs/*.war

gradle clean build --console plain --warning-mode all

• Gradle Check the generated version from the build.gradle.kts

gradle getAppversion

• Run WebApp Run the tomcat server with the latest pre-built WAR web Archive file Run from Docker Hub

docker run -itd --publish 8080:8080 --name attendance_webapp_container aleon1220/soa:latest

Local Setup

Tested in Win11 with WSL, Github codespaces and Linux Ubuntu 22

Project general guidelines

1. Installation process: project a Java project JEE. Import in any IDE and build with gradle or maven. Build docker image and run
2. Software dependencies: dependencies are described in pom.xml file
3. Latest releases by using git tags
4. API references. API docs

• Clone repo HTTPS

git clone https://github.com/aleon1220/multi-cloud-WebApp-Attendance.git

• Clone Repo SSH

git clone git@github.com:aleon1220/multi-cloud-WebApp-Attendance.git

• open repo in chosen IDE IDEs can be Eclipse, IntelliJ (suggested) or use online IDE (Github codespaces)

Maven Build

maven has been deprecated and moved to maven

Perform local testing

Gradle Test suite

Use 1Password CLI to inject the secrets

• as a pre-requisite you must have access to the shared vault
• login in the CLI

# Linux Ubuntu tested 2023-12-10
op signin

• inject the secrets for testing Authentication property file

op inject -i token_auth.properties.tpl -o token_auth.properties

• inject the secrets for Testing property file

op inject -i secrets.env.tpl -o secrets.env

• inject the secrets for Testing docker-compose

op inject -i .env.tpl -o .env

Execute the Gradle commands

Should do validations

gradle check --warning-mode all

Set the variables

Docker Image Build

• Build the app image with Docker. Deploy .WAR file in Tomcat refer to https://hub.docker.com/_/tomcat

docker build --build-arg APP_WAR_FILE_VERSION=$APP_WAR_FILE_VERSION --tag aleon1220/soa:$APP_WAR_FILE_VERSION .

Available Tomcat versions

if you need to edit the Dockerfile and upgrade the servlet container Tomcat version

• 7.0.109 = TOMCAT_VERSION_DOCKER_TAG="7.0.109-jdk8-openjdk"
• 9.0.78 = TOMCAT_VERSION_DOCKER_TAG="9.0.78-jre8"

for particular versions check the image in Docker hub

Execute WebApp Container Execution

Docker execution by image version

Test the immutable webapp from Docker

docker run -itd --publish 8080:8080 aleon1220/soa:$APP_WAR_FILE_VERSION

local development & executions

Test the container webapp after building the image locally

docker run -itd --publish 8080:8080 --name attendance_webapp_container aleon1220/soa:$APP_WAR_FILE_VERSION

• Get the name of the running container

CONTAINER_NAME=$(docker container ls --all --filter publish=8080 --format "{{.Names}}")

• The URl is hostname:8080/$CONTEXT
• Get the context of the webapp

TOMCAT_URL="http://$(hostname):8080/Attendance-$APP_WAR_FILE_VERSION"

• Access the Docker container via CLI

docker container exec -it $CONTAINER_NAME /bin/bash

• clean up docker container environment

docker stop $(docker ps --quiet)
docker rm $(docker container ls --all --quiet)

Docker-compose

• inject the secrets for Testing docker-compose

op inject -i .env.tpl -o .env

• single variable

export LDAP_ADMIN_PASS=$(op read "op://uqbpxejq7gifvi6mg3c7xxokre/jvuj7juvlxlg7delckucvidqhi/password")

Editing project diagrams

• go to diagrams.net
• open the file project-diagrams.drawio XML file with the diagrams
• Explore > export images to convinience and update this README
