a Simple central config server backed by bbolt with support of callbacks when a property is update.
Server has 3 APIs to put, get, and register webhooks:
curl -X 'POST' \
'localhost:8080/v1/put' \
-H 'Content-Type: application/json' \
-d '{
"namespace": "ns1",
"key": "key1",
"value": "val1"
}'
Would return {"message": "property updated"}
in case of success, 400
response for missing parameters, 500
in case of a server error
curl "localhost:8080/v1/get?key=key1&namespace=ns1"
would return {"value":"val1"}
in case key1
is set in namespace ns1
, 400
response for missing parameters, 500
in case of a server error
curl -H "Content-Type: application/json" -d '{"namespace":"ns1","key":"key1","callback":"http://localhost:8080/ping"}' -X POST localhost:8080/v1/webhook
would return {"message":"callback registered"}
when callback registers successfully, 400
for missing parameters, 500
in case of internal server error
callbacks can be registered even before a property is set, after registering it whenever the property value changes the callback url is called
There is a make target for running it locally, simple execute make run
and it would start it with the default port 8080
.
You can also use the docker image ghcr.io/shadi/simple_config:latest
, it accepts environment variables Port
where you can set the port the web server listens to and GIN_MODE
where you can set it to RELEASE
or DEBUG
