The cockroach userfile get fetches the files stored in the which match the provided pattern, using a SQL connection. If no pattern is provided, all files in the specified (or default, if unspecified) user-scoped file storage will be fetched.
Required privileges
The user must have CONNECT on the target database.
A user can only fetch files from their own user-scoped storage, which is accessed through the used during the upload. CockroachDB will revoke all access from every other user in the cluster except users in the admin role and users explicitly granted access.
If this is your first interaction with user-scoped file storage, you may see an error indicating that you need CREATE privileges on the database. You must first or run a to userfile before attempting to get a file.

Flags
| Flag | Description | |

| --cert-principal-map | A comma-separated list of : 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 “, 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 containing the CA and client certificates and client key. Env Variable:COCKROACH\_CERTS\_DIR Default:${HOME}/.cockroach-certs/ | |
--echo-sql | Reveal the SQL statements sent implicitly by the command-line utility. | |
--url | A to use instead of the other arguments. Env Variable:COCKROACH\_URL Default: no URL | |
--user -u | The that will own the client session. Env Variable:COCKROACH\_USER Default:root | |
Examples
Get a specific file
To get the file named test-data.csv from the default user-scoped storage location for the current user:
Get a file saved to an explicit local file name
To get a file named test-data.csv from a local directory:
Get a file from a non-default userfile URI
If you (e.g., userfile://testdb.public.uploads), use the same URI to fetch it:
Get files that match the provided pattern
To get all files that match a pattern, use *:
