![]() Since this article focuses on uperf, however, we will ignore custom workloads and the other common workloads. You can also use your own workload if you are not satisfied with the workloads built in. Ripsaw is a benchmark operator for OpenShift and Kubernetes that is used to establish a performance baseline of your cluster by deploying common workloads such as: uperf, iperf3, fio, sysbench, YCSB, pgbench, smallfile, fs-drift, and hammerdb. Therefore, you need to use a tool that can query the OCP API, retrieve the following: This rule's check operates on the cluster configuration dump. The pull policy can be managed per container, using If itīecomes PullAlways, then an image registry access outage can cause key Image registry access does not prevent the pod from starting. We use PullIfNotPresent so that a loss of (oauth-server for example) to fail on an image pull for an image that isĬurrently present on the node. Enabling this feature can result in cases where loss ofĬontact to an image registry can cause a redeployed infrastructure pod OpenShift 4 master and infrastructure components areĭeployed as pods. However, turning on this admission plugin can introduce new kinds ofĬluster failure modes. Starting containers, which means valid credentials are required. When this plug-in is enabled, images are always pulled prior to Knowing the image’s name, without any authorization check against the image Image has been pulled to a node, any pod from any user can use it simply by Without this admission control policy, once an In a multi-tenant cluster users canīe assured that their private images can only be used by those who have theĬredentials to pull them. Setting admission control policy to AlwaysPullImages forces every new pod cpe:/a:redhat:openshift_container_platform:4.1.cpe:/a:redhat:openshift_container_platform:4.9.cpe:/a:redhat:openshift_container_platform:4.8.cpe:/a:redhat:openshift_container_platform:4.7.cpe:/a:redhat:openshift_container_platform:4.6.cpe:/a:redhat:openshift_container_platform:4.18.cpe:/a:redhat:openshift_container_platform:4.17.cpe:/a:redhat:openshift_container_platform:4.16.cpe:/a:redhat:openshift_container_platform:4.15.cpe:/a:redhat:openshift_container_platform:4.14.cpe:/a:redhat:openshift_container_platform:4.13.cpe:/a:redhat:openshift_container_platform:4.12.cpe:/a:redhat:openshift_container_platform:4.11.cpe:/a:redhat:openshift_container_platform:4.10.cpe:/a:redhat:openshift_container_platform_on_sdn:4.cpe:/a:redhat:openshift_container_platform_on_ovn:4.cpe:/a:redhat:openshift_container_platform_on_gcp:4.cpe:/a:redhat:openshift_container_platform_on_azure:4.cpe:/a:redhat:openshift_container_platform_on_aws:4.cpe:/o:redhat:openshift_container_platform_node:4.cpe:/a:redhat:openshift_container_platform_node_on_sdn:4.cpe:/a:redhat:openshift_container_platform_node_on_ovn:4.Of a baseline created from this guidance.
