thanks for the reply ，I've found a way

@Sunnnner can you please specify the way you found. I am also facing the same issue.

For those still facing the same issue, you need to add the host to environment file /opt/redash/env
For example:
REDASH_REDIS_URL=redis://ubuntu_redis_1:6379/0

Similarly you might as well face issue for postgres.
