AKJG - API Key JWT Generator

A Simple service to generate JWT by API Key (with configurable claims)

Sample Config

port = 3000

jwt-secret = "abc" # generate a strong secret (https://cloud.google.com/network-connectivity/docs/vpn/how-to/generating-pre-shared-key)
jwt-expiry-mins = 10

[api-key-jwt-map]
    
    # Setup API Keys and associated JWT claims
    [api-key-jwt-map."f30d3c1a-4144-4321-ba6c-bed3cf4a7308"]
    sub = "1"
    name = "test-user"
    admin = false
       [api-key-jwt-map."f30d3c1a-4144-4321-ba6c-bed3cf4a7308"."https://hasura.io/jwt/claims"]
       x-hasura-default-role = "user"
       x-hasura-allowed-roles = ["editor","user", "mod"]
       x-hasura-org-id = "123"

[log]
format = "text" # valid values are text or json
output = "term" # valid values are term or file
#log-directory = "./logs/" # needed if writing logs to a file
level = "debug"

Deploy using Docker

# docker run --rm -p 3000:3000 -v ./config.toml:/app/configs/config.toml pvik/akjg:latest
