Installing the OpenShift Serverless Logic Knative Workflow plugin

Installing the OpenShift Serverless Logic Knative Workflow plugin for Linux

If you are using a Linux distribution that does not have RPM or another package manager installed, you can install the Knative Workflow plugin.

Prerequisites

  • You have installed the Knative (kn) command-line interface (cli).

  • If you are not using RHEL or Fedora, ensure that the libc library is installed in a directory on your path.

    If the libc library is not available, you might see the following error when you run commands:

    $ kn: No such file or directory
Procedure

  1. Download the latest tar archive suitable for your environment, from the Serverless Logic download mirror page.

  2. Extract the Knative Workflow plugin binary file by running the following command:

    $ tar xvzf <tar_archive>

  3. Rename the extracted Knative Workflow plugin binary file to kn-workflow by running the following command:

    $ mv <filename> kn-workflow

  4. Install the kn-workflow command as the Knative cli plugin:

    1. Make the binary file executable by running the following command:

      $ chmod +x /usr/local/bin/kn-workflow

    2. Copy the kn-workflow binary file to a directory in the /usr/local/bin path by running the following command:

      $ cp <path/to/downloaded/kn-workflow> /usr/local/bin/kn-workflow
Verification

  • Run the following command to verify that the kn-workflow plugin is installed successfully:

    $ kn plugin list

Installing the OpenShift Serverless Logic Knative Workflow plugin for macOS

If you are using macOS, you can install the Knative Workflow plugin as a binary file.

On macOS, some systems might block the application from running due to security policies. To fix this issue, click System Preferences → Security & Privacy → General to approve the application to run. For more information, see the Open a Mac app from an unidentified developer Apple support article.
Prerequisites

  • You have installed the Knative (kn) command-line interface (cli).

Procedure

  1. Download the latest tar archive suitable for your environment, from the Serverless Logic download mirror page.

  2. Extract the Knative Workflow plugin binary file by running the following command:

    $ tar xvzf <tar_archive>

  3. Rename the extracted Knative Workflow plugin binary file to kn-workflow by running the following command:

    $ mv <filename> kn-workflow

  4. Install the kn-workflow command as the Knative cli plugin:

    1. Make the binary file executable by running the following command:

      $ chmod +x /usr/local/bin/kn-workflow

    2. Copy the kn-workflow binary file to a directory in the /usr/local/bin path by running the following command:

      $ cp <path/to/downloaded/kn-workflow> /usr/local/bin/kn-workflow
Verification

  • Run the following command to verify that the kn-workflow plugin is installed successfully:

    $ kn plugin list

Installing the OpenShift Serverless Logic Knative Workflow plugin for Windows

If you are using Windows, you can install the Knative Workflow plugin.

Prerequisites

  • You have installed the Knative (kn) command-line interface (cli).

Procedure

  1. Download the latest zip archive suitable for your environment, from the Serverless Logic download mirror page.

  2. Extract the Knative Workflow plugin binary file using PowerShell by running the following command:

    $ Expand-Archive -Path <filename>.zip -DestinationPath <destination>

  3. Rename the extracted Knative Workflow plugin binary file to kn-workflow by running the following command:

    $ Rename-Item -Path <destination>\<filename>.exe -NewName kn-workflow.exe

  4. Install the kn-workflow command as the Knative cli plugin:

    On Windows, files with a .exe extension are treated as executable by default, so you do not need to change permissions.

    1. Move the kn-workflow.exe file to a directory in your PATH by running the following command:

      $ move C:\path\to\kn-workflow.exe "C:\Program Files"

    2. Copy the kn-workflow binary file to a directory in your PATH by running the following command:

      $ Copy-Item -Path <destination>\kn-workflow.exe -Destination "C:\Program Files\kn-workflow.exe"
Verification

  • Run the following command to verify that the kn-workflow plugin is installed successfully:

    $ kn plugin list

Installing the OpenShift Serverless Logic Knative Workflow plugin using the artifacts image

Prerequisites

  • You have installed the Knative (kn) cli.

  • You have installed Podman on your local machine.

Procedure

  1. Download the Knative Workflow plugin using the logic-kn-workflow-cli-artifacts-rhel8 image by running the following commands:

    1. Log in to the Red Hat Registry by running the following command:

      $ podman login registry.redhat.io

      You can use your Red Hat Customer Portal account or a registry service account.

    2. Set a variable for KN_IMAGE to start the logic-kn-workflow-cli-artifacts-rhel8 image by running the following command:

      $ export KN_IMAGE=registry.redhat.io/openshift-serverless-1/logic-kn-workflow-cli-artifacts-rhel8:1.33.0

    3. Set a variable for KN_CONTAINER_ID by running the following command:

      $ export KN_CONTAINER_ID=$(podman run -di $KN_IMAGE)

    4. Copy the Knative Workflow plugin binary file by running the following command:

      $ podman cp $KN_CONTAINER_ID:<path_to_binary> .

      where <path_to_binary> is the path to the file for your environment:

      Environment Path to binary file

      Linux amd64 architecture

      /usr/share/kn/linux_amd64/kn-workflow-linux-amd64.tar.gz

      Linux arm64 architecture

      /usr/share/kn/linux_arm64/kn-workflow-linux-arm64.tar.gz

      macOS amd64 architecture

      /usr/share/kn/macos_amd64/kn-workflow-macos-amd64.tar.gz

      macOS arm64 architecture

      /usr/share/kn/macos_arm64/kn-workflow-macos-arm64.tar.gz

      Windows amd64 architecture

      /usr/share/kn/windows/kn-workflow-windows-amd64.zip

    5. Stop the container by running the following command:

      $ podman stop $KN_CONTAINER_ID

    6. Delete the container by running the following command:

      $ podman rm $KN_CONTAINER_ID

    7. Extract the selected Knative Workflow plugin binary file by running the following command:

      $ tar xvzf kn-workflow-linux-amd64.tar.gz

    8. Rename the Knative Workflow plugin binary file to kn-workflow by running the following command:

      $ mv kn kn-workflow

  2. Install the kn-workflow command as a plugin of the Knative cli by running the following commands:

    1. Copy the kn-workflow binary file to a directory in your PATH, such as /usr/local/bin, and ensure the file name is kn-workflow:

      $ cp path/to/downloaded/kn-workflow /usr/local/bin/kn-workflow

    2. Make the binary file executable:

      $ chmod +x /usr/local/bin/kn-workflow
Verification

  1. Run the following command to verify that the kn-workflow plugin is installed successfully:

    $ kn plugin list

  2. After installing the plugin, you can use kn-workflow to run the related subcommands.
