Chapter 11. Caching images for faster workspace start To improve the start time performance of CodeReady Workspaces workspaces, use the Image Puller, a CodeReady Workspaces-agnostic component that can be used to pre-pull images for OpenShift clusters. The Image Puller is an additional OpenShift deployment which creates a DaemonSet that can be configured to pre-pull relevant CodeReady Workspaces workspace images on each node. These images would already be available when a CodeReady Workspaces workspace starts, therefore improving the workspace start time. The Image Puller provides the following parameters for configuration. Table 11.1. Image Puller parameters Parameter Usage Default CACHING_INTERVAL_HOURS DaemonSets health checks interval in hours "1" CACHING_MEMORY_REQUEST The memory request for each cached image when the puller is running. See Section 11.2, "Defining the memory parameters for the Image Puller" . 10Mi CACHING_MEMORY_LIMIT The memory limit for each cached image when the puller is running. See Section 11.2, "Defining the memory parameters for the Image Puller" . 20Mi CACHING_CPU_REQUEST The processor request for each cached image when the puller is running .05 or 50 millicores CACHING_CPU_LIMIT The processor limit for each cached image when the puller is running .2 or 200 millicores DAEMONSET_NAME Name of DaemonSet to create kubernetes-image-puller DEPLOYMENT_NAME Name of the Deployment to create kubernetes-image-puller NAMESPACE OpenShift project containing DaemonSet to create k8s-image-puller IMAGES Semicolon separated list of images to pull, in the format <name1> = <image1> ; <name2> = <image2> See Section 11.1, "Defining the list of images to pull" .

Those secrets need to be in the image puller's namespace and a cluster administrator must create them.

Defining the list of images to pull The Image Puller can pre-pull most images, including scratch images such as che-machine-exec . However, images that mount volumes in the Dockerfile, such as traefik , are not supported for pre-pulling on OpenShift 3.11. Pre-pulling images involved in workspace startup will reduce workspace start times. For example: Che-Theia broker images plug-in sidecar images Prerequisites The curl tool is available. See curl homepage . The jq tool is available. See jq homepage . The yq tool is available. See yq homepage . Procedure Gather a list of relevant container images for the OpenShift platform: Example 11.1. Getting the list of all images for CodeReady Workspaces 2.15 Retain the images involved on the workspace startup phase: eap machineexec mongodb pluginbroker plugin- stacks theia ubi-minimal Exclude from the list the container images not supported by the target platform. For AMD64 and Intel 64 (x86_64). Example 11.2. Image list for AMD64 and Intel 64 (x86_64) For IBM Z and IBM Power, exclude dotnet . Example 11.3. Image list for IBM Z and IBM Power: excluding dotnet Determine images from the list for pre-pulling. For faster workspace startup times, consider pre-pulling the workspace-related images: theia-rhel8 theia-endpoint-rhel8 pluginbroker-artifacts-rhel8 pluginbroker-metadata-rhel8 stacks-*-rhel8 plugin-*-rhel8 The list of stacks images: Container images - Stacks The list of plug-in images: Container images - Plug-ins Additional resources Section 11.2, "Defining the memory parameters for the Image Puller" . Section 11.4, "Installing Image Puller on OpenShift 4 using OperatorHub" Section 11.5, "Installing Image Puller on OpenShift using OpenShift templates" 11.2. Defining the memory parameters for the Image Puller Define the memory requests and limits parameters to ensure pulled containers and the platform have enough memory to run. Prerequisites Section 11.1, "Defining the list of images to pull" Procedure To define the minimal value for CACHING_MEMORY_REQUEST or CACHING_MEMORY_LIMIT , consider the necessary amount of memory required to run each of the container images to pull. To define the maximal value for CACHING_MEMORY_REQUEST or CACHING_MEMORY_LIMIT , consider the total memory allocated to the DaemonSet Pods in the cluster: Pulling 5 images on 20 nodes, with a container memory limit of 20Mi requires 2000Mi of memory.

Red Hat official build benefits from extra testing and validation provided by Red Hat. Enabling the use of KubernetesImagePuller in Operator Hub during CodeReady Workspaces installation, sets the Community supported version for use. Community build Red Hat official build Default images The CodeReady Workspaces Operator populates the .spec.imagePuller.spec.images field with default images used for workspace startup (Theia images, plug-in broker images, sidecar plug-in images), provided that no images were added to this field before creating the CheCluster Custom Resource. The CodeReady Workspaces Operator updates the default images in the .spec.imagePuller.spec.images field after every rollout update of CodeReady Workspaces. However, if images were added to the .spec.imagePuller.spec.images field before creating the CheCluster Custom Resource, the CodeReady Workspaces Operator will not add default images. If user-provided images are added to the .spec.imagePuller.spec.images field after creating the CheCluster Custom Resource, the CodeReady Workspaces Operator will still update default images on subsequent CodeReady Workspaces rollout updates. Non-default images remain unchanged in the .spec.imagePuller.spec.images field after rollout updates. Verification OpenShift creates a kubernetes-image-puller-operator Subscription.
