Flags

General

Flag Description
--all Apply to all bundles or activation requests.

Client connection

Flag Description
--host The server host and port number to connect to. This can be the address of any node in the cluster.

Env Variable: COCKROACH_HOST
Default: localhost:26257
--port

-p
The server port to connect to. Note: The port number can also be specified via --host.

Env Variable: COCKROACH_PORT
Default: 26257
--user

-u
The SQL user that will own the client session.

Env Variable: COCKROACH_USER
Default: root
--insecure Use an insecure connection.

Env Variable: COCKROACH_INSECURE
Default: false
--cert-principal-map A comma-separated list of <cert-principal>:<db-principal> mappings. This allows mapping the principal in a cert to a DB principal such as node or root or any SQL user. This is intended for use in situations where the certificate management system places restrictions on the Subject.CommonName or SubjectAlternateName fields in the certificate (e.g., disallowing a CommonName like node or root). If multiple mappings are provided for the same <cert-principal>, the last one specified in the list takes precedence. A principal not specified in the map is passed through as-is via the identity function. A cert is allowed to authenticate a DB principal if the DB principal name is contained in the mapped CommonName or DNS-type SubjectAlternateName fields.
--certs-dir The path to the certificate directory containing the CA and client certificates and client key.

Env Variable: COCKROACH_CERTS_DIR
Default: ${HOME}/.cockroach-certs/
--url A connection URL to use instead of the other arguments. To convert a connection URL to the syntax that works with your client driver, run cockroach convert-url.

Env Variable: COCKROACH_URL
Default: no URL

See Client Connection Parameters for more details.
