Working with replicasets

Displaying status of all replica sets

To view the status of all replica sets of an application in the current tt environment, run tt replicaset status with the application name:

$ tt replicaset status myapp

Displaying status of a single replica set

To view the status of a single replica set of an application, run tt replicaset status with a name or a URI of an instance from this replica set:

$ tt replicaset status myapp:storage-001-a

For a replica outside the current tt environment, specify its URI and access credentials:

$ tt replicaset status 192.168.10.10:3301 -u myuser -p p4$$w0rD

Learn about other ways to provide user credentials in Authentication.

Authentication

Use one of the following ways to pass the credentials of a Tarantool user when connecting to the instance:

• The -u (--username) and -p (--password) options:

  $ tt replicaset status 192.168.10.10:3301 -u myuser -p p4$$w0rD
  

• The connection string:

  $ tt replicaset status myuser:p4$$w0rD@192.168.10.10:3301
  

• Environment variables TT_CLI_USERNAME and TT_CLI_PASSWORD:

  $ export TT_CLI_USERNAME=myuser
  $ export TT_CLI_PASSWORD=p4$$w0rD
  $ tt replicaset status 192.168.10.10:3301
  

Selecting the application orchestrator manually

You can specify the orchestrator to use for the application using the following options:

• --config for applications that use YAML cluster configuration (Tarantool 3.x or later).
• --cartridge for Cartridge applications (Tarantool 2.x).
• --custom for any other orchestrators used on Tarantool 2.x clusters.

$ tt replicaset status myapp --config
$ tt replicaset status my-cartridge-app --cartridge

If an actual orchestrator that the application uses does not match the specified option, an error is raised.

Options

--cartridge¶

Force the Cartridge orchestrator for Tarantool 2.x clusters.

--config¶

Force the YAML configuration orchestrator for Tarantool 3.0 or later clusters.

--custom¶

Force a custom orchestrator for Tarantool 2.x clusters.

-u USERNAME, --username USERNAME¶

A Tarantool user for connecting to the instance.

-p PASSWORD, --password PASSWORD¶

The user’s password.

--sslcertfile FILEPATH¶

The path to an SSL certificate file for encrypted connections.

--sslkeyfile FILEPATH¶

The path to a private SSL key file for encrypted connections.

--sslcafile FILEPATH¶

The path to a trusted certificate authorities (CA) file for encrypted connections.

--sslciphers STRING¶

The list of SSL cipher suites used for encrypted connections, separated by colons (:).
