Mastering AWS CLI: How to Start EC2 Instances on Ubuntu Like a Pro.

To start EC2 instances using the AWS CLI on Ubuntu, follow these steps:

1. Install the AWS CLI on your Ubuntu system, if it’s not already installed. You can use the following command to install it:

sudo apt-get update
sudo apt-get install awscli

2. Configure the AWS CLI by running the following command:

aws configure

You’ll be prompted to enter your AWS access key ID, secret access key, default region name, and output format.

3. Once the CLI is configured, you can use the following command to start your EC2 instances:

aws ec2 start-instances --instance-ids instance_id

Replace “instance_id” with the actual ID of the EC2 instance you want to start. If you want to start multiple instances at once, you can specify their IDs separated by spaces.

For example, to start an instance with the ID “i-0123456789abcdef0”, you would use the following command:

aws ec2 start-instances --instance-ids i-0123456789abcdef0

If successful, the command will output a JSON object containing information about the started instances.
