Chapter 7. opm CLI
7.1. Installing the opm CLI
7.1.1. About the opm CLI
Theopm 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 aCatalogSource object, which polls the image at regular intervals to enable frequent updates to installed Operators on the cluster.
Additional resources
- SeeOperator Framework packaging format for more information about the bundle format.
- To create a bundle image using the Operator SDK, seeWorking with bundle images.
7.1.2. Installing the opm CLI
You can install theopm CLI tool on your Linux, macOS, or Windows workstation.
Prerequisites
For Linux, you must provide the following packages. RHEL 8 meets these requirements:
podmanversion 1.9.3+ (version 2.0+ recommended)glibcversion 2.28+
Procedure
- Navigate to theOpenShift mirror site and download the latest version of the tarball that matches your operating system.
Unpack the archive.
For Linux or macOS:
tar xvf <file>
$tar xvf<file>Copy to ClipboardCopied! - For Windows, unzip the archive with a ZIP program.
Place the file anywhere in your
PATH.For Linux or macOS:
Check your
PATH:echo $PATH
$echo$PATHCopy to ClipboardCopied! Move the file. For example:
sudo mv ./opm /usr/local/bin/
$sudomv ./opm /usr/local/bin/Copy to ClipboardCopied!
For Windows:
Check your
PATH:path
C:\> pathCopy to ClipboardCopied! Move the file:
move opm.exe <directory>
C:\> move opm.exe <directory>Copy to ClipboardCopied!
Verification
After you install the
opmCLI, verify that it is available:opm version
$opm versionCopy to ClipboardCopied!

opmprocedures including creating, updating, and pruning catalogs.
7.2. opm CLI reference
Theopm command-line interface (CLI) is a tool for creating and maintaining Operator catalogs.
opm CLI syntax
opm <command> [<subcommand>] [<argument>] [<flags>]
$opm<command>[<subcommand>][<argument>][<flags>]| Flag | Description |
|---|---|
| Skip TLS certificate verification for container image registries while pulling bundles or indexes. |
| When you pull bundles, use plain HTTP for container image registries. |
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 theDeprecated 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>]
$opm generate<subcommand>[<flags>]| Subcommand | Description |
|---|---|
| Generate a Dockerfile for a declarative config index. |
| Flags | Description |
|---|---|
| Help for generate. |
7.2.1.1. dockerfile
Generate a Dockerfile for a declarative config index.
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>]
$opm generate dockerfile<dcRootDir>[<flags>]| Flag | Description |
|---|---|
| Image in which to build catalog. The default value is |
| Extra labels to include in the generated Dockerfile. Labels have the form |
| Help for Dockerfile. |
To build with the official Red Hat image, use theregistry.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.
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.
Theopm 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 theopm subcommands and flags for working with the SQLite database format, such asopm index prune, do not work with the file-based catalog format.
For more information about working with file-based catalogs, see "Additional resources".
