Environment Variables

An .env-file is automatically generated from the .env template If you want to extend the .env file feel free to do so in the generated code

or if you want to customize the generated .enf file before it is generated take a look at writing your own templates The generated microservice uses the following environment variables (with their respective default values):

SERVICE_PORT = "8080"
SERVER_URL = "{{ .server.url }}"
LOG_LEVEL = "DEBUG"     # available levels are ERROR, WARN, INFO, DEBUG and TRACE
OPA_RULES= "path/to/admin/policy"
TRACING_ENABLED = false
SCHEMA_VALIDATION_ENABLED = true

Also per channel the subject will be set via an environment variable:

{channel_name}_SUBJECT = "{subject}"    # for normal pub_sub channels
{channel_name}_QUEUE = "{subject}"      # for nats queue channels
{channel_name}_STREAM = "{subject}"     # for nats jetstream channels

And for OPA

OPA_ENABLED = false                 # choose if OPA should be enabled
#OPA_REMOTE_URL = "localhost:4042"  # pick the url for an opa server
#OPA_LOCAL_WASM_PATH = "some/path"  # pick the path of a to wasm compiled rego file
