kubernetes multiple environments

Published

on

Multiple clusters will usually mean that many of them have their own configurations like the Kubernetes version and other third-party monitoring tools. In this guide, we will see how you can deploy an example application to different environments using different Helm values and how to automate the whole process with Codefresh pipelines. Subscribe to our monthly newsletter to see the latest Codefresh news and updates! Editor’s note: today’s guest post is by Chesley Brown, Full-Stack Engineer, at InVision, talking about how they build and open sourced kit to help them to continuously deploy updates to multiple clusters. They allow segregating the resources within a cluster, so you can deploy multiple applications or environments within it. Helm is the package manager of Kubernetes. Security must be a first-class citizen of any organization’s DevOps process (often referred to as DevSecOps). Create Your Free Account today! This is in contrast to purchasing additional worker nodes, which increases running costs. Kubernetes includes a cool feature called [namespaces], which enable you to manage different environments within the same cluster. 4 min read. This cost translates to roughly $144 per month — which can have a significant impact on overall costs if you require a large number of clusters. These limits are quite extensive, and generally are sufficient for most production applications. You should get an empty report since we haven’t deployed our application yet. However, there is a delicate balance between cost-effectiveness and efficiency. from multiple environments spanning on-premises, private and public clouds. While normally a Helm chart contains only a single values file (for the default configuration), it makes sense to create different value files for all different environments. In this article we will look at how to use Kubernetes Kustomize for multiple environments. Qu'est-ce qui est considéré comme une bonne pratique de gestion des environnements multiples (QA, Staging, Production, Dev, etc.)? Terraform is a tool by HashiCorpoffered in both open source and enterprise versions. In addition to Red Hat OpenShift, StackRox will continue to support multiple Kubernetes platforms, including Amazon Elastic Kubernetes Service (EKS), Microsoft Azure Kubernetes Service (AKS), and Google Kubernetes Engine (GKE). Using predefined environments is the traditional way of deploying applications and works well for several scenarios. Download the latest version of Helm on your local workstation and verify that it is working correctly by typing. "The Hitachi Kubernetes Service provides an intuitive, multicloud dashboard with powerful APIs to manage our K8s cluster lifecycles, regardless of … For example, you can have different test and staging environments in the same cluster of machines, potentially saving resources. As an example, the number of replicas of the application is parameterized. You should also remove the namespaces if you want to clean-up your cluster completely. They can be deployed across multiple datacenters on-premise, in the public cloud, and at the edge. Shift left, or suffer the consequences. Kubernetes makes this easy enough by making it possible to quickly roll out multiple nodes with the same configuration. Some popular workflows are: There are more possibilities and all of them are possible with Codefresh. There are other benefits to using one Kubernetes Cluster. The short answer is yes – but for more on this topic, read on: It’s quite common for organizations to use a cluster to run an application or a particular environment such as staging or production. Is there a way to avoid the increased costs from implementing an increasing number of clusters? There are a few ways to achieve that using Kubernetes: one way is to create a full blown cluster for each division, but the way we’re focusing on is using Kubernetes namespaces feature . One of the advantages both Mirantis Container Cloud and the Lens IDE share is that both enable you to easily work with multiple Kubernetes clusters. So how does this compute to cost savings? The Master node manages the state of the cluster, while the worker nodes run the application. Before automating the deployment, let’s get familiar with how the application looks in different environments by installing it manually with the Helm executable. https://github.com/codefresh-contrib/helm-promotion-sample-app/tree/master/chart, searches for the file /config/settings.ini, Deploying to Artifactory/Bintray from Codefresh pipelines, Netdata: The Easiest Way to Monitor Your Kubernetes Cluster, Obtain access to a Kubernetes cluster (either on the cloud or a local one like, Setup your terminal with a kubeconfig (instructions differ depending on your cluster type), Helm is gathering all the Kubernetes manifests (deployment + configmap+ service) along with the respective values file, The properties that contain templates are replaced with their literal values. Nightly builds), Using multiple pipelines where one pipeline is deploying to production for the master branch and other pipelines are deploying to QA/stating only when a Pull request is created, A Helm deploy step that deploys to “staging” if the branch is not “master”. (I always delete un-used applications, no need to spend money on hosting them) You will need to incur fixed costs for teams that manage your clusters. While having a single cluster can lead to cost savings in many ways, it can become inefficient when resource limits reach the upper limits allowed per cluster. To setup your own cluster, google minikube, or tectonic, or try this:https://github.com/rvmey/KubernetesCentosInstall Notice also that this configmap is named as application-settings (we will use this name later in the deployment). And with the power of Codefresh, you also have access to a visual dashboard for inspecting all your environments on a single screen. The format of the file depends on your programming language and framework. You can find the IP addresses with: Look under the “external-ip” column. They allow segregating the resources within a cluster, so you can deploy multiple applications or environments within it. However, adopting Kubernetes is not a walk in the park. Namespaces are one of the most significant benefits of Kubernetes clusters. The last piece of the puzzle is to tell Kubernetes to “mount” the contents of this configmap as a file at /config. As you can see, because the configmap is part of the Helm chart, we have the capability to template the values of the configmap like any other Kubernetes manifest. Some popular solutions are Java properties, .env files, Windows INI, and even JSON or YAML. These environments need some level of isolation. You can manually create entries in this dashboard by adding a new environment and pointing Codefresh to your cluster and the namespace of your release (we will automate this part as well with pipelines in the next section). DevOps engineers and Kubernetes admins often need to deploy their applications and services to multiple environments. Trying to run the whole stack locally is impossible. A config map is a configuration object that holds specific variables that can be passed in the application container in multiple forms such as a file or as environment variables. Let’s look at both the direct and indirect forms of cost savings: Each of your clusters will require a master node, which adds to the total number of nodes your application requires. Helm is using the same credentials as kubectl for cluster access, so before starting with Helm: Feel free also to work with the cloud shell of your cloud provider if available, as it configures everything for you in advance (and in some cases, even Helm is preinstalled). username and password for a database) as well as properties for Kubernetes manifests (e.g. You can see the definition of replicaCount inside the values YAML for each environment. Using Helm to Deploy a Kubernetes Application to Multiple Environments (QA/Stage/Prod) One of the most typical challenges when deploying a complex application is the handling of different deployment environments during the software lifecycle. All of these add to the overhead costs of managing multiple Kubernetes clusters, making a single cluster the best option for cost savings. In this article, we will discuss how innovative messaging platforms enable microservices from multiple environments to communicate with each other, in a way that provides speed, flexibility, security and scale. What if you want to test a change before applying it into the production/live environment? A Kubernetes cluster usually contains at least one master node and one or more worker nodes. You can find an example application that follows this practice at: https://github.com/codefresh-contrib/helm-promotion-sample-app/tree/master/chart. You can use Azure Arc to register Kubernetes clusters hosted outside of Microsoft Azure, and use Azure tools to manage these clusters alongside clusters hosted in Azure Kubernetes Service (AKS). Thousands of businesses have migrated to the cloud within a short period in order to leverage the power of Kubernetes. Many of them are technical in nature, but you will also need to deal with the reluctance many people display when being introduced to new technologies. Ces environnements ont besoin d’un certain niveau d’isolation. For this particular case, the Environment dashboard is the most helpful one, as it shows you the classical “box” view that you would expect. avec Kubernetes. A more advanced practice would be to have dynamic environments (apart from production) that are created on-demand when a Pull Request is opened and torn down when a pull request is closed. //github.com/codefresh-contrib/helm-promotion-sample-app.git, # possible values: production, development, staging, QA, # possible values : production, development, staging, qa, "codefresh-contrib/helm-promotion-sample-app", Learn how to declare cloud resources using, The last year was undeniably a different year for everybody. But can we improve the process any further? Here is an example of the file: These settings are all dummy variables. SYDNEY – 20 Jan 2021 – Hitachi Vantara, the digital infrastructure and solutions subsidiary of Hitachi, Ltd. (TSE: 6501), today announced the availability of Hitachi Kubernetes Service, an enterprise-grade solution for the complex challenge of managing multiple Kubernetes environments. Here is the graphical view: The last two steps use pipeline conditionals, so only one of them will be executed according to the branch name. The example application uses the INI file format and searches for the file /config/settings.ini. While it seems quite logical to have each environment and/or application in its own cluster, it is not required, and it’s not the only way. You will have multiple environments where you deploy services, including environments for development, smoke testing, integration testing, load testing, and finally production. In the following two-part post, we will explore the creation of a GKE cluster, replete with the latest version of Istio, often referred to as IoK (Istio on Kubernetes). If approval is granted the commit is also deployed to production, Using multiple pipelines where one pipeline is responsible for production deployments only and another pipeline is deploying staging releases on a regular schedule (a.k.a. At this point, each team definitely needs its own namespace. At the foundational level, Kubernetes is an open source project, originally started by Google and now developed as a multi-stakeholder effort under the auspices of the Linux Foundation's Cloud Native Computing Foundation (CNCF). But how do we pass values to the application itself? Building a Kubernetes-based Solution in a Hybrid Cloud Environment. So we needed a solution to help our customers manage and govern multiple clusters, deployed across multiple clouds by multiple teams. par exemple, une équipe travaille sur un produit qui nécessite le déploiement de quelques API, ainsi qu'une application frontale. Helm includes a templating mechanism that allows you to replace common properties in Kubernetes manifests. The additional cost of maintaining multiple clusters becomes immaterial in such cases. However, if you are with AWS Kubernetes Engine (AKE) there will be an additional charge of $.10 per master node, which is approximately double the cost of a worker node (based on EC2 pricing). About Kubernetes Kubernetes is an open-source tool that manages deployment, scaling, and orchestration of containerized applications. The choice is yours. While your Kubernetes provider would take care of most of the maintenance of your nodes and clusters, there will be some activities that require human intervention – for example, testing resource allocations of namespaces and ensuring that they are optimized. He lives and breathes automation, good testing practices and stress-free deployments. That means, with careful planning, you can deploy all your environments and applications within a single cluster. Kubernetes is an innovative and exciting platform for teams to deploy their applications and experience the power of the cloud, containers, and microservices. Our research has also consistently showed a lack of DevOps and cloud-native skills and talent amid increasingly high demand. Let’s do that now. Last update: January 17, 2019 When building your application stack to work on Kubernetes, the basic pod configuration is usually done by setting different environment variables.Sometimes you want to configure just a few of them for a particular pod or to define a set of environment variables that can be shared by multiple … Environnements multiples (Staging, QA, production, etc.) Here is the part of the deployment YAML that does this: Now that we have seen all the pieces of the puzzle you should understand what happens behind the scenes when you deploy the application. As at version 1.18, Kubernetes allows a cluster to have up to 5,000 nodes, 150,000 total pods, 300,000 total containers, and 100 pods per node. Multiple Environments in One Cluster When using Kubernetes for a team, you usually want to have an isolated environment for each developer, branch , or pull request. Here we pass the replicaCount parameter to the deployment YAML. Kubernetes has revolutionized application deployment during the last few years. Managing Applications Across Multiple Kubernetes Environments with Istio: Part 1. As your applications scale with the growth of your business, you will observe that the costs involved are also growing at an alarming rate. When I started this Kubernetes infrastructure project I had never used Terraform before, though I was familiar with it. Resources such as computing, storage, and networking are virtually unlimited and can cater even to the most demanding apps. We started with Docker in our development environments, trying to get consistency there first. There are many complexities related to setting up Kubernetes in a manner that works for your organization. Upon overcoming these challenges, you will be able to arrive at a point where your applications are running smoothly on shared Kubernetes clusters. It groups containers that make up an application into logical units for easy management and discovery. We will then deploy, perform integration testing, and promote an application across multiple environments within the cluster. The most typical setup is the trilogy of QA/Staging/Production environments. We will see this scenario in our next tutorial. Resources from namespaces that are receiving lesser traffic can be allocated to the more important ones when needed. You will be able to use namespaces to control the amount of resources allocated to each application and/or environment. Kubernetes makes this easy enough by making it possible to quickly roll out multiple nodes with the same configuration. Supporting Quotes "While our customers love container technology, they are challenged by the complexity to deploy and securely manage containers at scale across multiple cloud environments… For alternative workflows regarding environment deployments see the documentation page. The argument that many experts use to discourage the use of a single cluster is the possibility of failure and downtime. Michael Handa April 28, 2020 Cloud Technology, Containerization, Kubernetes, Microservices. Open the respective URL in your browser and you will see how the application looks on each environment: To uninstall your app you can also use Helm like below: Note that if you are using a cloud Kubernetes cluster, the load balancers used in the apps cost extra, and it is best to delete your apps at the end of this tutorial. This feature allows you to deploy nodes across zones in order to ensure continuity and high availability. With modern cloud-native applications, Kubernetes environments are becoming highly distributed. Another argument is that a single cluster cannot handle large numbers of nodes and pods. In this post we want to do some updates to our deployed application, roll them back in the case of errors and last but not least use multiple environments so we can test our application before deploying to production. An application developer needs an easy way to deploy to the different environments and also to understand what version is deployed where. Namespaces are one of the most significant benefits of Kubernetes clusters. At. You can read more about them on the official Kubernetes blog. First let’s create 3 namespaces, one for each “environment”: And then deploy the Helm chart on each environment by passing a different values file for each installation: You should now wait a bit so that all deployments come up. For more information on using the environment dashboard see the documentation page. There are many ways to pass values to an application, but one of the easiest ones is using plain files (for a small number of values you could also use environment variables. In the past, I have used numerous other tools such as Puppet, Ansible, The Foreman, and CloudFormation as well as other “roll your own” tooling around various SDKs and libraries. With this project though I wanted to learn something new; enter Terr… You can see all your deployments with: Each application also exposes a public endpoint. Kostis is a software engineer/technical-writer dual class character. Helm packages (called charts) are a set of Kubernetes manifests (that include templates) plus a set of values for these templates. This type of saving can be even more critical during seasonal periods that see peak activity on some applications. New to Codefresh? This also includes the configmap, The resulting manifests are sent to Kubernetes by Helm, Kubernetes is looking at the deployments and sees that it requires an extra configmap to be passed as a file, The contents of the configmap are mounted at /config/settings.ini inside the application container, The application starts and reads the configuration file (unaware of how the file was written there), Using a single pipeline that deploys the master branch to production and all other non-master branches to staging and/or QA, Using a single pipeline that deploys all commits to staging and then waiting for manual approval. Create your FREE Codefresh account and start making pipelines fast. However, Kubernetes introduced support for running a single cluster in multiple zones as far back as version 1.12. number of replicas). In our case, we will use a configmap-passed-as-file as this is what our application expects. One of the most typical challenges when deploying a complex application is the handling of different deployment environments during the software lifecycle. Here we have 3 values files for each environment: If you look at the values you will see that we have defined both application level properties (e.g. Juniper Networks expanded its Contrail Networking to include better support for Kubernetes environments running on Amazon Web Services (AWS), Google … Our Docker journey at InVision may sound familiar. One of the biggest challenges when adopting Kubernetes is managing multiple developer platforms, who need to operate across many environments and often many clouds. There are many ways to deploy in multiple environments and your own process will depend on your team and your organizational needs. As you have seen, using helm for different environments is straightforward and trivial to automate with Codefresh pipelines. Consider the following: A cloud gaming company develops and operates an interactive online service for customers in Asia. For our example we will focus on the first case, a single pipeline that depending on the branch name will deploy the application to the respective environment. Depending on the setup, an environment could mean a Kubernetes cluster or a… Harmonize environments and deploy Kubernetes anywhere with GitOps Scale Kubernetes on multiple clusters and across clouds. First I will re-deploy my original application. Specifically for Kubernetes deployments, the Helm package manager is a great solution for handling environment configuration. However, Kubernetes has no native concept of environments. Similarly, you will also be able to run server and batch jobs without affecting other namespaces. Google Kubernetes Engine (GKE) provides one free cluster per zone, per account, making it more cost-effective to have a single cluster. For example, if you have a spring boot application and multiple environments such as dev, testing and production; you might want the same YAML file configured such that it deploys to separate … The most typical setup is the trilogy of QA/Staging/Production environments. Within large enterprise companies, Kubernetes adoption typically happens in pockets across application teams, who may be running Kubernetes in different environments. This aspect of cost savings becomes prominent if you host multiple environments such as d ev, staging, and production on the same cluster. They also define which environments are affected in the environment dashboard. Earlier this month, we announced the availability of Armed with separate clusters for each of your environments and/or applications, adoption will increase over time. But in an environment where enterprises operate both on-premises and in the cloud (and perhaps multiple clouds), operating Kubernetes clusters across multiple environments brings about a new set of deployment challenges. They are not actually used in the application, they are only shown in the http response as plain text. Kubernetes deployment in multi-cloud environments would be easier with an industry-standard declarative API, IT pros say, and some hope the upstream Cluster API project will eventually fill that need. There are many ways to do that in Kubernetes (init containers, volumes) but the simplest one is via the use of configmaps. The ease of managing a single cluster is one of the most compelling reasons to opt for deploying all your applications within the same cluster. For the values that deal with the Kubernetes cluster, the process is straightforward. Please visit our Blue Sentry Blog if you enjoyed this article and want to learn more about topics like Kubernetes, Cloud Computing, and DevOps. That means, with careful planning, you can deploy all your environments and applications … In a production setting , you might have multiple environments and each deployment would need separate configuration. One cloud provider is selected with multiple regions across Asia and the provider’s managed Kubernetes service is being leveraged. If you start committing and pushing to the different branches you will see the appropriate deploy step executing (you can also run the pipeline manually and simply choose a branch by yourself). If everything goes ok you should see a list of nodes that comprise your cluster. Because some environments don’t always require the same amount of resources, they can be shifted to other namespaces, which are experiencing a spike in user activity. A Kubernetes cluster is a group of nodes used to deploy containerized applications. Whether it is shutting down idle nodes or scaling other resources, having a single cluster makes this process much easier. Kubernetes cluster management is how an IT team manages a group of Kubernetes clusters. This reference architecture demonstrates how Azure Arc extends Kubernetes cluster management and configuration across customer data centers, edge locations, and multiple cloud environments. Creating multi-environment Kubernetes deployments The declarative nature of Kubernetes resources provides a convenient way to describe the desired state of your cluster. For example, the production environment defines 2 replicas, while the QA and staging environments have only one. Naturally, as you increase the number of clusters, there is an increase in the costs associated in terms of having additional computing resources for master nodes. The need for dedicated personnel positively correlates with the number of clusters. What’s more, the Mirantis Container Cloud Lens extension ties the two together, making it simple to connect some or all of the clouds in your Mirantis Container Cloud to your Lens install. Let’s consider the savings from the three main Managed Kubernetes services. Read my previous blog to understand how to set up Kubernetes cluster, so I assuming that the reader has a running Kubernetes cluster and plans to … Multiple Environments in One Cluster When using Kubernetes for a team, you usually want to have an isolated environment for each developer, branch , or pull request. These multiple dimensions of security in Kubernetes cannot be covered in a single article, but the following checklist covers the major areas of security that should be reviewed across the stack. It is written in Go and has a proprietary DSL for user interaction. Azure Kubernetes Service (AKS) does not charge additionally for cluster management. Blue Sentry Ensures Security and Compliance, Why a “Sandbox Database” is Important to Software Developers, Mindful Migration: Six Steps to Ensure Success, Pipeline Automation: The Keys to Unlocking the Right Outcome For Your CI/CD Process, Blue Sentry Launches Free Pre-Migration Cost Assessment Service. For more information on templates see the Helm documentation page. Now that you have seen how the application looks in each environment, we can dive into the details on how the Helm values are actually used. This explains the templating capabilities of Helm for Kubernetes manifests. Using a Kubernetes-aware Continuous Delivery system (e.g., Spinnaker) is highly recommended. Managing resources of a single cluster is simple for obvious reasons. Using manually the helm executable to deploy our application is great for experimentation, but in a real application, you should create a pipeline that automatically deploys it to the respective environment. So, if you use Kubernetes for your application, you have at least one cluster. In addition to the direct cost of increased master nodes, you may have additional costs depending on your service provider. This means that once the application is deployed to the cluster, we need to provide a file in this format in the /config/settings.ini path inside the container. Codefresh contains several graphical dashboards that allow you to get an overview of all your Helm releases and their current deployment status. Given the elastic nature of Kubernetes however, static environments are not always cost-effective. However, the project remains in its alpha stage and requires more polish.
