 Practicle 9 : AWS SAM CLI Setup & Hello World Deployment

Objective: To install AWS SAM CLI, create a sample serverless application, and run it locally using Docker.

Steps to Follow

Step 1: Open the terminal and update your system using the command: sudo apt-get update && sudo apt-get upgrade.

Step 2: Download the AWS CLI v2 zip file using: curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip".

Step 3: Download the signature file for AWS CLI with the command: curl -o awscliv2.sig https://awacli.amazonaws.com/awscli-exe-linux-x86_64.zip.sig.

Step 4: Unzip the downloaded file using the command: unzip awscliv2.zip.

Step 5: Install AWS CLI by running: sudo ./aws/install.

Step 6: Now install the AWS SAM CLI using: pip3 install aws-sam-cli.

Step 7: Type sam init in the terminal to launch the SAM setup. When prompted, select the first option to use AWS Quick Start Templates.

Step 8: Choose Template No. 1, which is the "Hello World Example".

Step 9: If prompted to use the most popular runtime and package type, type "N". Now, open a new terminal by pressing Ctrl + Shift + T and check your Python version by typing python --version.

Step 10: When asked for the package type, choose "zip".

Step 11: Continue by selecting "Yes" whenever prompted and give your project a name. For example, you can name it "sam-app-test".

Step 12: After project setup, a folder with your project name will be created. Navigate into that folder using the cd command followed by your folder name. Once inside, invoke the HelloWorldFunction using the command sam local invoke "HelloWorldFunction". You should receive a response with StatusCode: 200. If you encounter a Docker error, install Docker using the command sudo snap install docker.

Step 13: Start the local API by typing sam local start-api. This will generate a localhost URL. Open the given URL in any browser to test your local serverless application.

Practical 10: Implementation of openstack with user and private network creation

Step 1: Update and Reboot the System

Log into your Ubuntu 18.04 system using SSH. Once logged in, 

update and upgrade your system repositories by running the following command:

apt update -y && apt upgrade -y. 

After the update process is complete, reboot the system by running: sudo reboot.

Step 2: Create a 'stack' User and Assign Sudo Privileges

To follow best practices, DevStack should be run by a non-root user with sudo privileges. 

Create a new user named stack by running: sudo adduser --shell /bin/bash --home /opt/stack --gecos "" stack. 

Then, grant this user sudo privileges by executing the following command: echo "stack ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/stack.

Step 3: Install Git and Download DevStack

After creating the user stack, switch to this user by running su - stack. 

Now, ensure git is installed. If not, install it by running: sudo apt install git -y. 

Once git is installed, clone the DevStack repository from the OpenStack official Git source using the command: git clone https://opendev.org/openstack/devstack.

Step 4: Create the DevStack Configuration File

Navigate to the DevStack directory by running: cd devstack.

 Create a configuration file named local.conf by running: vim local.conf. 

Paste the following content into the file, replacing 10.208.0.10 with your actual server IP address (which you can find by running ip addr or ifconfig):


[[local|localrc]]

# Passwords for KeyStone, Database, RabbitMQ, and Services
ADMIN_PASSWORD=StringAdminSecret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

# IP address of your server (get it using 'ip a')
HOST_IP=10.208.0.10

Once the file is created, save and exit the text editor.

Step 5: Install OpenStack with DevStack

To begin the installation process,

 run the following script inside the DevStack directory: ./stack.sh. 

This will install various OpenStack components,

 including Horizon (Dashboard), Nova (Compute service), Glance (Image service), Neutron (Network service), Keystone (Identity service), Cinder (Block storage service), and the Placement API. The installation will take about 10 to 15 minutes depending on the speed of your system and internet connection.

Step 6: Access OpenStack via a Web Browser

Once the installation is complete, OpenStack should be accessible via a web browser. Open your browser and go to: http://<your-server-ip>/dashboard (e.g., http://10.208.0.10/dashboard). 

This will bring up the OpenStack login page. 

Log in using the username admin and the password you set in the local.conf file (e.g., StringAdminSecret).

 After logging in, you will be taken to the OpenStack management console dashboard.
