Introduction:
Alibaba Cloud Container Service for Kubernetes (ACK) can be used for creating Microservice applications that support high availability and scalability with low cost. It also provides the features such as deployment, scheduling, orchestration and automated CI/CD for building the containerized applications quickly.
Different Types of ACK Clusters are
(i)Dedicated Kubernetes: You need to manually create master and worker nodes. You are only charged for master nodes, worker nodes, and other infrastructure resources
(ii)Managed Kubernetes: You only need to create and manage worker nodes while master nodes will be managed by ACK.
(iii)Serverless Kubernetes: You can directly launch applications without creating or managing any node.
In this blog, we are going to learn how to deploy an application in the ACK cluster of Alibaba Cloud.
Various steps in deploying Application in ACK Cluster using Alibaba Cloud Container Services are
1.Setting up repository
2.Creating ACK Cluster
3.Creating Container Registry
4.Create deployment and service
1.Setting up repository
Login to your Github repository by providing your username and password. Create a docker file with all the maven build and all the needed commands to run the application in the port 8080.create all the necessary files for the application in the repository.
2.Creating ACK Cluster
In Alibaba Cloud Console,Choose “Container Service for Kubernetes” and then select Standard Dedicate cluster and follow the following steps
2.1:Cluster Configuration
2.2:Master Node Configuration
2.3:Worker Node Configuration
2.4:Component Configuration
2.1:Cluster Configuration:
After choosing the needed cluster for deploying your application(here I have chosen Standard Dedicate cluster),You have to provided basic details such as Cluster Name,Region,Version and Container runtime.
After providing basic information you have to provide details such as VPC,Vswitch,Network Plugin,Pod CIDR Block,Service CIDR Block and finally select public access if you want to access the service through the internet.
2.2:Master Node Configuration
In master node configuration you have to select one of the Available billing methods such as pay-as-you-go, subscription model and you have to select the no of master nodes required for the cluster.
Finally you have to select the required instance type for your application from the available instances.
2.3:Worker Node Configuration
In the worker node configuration you have to select the required instance by clicking select instance,quantity of worker node required and its disk size,operating system and login type.
2.4:Component Configuration
In component configuration you can choose additional features such as Ingress Controller,Cloud monitor,Log service and creating ingress Dashboard.Finally after selecting the required component you can confirm the order and inturn you can create the cluster by using create cluster.
3.Creating Container Registry
In the Alibaba cloud console, select the container registry and follow the step for creating the registry.
3.1.Creating repository and code source
3.2.Adding Build Rule
3.3.Building the registry
3.1.Creating repository and code source
For creating container repository you have to provide repository info and code source
In repository info you have to provide Region, namespace, Repository name, Repository type, summary and description.
After providing repository info, bind with the GitHub repository by providing GitHub username and password.
3.2.Adding Build Rule
Create the build rule by providing type, code branch, docker file and tags.
3.3.Building the registry
-Finally, build the registry by clicking the build button and after a few minutes once the build is completed it displays successful in the build status.
4.Create deployment and service
Go to Container service for kubernetes dashboard and select the Cluster created and continue the following steps
4.1:Create a deployment by providing details such as name, cluster, namespace, replicas and type.
4.2:In the container provider select image name and image version.
4.3:Create a service by providing details such as name, namespace and service load balancer.
4.4:In the local port, mapping provides the name of service, service port as 80, container port as 8080 and click ok.
4.5:Finally, the service will be created and you can view the service by clicking the public IP address present in the service.
Wrapping it Up:
Container Service for Kubernetes makes easy the creation,deployment and service creation in clusters.It can manage the entire life cycle of the container from creation to deletion.In this blog we leant how to create and deploy containerized application using Alibaba Container Service,Container registry and GitHub.
