Illumina Innovates with Rancher and Kubernetes
Deploy a PHP application on Kubernetes with custom OPcache and PHP-FPM configurations to improve performance. You’ll use Rancher to deploy a PHP application using custom environment variables to dynamically configure OPcache and PHP-FPM.
Introduction The demands of modern software development combined with complexities of deploying to varied infrastructure can make creating applications a tedious process. As applications grow in size and scope, and development teams become more distributed and diverse, the overall process required to produce and release software quickly and consistently becomes more difficult.
To address these issues, teams began exploring new strategies to automate their build, test, and release processes to help deploy new changes to production faster.
Introduction As Kubernetes becomes more and more prevalent as a container orchestration system, it is important to properly architect your Kubernetes clusters to be highly available. This guide covers some of the options that are available for deploying highly available clusters, as well as an example of deploying a highly available cluster.
In this article, we will be using the Rancher Kubernetes Engine (RKE) as the installation tool for our cluster.
In this tutorial, we walk through using Rancher to deploy a Redis cluster within Kubernetes. After following the steps in this article, you will have a fully functional installation of Redis, and you will have tested the cluster's availability under failure conditions.
This article analyzes the recent CNCF article, '9 Kubernetes Security Best Practices Everyone Must Follow' and discusses how Rancher, RKE, and RancherOS satisfy these by default. I also discuss the Rancher Hardening Guide, which covers 101 more security changes that will secure your Kubernetes clusters.
This tutorial walks through using Rancher to deploy Elasticsearch into a Kubernetes cluster. At the end of this article, you will have a fully functional 2-node Elasticsearch cluster, complete with sample data and examples of successful queries.
In this tutorial, we will walk through using Rancher to deploy and scale Jenkins on top of Kubernetes. By following steps from this article, you will create a fully functional installation of Jenkins with a master-agent architecture that we use to test real build jobs.
In this article we'll walk through using Rancher to deploy and manage JFrog Artifactory on a Kubernetes cluster. When you have finished reading this article, you will have a fully functional installation of, and you can use the same steps to install the OSS or commercial version of Artifactory in any other Kubernetes cluster.
When traffic increases, we need to have a way to scale our application to keep up with user demand. With Kubernetes multi-cluster management through Rancher, scaling has never been easier and more efficient. Read here about scaling Kubernetes and the challenges you might be facing when managing a hybrid cloud environment.
This blog covers building a CI/CD Pipeline using the hosted GitLab.com solution. The Kubernetes integrations that are covered are generic and should work with any CI/CD provider that interface directly to Kubernetes using a service account. Tools used are Auto Devops, Rancher, and Gitlab.
One of the nicer features of Kubernetes is the ability to code and configure autoscale on your running services. Without autoscaling, it's difficult to accommodate deployment scaling and meet SLAs. This article will show you how to autoscale your services on Kubernetes using Horizontal Pod Autoscale.
In this blog series, we will try to explore how various features supported by Rancher 1.6 using Cattle can be mapped to their equivalents in the Kubernetes world using Rancher 2.0. Read part 1 here.
Service mesh is a new technology stack aimed at solving the connectivity problem between cloud native applications. Read an overview at the Rancher blog.
Objective: In this article, we will walk through running a distributed, production-quality database setup managed by Rancher and characterized by stable persistence. We will use Stateful Sets with a Kubernetes cluster in Rancher for the purpose of deploying a stateful distributed Cassandra database.
Pre-requisites: We assume that you have a Kubernetes cluster provisioned with a cloud provider. Consult the Rancher resource if you would like to create a K8s cluster in Amazon EC2 using Rancher 2.
Recently, we announced our second milestone release of Rancher 2.0 Tech Preview 2. This includes the possibility to add custom nodes (nodes that are already provisioned with a Linux operating system and Docker) by running a generated docker run command to launch the rancher/agent container, or by connecting over SSH to that node. In this post, we will explore how we can automate the generation of the command to add nodes using the docker runcommand.
It’s finally here: the Rancher you’ve all been waiting for. Rancher 2.0 is now in preview mode and available to deploy! Rancher 2.0 brings us a whole new Kubernetes-based structure, with new features like platform-wide multi-select, adoption of existing Kubernetes clusters, and much, much more. If you’re looking to dive in with Rancher 2.0, you’ve come to the right place.
Assumptions You have a Linux host with at least 4 GB of RAM.
[Recently Rancher introduced the Rancher catalog, an awesome feature that enables Rancher users to one-click deploy common applications and complex services from catalog templates on your infrastructure, and Rancher will take care of creating and orchestrating the Docker containers for you.] Rancher catalog offers a wide variety of applications in its out of the box catalog, including glusterfs or elasticsearch, as well as supporting private catalogs. Today I am going to introduce a new catalog template I developed for deploying a MongoDB replicaset, and show you how I built it.
Last week Ivan Mikushin discussed adding system services to RancherOS using Docker Compose. Today I want to show you an exmaple of how to deploy Linux Dash as a system service. Linux Dash is a simple, low overhead, and web supported monitoring tool for Linux, you can read more about Linux Dash here. In this post i will add Linux Dash as a system service to RancherOS version 0.3.0 which allows users to add system services using rancherctl command.
[Since the availability of Rancher’s Beta release a few weeks ago, I’ve been pretty excited about the new scheduling and service discovery capabilities in the platform. To help people understand the impact of these capabilities, today I’m going to show how to use these features to deploy a fully clustered and HA implementation of a Node.js application. I’m going to use ][Let’s Chat as our example application, It is an excellent ][open-source, Slack-like team chat application.
I have already talked about several ways to monitor docker containers and also using Prometheus to monitor Rancher deployments. However, until now it has been a manual process of launching monitoring agents on our various hosts. With the release of the Rancher beta with scheduling and support for Docker compose we can begin to make monitoring a lot more automated. In today’s post we will look at using Rancher’s new \“Rancher compose\” tool to bring up our deployment with a single command, using scheduling to make sure we have a monitoring agent running on every host, and using labels to isolate and present our metrics.
Hi, I’m Craig Jellick, an engineer here at Rancher Labs, and I wanted to walk you through a new set of features that we recently added to Rancher as we prepared for beta. Internally, we call it our \“Native Docker Management\” functionality, and it is incredibly core to our mission here at Rancher. When we built Rancher, we explicitly didn’t want to wrap Docker’s APIs with a new management layer. A number of existing tools already take that approach, and while it is an effective way of building a controlled system, we really loved the experience using the Docker CLI and API, and were sure that it would just keep getting better over time.
In my last post I showed you how to deploy a Highly Available Wordpress installation using Rancher Services, a Gluster cluster for distributed storage, and a database cluster based on Percona XtraDB Cluster. Now I’m going one step further and we are setting Gluster and PXC clusters using Rancher Services too. And now we are using new service features available on the beta Rancher release like DNS service discovery and Label Scheduling.
GlusterFS is a scalable, highly available, and distributed network file system widely used for applications that need shared storage including cloud computing, media streaming, content delivery networks, and web cluster solutions. High availability is ensured by the fact that storage data is redundant, so in case one node fails another will cover it without service interruption. In this post I’ll show you how to create a GlusterFS cluster for Docker that you can use to store your containers data.
In this article, Rancher compares seven Docker monitoring options and goes over some of the common tools used to monitor containers. Visit us to learn more.
