List Dag - Terragrunt

Outputs configurations in DAG mode, which sorts configurations by dependency order and groups them by relationship in the dependency graph.

Examples:

By default, configurations are sorted alphabetically:

bash

$ terragrunt list
live/dev/db    live/dev/ec2   live/dev/vpc
live/prod/db   live/prod/ec2  live/prod/vpc

When the --dag flag is used, configurations are sorted by dependency order (dependencies before their dependents):

bash

$ terragrunt list --dag
live/dev/vpc   live/prod/vpc  live/dev/db
live/prod/db   live/dev/ec2   live/prod/ec2

When not used in the long format:

bash

$ terragrunt list -l --dependencies
Type  Path           Dependencies
unit  live/dev/db    live/dev/vpc
unit  live/dev/ec2   live/dev/db, live/dev/vpc
unit  live/dev/vpc
unit  live/prod/db   live/prod/vpc
unit  live/prod/ec2  live/prod/db, live/prod/vpc
unit  live/prod/vpc

Results are sorted by name.

When combined with the long format:

bash

$ terragrunt list -l --dependencies --dag
Type  Path           Dependencies
unit  live/dev/vpc
unit  live/prod/vpc
unit  live/dev/db    live/dev/vpc
unit  live/prod/db   live/prod/vpc
unit  live/dev/ec2   live/dev/db, live/dev/vpc
unit  live/prod/ec2  live/prod/db, live/prod/vpc

When not used in the tree format:

bash

$ terragrunt list -T
.
╰── live
    ├── dev
    │   ├── db
    │   ├── ec2
    │   ╰── vpc
    ╰── prod
        ├── db
        ├── ec2
        ╰── vpc

When combined with the tree format:

bash

$ terragrunt list -T --dag
.

│   ├── live/dev/db
│   │   ╰── live/dev/ec2
