  5. DESCRIPTION:
  6.      Deployment enables declarative updates for Pods and ReplicaSets.
  8. FIELDS:
  9.    apiVersion    <string>
  10.      APIVersion defines the versioned schema of this representation of an
  11.      object. Servers should convert recognized schemas to the latest internal

  15.    kind    <string>
  16.      Kind is a string value representing the REST resource this object
  17.      represents. Servers may infer this from the endpoint the client submits
  18.      requests to. Cannot be updated. In CamelCase. More info:
  19.      https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
  21.    metadata    <Object>
  22.      Standard object metadata.
  24.    spec    <Object>
  25.      Specification of the desired behavior of the Deployment.
  27.    status    <Object>
  28.      Most recently observed status of the Deployment.
  31. [root@k8s-5-138 pod_template]# kubectl explain ConfigMap
  32. KIND:     ConfigMap
  33. VERSION:  v1
  35. DESCRIPTION:
  36.      ConfigMap holds configuration data for pods to consume.
  38. FIELDS:
  39.    apiVersion    <string>
  40.      APIVersion defines the versioned schema of this representation of an
  41.      object. Servers should convert recognized schemas to the latest internal
  42.      value, and may reject unrecognized values. More info:
  43.      https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
  45.    binaryData    <map[string]string>
  46.      BinaryData contains the binary data. Each key must consist of alphanumeric
  47.      characters, '-', '_' or '.'. BinaryData can contain byte sequences that are
  48.      not in the UTF-8 range. The keys stored in BinaryData must not overlap with
  49.      the ones in the Data field, this is enforced during validation process.
  50.      Using this field will require 1.10+ apiserver and kubelet.
  52.    data    <map[string]string>
  53.      Data contains the configuration data. Each key must consist of alphanumeric
  54.      characters, '-', '_' or '.'. Values with non-UTF-8 byte sequences must use
  55.      the BinaryData field. The keys stored in Data must not overlap with the
  56.      keys in the BinaryData field, this is enforced during validation process.
  58.    immutable    <boolean>
  59.      Immutable, if set to true, ensures that data stored in the ConfigMap cannot
  60.      be updated (only object metadata can be modified). If not set to true, the
  61.      field can be modified at any time. Defaulted to nil. This is an alpha field
  62.      enabled by ImmutableEphemeralVolumes feature gate.
  64.    kind    <string>
  65.      Kind is a string value representing the REST resource this object
