aws-intel

aws-intel is a command-line tool for retrieving useful information from AWS.

The project is in its initial development stage.

Requirements

• Python 3.10 or newer
• Poetry

Development

Install the project and its development dependencies:

poetry install

Run the CLI:

poetry run awsi --help

Commands follow this structure:

awsi <utility> <options>

List all available utilities and their descriptions, or show detailed help for one utility:

awsi help
awsi help security-group-tree
awsi help forward

For example:

awsi security-group-tree sg-0123456789abcdef0

security-group-tree recursively displays security groups, their attached resources, IPv4 and IPv6 ranges, and managed prefix lists connected through inbound and outbound rules. Each connection is prefixed with its protocol and port or port range and its direction, such as tcp 443 from 10.0.0.0/8 for an inbound rule or udp 1000-2000 to 10.0.0.0/8 for an outbound rule. Attached resources are grouped under Assigned to, inbound connections under Sources, and outbound connections under Targets. Resource discovery includes AWS-managed network interfaces. Resource Name tags are displayed when available, with existing descriptions or IDs used as fallbacks. This requires permission to call ec2:DescribeNetworkInterfaces and ec2:DescribeTags. Referenced security groups are displayed as sg-0123456789abcdef0 (name) so the rule's actual source or target identifier appears before its descriptive name.

For RFC 1918 IPv4 ranges, the command also lists network interfaces in the security group's VPC whose primary or secondary private address is within the range. Each match includes its concrete private IP address. Public IPv4 and IPv6 ranges are not resolved, and resources in other accounts, Regions, peered VPCs, transit networks, or on-premises networks are outside the lookup scope.

The command uses the active AWS CLI credentials and region. Limit output to one direction with --inbound or --outbound; the flags are mutually exclusive. Filter the displayed tree with --filter TEXT. Matching is case-insensitive; matching nodes retain their descendants, and ancestor paths are retained for context. The Assigned to metadata for security groups on a matching path is also retained. For example, --filter acc finds labels containing ACC. Control recursive security-group expansion with --depth DEPTH. The default depth is 1, which shows resources and rules inside the starting security group without expanding the contents of referenced groups. The maximum is 3 because each expanded group and private network can require additional AWS API calls, and the number of referenced groups can grow rapidly at each level. Interactive terminals show a loading indicator while AWS resources are being retrieved. The indicator is written to standard error and is disabled when output is redirected or piped.

Start an SSM port forwarding session through an online, SSM-managed EC2 instance to a host reachable from that instance:

awsi forward start primary-database \
  --instance-id=i-0123456789abcdef0 \
  --host=db.internal --port=5432:5432

The bastion can also be selected by its exact EC2 Name tag, which remains stable when an instance is replaced:

awsi forward start database --instance-name=public-bastion \
  --host=db.internal --port=5432:5432

Only active (pending or running) instances are considered. The command fails rather than choosing arbitrarily if multiple active instances have the same Name tag. --instance-id and --instance-name are mutually exclusive.

The first port is the local listening port and the second is the remote host's port. The command uses the AWS-StartPortForwardingSessionToRemoteHost document and starts the session in the background, then prints a confirmation containing the process ID. The AWS CLI and its Session Manager plugin must be installed.

Save a named forward without resolving the instance or starting a session:

awsi forward save apigateway-dev \
  --instance-name=solo-connect-bastion-dev \
  --host=internal-apigw-internal-dev-2025348469.eu-west-1.elb.amazonaws.com \
  --port=9072:9072

The save action adds or replaces that name in .awsi/forwards.yaml under the current working directory without resolving the instance or starting a session. The generated configuration looks like this:

forwards:
  apigateway-dev:
    instance-name: solo-connect-bastion-dev
    host: internal-apigw-internal-dev-2025348469.eu-west-1.elb.amazonaws.com
    port: 9072:9072

Start a saved forward by its configuration name:

awsi forward start apigateway-dev

The command reads .awsi/forwards.yaml from the current working directory, resolves the configured instance when necessary, and starts the forward using the saved host and port mapping.

List all saved definitions with:

awsi forward configs

List forwards started by awsi that still have a running process with:

awsi forward active

The output has a tab-separated header and columns for process ID, optional name (- when unnamed), bastion instance ID, remote host, and the port mapping. Completed forwards are removed from the list:

PID	NAME	INSTANCE_ID	HOST	PORT
4321	primary-database	i-0123456789abcdef0	db.internal	5432:5432

End an active forward by its exact name:

awsi forward stop primary-database

If no forward has that name, the reference is interpreted as a process ID:

awsi forward stop 40234

Only forwards tracked by awsi can be terminated. When multiple active forwards share a name, use the process ID shown by --list. List online SSM-managed EC2 instances in the active account and region with:

awsi forward hosts

The list is tab-separated: instance ID followed by the EC2 Name tag when one is present. Listing requires ssm:DescribeInstanceInformation and ec2:DescribeInstances; starting a session requires the corresponding ssm:StartSession and session-channel permissions.

awsi forward NAME, awsi forward list, awsi forward --list, awsi forward --kill, and awsi forward --list-hosts remain available as compatibility aliases, but the action-based forms above are the recommended interface. Forward names are positional; the former --name option is no longer supported.

Supply multiple security group IDs to combine them as sibling roots in one tree:

awsi security-group-tree sg-0123456789abcdef0 sg-11111111111111111

Run the tests:

poetry run pytest

Build distribution artifacts:

poetry build

Continuous integration and releases

Pull requests and pushes to main run the test suite on the oldest and newest supported Python versions. After the tests pass, CI builds the wheel and source distribution and stores them as workflow artifacts.

Releases use the Publish to PyPI workflow:

1. In the repository's Actions tab, select Publish to PyPI and choose Run workflow from the main branch.
2. Choose patch, minor, or major for the semantic version increment.
3. Approve the pypi environment deployment when prompted.

Before the first release:

• Add the appropriate project authors and license metadata to pyproject.toml and confirm that the aws-intel name is available on PyPI.
• Create a GitHub Environment named pypi and add the required reviewers whose approval is needed to publish.
• Configure a PyPI trusted publisher for this repository, the publish.yml workflow, and the pypi environment. No PyPI API token is required.
• Ensure repository rules allow GitHub Actions to push the release version commit to main.

After approval, the workflow reruns the tests, increments the version in pyproject.toml, builds the distributions, pushes the version commit to main, and publishes through PyPI trusted publishing. Only one release workflow can run at a time.
