Each hostname is printed to stdout on its own line. The hostname may or may not contain a port number. If the port number is not a part of the hostname, then the port number is assumed to be 8091. ## [](#options)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 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 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. \--client-cert The path to a client certificate used to authenticate when connecting to a cluster. May be supplied with `--client-key` as an alternative to the `--username` and `--password` flags. See the CERTIFICATE AUTHENTICATION section for more information. \--client-cert-password The password for the certificate provided to the `--client-cert` flag, when using this flag, the certificate/key pair is expected to be in the PKCS#12 format. See the CERTIFICATE AUTHENTICATION section for more information. \--client-key The path to the client private key whose public key is contained in the certificate provided to the `--client-cert` flag. May be supplied with `--client-cert` as an alternative to the `--username` and `--password`flags. See the CERTIFICATE AUTHENTICATION section for more information. \--client-key-password The password for the key provided to the `--client-key` flag, when using this flag, the key is expected to be in the PKCS#8 format. See the CERTIFICATE AUTHENTICATION section for more information. ## [](#host-formats)HOST FORMATS When specifying a host for the couchbase-cli command the following formats are expected: * `couchbase://` or `couchbases://` * `http://:` or `https://:` * `:` It is recommended to use the couchbase:// or couchbases:// format for standard installations. The other 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 (or 18091 for https). ## [](#certificate-authentication-mtls-authentication)CERTIFICATE AUTHENTICATION (MTLS AUTHENTICATION) This tool supports authenticating against a Couchbase Cluster by using certificate based authentication (mTLS authentication). To use certificate based authentication a certificate/key must be supplied, there a currently multiple ways this may be done. ### [](#pem-encoded-certificatekey)PEM ENCODED CERTIFICATE/KEY An unencrypted PEM encoded certificate/key may be supplied by using: - `--client-cert `\- `--client-key ` The file passed to `--client-cert` must contain the client certificate, and an optional chain required to authenticate the client certificate. The file passed to `--client-key` must contain at most one private key, the key can be in one of the following formats: - PKCS#1 - PKCS#8 Currently, only the following key types are supported: - RSA - DSA ### [](#pem-encoded-certificatepem-or-der-encrypted-pkcs8-key)PEM ENCODED CERTIFICATE/PEM OR DER ENCRYPTED PKCS#8 KEY An encrypted PKCS#8 formatted key may be provided using: - `--client-cert `\- `--client-key `\- `--client-key-password ` The file passed to `--client-cert` must contain the client certificate, and an optional chain required to authenticate the client certificate. Currently, only the following key types are supported: - RSA - DSA ### [](#encrypted-pkcs12-certificatekey)ENCRYPTED PKCS#12 CERTIFICATE/KEY An encrypted PKCS#12 certificate/key may be provided using: - `--client-cert `\- `--client-cert-password ` The file passed to `--client-cert` must contain the client certificate and exactly one private key. It may also contain the chain required to authenticate the client certificate. Currently, only the following key types are supported: - RSA - DSA ## [](#examples)EXAMPLES To get a list of hostnames for each node in the cluster run the following command: $ couchbase-cli host-list -c 192.168.1.5:8091 --username Administrator \ --password password cb1.mydomain.com:8091 cb2.mydomain.com:8091 cb3.mydomain.com:8091 ## [](#environment-and-configuration-variables)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. CB\_CLIENT\_CERT The path to a client certificate used to authenticate when connecting to a cluster. May be supplied with `CB_CLIENT_KEY` as an alternative to the `CB_USERNAME` and `CB_PASSWORD` variables. See the CERTIFICATE AUTHENTICATION section for more information. CB\_CLIENT\_CERT\_PASSWORD The password for the certificate provided to the `CB_CLIENT_CERT` variable, when using this variable, the certificate/key pair is expected to be in the PKCS#12 format. See the CERTIFICATE AUTHENTICATION section for more information. CB\_CLIENT\_KEY The path to the client private key whose public key is contained in the certificate provided to the `CB_CLIENT_CERT` variable. May be supplied with `CB_CLIENT_CERT` as an alternative to the `CB_USERNAME` and `CB_PASSWORD`variables. See the CERTIFICATE AUTHENTICATION section for more information. CB\_CLIENT\_KEY\_PASSWORD The password for the key provided to the `CB_CLIENT_KEY` variable, when using this variable, the key is expected to be in the PKCS#8 format. See the CERTIFICATE AUTHENTICATION section for more information. ## [](#see-also)SEE ALSO [server-info](couchbase-cli-server-info.md), [server-list](couchbase-cli-server-list.md) ## [](#couchbase-cli)COUCHBASE-CLI Part of the [couchbase-cli](couchbase-cli.md) suite
