Cloud provider — GCP: Custom Resources

Parameters of a group of GCP Instances used by machine-controller-manager (the node-manager module).

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

• specobject

  Required value

  • spec.additionalLabelsobject

    Additional labels.

    More info…

    Example:

    project: cms-production
    severity: critical
    

  • spec.additionalNetworkTagsarray of strings

    The list of additional tags.

    For example, you can use tags to apply firewall rules to instances. The detailed description of network tags is available in the official documentation.

  • 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 machineType 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 (a2-highgpu-8g, c2-standard-8, 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.disableExternalIPboolean

    Defines whether to disable external ip for an instance or not. True means that an instance is created without external ip

  • spec.diskSizeGbinteger

    Instance’s root disk size in gibibytes.

    Default: 50

    Example:

    diskSizeGb: 20
    

  • spec.diskTypestring

    Instance’s disk type.

    Default: "pd-standard"

    Allowed values: pd-standard, pd-ssd

    Example:

    diskType: pd-ssd
    

  • spec.imagestring

    Not required value.

    Image to use while provisioning GCP servers.

    You can find a list of images in the documentation.

    Caution! Currently, only Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Centos 7, Centos 8, Centos 9, Debian 9, Debian 10, Debian 11 are supported and tested to work.

    Example:

    image: https://www.googleapis.com/compute/v1/projects/ubuntu-os-cloud/global/images/ubuntu-1804-bionic-v20190911
    

  • spec.machineTypestring

    Required value

    Machine type of GCP instance.

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

    GCP lets you specify a custom amount of resources (CPU and RAM), e.g., custom-8-40960 or n2-custom-8-40960.

    Example:

    machineType: n1-standard-4
    

  • spec.preemptibleboolean

    Should instances be preemptible.

    Default: false
