ip-family

      +

      Edits cluster IP family settings

      SYNOPSIS

      couchbase-cli ip-family [--cluster <url>] [-username <username>]
    [--password <password>] [--get] [--set] [--ipv4] [--ipv4only]
    [--ipv6] [--ipv6only]

      DESCRIPTION

      This command changes the IP family used for inter-cluster communication. To do this it will execute a number of instructions in each node in the cluster. The clusters names must be FQDN and not IP addresses. It also provides an option to retrieve the current IP family being used.

      OPTIONS

      -c
      --cluster

      Specifies the hostname of a node in the cluster. See the HOST FORMATS section for more information on specifying a hostname.

      -u
      --username <username>

      Specifies the username of the user executing the command. If you do not have a user account with permission to execute the command then it will fail with an unauthorized error.

      -p
      --password <password>

      Specifies the password of the user executing the command. If you do not have a user account with permission to execute the command then it will fail with an unauthorized error. If this argument is specified, but no password is given then the command will prompt the user for a password through non-echoed stdin. You may also specify your password by using the environment variable CB_REST_PASSWORD.

      --get

      Show current IP family.

      --set

      Change the cluster IP family, specify the IP family to be used using the --ipv4 or --ipv6 flags.

      --ipv4

      When specified together with --set it will change the cluster to use IPv4 for communication between the nodes. It will still be possible for traffic to go over IPv6 from clients.

      --ipv4only

      When specified together with --set it will change the cluster to only use IPv4. It will not blind to any IPv6 addresses, all traffic will be over IPv4

      --ipv6

      When specified together with --set it will change the cluster to use IPv6 for communication between the nodes. It will still be possible for traffic to go over IPv4 from clients.

      --ipv6only

      When specified together with --set it will change the cluster to only use IPv6. It will not blind to any IPv4 addresses, all traffic will be over IPv6.

      HOST FORMATS

      When specifying a host for the couchbase-cli command the following formats are expected:

      • couchbase://<addr>

      • <addr>:<port>

      • http://<addr>:<port>

      It is recommended to use the couchbase://<addr> format for standard installations. The other two formats allow an option to take a port number which is needed for non-default installations where the admin port has been set up on a port other that 8091.

      EXAMPLES

      For a cluster with nodes [cb1.com, cb2.com, cb3.com] communicating via IPv4 we can change the IP family being used to IPv6 by using the following command.

      $ couchbase-cli ip-family -c http://cb1.com:8091 -u Administrator \
  -p password --set --ipv6

      This command will configure each node in the cluster to use IPv6. To check what family is being used use the command below:

      $ couchbase-cli ip-family -c http://cb1.com:8091 -u Administrator \
  -p password --get

      ENVIRONMENT AND CONFIGURATION VARIABLES

      CB_REST_USERNAME

      Specifies the username to use when executing the command. This environment variable allows you to specify a default argument for the -u/--username argument on the command line.

      CB_REST_PASSWORD

      Specifies the password of the user executing the command. This environment variable allows you to specify a default argument for the -p/--password argument on the command line. It also allows the user to ensure that their password are not cached in their command line history.
