Using Docker

# Run interactively
docker run --rm -it ghcr.io/huseyinbabal/taws

# Launch with a specific profile (mount AWS credentials)
docker run --rm -it \
  -v ~/.aws:/root/.aws:ro \
  ghcr.io/huseyinbabal/taws --profile production

# Launch in a specific region
docker run --rm -it \
  -v ~/.aws:/root/.aws:ro \
  ghcr.io/huseyinbabal/taws --region us-west-2

# Using environment variables
docker run --rm -it \
  -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
  -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
  -e AWS_REGION=us-east-1 \
  ghcr.io/huseyinbabal/taws

# Build locally
docker build -t taws .
docker run --rm -it -v ~/.aws:/root/.aws:ro taws

Note: Use -it flags for interactive terminal support (required for TUI). Mount your ~/.aws directory as read-only to use your existing AWS credentials.

From Source

Prerequisites

  • AWS Credentials - See Authentication section below
  • IAM Permissions - Your AWS user/role needs appropriate read permissions for the services you want to browse. At minimum, you'll need Describe* and List* permissions.

Authentication

taws uses a credential chain, trying each source in order:

Priority Source Description
1 Environment Variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN
2 AWS SSO If profile has SSO configured, uses SSO (prompts for login if needed)
3 Role Assumption If profile has role_arn + source_profile, assumes the role
4 Credentials File ~/.aws/credentials
5 Config File ~/.aws/config
6 IMDSv2 EC2 instance metadata

AWS SSO

taws supports AWS SSO. If your profile uses SSO and the token is expired, taws will prompt you to authenticate via browser.

Both SSO config formats are supported:

  • Modern: sso_session reference to [sso-session X] section
  • Legacy: sso_start_url directly in profile

If you already logged in via aws sso login, taws will use the cached token automatically.

IAM Role Assumption

taws supports assuming IAM roles using role_arn with either source_profile or credential_source. This is commonly used for:

  • Cross-account access (e.g., dev account assuming role in prod account)
  • Least-privilege access patterns
  • Chained role assumption
  • Container-based deployments (ECS, Lambda)

Using source_profile

Reference another named profile for source credentials:

[profile base]
region = us-east-1

[profile production]
role_arn = arn:aws:iam::123456789012:role/ProductionAccess
source_profile = base
region = us-west-2

# Optional: external_id for cross-account trust
[profile partner-account]
role_arn = arn:aws:iam::987654321098:role/PartnerAccess
source_profile = base
external_id = my-external-id

Using credential_source

Load source credentials from environment, EC2 metadata, or ECS container:

# For ECS tasks with task IAM roles
[profile ecs-admin]
role_arn = arn:aws:iam::123456789012:role/AdminRole
credential_source = EcsContainer

# For EC2 instances with instance roles
[profile ec2-admin]
role_arn = arn:aws:iam::123456789012:role/AdminRole
credential_source = Ec2InstanceMetadata

# For environments with AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY set
[profile env-admin]
role_arn = arn:aws:iam::123456789012:role/AdminRole
credential_source = Environment

Supported credential_source values:

Value Description
Environment Load from AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN
Ec2InstanceMetadata Load from EC2 instance metadata (IMDSv2)
EcsContainer Load from ECS container credentials endpoint

Supported options:

Option Required Description
role_arn Yes ARN of the IAM role to assume
source_profile One of Profile to use for source credentials
credential_source these Where to load source credentials from
external_id No External ID for cross-account trust policies
role_session_name No Custom session name (default: taws-session)
duration_seconds No Session duration in seconds (default: 3600)
region No Region for STS endpoint

Notes:

  • Use exactly one of source_profile OR credential_source (not both)
  • Chained role assumption is supported (source_profile can also use role_arn)
  • Temporary credentials are cached and automatically refreshed before expiration
  • ECS container credentials require AWS_CONTAINER_CREDENTIALS_RELATIVE_URI or AWS_CONTAINER_CREDENTIALS_FULL_URI environment variables (set automatically by ECS)

Quick Start

# Launch taws with default profile
taws

# Launch with a specific profile
taws --profile production

# Launch in a specific region
taws --region us-west-2

# Enable debug logging
taws --log-level debug

# Run in read-only mode (blocks all write operations)
taws --readonly

# Use with LocalStack or custom endpoint
taws --endpoint-url http://localhost:4566

# Or via environment variable
AWS_ENDPOINT_URL=http://localhost:4566 taws

Log File Locations

Platform Path
Linux ~/.config/taws/taws.log
macOS ~/Library/Application Support/taws/taws.log
Windows %APPDATA%\taws\taws.log

Shell Completion

taws supports shell completion for bash, zsh, fish, and PowerShell.

# Bash (add to ~/.bashrc)
eval "$(taws completion bash)"

# Zsh (add to ~/.zshrc)
eval "$(taws completion zsh)"

# Fish (add to ~/.config/fish/config.fish)
taws completion fish | source

# PowerShell (add to $PROFILE)
taws completion powershell | Out-String | Invoke-Expression

After adding the completion script, restart your shell or source the config file.

Configuration

See Authentication for credential setup.

Environment Variables

Variable Description
AWS_PROFILE Default AWS profile to use
AWS_REGION Default AWS region
AWS_DEFAULT_REGION Fallback region (if AWS_REGION not set)
AWS_ACCESS_KEY_ID AWS access key
AWS_SECRET_ACCESS_KEY AWS secret key
AWS_SESSION_TOKEN AWS session token (for temporary credentials)
AWS_SHARED_CREDENTIALS_FILE Custom path to credentials file (default: ~/.aws/credentials)
AWS_CONFIG_FILE Custom path to config file (default: ~/.aws/config)
AWS_ENDPOINT_URL Custom endpoint URL (for LocalStack, etc.) - also used for STS AssumeRole
AWS_CA_BUNDLE Custom CA certificate bundle (PEM format) for corporate SSL inspection
SSL_CERT_FILE Alternative to AWS_CA_BUNDLE for custom CA certificates

Corporate Proxy / SSL Inspection

If you're behind a corporate proxy with SSL inspection, taws may fail to connect to AWS services because the proxy's CA certificate is not trusted by default.

To fix this, set AWS_CA_BUNDLE or SSL_CERT_FILE to point to your corporate CA certificate bundle:

# Windows
set AWS_CA_BUNDLE=C:\path\to\corporate-ca-bundle.pem
taws

# Linux/macOS
export AWS_CA_BUNDLE=/path/to/corporate-ca-bundle.pem
taws

The PEM file can contain multiple certificates (certificate chain). taws will load all certificates from the bundle and add them to the trusted root certificates.

Note: This is the same environment variable used by AWS CLI, so if AWS CLI works with your CA bundle, taws should work too.

SSM Connect (EC2 Shell Access)

Press c on a running EC2 instance to open an interactive shell session via AWS Systems Manager.

Requirements:

  • session-manager-plugin must be installed
  • EC2 instance must have SSM Agent running
  • Instance must be running (not stopped/terminated)
  • Linux instances only (Windows not supported via shell)

Note: When you exit the shell session (exit), you'll return to taws.

Known Issues

  • Some resources may require specific IAM permissions not covered by basic read-only policies
  • Total resource count is not displayed due to AWS API limitations (most AWS APIs don't return total count)
  • Some global services (IAM, Route53, CloudFront) always use us-east-1

Important: Before adding a new AWS service, please start a discussion first.
