add-leaf

Description

Add the node as a leaf to the cluster.

This command will add the specified node as a leaf node and must be run on the Master Aggregator.

When using this command, you should use --memsql-id rather than --host and/or --port.

The --password flag is a required and specifies the SingleStore root password. You can use this flag in conjunction with the --user flag to specify a SingleStore user that is different from the root user and the user’s password.

Note that the MEMSQL_PASSWORD environment variable is a safer alternative option for setting the password.

Wrap the password in single quotes (') to avoid having special characters included in the password interpreted by the shell. For example: sdb-admin add-leaf --host memsql-01 --port 3306 --password '<<fooismypassword'

Examples

sdb-admin add-leaf --memsql-id 0123ABCDEF --password 'foo'
sdb-admin add-leaf --host memsql-01 --port 3306 --password 'foo'

Usage

Usage:
sdb-admin add-leaf [flags]
For flags that can accept multiple values (indicated by VALUES after the name of the flag),
separate each value with a comma.
Flags:
--availability-group int The availability group to assign to the leaf
-h, --help Help for add-leaf
--host string The cluster-addressable hostname for the leaf node
--memsql-id MemsqlID The node ID of the node to be added as a leaf node
-p, --password STRING The database user's password. If a password is specified on the command line, it must not contain an unescaped '$' character as it will be replaced by the shell.
If a password is not specified on the command line, Toolbox will attempt to read the password from the ‘MEMSQL_PASSWORD’ environment variable.
If this variable is present but does not contain a value, or if the variable does not exist, Toolbox will prompt for a password
--port PORT The cluster-addressable port for the leaf node
--skip-validate-env Skip environment validation
--user string The database user (default "root")
Global Flags:
--backup-cache FILE_PATH File path for the backup cache
--cache-file FILE_PATH File path for the Toolbox node cache
-c, --config FILE_PATH File path for the Toolbox configuration
--disable-colors Disable color output in console, which some terminal sessions/environments may have difficulty with
--disable-spinner Disable the progress spinner, which some terminal sessions/environments may have issues with
-j, --json Enable JSON output

--runtime-dir DIRECTORY_PATH Where to store Toolbox runtime data

--ssh-max-sessions POSITIVE_INTEGER Maximum number of SSH sessions to open per host, must be at least 3
--ssh-strict-host-key-checking Enable strict host key checking for SSH connections
--ssh-user-known-hosts-file FILE_PATH Path to the user known_hosts file for SSH connections. If not set, /dev/null will be used
