Create a pod with an x86 instance type - Elastic Container Instance

This topic describes how to specify Elastic Compute Service (ECS) instance types of the x86 architecture to create an Elastic Container Instance (ECI) pod.

Instance types

ECS instance types of the x86 architecture fall into two categories based on whether they are suitable for enterprise scenarios: enterprise-level families and shared families.

Enterprise-level x86 computing instance families

x86-based instance types are built on the x86 architecture. Each vCPU corresponds to a hyper-thread of a processor core. They deliver stable performance and are suitable for various types and sizes of enterprise applications, database systems, video encoding and decoding, and data analytics.

Category	Enterprise-level x86 instance family
General-purpose	g9ae, g9a, g9i, g8a, g8i, g7a, g7, g6e, g6a, g6, g5, sn2ne, sn2
Compute-optimized	c9ae, c9a, c9i, c8a, c8i, c7a, c7, c6e, c6a, c6, c5, sn1ne, sn1
Memory-optimized	r9ae, r9a, r9i, r8a, r8i, r7a, r7, r6e, r6a, r6, r5, se1ne, se1
General-purpose computing	u2a, u2i, u1
Compute-intensive	ic5
High clock speed	hfg8i, hfg7, hfg6, hfg5 hfc8i, hfc7, hfc6, hfc5 hfr8i, hfr7
Big data	d1, d1ne
Local SSD	i2, i2g
Memory-enhanced	re6

Shared x86 computing instance families

Shared instance types are designed for small and medium-sized websites or individual developers. Compared with enterprise-level instance types, shared instance types use shared resources. This means the computing performance of an instance cannot be guaranteed, but the cost is lower.

Note

Some of the preceding instance families use local disks, such as i2 and d1ne. To mount local disks, you must configure a volume. For more information, see ECS instance types that use a local disk.

For more information about ECS instance types, see the following topics:

Configurations

You can specify ECS instance types by adding the k8s.aliyun.com/eci-use-specs annotation to the pod metadata. The following is a YAML example:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: test
  labels:
    app: test
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      name: nginx-test
      labels:
        app: nginx
        alibabacloud.com/eci: "true" 
      annotations:
        k8s.aliyun.com/eci-use-specs: ecs.c6.large,ecs.c5.large  # Specify up to five ECS instance types as needed.
    spec:
      containers:
      - name: nginx
        image: registry.cn-shanghai.aliyuncs.com/eci_open/nginx:1.14.2
        ports:
        - containerPort: 80
