my new own file #7
Conversation
WalkthroughThe changes introduced involve a modification to a repository URL in a shell script for cloning a Django application and the creation of a new shell script that automates the provisioning of an EC2 instance on AWS. The new script includes functions for checking and installing the AWS CLI, as well as creating and monitoring the status of the EC2 instance. Changes

5-10: LGTM!The function is correctly implemented and handles the absence of AWS CLI gracefully.
The code changes are approved.
12-26: LGTM! But verifysudoavailability.The function is correctly implemented. However, it assumes that
sudois available and the user has the necessary permissions.Consider adding a check for
sudoavailability or documenting this requirement.

Add a timeout mechanism.
The function is correctly implemented. However, it lacks a timeout mechanism to avoid infinite loops.
Consider adding a timeout mechanism to avoid infinite loops. For example:
wait_for_instance() {
local instance_id="$1"
+ local timeout=300 # 5 minutes
+ local start_time=$(date +%s)
echo "Waiting for instance $instance_id to be in running state..."
while true; do
state=$(aws ec2 describe-instances --instance-ids "$instance_id" --query 'Reservations[0].Instances[0].State.Name' --output text)
if [[ "$state" == "running" ]]; then
echo "Instance $instance_id is now running."
break
fi
+ if [[ $(($(date +%s) - start_time)) -ge $timeout ]]; then
+ echo "Timeout waiting for instance $instance_id to be in running state." >&2
+ return 1
+ fi
sleep 10
done

Remove redundant check for AWS CLI installation.
The function is correctly implemented. However, there is a redundant check for AWS CLI installation.
Consider removing the redundant check for AWS CLI installation. Apply this diff:
main() {
check_awscli || install_awscli
- if ! check_awscli ; then
- install aws_cli || exit 1
- fi
echo "Creating EC2 instance..."
# Specify the parameters for creating the EC2 instance

Add input validation for parameters.
The function is correctly implemented. However, it lacks input validation for the parameters.
Consider adding input validation for the parameters to ensure they are not empty. For example:
create_ec2_instance() {
local ami_id="$1"
local instance_type="$2"
local key_name="$3"
local subnet_id="$4"
local security_group_ids="$5"
local instance_name="$6"
+ if [[ -z "$ami_id" || -z "$instance_type" || -z "$key_name" || -z "$subnet_id" || -z "$security_group_ids" || -z "$instance_name" ]]; then
+ echo "One or more required parameters are missing." >&2
+ return 1
+ fi
