The OLP CLI supports the following:

local catalog list

Lists all local catalogs and returns a catalog name on a separate line.

To get more information about a catalog, see the olp local catalog show command.

olp local catalog list [filter] [command options]

Optional parameters:

  • [filter] Freeform text used to filter the catalog list. The filter checks if the catalog HRN contains the filter string.
  • --json Displays the command result in JSON format.
  • --quiet Displays catalog HRNs, each on a new line.

Example with filtering:

olp local catalog list "first-catalog-example-id" --json

Output:

{"results": {"items": [
    {"hrn": "hrn:local:data:::first-catalog-example-id"}
]}}

Example without filtering:

olp local catalog list --json

Output:

{"results": {"items": [
    {"hrn": "hrn:local:data:::first-catalog-example-id"},
    {"hrn": "hrn:local:data:::second-catalog-example-id"}
]}}

local catalog create

Creates an empty local catalog.

olp local catalog create <catalog ID> <catalog name> --summary <catalog summary> [command options]

Required parameters:

  • <catalog ID> The ID that is used as a hint to create the catalog HRN.
  • <catalog name> The human-readable name of the catalog. Overrides any values provided with the --config parameter through the command line.
  • --description <catalog description> A detailed description of the catalog and its contents. Enclose the description in quotes.
  • --summary <catalog summary> A one-line summary of the catalog contents. Overrides any values provided with the --config parameter through the command line.

Note

You can also specify the summary for a catalog through a configuration file referenced by the --config option.

Optional parameters:

  • --config <path to config file> The path and name of the configuration file.
  • --tags <tag1 tag2 ...> Catalog keywords used for search discovery.
  • --json Displays the catalog HRN in JSON format.
  • --quiet Displays the catalog HRN.

Example:

The command below creates the empty local catalog first-catalog-example, and displays the catalog's HRN in the output. To pass multiple arguments to a parameter that accepts them, separate the arguments with spaces.

olp local catalog create first-catalog-example-id first-catalog-example --summary "A new summary"

Output:

Catalog hrn:local:data:::first-catalog-example-id has been created

Example:

The command below creates an empty local catalog second-catalog-example with two tags (tag1 and tag2) in the platform and displays the catalog's HRN in the console output.

olp local catalog create second-catalog-example-id second-catalog-example --tags tag1 tag2 --summary "A new summary"

Output:

Catalog hrn:local:data:::second-catalog-example-id has been created

local catalog update

Updates an existing local catalog with the configuration specified in a configuration file.

olp local catalog update <catalog HRN> [command options]

Warning

Catalog configuration changes

Like in the platform, you are not allowed to change a local catalog's layer configuration.

Required parameters:

  • <catalog HRN> The HRN of the catalog.

Optional parameters:

  • --config <path to config file> The path of the file with the updated configuration.
  • --name <catalog name> The human-readable name of the catalog. Overrides values provided with --config through the command line.
  • --summary <catalog summary> A one-line summary of the catalog contents. Overrides values provided with --config through the command line.
  • --description <catalog description> A detailed description of the catalog and its contents. Enclose the description in quotes.
  • --tags <tag1 tag2 ...> Catalog keywords used for search discovery. To unset tags, use --tags [].
  • --quiet Displays empty output with no additional information.

Example:

olp local catalog update hrn:local:data:::first-catalog-example-id --config path/to/config.json

Example configuration for a catalog with a volatile layer:

{
  "name": "volatile-volatile-catalog",
  "summary": "A short summary",
  "description": "A longer description about what the catalog contains",
  "tags": [
    "tag1",
    "tag2"

      "contentType": "application/x-protobuf",
      "crc": "CRC-32C",

      "contentType": "application/x-protobuf"
    }
  ]
}

Note

The olp local catalog inspect command starts a local Data API server and does not return control to the user until the process is killed.

Example:

The command below opens an external browser and navigates to the hrn:local:data:::first-catalog-example-id catalog overview page in the platform portal.

olp local catalog inspect hrn:local:data:::first-catalog-example-id

Output:

A browser page should be opened shortly. If the browser does not show up, manually navigate to http://127.0.0.1:31005/inspector/?environment=here&hrn0=hrn:local:data:::first-catalog-example-id
Press CTRL-C to stop the local inspector...
