Yor is an open-source tool that helps add informative and consistent tags across infrastructure as code (IaC) frameworks. Today, Yor can automatically add tags to Terraform, CloudFormation, and Serverless Frameworks.

Yor is built to run as a GitHub Action automatically adding consistent tagging logics to your IaC. Yor can also run as a pre-commit hook and a standalone CLI.

Features

• Apply tags and labels on infrastructure as code directory
• Tracing: yor_trace tag enables simple attribution between an IaC resource block and a running cloud resource.
• Change management: git-based tags automatically add org, repo, commit and modifier details on every resource block.
• Custom taggers: user-defined tagging logics can be added to run using Yor.
• Skips: inline annotations enable developers to exclude paths that should not be tagged.
• Dry-Run: get a preview of what tags will be added without applying any.

Pre-commit

  - repo: https://github.com/bridgecrewio/yor
    rev: 0.1.143
    hooks:
      - id: yor
        name: yor
        entry: yor tag -d
        args: ["."]
        language: golang
        types: [terraform]
        pass_filenames: false

Usage

tag : Apply tagging on a given directory.

# Apply all the tags in yor on the directory tree terraform.
yor tag --directory terraform/

# Apply all the tags in yor on the directory terraform, without tagging subdirectories.
yor tag --directory terraform/ --non-recursive

# Apply only the specified tags git_file and git_org
yor tag --directory terraform/ --tags git_file,git_org

# Apply all the tags in yor except the tags starting with git and yor_trace
yor tag --directory terraform/ --skip-tags git*,yor_trace

# Apply only the tags under the git tag group
yor tag --tag-groups git --directory terraform/

# Apply key-value tags on a specific directory
export YOR_SIMPLE_TAGS='{ "Environment" : "Dev" }'
yor tag --tag-groups simple --directory terraform/dev/

# Perform a dry run to get a preview in the CLI output of all of the tags that will be added using Yor without applying any changes to your IaC files.
yor tag -d . --dry-run

# Use an external tag group configuration file path
yor tag -d . --config-file /path/to/conf/file/

# Apply tags to all resources except of a specified type
yor tag -d . --skip-resource-types aws_s3_bucket

# Apply tags with a specifix prefix
yor tag -d . --tag-prefix "module_"

# Apply tags to all resources except with the specified name
yor tag -d . --skip-resources aws_s3_bucket.operations

# Apply tags to only the specified frameworks
yor tag -d . --parsers Terraform,CloudFormation

# Run yor with custom tags located in tests/yor_plugins/example and custom taggers located in tests/yor_plugins/tag_group_example
yor tag -d . --custom-tagging tests/yor_plugins/example,tests/yor_plugins/tag_group_example

-o : Modify output formats.

# Default cli output
yor tag -d . -o cli

# json output
yor tag -d . -o json

# Print CLI output and additional output to a JSON file -- enables programmatic analysis alongside printing human readable results
yor tag -d . --output cli --output-json-file result.json

--skip-dirs : Skip directory paths you can define paths that will not be tagged.

## Run on the directory path/to/files
yor tag -d path/to/files

## Run yor on the directory path/to/files, skipping path/to/files/skip/ and path/to/files/another/skip2/
yor tag -d path/to/files --skip-dirs path/to/files/skip,path/to/files/another/skip2

list-tag

# List tag classes that are built into yor.
yor list-tag-groups

# List all the tags built into yor
yor list-tags

# List all the tags built into yor under the tag group git
yor list-tags --tag-groups git

Supporting comment format

To prevent resource from being tagged, apply the following comment pattern above the resource, currently supported only in Terraform and CloudFormation files.

Example

skip specific resource - #yor:skip

## for terraform files
#yor:Skip 
resource "aws_instance" "example_instance" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
  subnet_id     = aws_subnet.example_subnet.id }

## for cloudformation files
#yor:skip
  ExampleInt:
    Type: AWS::Lambda::Function
    Properties:
      Description: An example template

skip all rsources in the page - #yor:skipAll

## for terraform files
#yor:skipAll
resource "aws_vpc" "example_vpc" {
  cidr_block = "10.0.0.0/16" }

resource "aws_subnet" "example_subnet" {
  vpc_id            = aws_vpc.example_vpc.id
  cidr_block        = "10.0.1.0/24"
  availability_zone = "us-west-1a" }

## for cloudformation files
#yor:skipAll
Resources:
  NewVolume:
    Type: AWS::EC2::Volume
    Properties:
      Size: 100

  NewVolume2:
    Type: AWS::EC2::Volume
      Tags:
        - Key: MyTag
          Value: TagValue
        - Key: Name

What is Yor trace?

yor_trace is a magical tag creating a unique identifier for an IaC resource code block.

Having a yor_trace in place can help with tracing code block to its cloud provisioned resources without access to sensitive data such as plan or state files.

Contributing

Contribution is welcomed!

We are working on extending Yor and adding more parsers (to support additional IaC frameworks) and more taggers (to tag using other contextual data).

To maintain our conventions, please run lint on your branch before opening a PR. To run lint:

golangci-lint run --fix --skip-dirs tests/yor_plugins
