Mirantis Releases Kubernetes Distribution and Updated Mirantis OpenStack

The post Mirantis Releases Kubernetes Distribution and Updated Mirantis OpenStack appeared first on Mirantis | Pure Play Open Cloud.
Mirantis Cloud Platform 1.0 is a distribution of OpenStack and Kubernetes that can orchestrate VMs, Containers and Bare Metal

SUNNYVALE, CA – April 19, 2017 – Mirantis, the managed open cloud company, today announced availability of a commercially-supported distribution of OpenStack and Kubernetes, delivered in a single, integrated package, and with a unique build-operate-transfer delivery model.

“Today, infrastructure consumption patterns are defined by the public cloud, where everything is API driven, managed and continuously delivered. Mirantis OpenStack, which featured Fuel as an installer, was the easiest OpenStack distribution to deploy, but every new version required a forklift upgrade,” said Boris Renski, Mirantis co-founder and CMO. “Mirantis Cloud Platform departs from the traditional installer-centric architecture and towards an operations-centric architecture, continuously delivered by either Mirantis or the customers’ DevOps team with zero downtime. Updates no longer happen once every 6-12 months, but are introduced in minor increments on a weekly basis. In the next five to ten years, all vendors in the space will either find a way to adapt to this pattern or they will disappear.”

Along with launching Mirantis Cloud Platform (MCP) 1.0, Mirantis is also first to introduce a unique delivery model for the platform. Unlike traditional vendors that sell software subscriptions, Mirantis will onboard customers to MCP through a build-operate-transfer delivery model. The company will operate an open cloud platform for customers for a period of at least twelve months with up to four nines SLA prior to off boarding the operational burden to customer’s team, if desired. The delivery model ensures that not just the software, but also the customer&8217;s team and process are aligned with DevOps best practices.

Unlike any other solution in the industry, customers onboarded to MCP have an option to completely transfer the platform under their own management. Everything in MCP is based on popular open standards with no lock-in, making it possible for customers to break ties with Mirantis and run the platform independently should they choose to do so.

“We are happy to see a growing number of vendors embrace Kubernetes and launch a commercially supported offering based on the technology,” said Allan Naim from the Kubernetes and Container Engine Product Team.

“As the industry embraces composable, open infrastructure, the &8220;LAMP stack of cloud&8221; is emerging, made up of OpenStack, Kubernetes, and other key open technologies,” said Mark Collier, chief operating officer, OpenStack Foundation. “Mirantis Cloud Platform presents a new vision for the OpenStack distribution, one that embraces diverse compute, storage and networking technologies continuously rather than via major upgrades on six-month cycles.&8221;

Specifically, Mirantis Cloud Platform 1.0 is:

Open Cloud Software — providing a single platform to orchestrate VMs, containers and bare metal compute resources by:

Expanding Mirantis OpenStack to include Kubernetes for container orchestration.
Complementing the virtual compute stacks with best-in-class open source software defined networking (SDN), specifically Mirantis OpenContrail for VMs and bare metal, and Calico for containers.
Featuring Ceph, the most popular open source software defined storage (SDS), for both Kubernetes and OpenStack.

DriveTrain &8212; Mirantis DriveTrain sets the foundation for DevOps style lifecycle management of the open cloud software stack by enabling continuous integration, continuous testing and continuous delivery through a CI/ CD pipeline. DriveTrain enables:

Increased Day 1 flexibility to customize the reference architecture and configurations during initial software installation.
Greater ability to perform Day 2 operations such as post-deployment configuration, functionality and architecture changes.
Seamless version updates through an automated pipeline to a virtualized control plane to minimize downtime.

StackLight &8212; enables strict compliance to availability SLAs by providing continuous monitoring of the open cloud software stacks through a unified set of software services and dashboards.

StackLight avoids lock-in by including best-in-breed open source software for log management, metrics and alerts.
It includes a comprehensive DevOps portal that displays information such as StackLight visualization and DriveTrain configuration settings.
The entire Mirantis StackLight toolchain is purpose-built for MCP to enable up to 99.99% uptime service level agreements with Mirantis Managed OpenStack.

With the release of MCP, Mirantis is also announcing end-of-life for Mirantis OpenStack (MOS) and Fuel by September 2019. Mirantis will be working with all customers currently using MOS on a tailored transition plan from MOS to MCP.

How do you build 12-factor apps using Kubernetes?

The post How do you build 12-factor apps using Kubernetes? appeared first on Mirantis | Pure Play Open Cloud.
It’s said that there are 12 factors that define a cloud-native application.  It&8217;s also said that Kubernetes is designed for cloud native computing. So how do you create a 12-factor application using Kubernetes?  Let&8217;s take a look at exactly what twelve factor apps are and how they relate to Kubernetes.
What is a 12 factor application?
The Twelve Factor App is a manifesto on architectures for Software as a Service created by Heroku. The idea is that in order to be really suited to SaaS and avoid problems with software erosion — where over time an application that&8217;s not updated gets to be out of sync with the latest operating systems, security patches, and so on &8212; an app should follow these 12 principles:

Codebase
One codebase tracked in revision control, many deploys
Dependencies
Explicitly declare and isolate dependencies
Config
Store config in the environment
Backing services
Treat backing services as attached resources
Build, release, run
Strictly separate build and run stages
Processes
Execute the app as one or more stateless processes
Port binding
Export services via port binding
Concurrency
Scale out via the process model
Disposability
Maximize robustness with fast startup and graceful shutdown
Dev/prod parity
Keep development, staging, and production as similar as possible
Logs
Treat logs as event streams
Admin processes
Run admin/management tasks as one-off processes

Let&8217;s look at what all of this means in terms of Kubernetes applications.
Principle I. Codebase
Principle 1 of a 12 Factor App is “One codebase tracked in revision control, many deploys”.
For Kubernetes applications, this principle is actually embedded in the nature of container orchestration itself.  Typically, you create your code using a source control repository such as a git repo, then store specific versions of your images in the Docker Hub. When you define the containers to be orchestrated as part of a a Kubernetes Pod, Deployment, DaemonSet, you also specify a particular version of the image, as in:
…
spec:
     containers:
     – name: AcctApp
       image: acctApp:v3
…
In this way, you might have multiple versions of your application running in different deployments.
Applications can also behave differently depending on the configuration information with which they run.
Principle II. Dependencies
Principle 2 of a 12 Factor App is &8220;Explicitly declare and isolate dependencies&8221;.
Making sure that an application&8217;s dependencies are satisfied is something that is practically assumed. For a 12 factor app, that includes not just making sure that the application-specific libraries are available, but also not counting on, say, shelling out to the operating system and assuming system libraries such as curl will be there.  A 12 factor app must be self-contained.
That includes making sure that the application is isolated enough that it&8217;s not affected by conflicting libraries that might be installed on the host machine.
Fortunately, if an application does have any specific or unusual system requirements, both of these requirements are handily satisfied by containers; the container includes all of the dependencies on which the application relies, and also provides a reasonably isolated environment in which the container runs.  (Contrary to popular belief, container environments are not completely isolated, but for most situations, they are Good Enough.)
For applications that are modularized and depend on other components, such as an HTTP service and a log fetcher, Kubernetes provides a way to combine all of these pieces into a single Pod, for an environment that encapsulates those pieces appropriately.
Principle III. Config
Principle 3 of a 12 Factor App is &8220;Store config in the environment&8221;.
The idea behind this principle is that an application should be completely independent from its configuration. In other words, you should be able to move it to another environment without having to touch the source code.
Some developers achieve this goal by creating configuration files of some sort, specifying details such as directories, hostnames, and database credentials. This is an improvement, but it does carry the risk that someone will check a config file into the source control repository.
Instead, 12 factor apps store their configurations as environment variables; these are, as the manifesto says, &8220;unlikely to be checked into the repository by accident&8221;, and they&8217;re operating system independent.
Kubernetes enables you to specify environment variables in manifests via the Downward API, but as these manifests themselves do get checked int source control, that&8217;s not a complete solution.
Instead, you can specify that environment variables should be populated by the contents of Kubernetes ConfigMaps or Secrets, which can be kept separate from the application.  For example, you might define a Pod as:
apiVersion: v1
kind: Pod
metadata:
 name: secret-env-pod
spec:
 containers:
   – name: mycontainer
     image: redis
     env:
       – name: SECRET_USERNAME
         valueFrom:
           secretKeyRef:
             name: mysecret
             key: username
       – name: SECRET_PASSWORD
         valueFrom:
           secretKeyRef:
             name: mysecret
             key: password
       – name: CONFIG_VERSION
         valueFrom:
           configMapKeyRef:
             name: redis-app-config
             key: version.id
As you can see, this Pod receives three environment variables, SECRET_USERNAME, SECRET_PASSWORD, and CONFIG_VERSION, the first two from from referenced Kubernetes Secrets, and the third from a Kubernetes ConfigMap.  This enables you to keep them out of configuration files.
Of course, there&8217;s still a risk of someone mis-handling the files used to create these objects, but it&8217;s them together and institute secure handling policies than it is to weed out dozens of config files scattered around a deployment.
What&8217;s more, there are those in the community that point out that even environment variables are not necessarily safe for their own reasons.  For example, if an app crashes, it may save all of the environment variables to a log or even transmit them to another service.  Diogo Mónica points to a tool called Keywhiz you can use with Kubernetes, creating secure secret storage.
Principle IV. Backing services
Principle 4 of the 12 Factor App is &8220;Treat backing services as attached resources&8221;.
In a 12 Factor app, any services that are not part of the core application, such as databases, external storage, or message queues, should be accessed as a service &8212; via an HTTP or similar request &8212; and specified in the configuration, so that the source of the service can be changed without affecting the core code of the application.
For example, if your application uses a message queuing system, you should be able to change from RabbitMQ to ZeroMQ (or ActiveMQ or even something else) without having to change anything but configuration information.
This requirement has two implications for a Kubernetes-based application.
First, it means that you must think about how your applications take in (and give out) information. For example, if you have a backing database, you wouldn&8217;t want to have a local Mysql instance, even if you&8217;re replicating it to other instances. Instead, you would want to have a separate container that handles database operations, and make those operations callable via an API. This way, if you needed to change to, say, PostgreSQL or a remotely hosted MySQL server, you could create a new container image, update the Pod definition, and restart the Pod (or more likely the Deployment or StatefulSet managing it).  
Similarly, if you&8217;re storing credentials or address information in environment variables backed by a ConfigMap, you can change that information and replace the Pod.
Note that both of these examples assume that though you&8217;re not making any changes to the source code (or even the container image for the main application) you will need to replace the Pod; the ability to do this is actually another principle of a 12 Factor App.
Principle V. Build, release, run
Principle 5 of the 12 Factor App is &8220;Strictly separate build and run stages&8221;.
These days it&8217;s hard to imagine a situation where this is not true, but a twelve-factor app must have a separate build stage.  In other words, you should be able to build or compile the code, then combine that with specific configuration information to create a specific release, then deliberately run the release.
Releases should be identifiable.  You should be able to say, ‘This deployment is running Release 1.14 of this application&8221; or something similar, the same way we say we&8217;re running &8220;the OpenStack Ocata release&8221; or &8220;Kubernetes 1.6&8221;.  They should also be immutable; any changes should lead to a new release.  If this sounds daunting, remember that when we say &8220;application&8221; we&8217;re no longer talking about large, monolithic releases.  Instead, we&8217;re talking about very specific microservices, each of which has its own release, and which can bump releases without causing errors in consuming services.
All of this is so that when the app is running, that &8220;run&8221; process can be completely automated. Twelve factor apps need to be capable of running in an automated fashion because they need to be capable of restarting should there be a problem.
Translating this to the Kubernetes realm, we&8217;ve already said that the application needs to be stored in source control, then built with all of its dependencies.  That&8217;s your build process.  We talked about separating out the configuration information, so that&8217;s what needs to be combined with the build to make a release. And the ability to automatically run the application &8212; or multiple copies of the application &8212; is precisely what Kubernetes constructs like Deployments, ReplicaSets, and DaemonSets do.
Principle VI. Processes
Principle 6 of the 12 Factor App is &8220;Execute the app as one or more stateless processes&8221;.
Stateless processes are a core idea behind cloud native applications. Every twelve-factor application needs to run in individual, share-nothing processes. That means that any time you need to persist information, it needs to be stored in a backing service such as a database.
If you&8217;re new to cloud application programming, this might be deceptively simple; many developers are used to &8220;sticky&8221; sessions, storing information in the session with the confidence that the next request will come to the same server. In a cloud application, however, you must never make that assumption.
Instead, if you&8217;re running a Kubernetes-based application that hosts multiple copies of a particular pod, you must assume that subsequent requests can go anywhere.  To solve this problem, you will want to use some sort of backing volume or database for persistence.
One caveat to this principle is that Kubernetes StatefulSets can enable you to create Pods with stable network identities, so that you can, theoretically, direct requests to a particular pod. Technically speaking, if the process doesn&8217;t actually store state, and the pod can be deleted and recreated and still function properly, it satisfies this requirement &8212; but that&8217;s probably pushing it a bit.
Principle VII. Port binding
Principle 7 of the 12 Factor App is &8220;Export services via port binding&8221;.
In an environment where we&8217;re assuming that different functionalities are handled by different processes, it&8217;s easy to make the connection that these functionalities should be available via a protocol such as HTTP, so it&8217;s common for applications to be run behind web servers such as Apache or Tomcat.  Twelve-factor apps, however, should not be depend on an additional application in that way; remember, every function should be in its own process, isolated from everything else. Instead, the 12 Factor App manifesto recommends adding a web server library or something similar to the app itself, so that the app can await requests on a defined port, whether it&8217;s using HTTP or another protocol.
In a Kubernetes-based application, this is done partly through the architecture of the application itself, and partly by making sure that the application has all of its dependencies as part of the creation of the base containers on which the application is built.
Principle VIII. Concurrency
Principle 8 of the 12 Factor App is to &8220;Scale out via the process model&8221;.
When you&8217;re writing a twelve-factor app, make sure that you&8217;re designing it to be scaled out, rather than scaled up. That means that in order to add more capacity, you should be able to add more instances rather than more memory or CPU to the machine on which the app is running. Note that this specifically means being able to start additional processes on additional machines, which is, fortunately, a key capability of Kubernetes.
Principle IX. Disposability
Principle 9 of the 12 Factor App is to &8220;Maximize robustness with fast startup and graceful shutdown&8221;.
It seems like this principle was tailor made for containers and Kubernetes-based applications. The idea that processes should be disposable means that at any time, an application can die and the user won&8217;t be affected, either because there are others to take its place, because it&8217;ll start right up again, or both.
Containers are built on this principle, of course, and Kubernetes structures that manage multiple instances and maintain a certain level of availability even in the face of problems, such as ReplicaSets, complete the picture.
Principle X. Dev/prod parity
Principle 10 of the 12 Factor App is &8220;Keep development, staging, and production as similar as possible&8221;.
This is another principle that seems like it should be obvious, but is deeper than most people think. On the surface level, it does mean that you should have identical development, staging, and production environments, inasmuch as that is possible. One way to accomplish this is through the use of Kubernetes namespaces, enabling you to (theoretically) run code on the same actual cluster against the same actual systems while still keeping environments separate. In some situations, you can also use tools such as Minikube or kubeadm-dind-cluster to create near-clones of production systems.
At a deeper level, though, as the Twelve-Factor App manifesto puts it, it&8217;s about three different types of &8220;gaps&8221;:

The time gap: A developer may work on code that takes days, weeks, or even months to go into production.

The personnel gap: Developers write code, ops engineers deploy it.

The tools gap: Developers may be using a stack like Nginx, SQLite, and OS X, while the production deploy uses Apache, MySQL, and Linux.

The goal here is to create a Continuous Integration/Continuous Deployment situation in which changes can go into production virtually immediately (after testing, of course!), deployed by the developers who wrote it so they can actually see it in production, using the same tools on which the code was actually written in order to minimize the possibility of compatibility errors between environments.
Some of these factors are outside of the realm of Kubernetes, of course; the personnel gap is a cultural issue, for example. The time and tools gaps, however, can be helped in two ways.
For the time gap, Kubernetes-based applications are, of course, based on containers, which themselves are based on images that are stored in version-control systems, so they lend themselves to CI/CD. They can also be updated via rolling updates that can be rolled back in case of problems, so they&8217;re well-suited to this kind of environment.
As far as the tools gap is concerned, the architecture of Kubernetes-based applications make it easier to manage, both by making local dependencies simple to include in the various images, and by modularizing the application in such a way that external backing services can be standardized.
Principle XI. Logs
Principle 11 of the 12 Factor App is to &8220;Treat logs as event streams&8221;.
While most traditional applications store log information in a file, the Twelve-Factor app directs it, instead, to stdout as a stream of events; it&8217;s the execution environment that&8217;s responsible for collecting those events. That might be as simple as redirecting stdout to a file, but in most cases it involves using a log router such as Fluentd and saving the logs to Hadoop or a service such as Splunk.
In Kubernetes, you have at least two choices for automatic logging capture: Stackdriver Logging if you&8217;re using Google Cloud, and Elasticsearch if you&8217;re not.  You can find more information on setting Kubernetes logging destinations here.
Principle XII. Admin processes
Principle 12 of the 12 Factor App is &8220;Run admin/management tasks as one-off processes&8221;.
This principle involves separating admin tasks such as migrating a database or inspecting records from the rest of the application. Even though they&8217;re separate, however, they must still be run in the same environment and against the same base code and configuration as the application, and their code must be shipped alongside the application to prevent drift.
You can implement this a number of different ways in Kubernetes-based applications, depending on the size and scale of the application itself. For example, for small tasks, you might use kubectl exec to operate on a specific container, or you can use the Kubernetes Job to run a self-contained application. For more complicated tasks that involve orchestration of changes, however, you can also use Kubernetes Helm charts.
How many of these factors did you hit?
Unless you&8217;re still building desktop applications, chances are you can feel good about hitting at least a few of these essential principles of twelve-factor apps. But chances are you also found at least one or two you can probably work a little harder on.
So we want to know: which of these factors are the biggest struggle for you? Where do you think you need to work harder, and what would make it easier for you?  Let us know in the comments.
