Connections and credentials

Find endpoints

Open a service and select Connect. The dialog shows:

  • the ClickHouse native endpoint on port 9000;
  • the ClickHouse HTTP endpoint on port 8123;
  • the ElasticQuery native and HTTP endpoints when ElasticQuery is enabled;
  • the ClickStack URL when available.

Use the ClickHouse endpoint for reads, writes, and DDL. ElasticQuery endpoints are read-only.

Retrieve the default password

  1. Open the service.
  2. Select Settings.
  3. Select Access.
  4. Select Reveal beside the default administrator password.

Treat the password as a secret. Do not paste it into tickets, chat messages, or source control.

Native client

clickhouse-client \
  --host <clickhouse-host> \
  --port 9000 \
  --user default \
  --password

The client prompts for the password.

HTTP

curl --user 'default:<password>' \
  'http://<clickhouse-host>:8123/?query=SELECT%20version()'

Use TLS and the externally assigned hostname when the platform exposes a secure load balancer.

Manage additional users

The default administrator can create users and grants with ClickHouse SQL. Use separate least-privilege users for applications instead of sharing the administrator credential.
