Deployments

Deployments is stateless application. For details of Deployment, please see [kubernets official documentation-Deployments](https://kubernetes.io/docs/concepts/workloads/controllers/ deployment/).

Pod is the smallest orchestration unit of Kubernetes, stateless deployment applications that is, by declaring pod templates and other information orchestration deployment of stateless applications, for pods exactly the same, no order, indifferent to the application running in which host.

Entry: In the cloud management platform click the top left corner navigation menu, and click “Containers/Applications/Deployments” menu item in the left menu bar that pops up to enter the Deployments page.

View Deployments Applications

This function is used to filter stateless application information based on clusters and namespaces.

1. On the stateless page, by default, you can view stateless application information for all namespaces under a cluster.

2. When there are multiple clusters in the environment, click the input box on the right side of the cluster at the top of the list and select other clusters to view the stateless application information of all namespaces under other clusters.

3. When there are multiple namespaces under the cluster, click the input box on the right side of the namespace above the list, select the namespace, and view the stateless application information under the specified namespace.

   

Create Deployments

This function is used to create a stateless application deployment by mirroring.

1. On the Deployments page, click the “New” button at the top of the list to enter theCreate Deployments Application page.

2. Set the following parameters.

   • Name: The name of the deployment.
   • Cluster: Select the cluster to which the stateless application belongs.
   • Namespace: Select the namespace to which the stateless application belongs. The namespace is used to logically divide the cluster. deployment, pod, service, etc. all belong to a namespace. Kubernetes cluster will generate default, kube-system, kube-public and other namespaces by default after the cluster is created.
   • Number of container groups: Set the number of container group Pods, which corresponds to the spec.replicas value in the yaml file.
   • Image key: you need to set the key when accessing private repository, support new and select existing key.
   • Service: Set the access method of stateless application and container group, including internal access and external access of the cluster.
     • Internal: A ClusterIP will be automatically generated for access inside the cluster and between container groups.
       • Target port: The target port is the port on the pod.
       • Service port: The user access port.
       • Protocol: Select the protocol used by the application, including TCP and UDP.
     • External: will be used with the load balancing function for access outside the cluster. Before using external service, you need to create load balancing cluster and nodes in load balancing first. When creating external service, a load balancing instance will be created in load balancing synchronously.
       • Load balancing network: select IP subnet, the system will automatically assign an IP address from the IP subnet as the access IP.
       • Target port: The target port is the port on the pod.
       • Service port: The external user access port.
       • Protocol: Select the protocol used by the application, including TCP and UDP.
   • Restart Policy: Only supports always, which means the container always restarts the container when it exits.
   • Advanced Configuration: Configure tags and notes according to requirements.
     • Tag: Customize to set the tag of the stateless application.
     • Remarks: Customize setting remarks information for stateless applications.
   • Containers: You can create one or more containers for the stateless application according to the requirements, you can click to add several different containers.

     • Name: Customize the container name.

     • Container image: If you only enter the image name, the default is to use the image on dockerhub, if you need to use the private repository image, you need to set the repository/image. This example directly enter nginx.

     • CPU/Memory: set the CPU and memory size occupied by the container.

     • Container commands, command parameters: set the container commands and parameters. The container naming corresponds to spec.containers.command, and the parameters correspond to spec.containers.args. e.g. command: [“perl”, “-Mbignum=bpi”, “-wle”, “print bpi(2000)"] in the yaml file, you need to enter the following information in form container command to enter the following information.

       $ perl -Mbignum=bpi -wle print bpi(2000)
       

     • Data volume: Set the storage declaration and mount point for the container in Pod by key-value pair, you need to create the storage volume declaration in the namespace under the cluster in advance.

     • Environment variables: Configure environment variables for Pods in the form of key-value pairs. Used to add environment flags to Pods or pass configuration, etc.

     • Privileged mode: Privileged mode has the same privileges for processes inside the container as for processes outside the container.

3. Click the “Deploy” button to deploy the nginx application.
