not able to connect superset to druid

I have Druid and superset running locally, but I am not able to connect them together.
I have sample data wikiticker in Druid. I already installed pydruid with pip3: pip3 install pydruid (I am not sure if I need to install this to any particular location).
I have also installed superset using docker-compose locally using This Link, However, I am not able to connect Druid with Superset. I went to Data->Databases->add database. In Connection, I gave Database name as Druid and not sure what to give in SQLALCHEMY URI* .
I tried these:

druid//admin:admin@localhost:8082/wikiticker

pydruid//admin:admin@localhost:8082/wikiticker

druid://admin:admin@localhost:8082/druid/v2/sql

but nothing is working.

There is a good chance that you didn't add the Root Certificate. You can either do that or disable SSL verification. See the documentation here: https://superset.apache.org/docs/databases/druid

As per documentation the connection string should look like this (third variant in the question):

druid://<User>:<password>@<Host>:<Port-default-9088>/druid/v2/sql

Why you cannot connect might be, because of your docker setup. In the context of your superset docker container localhost refers to that particular docker container. For example the database and the redis cache are referred to as db and redis for the connection setup within the docker-compose.yml and the environment variables set in .env.

So you could extend the docker-compose.yml to include the druid container, named druid as well and then connect to it like this:

druid://admin:admin@druid:PORTTHATYOUEXPOSED/druid/v2/sql

As far as I know, Druid has no built-in authentication. The SQLALCHEMY_URI string should be druid+https://localhost:8082/druid/v2/sql/ (or druid+http://localhost:8082/druid/v2/sql/ if you're using HTTP).
