Dependencies

koala requires Go 1.16 and NodeJS 12.X or newer.

Configuration

addr = ":8081"          # address the server will be listening on
debug = true            # debug mode
cors = false            # enable cors
apply_cmd = "sleep 1"   # command to execute after zonefile change
api_root = "/api"       # path to use for api

[[zones]]
path = "zone"           # zonefile to be edited
origin = "home.arpa."   # zone to be edited
ttl = 3600              # default TTL

[security]
mode = "none"           # guard to use, either 'none', 'oidc' or 'jwt'

[security.oidc]
client_id = ""          # OpenID connect client ID
identity_server = ""    # URL of identity provider

[security.jwt]
secret = ""             # Auth secret for JWT tokens
