Migrating Applications from Rancher 1.6 to Rancher 2.0: Walkthrough Video

Rancher 2.0 was rearchitected with the goal of providing a complete multi-cluster management solution for Kubernetes and Docker containers. Because of these changes, there is no direct upgrade path from Rancher 1.6 to Rancher 2.x. This demonstration video guides users through migrating Rancher 1.6 applications to Rancher 2.x. There are several other important resources to utilize: October Online Meetup: Migrating from Rancher 1.6 to Rancher 2.0 In our October Online Meetup, we will dive into how to transition various aspects of Rancher 1.

September Online Meetup: Understanding Storage Options for Kubernetes using Rancher 2.0 and Project Longhorn

September Online Meetup: Understanding Storage Options for Kubernetes using Rancher 2.0 and Project Longhorn

Although more and more companies choose to containerize their applications and to use Kubernetes to orchestrate their containers, they continue to face a common challenge: how to preserve application data even after a container closes. Without the ability to persist data, containers might seem to have limited use in many workloads, especially in stateful applications and database architectures. Fortunately many solutions exist. Join Rancher Labs as we do a deep dive into storage solutions for Docker containers and Kubernetes and discuss best practices for a wide variety of storage use cases. Read More…

From Cattle to K8s - How to Load Balance Your Services in Rancher 2.0

If you are running a user-facing application drawing a lot of traffic, the goal is always to serve user requests efficiently without having any of your users get a server busy! sign. The typical solution is to horizontally scale your deployment so that there are multiple application containers ready to serve the user requests. This technique, however, needs a solid routing capability that efficiently distributes the traffic across your multiple servers. Read More…

From Cattle to K8s - Scheduling Workloads in Rancher 2.0

An important and complex aspect of container orchestration is scheduling the application containers. Appropriate placement of containers onto the shared infrastructure resources that are available is the key to achieve maximum performance at optimum compute resource usage. Cattle, which is the default orchestration engine for Rancher 1.6, provided various scheduling abilities to effectively place services, as documented here. With the release of the 2.0 version based on Kubernetes, Rancher now utilizes native Kubernetes scheduling. Read More…

From Cattle to K8s - Application Healthchecks in Rancher 2.0

When your application is user-facing, ensuring continuous availability and minimal downtime is a challenge. Hence, monitoring the health of the application is essential to avoid any outages. HealthChecks in Rancher 1.6 Cattle provided the ability to add HTTP or TCP healthchecks for the deployed services in Rancher 1.6. Healthcheck support is provided by Rancher’s own healthcheck microservice. You can read more about it here. In brief, a Cattle user can add a TCP healthcheck to a service. Read More…

From Cattle to K8s - How to Publicly Expose Your Services in Rancher 2.0

Real world applications deployed using containers usually need to allow outside traffic to be routed to the application containers. Standard ways for providing external access include exposing public ports on the nodes where the application is deployed or placing a load balancer in front of the application containers. Cattle users on Rancher 1.6 are familiar with port mapping to expose services. In this article, we will explore various options for exposing your Kubernetes workload publicly in Rancher 2.

Migrating from Rancher 1.6 to Rancher 2.0 - A Short Checklist

Rancher 1.6 is a widely used container orchestration platform that runs and manages Docker and Kubernetes in production. Cattle is the base orchestration engine for Rancher 1.6 that is being used by many opensource and enterprise setups. With the release of Rancher 2.0, we shifted from Cattle as the base orchestration platform to Kubernetes. As aptly noted here, Rancher 2.0 aims at helping users align with the Kubernetes Everywhere reality of the infrastructure and cloud domain. Read More…

Building a CI/CD Pipeline with Kubernetes using Auto Devops, Rancher, and Gitlab

This blog coincides with the Rancher Labs Online Meetup August 2018 covering Continuous Integration/Continuous Delivery (CI/CD). This topic is becoming increasingly important in a world where services are getting small, with frequent updates. It allows for companies to completely automate the building, testing and deployment of code to ensure that it is done in a consistent, repeatable way. There are several different CI/CD tools available and there are a bunch of them that will integrate with Kubernetes natively. Read More…
