Creating an Image Snapshot

Creating an Image Snapshot Using YAML

1. Log in to the CCI 2.0 console.
2. In the navigation pane, choose Image Acceleration.
3. Click Create from YAML in the upper right corner.

   In the following example, an image snapshot named my-imagesnapshot will be created.

   apiVersion: cci/v2
   kind: ImageSnapshot
   metadata:
     name: 'my-imagesnapshot'
     labels: cci.io/image-snapshot-architecture: "amd64"    #(New) specifies the CPU architecture.
   spec:
     buildingConfig:
       namespace: test
       eipID: 3cxxxxe0-xxxx-xxxx-xxxx-8xxxxf3xxxx4
     imageSnapshotSize: 30
     ttlDaysAfterCreated: 7
     images:
       - image: 'nginx:latest'
     registries:
       - imagePullSecret: imagepull-secret
         server: xxxxx.myhuaweicloud.com
         plainHTTP: true

   Table 1 Parameter description

   Field	Type	Mandatory	Example Value	Description
   .metadata.name	String	Yes	my-imagesnapshot	Image snapshot name.
   .spec.images.image	String	Yes	nginx:latest	Image used to create an image snapshot. Up to 10 images can be added.
   .spec.registries.server	String	Yes	xxxxx.myhuaweicloud.com	Image repository address without the http:// or https:// prefix.
   .spec.registries.imagePullSecret	String	No	imagepull-secret	Secret for accessing the image repository. A maximum of 10 credentials can be added.
   .spec.registries.plainHTTP	Boolean	No	true	If the self-managed image repository address uses the HTTP protocol, set the value to true, or the image fails to be pulled due to different protocols. The default value is false.
   .spec.registries.insecureSkipVerify	Boolean	No	true	If the self-managed image repository address uses a self-issued certificate, set the value to true to skip certificate authentication, or the image fails to be pulled due to a certificate authentication failure. The default value is false.
   .spec.buildingConfig.namespace	String	Yes	test	Namespace. During image snapshot creation, a pod will be created in this namespace.
   .spec.buildingConfig.eipID	String	No	3cxxxxe0-xxxx-xxxx-xxxx-8xxxxf3xxxx4	EIP used for pulling images over the public network
   .spec.buildingConfig.autoCreateEIP	Boolean	No	true	Whether to automatically assign an EIP for the pod that is used for creating the image snapshot. If eipId is specified, autoCreateEIP is ignored. If autoCreateEIP is set to true, you need to specify the EIP configuration using autoCreateEIPAttribute.
   .spec.buildingConfig.autoCreateEIPAttribute.bandwidthChargeMode	String	No	bandwidth	Whether the bandwidth is billed by traffic or bandwidth. The value can be traffic or bandwidth. If this parameter is left blank or is an empty string, default value bandwidth is used. For IPv6 addresses, the default parameter value is bandwidth outside China and traffic in China.
   .spec.buildingConfig.autoCreateEIPAttribute.bandwidthSize	Integer	No	1000	Bandwidth. If billing by bandwidth is selected, the value ranges from 1 Mbit/s to 2,000 Mbit/s by default. If billing by traffic is selected, the value ranges from 1 Mbit/s to 300 Mbit/s by default.
   .spec.buildingConfig.autoCreateEIPAttribute.type	String	No	5_bgp	EIP type. The value can be 5_bgp (dynamic BGP), 5_sbgp (static BGP), or 5_youxuanbgp (premium BGP).
   .spec.buildingConfig.autoCreateEIPAttribute.ipVersion	Integer	No	4	EIP version. 4 indicates IPv4 EIP. If this parameter is left blank or is an empty string, an IPv4 EIP is assigned by default.
   .spec.buildingConfig.TimeoutMinutes	Integer	No	1440	Timeout interval for creating a snapshot, in minutes. The value is an integer from 30 (30 minutes) to 10080 (one week). The default value is 1440, indicating one day.
   .spec.ttlDaysAfterCreated	Integer	No	7	Retention period of the image snapshot, in days. Expired image snapshots will be deleted. The default value is 0, indicating that the snapshot never expires. When an image snapshot is used by a workload or pod, this image snapshot remains valid from the time when it was used by the workload or pod until the configured retention period ends. NOTE: After an image snapshot expires, it still occupies the quota. You need to periodically review and delete expired image snapshots.
   .spec.imageSnapshotSize	Integer	No	30	Image snapshot size, in GiB. The default value is 20.

   In addition to basic parameters, you can add labels to specify the CPU architecture used for creating an image snapshot. For details about the label, see Table 2.

   Table 2 Label description

   Field	Type	Mandatory	Example Value	Description
   .labels.cci.io/image-snapshot-architecture	String	No	amd64	CPU architecture of the image. The options are as follows: amd64 (default value) NOTE: When specifying the architecture, check whether the pod type is available at the site. amd64: x86 general computing pods
