Chapter 6. opm CLI
6.1. Installing the opm CLI
6.1.1. 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.

6.1.2. 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:
-
podmanversion 1.9.3+ (version 2.0+ recommended) -
glibcversion 2.28+
-
Procedure
- Navigate to the OpenShift 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>
- 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
Move the file. For example:
$ sudo mv ./opm /usr/local/bin/
For Windows:
Check your
PATH:C:\> path
Move the file:
C:\> move opm.exe <directory>
Verification
After you install the
opmCLI, verify that it is available:$ opm version

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.
