Cloud provider — AWS: Custom Resources

Parameters of the AWS instance used by machine-controller-manager (the node-manager modile).

The CloudInstanceClass resource of the node-manager module refers to this resource.

• specobject

  Required value

  • spec.additionalSecurityGroupsarray of strings

    The additional security groups to add to provisioned instances of the specific InstanceClass.

  • spec.additionalTagsobject

    Extra AWS tags for instances in addition to AWSClusterConfiguration.tags.

  • spec.amistring

    The Amazon Machine Image (AMI ID) to use in provisioned instances.

    If omitted, the AMI defined in the masterNodeGroup.instanceClass.ami parameter of the AWSClusterConfiguration resource is used.

    Here is how you can find the required AMI (each region has its own set of AMIs):

    aws ec2 --region <REGION> describe-images \
    --filters 'Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-2020*' | \
    jq '.Images[].ImageId'
    

    Example:

    ami: ami-040a1551f9c9d11ad
    

  • spec.capacityDeprecatedobject

    Deprecated: the parameter is no longer used. Deckhouse is using parameters from the cloud for passed instance type.

    Instance capacity for non-standard instance types (the instanceTypes parameter).

    Cluster-autoscaler uses the parameter for scheduling only when there are no nodes in NodeGroup yet (if minPerZone equal to 0). If there are already nodes in the NodeGroup, then cluster-autoscaler uses the actual node capacity (CPU, memory) when planning, and does not use the capacity parameter.

    The parameter must be specified only for non-standard instance types. Info about the capacity of standard instance types (t2.micro, m6a.12xlarge, etc.) is embedded in Deckhouse.

    • spec.capacity.cpuinteger or string

      Required value

      Node vCPU resources.

      Pattern: ^[0-9]+m?$

      Example:

      cpu: 1000m
      

    • spec.capacity.memoryinteger or string

      Required value

      Node memory resources.

      Pattern: ^[0-9]+(\.[0-9]+)?(E|P|T|G|M|k|Ei|Pi|Ti|Gi|Mi|Ki)?$

      Example:

      memory: 1500Mi
      

  • spec.diskSizeGbinteger

    Instance root disk size in gibibytes.

    Default: 20

    Example:

    diskSizeGb: 20
    

  • spec.diskTypestring

    Instance EBS disk type.

    Default: "gp2"

    Example:

    diskType: gp2
    

  • spec.instanceTypestring

    Required value

    Instance type of AWS instance.

    Caution! Ensure that this type is present in all zones specified in the zones parameter.

    Example:

    instanceType: t3.large
    

  • spec.iopsstring

    IOPS rate for io1 diskType

    Example:

    iops: '500'
    

  • spec.spotboolean

    Whether to create Spot Instances with minimum hourly price with which Instances will run.
