Aws

First I set up the environment for Elastic Beanstalk to deploy the application called "Choose your Player". Created an Amazon Linux EC2 instance called Jenkinss. After I finished setting it up in terms of the attributes and different specifications (storage, security group, tag, etc) I used the given public ip within my terminal along with my ssh key to ssh into instance.

Terminal

Using my terminal I input these following commands:

$ sudo yum update -y

$ sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

$ sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

$ sudo yum upgrade

$ sudo yum install jenkins java-1.8.0-openjdk-devel -y

$ sudo amazon-linux-extras install epel

$ sudo systemctl daemon-reload

$ sudo systemctl start jenkins

$ sudo cat /var/lib/jenkins/secrets/initialAdminPassword

Jenkins

Added 2 plugins before starting

1. AWSEB Deployment Plugin
2. Cloudbees Deployment Plugin

Created a freestyle project Then within my freestyle project and under source management selected git added my github url containing the custom app respository Next I added my elastic beanstalk infomation and under the root object a . was included as well. Following that the version label format was added to the build version as python-01${BUILD_ID}

Front-end

In the application file it was important to set application = app = Flask(name) to ensure that Jenkins doesnt disrupt the application.

Then the function render_template was used to call the information in the front.html file.

In order for the code to be deployed without any errors application.run was called within the app.py file.

The layout.css file was utilized to set the background.

The front.html file was utilized to format the webpage within the code it is encoded to take the response from the user and respond back with the computers choice and spit back the winner or loser.

Issues

Terminal issues

With in the terminal the first issue I ran into was when using ssh to connect to my instance after typing in a few commands once I got to this command: sudo yum install jenkins java-1.8.0-openjdk-devel -y I received this error Error: Package: jenkins-2.303.1-1.1.noarch (jenkins) Requires: daemonize To fix this error I had to use this command Solution:sudo amazon-linux-extras install epel

Jenkins issues

• Elastic Beanstalk kept coming up as degraded Solution: Changing app.py to application.py as well as requirement.py to requirements.py

I chose to do this application because it was a great debate. Everyday in terms of twitter,barbershops,parks,households this conversation comes up. I am a big fan of all 3 players. Basketball is a topic that creates great debate and is very polarizing and I wanted to create something that added to that discussion. In terms of python a great way to practice if statements.

Unfortunately, I was unable to deploy this app. Until, I removed app.run() at the end of my code , removing this line of code allowed my environment to be shown in the environment of my elastic beanstalk. The reason it didnt work was app.run when its goes through jenkins causes an error when its being read in jenkins which causes it not to apart in the elastic beanstalk.
