Run

The following runs golinks with an in-memory datastore. See Configuration for more options.

golinks

Migration

Some storage backends require running a migration.

golinks migrate

Deploy

• AWS SAM - deploy golinks as an AWS serverless application.

Configuration

Configuration is managed by environment variables.

• GOLINKS_PORT
  • Specifies which port the application listens on.
  • default: 8080
  • e.g. 8081
• GOLINKS_STORAGE_TYPE
  • Specifies which storage backend is used to maintain the links. See the Storage subsection for more information.
  • default: memory
  • options: memory, dynamodb

Memory

GOLINKS_STORAGE_TYPE=memory

No further configuration.

This is primarily for development purposes. All links are stored in a in-memory hashmap. Data is lost when the application is terminated.

Migration

Running migration with this storage backend is a no-op.

Dynamodb

GOLINKS_STORAGE_TYPE=dynamodb

Uses Amazon Web Services' (AWS) DynamoDB to maintain the links. You can specify your Amazon Credentials in the typical fashion. The IAM user must have at least have access to read and write to the GOLINKS_STORAGE_TABLENAME. The IAM user must also be able to create tables to run the migration.

• GOLINKS_STORAGE_REGION
  • Specifies the AWS region to use.
  • default: us-west-2
• GOLINKS_STORAGE_ENDPOINT
  • Specifies the AWS endpoint to use.
  • default: http://localhost:8000
  • e.g. https://dynamodb.us-west-2.amazonaws.com
• GOLINKS_STORAGE_TABLENAME
  • Specifies the name of the DynamoDB table to use.
  • default: Links
  • e.g. GoLinksLinks

Migration

Running migration with this storage backend creates the DynamoDB table specified by GOLINKS_STORAGE_TABLENAME. If the table already exists, this is a no-op.
