7.1. Installing the opm CLI

7.1.1. About the opm CLI

The opm CLI tool is provided by the Operator Framework for use with the Operator bundle format. This tool allows you to create and maintain catalogs of Operators from a list of Operator bundles that are similar to software repositories. The result is a container image which can be stored in a container registry and then installed on a cluster.

A catalog contains a database of pointers to Operator manifest content that can be queried through an included API that is served when the container image is run. On OpenShift Container Platform, Operator Lifecycle Manager (OLM) can reference the image in a catalog source, defined by a CatalogSource object, which polls the image at regular intervals to enable frequent updates to installed Operators on the cluster.

7.1.2. Installing the opm CLI

You can install the opm CLI tool on your Linux, macOS, or Windows workstation.

Prerequisites

  • For Linux, you must provide the following packages. RHEL 8 meets these requirements:

    • podman version 1.9.3+ (version 2.0+ recommended)
    • glibc version 2.28+

Procedure

  1. Navigate to the OpenShift mirror site and download the latest version of the tarball that matches your operating system.
  2. Unpack the archive.

    • For Linux or macOS:

      $ tar xvf <file>
    • For Windows, unzip the archive with a ZIP program.
  3. Place the file anywhere in your PATH.

    • For Linux or macOS:

      1. Check your PATH:

        $ echo $PATH
      2. Move the file. For example:

        $ sudo mv ./opm /usr/local/bin/
    • For Windows:

      1. Check your PATH:

        C:\> path
      2. Move the file:

        C:\> move opm.exe <directory>

Verification

  • After you install the opm CLI, verify that it is available:

    $ opm version

7.2. opm CLI reference

The opm command-line interface (CLI) is a tool for creating and maintaining Operator catalogs.

opm CLI syntax

$ opm <command> [<subcommand>] [<argument>] [<flags>]

Table 7.1. Global flags
FlagDescription

-skip-tls-verify

Skip TLS certificate verification for container image registries while pulling bundles or indexes.

--use-http

When you pull bundles, use plain HTTP for container image registries.

Important

The SQLite-based catalog format, including the related CLI commands, is a deprecated feature. Deprecated functionality is still included in OpenShift Container Platform and continues to be supported; however, it will be removed in a future release of this product and is not recommended for new deployments.

For the most recent list of major functionality that has been deprecated or removed within OpenShift Container Platform, refer to the Deprecated and removed features section of the OpenShift Container Platform release notes.

7.2.1. generate

Generate various artifacts for declarative config indexes.

Command syntax

$ opm generate <subcommand> [<flags>]

Table 7.2. generate subcommands
SubcommandDescription

dockerfile

Generate a Dockerfile for a declarative config index.

Table 7.3. generate flags
FlagsDescription

-h, --help

Help for generate.

7.2.1.1. dockerfile

Generate a Dockerfile for a declarative config index.

Important

This command creates a Dockerfile in the same directory as the <dcRootDir> (named <dcDirName>.Dockerfile) that is used to build the index. If a Dockerfile with the same name already exists, this command fails.

When specifying extra labels, if duplicate keys exist, only the last value of each duplicate key gets added to the generated Dockerfile.

Command syntax

$ opm generate dockerfile <dcRootDir> [<flags>]

Table 7.4. generate dockerfile flags
FlagDescription

-i, --binary-image (string)

Image in which to build catalog. The default value is quay.io/operator-framework/opm:latest.

-l, --extra-labels (string)

Extra labels to include in the generated Dockerfile. Labels have the form key=value.

-h, --help

Help for Dockerfile.

Note

To build with the official Red Hat image, use the registry.redhat.io/openshift4/ose-operator-registry:v4.13 value with the -i flag.

7.2.2. index

Generate Operator index for SQLite database format container images from pre-existing Operator bundles.

Important

As of OpenShift Container Platform 4.11, the default Red Hat-provided Operator catalog releases in the file-based catalog format. The default Red Hat-provided Operator catalogs for OpenShift Container Platform 4.6 through 4.10 released in the deprecated SQLite database format.

The opm subcommands, flags, and functionality related to the SQLite database format are also deprecated and will be removed in a future release. The features are still supported and must be used for catalogs that use the deprecated SQLite database format.

Many of the opm subcommands and flags for working with the SQLite database format, such as opm index prune, do not work with the file-based catalog format.

For more information about working with file-based catalogs, see "Additional resources".
