Creating DaemonSets

A DaemonSet ensures that exactly one pod runs on each eligible node in a cluster. DaemonSets are suitable for system-level applications, such as log collection and resource monitoring. DaemonSets can effectively ensure the availability of basic services in clusters.

Prerequisites

A container image has been created. You can directly use an image from a third-party container registry, or upload an image to the Container Registry (CR) service. To upload an image to CR, see Pushing and pulling images.

Creating DaemonSets on the console

In the left navigation bar, click Cluster.

Click Workload > DaemonSet. On the page that appears, click Create DaemonSet, and then configure the DaemonSet.

Configure DaemonSet information. For parameter details, see Workload configurations.

Click Confirm in the lower-right corner of the page.

Creating DaemonSets by using kubectl

tip

Before you start creating a DaemonSet by using kubectl, make sure that the following conditions are met:

The kubectl tool has been installed on your on-premises computer. For details, see Installing and configuring kubectl.

The target cluster has been connected through kubectl. For details, see Connecting to clusters.

Create the YAML file of the workload. The code of the sample file daemonset-demo.yaml is as follows:

apiVersion: apps/v1
kind: DaemonSet
metadata:
name: daemonset-demo # The name of the DaemonSet.
namespace: default # The namespace of the DaemonSet.
spec:
selector:
matchLabels:
app: demo
template:
metadata:
labels:
app: demo
spec:
containers:
- name: nginx # The name of the container.
image: doc-cn-beijing.cr.volces.com/vke/nginx-demo:v1.0 # The container image address and tag.
ports:
- containerPort: 80 # The exposed port of the container.
resources:
requests: # The container CPU and memory requests.
cpu: "500m"
memory: "1024Mi"
limits: # The resource quotas, such as the CPU limit, memory limit, and number of RDMA cards.
cpu: "1"
memory: "2Gi"
vke.volcengine.com/rdma: 2

Run the following command to create the workload.

kubectl apply -f daemonset-demo.yaml

Results

After you create the DaemonSet, you can view the status of the workload on the Workload > DaemonSet page. You can click the button in the Actions column to manage the created DaemonSet. For more operations, see Managing workloads.
