Flags
- The
deleteandcancelsubcommands support one general-use flag. - All
statement-diagsubcommands support several client connection and logging flags.
General
| Flag | Description |
|---|---|
--all |
Apply to all bundles or activation requests. |
Client connection
| Flag | Description |
|---|---|
--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_URLDefault: no URL |
--host |
The server host and port number to connect to. This can be the address of any node in the cluster. Env Variable: COCKROACH_HOSTDefault: localhost:26257 |
--port-p |
The server port to connect to. Note: The port number can also be specified via --host. Env Variable: COCKROACH_PORTDefault: 26257 |
--user-u |
The SQL user that will own the client session. Env Variable: COCKROACH_USERDefault: root |
--insecure |
Use an insecure connection. Env Variable: COCKROACH_INSECUREDefault: 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_DIRDefault: ${HOME}/.cockroach-certs/ |
See Client Connection Parameters for more details.
