Simple cli for prepping the env for a run of a life.io service.

svcenv

Utility for setting up Life.io service environments.

Installation

# Global
$ npm install -g @lifeio/svcenv

# Local
$ npm install @lifeio/svcenv (run with npx)

Usage

This utility is primarily intended for use with ECS task definitions to initialize a microservice container.

  Usage: svcenv [OPTIONS] ServiceName SecretId [outputDir]
  
  Options:
      -e,  --envFile      Name of envFile to dump in outputDir (default = ./.env)
      -h,  --help         Display help screen
      -p,  --profile      If using local ~/.aws credentials
      -r,  --region       Region to use for secrets lookup
      -v,  --version      Display version

Environment

It will pull secrets stored in AWS Secerets Manager under the SecretId key and dump them to an env file (default=./.env).

NODEID

The utilty will add a NODEID to the created .env file as well, using the following rules:

1. If it detects a NODEID from the current environment, this value will be written to the file as is.
2. If it finds the variable ECS_CONTAINER_METADATA_URI in the environment it will download the meta data and create a NODEDID using the ServiceName command line argument and the first eight characters of the ECS Task Id.
3. If the ECS_CONTAINER_METADATA_URI variable is not present OR there is an error extracting the Task Id, NODEID will be ServiceName-Date.now-5 digit random number.

S3 DEPLOYMENT BUCKET

If the variable LIFEIO_DEPLOYMENT_BUCKET is found in the process env or the AWS Secret Manager env, it will be used to download the contents of the bucket to the outputDir (./).

IMPORTANT - The LIFEIO_DEPLOYMENT_BUCKET variable must be formatted s3://[bucket]/[keyPrefix].

AWS Authentication

The utility can authenticate via IAM, or if running outside of AWS via authentication env vars, or it will use the ~/.aws/credentials file. If using the credentials file, the --profile argument can be used to select the correct profile.

DEBUGGING

The utilty uses the debug module. To turn on debugging add DEBUG=* to the command line or your environment.
