Overview

PFM Settings

Top level settings defined and loaded here. This class loads the user config file located at .pfm/config

AWS_REGION default -> 'us-east-1'

  • The AWS region to work in. This will eventually become the AWS_REGION environment variable and can be used with other AWS API operations.

RUBOCOP_RULES_FILE default -> '.rubocop.yml'

  • Set the path to the global .rubocop.yml rules file. This file will be used for all server builds when running syntax checks.

FOODCRITIC_RULES_FILE default -> '.foodcritic'

  • Set the path to the global .foodcritic rules file. This file will be used for all server builds when running semantics checks.

BUILD_BASE_DIR default -> 'builds'

  • Set the root path to the builds directory. This should be where top level server builds are located. Ex:

    .
    ├── builds
    │   ├── app-axpdb
    │   └── app-axpwa
    

INF_BASE_DIR default -> 'inf'

  • Set the path to the top level infrastructure directory. Ex:

    .
    ├── inf
    │   ├── env
    │   ├── tasks
    │   └── tf
    

PUBLISH_BUCKET default -> ''

  • The top level bucket where deployment packages are stored in S3.

PUBLISH_PREFIX default -> ''

  • The prefix to the deployment package storage location. Ex: s3://PUBLISH_BUCKET/PUBLISH_PREFIX/package.name

PACKER_VERSION <em>default -> 'default from packer/binary'

  • The version of Hashicorp Packer to use for builds

TERRAFORM_VERSION <em>default -> 'default from terraform/binary'

  • The version of Hashicorp Terraform to use for deployments

Note that if you change these settings from the default, be sure you commit the .pfm/config file.

BUILD_BASE_DIR: 'builds'
