How to build and deploy a web project using BitBucket + Ubuntu Shell Script


  • In General, we deployed a web project using Jenkins or Pipelines (BitBucket) or many DevOps other tools but what we could do when we have a limited budget or resource for server-side. Is another way to build and deploy your web project automatically with a schedule? I will say, yes it is possible to do that. So let’s try to understand a process.
Step1:
  • Here I will use Ubuntu Shell Script with a cronjob, Spring Boot (Hello! World), bitbucket, and AWS E2 Instance where we will deploy a web application.
  • Here I created one Spring boot HelloWorld.
  • As you can see above the screen-shot, I created a package `com.spring_boot.controller.HelloWorldController` and rest controller inside it.






  • And commit and push code in a bitbucket repository.
Step 2:
  •  let’s connect to AWS EC2 instance Ubuntu and install requirement SDK like Open JDK 8, Maven, and Apache Tomcat 8.
  • If you didn't install SDK tools then you can follow the below commands for ubuntu.
    • sudo add-apt-repository ppa:openjdk-r/pp
    • sudo apt-get update
    • sudo apt-get install openjdk-8-jdk
    • sudo apt-get install maven

Step 3:
  • Now I will configure `SSH` keys in the AWS EC2 instance by following Bitbucket Documentation
(https://confluence.atlassian.com/x/X4FmKw).

Step 4:
  • Once you configured `SSH` Keys with AWS EC2 Ubuntu instance and Bitbucket.
  • Create a folder for a project and take the clone of the project in AWS EC2 Ubuntu instance.
  • Now I will take the clone using `SSH` as you can see below the screenshot.











      • mkdir your_source_dir_name
      • cd your_source_dir_name
      • git clone bitbucket_url


      Step 5:  
      • Now let's create an Ubuntu Shell Script which builds and deploys your code in tomcat
        • Here I used the `VI` editor of Ubuntu, follow the below command to create a shell script
        • vi .sh,  if you don't know about `VI` then you can easily find out from google or any search engine or any other tutorial.  
        • To run your shell script type: sh ./<your_script_name>.sh
        • Build commands are given below:
              
 #!/bin/bash

# First Go to your tomcat dir and shutdown your tomcat
cd /opt/tomcat/apache-tomcat-8.5.47/bin/
sh ./shutdown.sh
sleep 5

# Now, Move your project dir  
cd /opt/spring_hello_world/spring_boot_hello_world/
sleep 5

# Take a pull of current branch
git pull origin master
sleep 5

# Make a war of Project 
mvn clean compile package
sleep 5

# Now copy a war file to tomcat webapp dir 
cp -i /opt/spring_hello_world/spring_boot_hello_world/target/spring_hello_world.war /opt/tomcat/apache-tomcat-8.5.47/webapps/
sleep 5

# remove target folder after copy war
rm -r target/
sleep 5

# Finally Start Your Tomcat and check out log file
cd /opt/tomcat/apache-tomcat-8.5.47/bin/
sh ./startup.sh



       

      Step 6: Now Let's add some changes in `HelloController` and push that into a server.




      Step 7: once you pushed your code build your shell script again by the following a command sh ./<your_script_name>.sh



      So as you can see a new change from the above screenshot. You can also try the way in which I followed.

      Thanks
