1. Manualy Build, Test, and Deploy By Maven

1.1 Start Nexus (Optional)

$ cd ~/sonatype/nexus/bin
$ ./nexus start

Visit http://localhost:8081/ with admin/admin123.

1.2 Build

$ mvn clean package -Dmaven.test.skip=true  
...

Explain: -DskipTests, not execute test case, but compile test case; -Dmaven.test.skip=true，not compile test case, neither execute test case.

Attention: Due to China GFW, you may fail when you build this project. Try it outside China GFW.

1.3 Run Locally

$ mvn jetty:run
[INFO] Scanning elapsed time=147ms
[INFO] DefaultSessionIdManager workerName=node0
[INFO] No SessionScavenger set, using defaults
[INFO] node0 Scavenging every 660000ms

[INFO] Started @3779ms
[INFO] Started Jetty Server

By default, the jetty port is 9999, so you should visit following urls in browser:

To run in a different port, mvn jetty:run -Djetty.port=<Your-Port>.

To debug locally, set MAVEN_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n, then mvn jetty:run.

To stop Jetty Server, press Control-C.

1.8 Start Jmeter GUI (Optional)

If you want to see the test plan, you need install Jmeter, then start Jmeter GUI and open java-maven-calculator-web-app/src/test/jmeter/CalculatorTestPlan.jmx.

$ cd ~/apache/jmeter/bin
$ ./jmeter

Don't use GUI mode for load testing !, only for Test creation and Test debugging.For load testing, use CLI Mode:

$ cd ~/apache/jmeter/bin
$ ./jmeter.sh -n -t ~/code/java-maven-calculator-web-app/src/test/jmeter/CalculatorTestPlan.jmx -Jusers=20 -Jloop=2 -l ~/code/java-maven-calculator-web-app/src/test/jmeter/calculator_`date +'%y%m%d%H%M%S'`.csv

Project name: MyJavaMavenCalculateWebApp-AzureAppService-FTP

2.4 Create and Configure a Freestyle Jenkins Project, using Azure App Service plugin

Project name: MyJavaMavenCalculateWebApp-AzureAppService

3. Containerize Your Web App

3.1. Build a docker image using Dockerfile:

$ docker build -t calculator .
Sending build context to Docker daemon  13.53MB
Step 1/4 : FROM tomcat
 ---> 48dd385504b1
Step 2/4 : MAINTAINER Ma Ping
 ---> Using cache
 ---> 3ae09eb166a2
Step 3/4 : RUN rm -rf $CATALINA_HOME/webapps/ROOT
 ---> Using cache
 ---> 20a183105b0e
Step 4/4 : COPY target/calculator.war $CATALINA_HOME/webapps/ROOT.war
 ---> 42b9363d582d
Successfully built 42b9363d582d
Successfully tagged calculator:latest

3.2. Run docker image locally

$ docker run --rm -p 8181:8080 calculator

Explain: --rm means delete the container after stopping it.

Access the web app at http://localhost:8181/api/calculator/ping in browser.

Press Control-C to stop and remove the container.

3.3. Push your local image to your docker hub repositories

$ docker login -u <Your-Docker-ID> -p <Your-Docker-Password>
$ docker tag calculator <Your-Docker-ID>/calculator
$ docker push <Your-Docker-ID>/calculator

4. Deploy to Azure Web App using Container Image in Docker Hub

  1. Create a Web App in Linux on Azure
  2. Save the changes and you'll be able to access the web app in a few seconds.

5. Deploy to Your Azure Web App using Container Image in ACR

  1. Create a Container Registry on Azure
  2. Push your local image to ACR:
$ docker login <Your-ACR-Login-Server> -u <Your-ACR-Username> -p <Your-ACR-Password>
$ docker tag calculator <Your-ACR-Login-Server>/calculator
$ docker push <Your-ACR-Login-Server>/calculator
  1. Create a Web App in Linux on Azure
  2. In Docker Container settings of Web App, fill in image name, server URL, username and password of your ACR.
