AWS EKS使用Cloudwatch Container Insights

[!TIP]

文档编写时间：2021-12-29

安装Container Insights作为DaemonSet

为工作节点附加Cloudwatch权限，$ROLE_NAME为集群节点的IAM角色

aws iam attach-role-policy \
  --role-name $ROLE_NAME \
  --policy-arn arn:aws:iam::aws:policy/CloudWatchAgentServerPolicy

部署Container Insights，test-eks为集群名称，${AWS_REGION}填写EKS集群所在区域

curl -s https://raw.githubusercontent.com/aws-samples/amazon-cloudwatch-container-insights/latest/k8s-deployment-manifest-templates/deployment-mode/daemonset/container-insights-monitoring/quickstart/cwagent-fluentd-quickstart.yaml | sed "s/{{cluster_name}}/test-eks/;s/{{region_name}}/${AWS_REGION}/" | kubectl apply -f -

## output
