with a given cluster. Internal Kubernetes components use log library to log data; kubectl (the command line interface) can be used to fetch log data from containers. This data can be fed to an ELK (Elasticsearch KUBERNETES WITH RANCHER As we add the details for the hosts, the command to register the host with Rancher is modified. Copy this command and log into a host other than Rancher master on which you want want to setup your Kubernetes cluster: Once you run above command on a new machine, the host(s) tries to contact the Rancher server with the key. The server then verifies the key and registers the

The commands listed below will remove the DOS-type line endings and create the necessary secret. 11 SAP Data Intelligence reconfiguration of DI 3.3, for example to enable backup. If you forgot to note it down, the following command will list the service port: $ kubectl -n sap-slcbridge get svc 12 SAP Data Intelligence 3 on Rancher Manager with a valid sub- scription. SUSE Linux Enterprise Server 15 SP4 can be updated on the command line using zypper : $ sudo zypper ref -s $ sudo zypper lu $ sudo zypper patch Other methods for

A common error is a network or firewall issue preventing the node NOTE: Although enterprise-hub.juniper.net is not configured to respond to pings, we can use the ping command to check domain name resolution. In this example, the domain name is not resolving. Check the domain c. If some pods remain down, debug the deployment as you normally do.

By leveraging their existing relationships with global enterprises, Red Hat has been the TKG Management Cluster and application clusters happens through the installer GUI or via command-line directives that use a YAML configuration file. Clusters can run on vSphere, Amazon, Microsoft logs from applications, infrastructure and audit logs. This information can be queried via the oc command or in the Kibana dashboard. OpenShift logging is based in the EFK stack (Elasticsearch, Fluentd
