### Filter and Exclude by Tags

- [aws-jmespath-utils](https://github.com/oguzhan-yilmaz/aws-jmespath-utils) dependency is used to enable JMESPath expressions to filter and exclude resources by tags
- Following expressions are used to select anything: (`=`, `*=`, `=*`, `*=*`)
- You can leave one side empty or put a `*` there to discard that sides value
-

### Filter tags

- Select everything

```bash
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].filter_tags(`["="]`, @).Tags'
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].filter_tags(`["*="]`, @).Tags'
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].filter_tags(`["=*"]`, @).Tags'
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].filter_tags(`["*=*"]`, @).Tags'
```

- Find named EC2 Instances

```bash
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].filter_tags(`["Name="]`, @)'
```

- Find AWS MAP migration tagged EC2 Instances

```bash
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].filter_tags(`["map-migrated="]`, @)'
```

### Exclude tags

- Exclude everything

```bash
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].exclude_tags(`["="]`, @).Tags'
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].exclude_tags(`["*="]`, @).Tags'
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].exclude_tags(`["=*"]`, @).Tags'
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].exclude_tags(`["*=*"]`, @).Tags'
```

- Find un-named EC2 Instances

```bash
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].exclude_tags(`["Name="]`, @)'
```

- Find AWS MAP migration un-tagged EC2 Instances

```bash
balcony aws ec2 Instances -js 'DescribeInstances[].Reservations[].Instances[].exclude_tags(`["map-migrated="]`, @)'
```

### Generate Terraform Import Blocks

Terraform v1.5 introduced [import blocks](https://developer.hashicorp.com/terraform/language/import) that allows users to define their imports as code.

`balcony terraform-import ` command generates these import blocks for you.

`balcony terraform-import --list` to see the list of supported resources.

### Generate actual Terraform Resource Code

If you have:

- initialized terraform project
- `import_blocks.tf` file that's generated with `balcony terraform-import` command

you can run `terraform plan -generate-config-out=generated.tf` to generate actual `.tf` resource code.

This feature is achieved with the [balcony-terraform-import Docker Image](https://github.com/oguzhan-yilmaz/balcony/pkgs/container/balcony-terraform-import).

### Interactive Wizard to create balcony import configurations

Balcony doesn't know how to create terraform `import blocks` for all of the AWS resources.

It can be taught how to do it by creating `import-configurations` yaml files, but it's a manual process. This is where the interactive wizard comes in.

Interactive Wizards asks you required questions to automatically create the `import-configurations` yaml files.
