Install the MicroShift low latency RPM package

When you install MicroShift, the low latency RPM package is not installed by default. You can install the low latency RPM as an optional package.

Prerequisites

  • You installed the MicroShift RPM.

  • You configured workload partitioning for MicroShift.

Procedure

  • Install the low latency RPM package by running the following command:

    $ sudo dnf install -y microshift-low-latency
    Tip

    Wait to restart the host until after activating your TuneD profile. Restarting the host restarts MicroShift and CRI-O, which applies the low latency manifests and activates the TuneD profile.
Next steps

  1. Configure the kubelet parameter for low latency in the MicroShift config.yaml.

  2. Tune your operating system, for example, configure and activate a TuneD profile.

  3. Optional: Configure automatic activation of your TuneD profile.

  4. Optional: If you are using the x86_64 architecture, install Red Hat Enterprise Linux for Real Time (real-time kernel).

  5. Prepare your workloads for low latency.
