Rancher: for Secure and Consistent Deployment of Enterprise Kubernetes Clusters

Where Can Rancher Lend a Hand?

How is Rancher better than its competitors?

  1. Rancher works 100% upstream on any cloud provider and can manage any Kubernetes service. This is very different from its competitors Pivotal or RedHat with its multiple benefits.
  2. One Rancher cluster has the ability to manage thousands of Kubernetes clusters. Since deployment, Rancher makes the installation process more powerful by involving software from the CNCF and other leaders in the open-source IT community.
  3. Being open-source, Rancher has millions of users giving their feedback on services and thousands of developers continuously fixing and improving it.
  4. Other community-related advantages of using Ranchers include continuous monitoring and logging using Fluentd, Kibana, Elasticsearch, and Grafana.

How can a private enterprise benefit from using Rancher?

  • Rancher deploys and unites the production-grade Kubernetes clusters from the datacenter with central authentication, access control, and usability. It streamlines cluster deployment on private bare-metal data centers other than public clouds and provides security using global security policies. Using Helm or the Rancher AppCatalog to deploy and manage applications maintains multi-cluster consistency.
  • The centralized App Catalog lets the user leverage Helm for multi-cluster deployment or popular applications from the Rancher ecosystem with custom-built applications as cloud-native libraries.
  • Rancher provides consistent security policies by directly enabling the encryption provider, the configuration of audit logging, and rate-limiting. It is compliant with the best CIS benchmark practices. It allows the deployment of secure clusters using cluster templates. It also supports air-gapped environments and to build Enterprise Kubernetes Platform.
  • Rancher helps in centrally configuring security policies, auditing logs, and monitoring performance. Access can be controlled by connecting them to the internal identity provider such as Active Directory, LDAP, or Okta in On-Prem Clusters.
  • Rancher helps the DevOps in transitioning more easily by using friendly tools such as Jenkins, Gitlab, and Codefresh to build CI/CD pipelines
  • Cluster Templates. Most businesses that manage multiple clusters at any time, security is of crucial importance. Cluster templates help in reducing the risk by enabling the reinforcement of consistent cluster configurations within the infrastructure. Other advantages of a cluster template are:
  • Operators are able to create, save, and reuse Kubernetes configurations across all of their cluster deployments.
  • Administrators are able to enable configuration enforcement, and hence eliminate configuration drift or improper misconfigurations which impose more security risks with more number of clusters created.
  • Administrators can scan existing clusters using tools and identify insecure cluster settings. They can also report the same to facilitate correction.
  • Service Mesh Integration. Rancher includes the premium installation and configuration of Istio is a popular service mesh that eliminates the specific code writing to activate key Kubernetes features such as fault tolerance, canary rollouts, A/B testing, monitoring, and metrics, tracing and observability, observability authentication and authorization.
  • For Yobitel and it’s customers, Rancher provides outstanding support in providing cluster support for application integration, continuous monitoring, and in-built CNI & Service mesh workloads.

Creating a Private Container Library or Marketplace

Create a new GitHub repository:

  1. In the upper-right corner of your GitHub page, use the + drop-down menu, and select New repository.
  2. Type a short, memorable name for your repository. For example, “rancher-catalog”.
  3. Optionally, add a description of your repository. For example, “My first repository on GitHub.”
  4. Choose to make the repository either public or private. Public repositories are visible to the public, while private repositories are only accessible to you, and people you choose to share them with.
  5. Select Initialize this repository with a README.
  6. Click Create repository.

Hosting Private Catalog in Ranchers

  • Making the deployment of your developed services more productive and repeatable.
  • Publishing the own developed services for your consumers
  • Managing the life cycle of your deployed services
  • Controlling the updates of your deployed services
  • Sharing the released services between teams

The different kinds of Catalog Repos

  • Global: This catalog repo is available to all various Rancher environments.
  • Environment: This catalog repo is only available to the current Rancher environment.
  • Unique name
  • Repository URL:
  • Git-based catalog URL
  • Helm Charts server URL

Add a Private Git-based or Helm chart based Repository

  1. From the Global view, choose Tools > Catalogs in the navigation bar. In versions prior to v2.2.0, you can select Catalogs directly in the navigation bar.
  2. Click Add Catalog.
  3. Complete the form and click Create.

Launch and install the Application:

  1. Launch > All Catalogs > choose your private Catalog
  1. Install the application: Select the application from the custom repository > View Details > Launch
  2. Once the application is deployed successfully, the ports will appear on the screen with which application can be exposed in a public environment.

Summary

  • It has an easy to use, straightforward interface for management of applications.
  • It provides a selection of multiple container orchestration frameworks Kubernetes and Docker Swarm which lets the DevOps teams choose the best and also maintain a single management experience.
  • It implemented a cloud-agnostic infrastructure services layer that works for all public or private clouds. It provides a uniform, consistent storage service available on all computing resources.
  • It allows higher visibility, better policy management, and authorizes more control of containers and infrastructure across different teams.
  • It enables better deployment reliability, supports software upgrades, and improves resource utilization.
