Export and Import Personal Access Tokens (PATs) Enterprise

Administrators who have access to hosts in a Dremio cluster can migrate personal access tokens (PATs) from one cluster to another using the dremio-admin export-pats and dremio-admin import-pats commands.

note

Dremio does not maintain PATs in plaintext. Instead, Dremio uses a secure hashing algorithm to maintain the signatures of secrets. For this reason, the exported data is sensitive but not secret. Administrators may choose to encrypt the exported data using a passphrase. Administrators are responsible for securely transmitting the PAT file to the new cluster (for example, using SSH) and safe disposal of the PAT file and any copies after use.

Requirements

Both the cluster from which you export the PATs and the cluster to which you import the PATs must have the same list of users. That is, usernames for all users must be the same in both clusters. To ensure that the usernames are identical, configure the same authentication mechanism for both clusters, including the list of local users.

Export Syntax

Export syntax

<dremio_home>/bin/dremio-admin export-pats

Get a list of export options

./dremio-admin export-pats -h

Export options command output

    -h, --help
      show usage
    -p, --path
      path to export file
    -s, --secure
      if set, you will be prompted to enter a secret phrase
      Default: false

Import Syntax

Import syntax

<dremio_home>/bin/dremio-admin import-pats

Get a list of import options

./dremio-admin import-pats -h

Import options command output

    -h, --help
      show usage
    -p, --path
      path to import file
    -s, --secure
      if set, you will be prompted to enter a secret phrase
      Default: false
    -i, --ignore-failures
      ignores failures
      Default: false

Migrate PATs

Log in to the master coordinator on the old cluster (the cluster from which you want to export the PATs).
Shut down all nodes. The cluster must be offline to export PATs.
Export the cluster's PATs to a file:
Export cluster PATs
```
<dremio_home>/bin/dremio-admin export-pats --path <path_to_PAT_file>
```
If desired, use the --secure argument. You will be prompted to enter a secret phrase to encrypt the file contents:
Export cluster PATs with --secure argument
```
<dremio_home>/bin/dremio-admin export-pats --path <path_to_PAT_file> --secure
```
To confirm that the export is complete, look for the following confirmation message:
Export confirmation message
```
Exported PATs: PATExportStats{exportedPATCount=3, userDoesNotExistCount=0, tokenExpiredCount=0}
```
Securely transmit the PAT file from the master coordinator in the old cluster to the master coordinator in the new cluster (the cluster to which you want to import the PATs).
Log in to the master coordinator on the new cluster.
Shut down all nodes. The cluster must be offline to import PATs.
Import the PATs from the PAT file:
Import cluster PATs
```
<dremio_home>/bin/dremio-admin import-pats --path <path_to_PAT_file>
```
If you used the --secure argument when exporting the PATs, use it with the import command. You will be prompted to provide the secret phrase to decrypt the file contents:
Import cluster PATs with --secure argument
```
<dremio_home>/bin/dremio-admin import-pats --path <path_to_PAT_file> --secure
```

To confirm that the import is complete, look for the following confirmation message:

Import confirmation message

Stats: PATImportStats{importedPATCount=3, userDoesNotExistCount=0, tokenAlreadyExistsCount=0, tokenExpiredCount=0, exception=null}

If there are any failures, such as PATs that already exist or expire between when the PATs were exported and when they are imported, the entire import fails:

Import failure message

Failed to import PATs.
Stats: PATImportStats{importedPATCount=0, userDoesNotExistCount=0, tokenAlreadyExistsCount=3, tokenExpiredCount=0, exception=com.dremio.common.DeferredException@25930382}
java.lang.RuntimeException: One or more failures occurred while importing PATs
   Suppressed: java.lang.IllegalArgumentException: Token with TID 554087b9-2f86-4d51-911b-8e4a80afad4f already exists
   Suppressed: java.lang.IllegalArgumentException: Token with TID c42a7548-3bd7-4b0a-a9a1-3749f5d570ce already exists
   Suppressed: java.lang.IllegalArgumentException: Token with TID 11c16d5c-bf4f-4057-a085-9296187b3231 already exists

To ignore failures, use the --ignore-failures argument:

Import cluster PATs with ignore-failures argument

<dremio_home>/bin/dremio-admin import-pats --path <path_to_PAT_file> --ignore-failures
