Illumina Innovates with Rancher and Kubernetes
Rancher contains a variety of tools that aren’t included in Kubernetes to assist in your DevOps operations. Rancher can integrate with external services to help your clusters run more efficiently. Tools are divided into following categories:
Logging is helpful because it allows you to:
Rancher can integrate with Elasticsearch, splunk, kafka, syslog, and fluentd.
Logging was improved in Rancher v2.5.
Using Rancher, you can monitor the state and processes of your cluster nodes, Kubernetes components, and software deployments through integration with Prometheus, a leading open-source monitoring solution.
After monitoring is enabled, you can set up alerts and notifiers that provide the mechanism to receive them.
Notifiers are services that inform you of alert events. You can configure notifiers to send alert notifications to staff best suited to take corrective action. Notifications can be sent with Slack, email, PagerDuty, WeChat, and webhooks.
Alerts are rules that trigger those notifications. Before you can receive alerts, you must configure one or more notifier in Rancher. The scope for alerts can be set at either the cluster or project level.
Available as of v2.3
Istio is an open-source tool that makes it easier for DevOps teams to observe, control, troubleshoot, and secure the traffic within a complex network of microservices.
Rancher’s integration with Istio was improved in Rancher v2.5.
OPA Gatekeeper is an open-source project that provides integration between OPA and Kubernetes to provide policy control via admission controller webhooks. For details on how to enable Gatekeeper in Rancher, refer to the OPA Gatekeeper section.
Rancher can run a security scan to check whether Kubernetes is deployed according to security best practices as defined in the CIS Kubernetes Benchmark.
