How did you install Redash: dockerhub

I suppose REDASH_REDIS_URL or REDIS_URL has problems

I copy pasted your docker-compose.yml file (with a single change: using the 4.0.0-rc.1 image) and everything works just fine.

$ docker-compose run --rm server create_db

Not sure what went wrong in your case, but it looks like a local setup issue. 🤷‍♂️

Feel free to reopen if you have more details.

Please install redis-server by sudo apt-get install redis-server. And run redis-sever in background.

For me, this problem is solved by installing and running redis-server.
