Manage Kubernetes Clusters on AWS Using Kops. Any containerized application typically consists of multiple containers. There are containers for the application itself, a database, possibly a web server, and so on. During development, its normal to build and test this multi container application on a single host. This approach works fine during early dev and test cycles but becomes a single point of failure for production, when application availability is critical. In such cases, a multi container application can be deployed on multiple hosts. Customers may need an external tool to manage such multi container, multi host deployments. Container orchestration frameworks provides the capability of cluster management, scheduling containers on different hosts, service discovery and load balancing, crash recovery, and other related functionalities. Products/On-line_DocumentationV3/LoriotProV3Doc/K11-Using_an_external_Database/K11-A1_img/image004.jpg' alt='Hana Odbc Driver' title='Hana Odbc Driver' />There are multiple options for container orchestration on Amazon Web Services Amazon ECS, Docker for AWS, and DCOS. Another popular option for container orchestration on AWS is Kubernetes. There are multiple ways to run a Kubernetes cluster on AWS. This multi part blog series provides a brief overview and explains some of these approaches in detail. This first post explains how to create a Kubernetes cluster on AWS using kops.

Applications packaged as Docker images can be easily deployed, scaled, and managed in a Kubernetes cluster. Some of the key features of Kubernetes are Self healing. Failed containers are restarted to ensure that the desired state of the application is maintained. If a node in the cluster dies, then the containers are rescheduled on a different node. Containers that do not respond to application defined health check are terminated, and thus rescheduled. Horizontal scaling. Number of containers can be easily scaled up and down automatically based upon CPU utilization, or manually using a command. Service discovery and load balancing. Multiple containers can be grouped together discoverable using a DNS name. The service can be load balanced with integration to the native LB provided by the cloud provider. Application upgrades and rollbacks. Applications can be upgraded to a newer version without an impact to the existing one. If something goes wrong, Kubernetes rolls back the change. Kops, short for Kubernetes Operations, is a set of tools for installing, operating, and deleting Kubernetes clusters in the cloud. A rolling upgrade of an older version of Kubernetes to a new version can also be performed. It also manages the cluster add ons. After the cluster is created, the usual kubectl CLI can be used to manage resources in the cluster. Download Kops and Kubectl. There is no need to download the Kubernetes binary distribution for creating a cluster using kops. However, you do need to download the kops CLI. It then takes care of downloading the right Kubernetes binary in the cloud, and provisions the cluster. The different download options for kops are explained at github. On Mac. OS, the easiest way to install kops is using the brew package manager. The version of kops can be verified using the kops version command, which shows Version 1. In addition, download kubectl. This is required to manage the Kubernetes cluster. Microsoft Flight Simulator X 2012 Torrent. The latest version of kubectl can be downloaded using the following command curl LO https storage. Make sure to include the directory where kubectl is downloaded in your PATH. IAM user permission. The IAM user to create the Kubernetes cluster must have the following permissions Amazon. EC2. Full. Access. Amazon. Route. 53. Full. Access. Amazon. S3. Full. Access. IAMFull. Access. Amazon. VPCFull. Access. Alternatively, a new IAM user may be created and the policies attached as explained at github. Create an Amazon S3 bucket for the Kubernetes state store. Kops needs a state store to store configuration information of the cluster. For example, how many nodes, instance type of each node, and Kubernetes version. The state is stored during the initial cluster creation. Any subsequent changes to the cluster are also persisted to this store as well. News information about SAP Business Intelligence tools and SAP HANA. As of publication, Amazon S3 is the only supported storage mechanism. Create a S3 bucket and pass that to the kops CLI during cluster creation. This post uses the bucket name kubernetes aws io. Bucket names must be unique you have to use a different name. SiteCollectionImages/How-to-connect-native-SharePoint-lists-to-SAP-7.png' alt='Sap Hana Odbc Driver' title='Sap Hana Odbc Driver' />Create an S3 bucket aws s. I strongly recommend versioning this bucket in case you ever need to revert or recover a previous version of the cluster. This can be enabled using the AWS CLI as well aws s. StatusEnabled. For convenience, you can also define KOPSSTATESTORE environment variable pointing to the S3 bucket. For example export KOPSSTATESTOREs. This environment variable is then used by the kops CLI. DNS configuration. Hana Odbc Driver' title='Hana Odbc Driver' />As of Kops 1. This domain allows the worker nodes to discover the master and the master to discover all the etcd servers. This is also needed for kubectl to be able to talk directly with the master. This domain may be registered with AWS, in which case a Route 5. Alternatively, this domain may be at a different regist In this case, create a Route 5. Specify the name server NS records from the created zone as NS records with the domain regist This post uses a kubernetes aws. Generate a Route 5. AWS CLI. Download jq to run this command IDuuidgen. ID. jq. Delegation. Set. Name. Servers. This shows an output such as the following. Create NS records for the domain with your regist Different options on how to configure DNS for the cluster are explained at github. Experimental support to create a gossip based cluster was added in Kops 1. This post uses a DNS based approach, as that is more mature and well tested. Create the Kubernetes cluster. The Kops CLI can be used to create a highly available cluster, with multiple master nodes spread across multiple Availability Zones. Workers can be spread across multiple zones as well. Some of the tasks that happen behind the scene during cluster creation are Provisioning EC2 instances. Setting up AWS resources such as networks, Auto Scaling groups, IAM users, and security groups. Installing Kubernetes. Start the Kubernetes cluster using the following command kops create cluster. In this command zones. Defines the zones in which the cluster is going to be created. Multiple comma separated zones can be specified to span the cluster across multiple zones. Defines the clusters name. Points to the S3 bucket that is the state store. Immediately creates the cluster. Otherwise, only the cloud resources are created and the cluster needs to be started explicitly using the command kops update yes. If the cluster needs to be edited, then the kops edit cluster command can be used. This starts a single master and two worker node Kubernetes cluster. The master is in an Auto Scaling group and the worker nodes are in a separate group. By default, the master node is m. Master and worker nodes are assigned separate IAM roles as well. Wait for a few minutes for the cluster to be created. The cluster can be verified using the command kops validate cluster states. It shows the following output Using cluster from kubectl context cluster. Validating cluster cluster. INSTANCE GROUPS. NAME             ROLE     MACHINETYPE    MIN    MAX    SUBNETS.
