Live migration of virtual machines is now supported by RancherVM. Learn how to setup shared storage and run VM migration to different hosts.
Recently, I moved to New York City. As a new resident, I decided to take part in the NYC DeveloperWeek hackathon, where our team won the NetApp challenge. In this post, I’ll walk through the product we put together, and share how we built a CI/CD pipeline for quick, iterative product development under tight constraints.
The Problem: Have you ever lived or worked in a building where it’s a pain to configure the buzzer to forward to multiple roommates or coworkers?
Introduction If you have been working with Docker for any length of time, you probably already know that shared volumes and data access across hosts is a tough problem. While the Docker ecosystem is maturing, implementing persistent storage across environments still seems to be a problem for most folks. Luckily, Rancher has been working on this problem and come up with a unique solution that addresses most of these issues.
We just released Convoy v0.3 last week, and I’m excited to announce that it now supports Amazon Elastic Block Store (EBS) as a Convoy driver. With this release you can now create persistent Docker volumes on AWS, backed with all the performance and features of EBS. With this new feature, when users create a Convoy volume using the EBS driver, Convoy will create an EBS volume, attach it to the current running instance, and then assign it to the Docker container.
The latest release of Docker Engine now supports volume plugins, which allow users to extend Docker capabilities by adding solutions that can create and manage data volumes for containers that need to manage and operate on persistent datasets.This is especially important for databases, and addresses one of the key limitations in Docker. Recently at Rancher we released Convoy, an open-source Docker volume driver that makes it simple to snapshot, backup, restore Docker volumes across clouds.
Note: Rancher has come a long way since this was first published in June 2015. We’ve revised this post (as of August 2016) to reflect the updates in our enterprise container management service. Read on for the updated tutorial!
Rancher supports multiple orchestration engines for its managed environments, including Kubernetes, Mesos, Docker Swarm, and Cattle (the default Rancher managed environment). The Cattle environment is rich with features like stacks, services, and load balancing, and in this post, we’ll highlight common uses for these features.
Last week we introduced our new project, Rancher.io, at AWS Re:Invent, and it was amazing. We’d been working on the software for months, talking with good friends, old customers and former colleagues about what we were building and wondering how it would be received by users. We were anxious to share it with new people and eager to get their feedback. We were also really nervous. Four of us flew out to Vegas, set up our little booth, tested our demos and organized our piles of stickers and t-shirts.
