Installing Rancher - From Single Container to High Availability

September 7, 2017

Any time an organization, team or developer adopts a new platform, there are certain challenges during the setup and configuration process. Often installations have to be restarted from scratch and workloads are lost. This leaves adopters apprehensive about moving forward with new technologies. The cost, risk and effort are too great in the business of today. With Rancher, we’ve established a clear installation and upgrade path so no work is thrown away. Facilitating a smooth upgrade path is key to mitigating against risk and increasing costs. Read more

5 Keys to Running Workloads Resiliently with Rancher and Docker – Part 2

September 14, 2016

In Part 1: Rancher Server HA, we looked into setting up Rancher Server in HA mode to secure it against failure. There now exists a degree of engineering in our system on top of which we can iterate. So what now? In this installment, we’ll look towards building better service resiliency with Rancher Health Checks and Load Balancing.

Since the Rancher documentation for Health Checks and Load Balancing are extremely detailed, Part 2 will focus on illustrating how they work, so we can become familiar with the nuances of running services in Rancher. A person tasked with supporting the system might have several questions. For example, how does Rancher know a container is down? How is this scenario different from a Health Check? What component is responsible for operating the health checks? How does networking work with Health Checks? Read more

5 Keys to Running Workloads Resiliently with Rancher and Docker – Part 1

August 4, 2016

Containers and orchestration frameworks like Rancher will soon allow every organization to have access to efficient cluster management.

This brave new world frees operations from managing application configuration and allows development to focus on writing code; containers abstract complex dependency requirements, which enables ops to deploy immutable containerized applications and allows devs a consistent runtime for their code.

If the benefits are so clear, then why do companies with existing infrastructure practices not switch? One of the key issues is risk. The risk of new unknowns brought by an untested technology, the risk of inexperience operating a new stack, and the risk of downtime impacting the brand.
