AWS Boto3 Scripts

Setup

Make sure your ~/.aws/config and ~/.aws/credentials files are configured correctly.

First setup a virtual environment (recommended) :

python3 -m venv venv
source venv/bin/activate

and install dependencies :

pip install -r requirements.txt

Usage

You can then use the scripts like this :

Instance Launcher

Launches an instance by providing:

• AMI ID
• Instance type
• Subnet ID
• If it should have a public IP assigned (yes/no)
• Security group name
• Key name

Returns the new instance ID and its state

python3 instance_launcher.py "<image_id> <instance_type> <subnet_id> <has_public_ip> <security_group_name> <key_name>"

Example:

python3 instance_launcher.py ami-096ccd3d4d0561c2e t2.micro subnet-06f709f8bc1cb17f6 yes http-ssh-sg CEU-Keys

List instances

Lists all the following info about your non-terminated instances in your default region :

• Instance ID
• State name
• Image (AMI) ID
• Subnet ID
• Key name
• Security group(s) name(s)
• Private IP address
• Public IP address (only if it has one)

python3 list-instances.py

List subnets

Lists all the following info about the subnets in your default region

• Subnet ID
• VPC ID
• CIDR Block
• If it automatically assigns a Public IP when launching an instance inside the subnet (yes/no)

python3 list-subnets.py

Ressource counter

Lists the number of following ressources created in your account

• Volumes
• Snapshots
• Security Groups
• Load balancers
• Key Pairs

python3 ressource-counter.py

Instance Killer

Terminates the specified instance(s) (by providing its/their instance ID('s))

python3 instance_killer.py <instance1_id> <instance2_id> <instance3_id>...

Example:

python3 instance-killer.py i-0c429c8738e9dc459

Instance Tagger

Assigns a tag to a specific instance (by providing its instance ID)

Returns the instance AMI ID and all its associated tags

python3 instance_tagger.py <instance_id> <tag_key> <tag_value>

Example:

python3 instance_tagger.py i-0c429c8738e9dc459 MyTagKey MyTagValue

Instance Relauncher (by tag)

Finds all stopped instances (= 'stopped' state name), and if it has the specified Tag Key it launches the instance again (= 'running' state name)

python3 instance-relauncher-by-tag.py <tag_key>

Example:

python3 instance-relauncher-by-tag.py MyTagKey
