Announcing Mesos Support in Rancher

Share

[twitter_launchvfI
am excited to announce that Rancher officially supports Mesos, one of
the most popular distributed cluster managers on the market today. Mesos
is able to manage a large number of computing hosts and schedule
computing jobs to these hosts according to their CPU, memory, and
storage needs. ]

[But Mesos is much more than a distributed resource manager and
scheduler. In the past few years, the
][Mesos
community]
[ has
developed a rich set of frameworks to automate the deployment and
operations of large-scale distributed applications such as Hadoop,
Elasticsearch, Spark, and Kafka. With Mesos support, Rancher greatly
simplifies the effort required to run Mesos clusters and Mesos
frameworks.]

[It is a straightforward, 3-step process to set up and run Mesos
clusters on Rancher:]

  • Step 1: Create a Mesos environment [Starting from the
    v1.1.0-dev2 open source release, you are able to create Mesos
    environments in addition to Kubernetes and Swarm
    environments]

  • Step 2: Add hosts to the Mesos environment [Once you create a
    Mesos environment, you can add hosts into a Mesos cluster from a
    variety of infrastructure providers including public clouds, bare
    metal servers, and virtualization
    clusters:]

  • Step 3: Deploy Mesos frameworks [Once the Mesos master and slave
    agents are up, you can select to deploy any number of Mesos
    frameworks from the Rancher Catalog. You can expect the number of
    Mesos frameworks in the Rancher catalog to grow as the Rancher
    community continues to contribute.]

[We’ve put together a short walkthrough of this process, along with a
demonstration of the automated upgrade
capabilities.]

[By using Mesos and Mesos frameworks on Rancher, you benefit from all
the capabilities Rancher brings to run containers in
production:]

  1. [Rancher automates the deployment and upgrade of the Mesos cluster
    itself, which includes the Zookeeper cluster, Mesos master cluster,
    and Mesos slave agents. Rancher deploys Zookeeper, Mesos master, and
    Mesos slave as containers, monitors their health, and coordinates
    the upgrade of a running Mesos cluster without impacting the
    workload.]
  2. [Rancher provides a catalog of Mesos frameworks and automates the
    deployment and upgrade of these Mesos frameworks. Rancher deploys
    each of these Mesos frameworks as containers. The Mesos framework
    then interacts with Mesos master and Zookeeper to schedule workload.
    Rancher coordinates the upgrade of Mesos frameworks as new versions
    become available.]
  3. [Rancher enables users to create multiple Mesos clusters and enforce
    advanced Role Based Access Control (RBAC) policies on these
    clusters. Users can grant and restrict access to their Mesos
    clusters to other users.]
  4. [Rancher allows users to create hosts from any infrastructure
    provider, including public clouds, private clouds, virtualization
    clusters, and bare metal servers.]
  5. [Rancher implements software-defined networking which enables
    containers running on different hosts and clouds to communicate with
    each other.]
  6. [Rancher implements persistent storage services which enables users
    to run stateful applications using Mesos
    frameworks.]
  7. [Rancher provides load balancer service and DNS integration for
    Mesos users.]
  8. [Rancher enables development teams in large organizations to have
    their choice of container orchestration and scheduling technologies
    by supporting all popular platforms including Kubernetes, Docker
    Swarm, and Mesos. In addition, Rancher enables applications and
    services hosted in these different platforms to interoperate with
    each other.]

[We previewed some of these capabilities with EMC earlier this year,
showcasing EMC’s RackHD,
ScaleIO, and
REX-Ray
products:]

  • [Create a Mesos environment on Rancher]
  • [Use RackHDto add a
    number of bare metal hosts into the Mesos
    cluster]
  • [Deploy ScaleIOas
    persistent storage system for the Mesos
    cluster]
  • [Deploy a REX-Ray driver and
    use that to access ScaleIO]
  • [Deploy a custom application on the Mesos cluster from the Rancher
    catalog]
  • [Use Rancher to provision additional hosts from a public cloud,
    leverage Rancher SDN to connect containers on bare metal hosts and
    the public cloud, and then scale the application up to run on more
    hosts.]

– it is remarkable what Rancher, Mesos, RackHD, ScaleIO and REX-Ray can
accomplish together.]
