To configure Cilium in the management cluster interface of the Shturval platform: in the side menu, open the Services and repositories section; go to the Installed services page. find the Cluster Network Management Module. To configure Cilium in the client cluster interface of the Shturval platform: in the side menu, open the Services and repositories section; go to the Installed services page.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/kube-vip/Tue, 06 Oct 2020 08:49:31 +0000https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/kube-vip/In the Shturval platform, the Virtual IP Address Management Module (Kube VIP) includes two components: Service configuration component (shturval-vip-provider). It automatically assigns IP addresses to Services of type LoadBalancer. The controller shturval-vip-provider, when creating a Service with type LoadBalancer in the cluster, allocates and assigns an IP address from the configured CIDR or IP address range. The dedicated IP address is specified in the annotation and the loadBalancerIP parameter of the service.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/ingressnginx/Tue, 06 Oct 2020 08:49:31 +0000https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/ingressnginx/In this section you can configure the routing of external connections to the cluster (Ingress Controller). It provides management and routing of incoming traffic from outside to various services and applications deployed in containers. To configure Ingress Controller in the cluster interface of the Shturval platform, go to the Installed services page of the Services and repositories section. If the module is not displayed, go to the available charts, on the “shturval” tab, find the “shturval-ingress-controller” chart and click “Install”.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/multus/Tue, 06 Oct 2020 08:49:31 +0000https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/multus/The module for connecting multiple network interfaces to modules in Kubernetes (Multus CNI) is a meta-plugin that calls other CNI plugins, such as Flannel, Weave, Calico, Cilium, Macvlan. Using the module, it is possible to create a pod with several network interfaces, for example, eth0, net0, net1. By default, the module is not installed on clusters. To install the module, in the side menu of the cluster graphical interface, open the Services and repositories section and go to the Available charts page.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/ipam/Tue, 06 Oct 2020 08:49:31 +0000https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/ipam/The IP address assignment module on interfaces created by Multus (Whereabouts) is responsible for IP address management (IPAM) for the network interfaces of the pods. The module allows you to: assign IP addresses within a range in CIDR notation (without the need to use a DHCP server); if necessary, add IP addresses to the list of exclusions of range addresses. When an IP address is assigned to a pod, the pod tracks that IP address in the data store throughout the life of the pod.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/nodelocaldns/Mon, 16 Nov 2020 13:59:39 +0100https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/nodelocaldns/In the Shturval platform, the local DNS management module provides the system for resolving DNS names within the cluster. You can manage records that contain the mapping between domain names and IP addresses of objects in your cluster. To do this, in the platform’s graphical interface: In the cluster graphical interface, in the side menu, open the Services and repositories section and go to the Installed services page. Find the local DNS control module (shturval-caching-dns) and open the module management page.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/sriov-operator/Tue, 06 Oct 2020 08:49:31 +0000https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/sriov-operator/SR-IOV (Single Root I/O Virtualization) is a technology that allows you to divide a physical I/O device into many virtual ones. The SR-IOV operator uses Kubernetes CRDs and Operator SDK to manage SriovNetwork resources and SriovNetworkNodePolicy. The SR-IOV operator is responsible for automatically deploying and configuring the SR-IOV CNI plugin and device plugin on Worker nodes in the cluster, initializing supported SR-IOV network card (NIC) types on the nodes, generating a CR NetworkAttachmentDefinition for the SR-IOV CNI plugin, maintaining operation in a virtualized Kubernetes deployment, detecting VFs connected to the virtual machine (VM), as well as the ability to associate VF with SriovNetworks by selecting the corresponding PciAddress as RootDevice in SriovNetworkNodePolicy.https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/coreha/Tue, 06 Oct 2020 08:49:31 +0000https://docs.shturval.tech/2.13/en/cluster-admin/ssc/general/networks/coreha/The module for searching for nodes with running hostport services (shturval-coreha) is designed for dynamically adding backends to HAProxy. The service is required if you are using an external balancer for Ingress. The module is not critical for the operation of the platform; by default, it is installed in clusters in a disabled state. To enable, go to the Services and repositories section and open the Installed services page. Find Module for searching for nodes with running hostport services and change the value of the switch.
