It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using <a href="https://minikube.sigs.k8s.io/docs/tutorials/multi_node/">minikube</a> or you can use one of these Kubernetes playgrounds:</p> <ul> <li><a href="https://killercoda.com/playgrounds/scenario/kubernetes">Killercoda</a></li> <li><a href="https://labs.play-with-k8s.com/">Play with Kubernetes</a></li> </ul> Your Kubernetes server must be at or later than version 1.16. To check the version, enter <code>kubectl version</code>. If you are using an older version of Kubernetes that is still supported, switch to the documentation for that version to see advice that is relevant for your cluster.</p> <!-- steps --> <h2 id="create-a-customresourcedefinition">Create a CustomResourceDefinition</h2> <p>When you create a new CustomResourceDefinition (CRD), the Kubernetes API Server creates a new RESTful resource path for each version you specify. The custom resource created from a CRD object can be either namespaced or cluster-scoped, as specified in the CRD's <code>spec.scope</code> field. As with existing built-in objects, deleting a namespace deletes all custom objects in that namespace. CustomResourceDefinitions themselves are non-namespaced and are available to all namespaces.</p> <p>For example, if you save the following CustomResourceDefinition to <code>resourcedefinition.yaml</code>:</p> <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-yaml"

Any controller can add a finalizer to any object's list of finalizers.</p> <p>The first delete request on an object with finalizers sets a value for the <code>metadata.deletionTimestamp</code> field but does not delete it. Once this value is set, entries in the <code>finalizers</code> list can only be removed. While any finalizers remain it is also impossible to force the deletion of an object.</p> <p>When the <code>metadata.deletionTimestamp</code> field is set, controllers watching the object execute any finalizers they handle and remove the finalizer from the list after they are done. It is the responsibility of each controller to remove its finalizer from the list.</p> <p>The value of <code>metadata.deletionGracePeriodSeconds</code> controls the interval between polling updates.</p> <p>Once the list of finalizers is empty, meaning all finalizers have been executed, the resource is deleted by Kubernetes.</p> <h3 id="validation">Validation</h3> <p>Custom resources are validated via <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md#schemaObject">OpenAPI v3 schemas</a>, by x-kubernetes-validations when the <a href="#validation-rules">Validation Rules feature</a> is enabled, and you can add additional validation using <a href="/docs/reference/access-authn-authz/admission-controllers/#validatingadmissionwebhook">admission webhooks</a>.</p> <p>Additionally, the following restrictions are applied to the schema:</p> <ul> <li> <p>These fields cannot be set:</p> <ul> <li><code>definitions</code>,</li> <li><code>dependencies</code>,</li> <li><code>deprecated</code>,</li> <li><code>discriminator</code>,</li> <li><code>id</code>,</li> <li><code>patternProperties</code>,</li> <li><code>readOnly</code>,</li> <li><code>writeOnly</code>,</li> <li><code>xml</code>,</li> <li><code>$ref</code>.</li> </ul> </li> <li> <p>The field <code>uniqueItems</code> cannot be set to <code>true</code>.</p> </li> <li> <p>The field <code>additionalProperties</code> cannot be set to <code>false</code>.</p> </li> <li> <p>The field <code>additionalProperties</code> is mutually exclusive with <code>properties</code>.</p> </li> </ul> <p>The <code>x-kubernetes-validations</code> extension can be used to validate custom resources using <a href="https://github.com/google/cel-spec">Common Expression Language (CEL)</a> expressions when the <a href="#validation-rules">Validation rules</a> feature is enabled and the CustomResourceDefinition schema is a <a href="#specifying-a-structural-schema">structural schema</a>.</p> <p>Refer to the <a href="#specifying-a-structural-schema">structural schemas</a> section for other restrictions and CustomResourceDefinition features.</p> <p>The schema is defined in the CustomResourceDefinition.

The API server is willing to accept updates to resources that are not valid after the update, provided that each part of the resource that failed to validate was not changed by the update operation. In other words, any invalid part of the resource that remains invalid must have already been wrong. You cannot use this mechanism to update a valid resource so that it becomes invalid.</p> <p>This feature allows authors of CRDs to confidently add new validations to the OpenAPIV3 schema under certain conditions. Users can update to the new schema safely without bumping the version of the object or breaking workflows.</p> <p>While most validations placed in the OpenAPIV3 schema of a CRD support ratcheting, there are a few exceptions. The following OpenAPIV3 schema validations are not supported by ratcheting under the implementation in Kubernetes 1.28 and if violated will continue to throw an error as normally:</p> <ul> <li>Quantors <ul> <li><code>allOf</code></li> <li><code>oneOf</code></li> <li><code>anyOf</code></li> <li><code>not</code></li> <li>any validations in a descendent of one of these fields</li> </ul> </li> <li><code>x-kubernetes-validations</code> For Kubernetes 1.28, CRD validation rules](#validation-rules) are ignored by ratcheting. This may change in later Kubernetes releases.</li> <li><code>x-kubernetes-list-type</code> Errors arising from changing the list type of a subschema will not be ratcheted. For example adding <code>set</code> onto a list with duplicates will always result in an error.</li> <li><code>x-kubernetes-map-keys</code> Errors arising from changing the map keys of a list schema will not be ratcheted.</li> <li><code>required</code> Errors arising from changing the list of required fields will not be ratcheted.</li> <li><code>properties</code> Adding/removing/modifying the names of properties is not ratcheted, but changes to validations in each properties' schemas and subschemas may be ratcheted if the name of the property stays the same.</li> <li><code>additionalProperties</code> To remove a previously specified <code>additionalProperties</code> validation will not be ratcheted.</li> </ul> <h3 id="validation-rules">Validation rules</h3> <div style="margin-top: 10px; margin-bottom: 10px;"> <b>FEATURE STATE:</b> <code>Kubernetes v1.25 [beta]</code> </div> <p>Validation rules are in beta since 1.25 and the <code>CustomResourceValidationExpressions</code> <a href="/docs/reference/command-line-tools-reference/feature-gates/">feature gate</a> is enabled by default to validate custom resource based on <em>validation rules</em>.

For example:</p> <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-yaml" data-lang="yaml"><span style="display:flex;"><span><span style="color:#008000;font-weight:bold">x-kubernetes-validations</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"></span>- <span style="color:#008000;font-weight:bold">rule</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#34;self.x &lt;= self.maxLimit&#34;</span><span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">messageExpression</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#39;&#34;x exceeded max limit of &#34; + string(self.maxLimit)&#39;</span><span style="color:#bbb"> </span></span></span></code></pre></div><p>Keep in mind that CEL string concatenation (<code>+</code> operator) does not auto-cast to string. If you have a non-string scalar, use the <code>string(&lt;value&gt;)</code> function to cast the scalar to a string like shown in the above example.</p> <p><code>messageExpression</code> must evaluate to a string, and this is checked while the CRD is being written. Note that it is possible to set <code>message</code> and <code>messageExpression</code> on the same rule, and if both are present, <code>messageExpression</code> will be used. However, if <code>messageExpression</code> evaluates to an error, the string defined in <code>message</code> will be used instead, and the <code>messageExpression</code> error will be logged. This fallback will also occur if the CEL expression defined in <code>messageExpression</code> generates an empty string, or a string containing line breaks.</p> <p>If one of the above conditions are met and no <code>message</code> has been set, then the default validation failure message will be used instead.</p> <p><code>messageExpression</code> is a CEL expression, so the restrictions listed in <a href="#resource-use-by-validation-functions">Resource use by validation functions</a> apply. If evaluation halts due to resource constraints during <code>messageExpression</code> execution, then no further validation rules will be executed.</p> <p>Setting <code>messageExpression</code> is optional.</p> <h4 id="field-message">The <code>message</code> field</h4> <p>If you want to set a static message, you can supply <code>message</code> rather than <code>messageExpression</code>. The value of <code>message</code> is used as an opaque error string if validation fails.</p> <p>Setting <code>message</code> is optional.</p> <h4 id="field-reason">The <code>reason</code> field</h4> <p>You can add a machine-readable validation failure reason within a <code>validation</code>, to be returned whenever a request fails this validation rule.</p> <p>For example:</p> <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-yaml" data-lang="yaml"><span style="display:flex;"><span><span style="color:#008000;font-weight:bold">x-kubernetes-validations</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"></span>- <span style="color:#008000;font-weight:bold">rule</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#34;self.x &lt;= self.maxLimit&#34;</span><span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">reason</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#34;FieldValueInvalid&#34;</span><span style="color:#bbb"> </span></span></span></code></pre></div><p>The HTTP status code returned to the caller will match the reason of the first failed validation rule.

If not set or unknown reasons, default to use &quot;FieldValueInvalid&quot;.</p> <p>Setting <code>reason</code> is optional.</p> <h4 id="field-field-path">The <code>fieldPath</code> field</h4> <p>You can specify the field path returned when the validation fails.</p> <p>For example:</p> <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-yaml" data-lang="yaml"><span style="display:flex;"><span><span style="color:#008000;font-weight:bold">x-kubernetes-validations</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"></span>- <span style="color:#008000;font-weight:bold">rule</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#34;self.foo.test.x &lt;= self.maxLimit&#34;</span><span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">fieldPath</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#34;.foo.test.x&#34;</span><span style="color:#bbb"> </span></span></span></code></pre></div><p>In the example above, the validation checks the value of field <code>x</code> should be less than the value of <code>maxLimit</code>. If no <code>fieldPath</code> specified, when validation fails, the fieldPath would be default to wherever <code>self</code> scoped. With <code>fieldPath</code> specified, the returned error will have <code>fieldPath</code> properly refer to the location of field <code>x</code>.</p> <p>The <code>fieldPath</code> value must be a relative JSON path that is scoped to the location of this x-kubernetes-validations extension in the schema. Additionally, it should refer to an existing field within the schema. For example when validation checks if a specific attribute <code>foo</code> under a map <code>testMap</code>, you could set <code>fieldPath</code> to <code>&quot;.testMap.foo&quot;</code> or <code>.testMap['foo']'</code>. If the validation requires checking for unique attributes in two lists, the fieldPath can be set to either of the lists. For example, it can be set to <code>.testList1</code> or <code>.testList2</code>. It supports child operation to refer to an existing field currently. Refer to <a href="/docs/reference/kubectl/jsonpath/">JSONPath support in Kubernetes</a> for more info. The <code>fieldPath</code> field does not support indexing arrays numerically.</p> <p>Setting <code>fieldPath</code> is optional.</p> <h4 id="available-validation-functions">Validation functions</h4> <p>Functions available include:</p> <ul> <li>CEL standard functions, defined in the <a href="https://github.com/google/cel-spec/blob/v0.7.0/doc/langdef.md#list-of-standard-definitions">list of standard definitions</a></li> <li>CEL standard <a href="https://github.com/google/cel-spec/blob/v0.7.0/doc/langdef.md#macros">macros</a></li> <li>CEL <a href="https://pkg.go.dev/github.com/google/cel-go@v0.11.2/ext#Strings">extended string function library</a></li> <li>Kubernetes <a href="https://pkg.go.dev/k8s.io/apiextensions-apiserver@v0.24.0/pkg/apiserver/schema/cel/library#pkg-functions">CEL extension library</a></li> </ul> <h4 id="transition-rules">Transition rules</h4> <p>A rule that contains an expression referencing the identifier <code>oldSelf</code> is implicitly considered a <em>transition rule</em>.

It remains possible to check if a value has been added or removed by placing a transition rule on the parent node. Transition rules are never applied to custom resource creation. When placed on an optional field, a transition rule will not apply to update operations that set or unset the field.</p> </li> <li> <p>The path to the schema node being validated by a transition rule must resolve to a node that is comparable between the old object and the new object. For example, list items and their descendants (<code>spec.foo[10].bar</code>) can't necessarily be correlated between an existing object and a later update to the same object.</p> </li> </ul> <p>Errors will be generated on CRD writes if a schema node contains a transition rule that can never be applied, e.g. &quot;<em>path</em>: update rule <em>rule</em> cannot be set on schema because the schema or its parent schema is not mergeable&quot;.</p> <p>Transition rules are only allowed on <em>correlatable portions</em> of a schema. A portion of the schema is correlatable if all <code>array</code> parent schemas are of type <code>x-kubernetes-list-type=map</code>; any <code>set</code>or <code>atomic</code>array parent schemas make it impossible to unambiguously correlate a <code>self</code> with <code>oldSelf</code>.</p> <p>Here are some examples for transition rules:</p> <table><caption style="display: none;">Transition rules examples</caption> <thead> <tr> <th>Use Case</th> <th>Rule</th> </tr> </thead> <tbody> <tr> <td>Immutability</td> <td><code>self.foo == oldSelf.foo</code></td> </tr> <tr> <td>Prevent modification/removal once assigned</td> <td><code>oldSelf != 'bar' || self == 'bar'</code> or <code>!has(oldSelf.field) || has(self.field)</code></td> </tr> <tr> <td>Append-only set</td> <td><code>self.all(element, element in oldSelf)</code></td> </tr> <tr> <td>If previous value was X, new value can only be A or B, not Y or Z</td> <td><code>oldSelf != 'X' || self in ['A', 'B']</code></td> </tr> <tr> <td>Monotonic (non-decreasing) counters</td> <td><code>self &gt;= oldSelf</code></td> </tr> </tbody> </table> <h4 id="resource-use-by-validation-functions">Resource use by validation functions</h4> <p>When you create or update a CustomResourceDefinition that uses validation rules, the API server checks the likely impact of running those validation rules. If a rule is estimated to be prohibitively expensive to execute, the API server rejects the create or update operation, and returns an error message. A similar system is used at runtime that observes the actions the interpreter takes. If the interpreter executes too many instructions, execution of the rule will be halted, and an error will result. Each CustomResourceDefinition is also allowed a certain amount of resources to finish executing all of its validation rules. If the sum total of its rules are estimated at creation time to go over that limit, then a validation error will also occur.</p> <p>You are unlikely to encounter issues with the resource budget for validation if you only specify rules that always take the same amount of time regardless of how large their input is. For example, a rule that asserts that <code>self.foo == 1</code> does not by itself have any risk of rejection on validation resource budget groups. But if <code>foo</code> is a string and you define a validation rule <code>self.foo.contains(&quot;someString&quot;)</code>, that rule takes longer to execute depending on how long <code>foo</code> is. Another example would be if <code>foo</code> were an array, and you specified a validation rule <code>self.foo.all(x, x &gt; 5)</code>. The cost system always assumes the worst-case scenario if a limit on the length of <code>foo</code> is not given, and this will happen for anything that can be iterated over (lists, maps, etc.).</p> <p>Because of this, it is considered best practice to put a limit via <code>maxItems</code>, <code>maxProperties</code>, and <code>maxLength</code> for anything that will be processed in a validation rule in order to prevent validation errors during cost estimation. For example, given this schema with one rule:</p> <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-yaml" data-lang="yaml"><span style="display:flex;"><span><span style="color:#008000;font-weight:bold">openAPIV3Schema</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">type</span>:<span style="color:#bbb"> </span>object<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">properties</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">foo</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">type</span>:<span style="color:#bbb"> </span>array<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">items</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">type</span>:<span style="color:#bbb"> </span>string<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span><span style="color:#008000;font-weight:bold">x-kubernetes-validations</span>:<span style="color:#bbb"> </span></span></span><span style="display:flex;"><span><span style="color:#bbb"> </span>- <span style="color:#008000;font-weight:bold">rule</span>:<span style="color:#bbb"> </span><span style="color:#b44">&#34;self.all(x, x.contains(&#39;a string&#39;))&#34;</span><span style="color:#bbb"> </span></span></span></code></pre></div><p>then the API server rejects this rule on validation budget grounds with error:</p> <pre tabindex="0"><code>spec.validation.openAPIV3Schema.properties[spec].properties[foo].x-kubernetes-validations[0].rule: Forbidden: CEL rule exceeded budget by more than 100x (try simplifying the rule, or adding maxItems, maxProperties, and maxLength where arrays, maps, and strings are used) </code></pre><p>The rejection happens because <code>self.all</code> implies calling <code>contains()</code> on every string in <code>foo</code>, which in turn will check the given string to see if it contains <code>'a string'</code>.

id="publish-validation-schema-in-openapi">Publish Validation Schema in OpenAPI</h3> <p>CustomResourceDefinition <a href="#validation">OpenAPI v3 validation schemas</a> which are <a href="#specifying-a-structural-schema">structural</a> and <a href="#field-pruning">enable pruning</a> are published as <a href="/docs/concepts/overview/kubernetes-api/#openapi-and-swagger-definitions">OpenAPI v3</a> and OpenAPI v2 from Kubernetes API server. It is recommended to use the OpenAPI v3 document as it is a lossless representation of the CustomResourceDefinition OpenAPI v3 validation schema while OpenAPI v2 represents a lossy conversion.</p> <p>The <a href="/docs/reference/kubectl/">kubectl</a> command-line tool consumes the published schema to perform client-side validation (<code>kubectl create</code> and <code>kubectl apply</code>), schema explanation (<code>kubectl explain</code>) on custom resources. The published schema can be consumed for other purposes as well, like client generation or documentation.</p> <h4 id="compatibility-with-openapi-v2">Compatibility with OpenAPI V2</h4> <p>For compatibility with OpenAPI V2, the OpenAPI v3 validation schema performs a lossy conversion to the OpenAPI v2 schema. The schema show up in <code>definitions</code> and <code>paths</code> fields in the <a href="/docs/concepts/overview/kubernetes-api/#openapi-and-swagger-definitions">OpenAPI v2 spec</a>.</p> <p>The following modifications are applied during the conversion to keep backwards compatibility with kubectl in previous 1.13 version. These modifications prevent kubectl from being over-strict and rejecting valid OpenAPI schemas that it doesn't understand. The conversion won't modify the validation schema defined in CRD, and therefore won't affect <a href="#validation">validation</a> in the API server.</p> <ol> <li> <p>The following fields are removed as they aren't supported by OpenAPI v2.</p> <ul> <li>The fields <code>allOf</code>, <code>anyOf</code>, <code>oneOf</code> and <code>not</code> are removed</li> </ul> </li> <li> <p>If <code>nullable: true</code> is set, we drop <code>type</code>, <code>nullable</code>, <code>items</code> and <code>properties</code> because OpenAPI v2 is not able to express nullable. To avoid kubectl to reject good objects, this is necessary.</p> </li> </ol> <h3 id="additional-printer-columns">Additional printer columns</h3> <p>The kubectl tool relies on server-side output formatting. Your cluster's API server decides which columns are shown by the <code>kubectl get</code> command. You can customize these columns for a CustomResourceDefinition. The following example adds the <code>Spec</code>, <code>Replicas</code>, and <code>Age</code> columns.</p> <p>Save the CustomResourceDefinition to <code>resourcedefinition.yaml</code>:</p> <div
