Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Google Container Engine Chef Cookbook

This cookbook provides the built-in types and services for Chef to manage
Google Container Engine resources, as native Chef types.

Requirements

Platforms

Supported Operating Systems

This cookbook was tested on the following operating systems:

  • RedHat 6, 7
  • CentOS 6, 7
  • Debian 7, 8
  • Ubuntu 12.04, 14.04, 16.04, 16.10

  action :serviceaccount
  path ENV['CRED_PATH'] # e.g. '/path/to/my_account.json'
  scopes [
    'https://www.googleapis.com/auth/cloud-platform'
  ]
end

  credential 'mycred'
end

Credentials

All Google Cloud Platform cookbooks use an unified authentication mechanism,
provided by the google-gauth cookbook. Don't worry, it is automatically
installed when you install this module.

Example

gauth_credential 'mycred' do
  action :serviceaccount
  path ENV['CRED_PATH'] # e.g. '/path/to/my_account.json'
  scopes [
    'https://www.googleapis.com/auth/cloud-platform'
  ]
end

For complete details of the authentication cookbook, visit the
google-gauth cookbook documentation.

Resources

  • gcontainer_cluster - A Google Container Engine cluster.
  • gcontainer_node_pool - NodePool contains the name and configuration for a cluster's node pool. Node pools are a set of nodes (i.e. VM's), with a common configuration and specification, under the control of the cluster master. They may have a set of Kubernetes labels applied to them, which may be used to reference them during pod scheduling. They may also be resized up or down, to accommodate the workload.
  • gcontainer_kube_config - Generates a compatible Kuberenetes '.kube/config' file

gcontainer_cluster

A Google Container Engine cluster.

Example

gcontainer_cluster "mycluster-#{ENV['cluster_id']}" do
  action :create
  initial_node_count 2
  master_auth(
    username: 'cluster_admin',
    password: 'my-secret-password'
  )
  node_config(
    machine_type: 'n1-standard-4', # we want 4-cores for our cluster

Actions

  • create - Converges the gcontainer_cluster resource into the final state described within the block. If the resource does not exist, Chef will attempt to create it.
  • delete - Ensures the gcontainer_cluster resource is not present. If the resource already exists Chef will attempt to delete it.

Properties

  • name -
    The name of this cluster. The name must be unique within this project
    and zone, and can be up to 40 characters. Must be Lowercase letters,
    numbers, and hyphens only. Must start with a letter. Must end with a
    number or a letter.

  • description -
    An optional description of this cluster.

  • initial_node_count -
    Required. The number of nodes to create in this cluster. You must ensure that
    your Compute Engine resource quota is sufficient for this number of
    instances. You must also have available firewall and routes quota. For
    requests, this field should only be used in lieu of a "nodePool"
    object, since this configuration (along with the "nodeConfig") will be
    used to create a "NodePool" object with an auto-generated name. Do not
    use this and a nodePool at the same time.

  • node_config -
    Parameters used in creating the cluster's nodes.
    For requests, this field should only be used in lieu of a "nodePool"
    object, since this configuration (along with the "initialNodeCount")
    will be used to create a "NodePool" object with an auto-generated
    name. Do not use this and a nodePool at the same time. For responses,
    this field will be populated with the node configuration of the first
    node pool. If unspecified, the defaults are used.

  • node_config/machine_type
    The name of a Google Compute Engine machine type (e.g.
    n1-standard-1). If unspecified, the default machine type is
    n1-standard-1.

  • node_config/disk_size_gb
    Size of the disk attached to each node, specified in GB. The
    smallest allowed disk size is 10GB. If unspecified, the default
    disk size is 100GB.

  • node_config/oauth_scopes
    The set of Google API scopes to be made available on all of the
    node VMs under the "default" service account.
    The following scopes are recommended, but not required, and by
    default are not included:
    https://www.googleapis.com/auth/compute is required for mounting
    persistent storage on your nodes.
    https://www.googleapis.com/auth/devstorage.read_only is required
    for communicating with gcr.io (the Google Container Registry).
    If unspecified, no scopes are added, unless Cloud Logging or Cloud
    Monitoring are enabled, in which case their required scopes will
    be added.

  • node_config/service_account
    The Google Cloud Platform Service Account to be used by the node
    VMs. If no Service Account is specified, the "default" service
    account is used.

  • node_config/metadata
    The metadata key/value pairs assigned to instances in the cluster.
    Keys must conform to the regexp [a-zA-Z0-9-_]+ and be less than
    128 bytes in length. These are reflected as part of a URL in the
    metadata server. Additionally, to avoid ambiguity, keys must not
    conflict with any other metadata keys for the project or be one of
    the four reserved keys: "instance-template", "kube-env",
    "startup-script", and "user-data"
    Values are free-form strings, and only have meaning as interpreted
    by the image running in the instance. The only restriction placed
    on them is that each value's size must be less than or equal to 32
    KB.
    The total size of all keys and values must be less than 512 KB.
    An object containing a list of "key": value pairs.
    Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

  • node_config/image_type
    The image type to use for this node. Note that for a given image
    type, the latest version of it will be used.

  • node_config/labels
    The map of Kubernetes labels (key/value pairs) to be applied to
    each node. These will added in addition to any default label(s)
    that Kubernetes may apply to the node. In case of conflict in
    label keys, the applied set may differ depending on the Kubernetes
    version -- it's best to assume the behavior is undefined and
    conflicts should be avoided. For more information, including usage
    and the valid values, see:
    http://kubernetes.io/v1.1/docs/user-guide/labels.html
    An object containing a list of "key": value pairs.
    Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

    https://cloud.google.com/compute/docs/disks/local-ssd#local_ssd_limits
    for more information.

  • node_config/tags
    The list of instance tags applied to all nodes. Tags are used to
    identify valid sources or targets for network firewalls and are
    specified by the client during cluster or node pool creation. Each
    tag within the list must comply with RFC1035.

  • node_config/preemptible
