// DepProvider is a dependency provider.
//
// The instances it returns are either
// - old implementations backed by k8sdeps code,
// - new implementations backed by kyaml code.
//
// History:
//
// kubectl depends on k8s.io code, and at the time of writing, so
// does kustomize. Code that imports k8s.io/api* cannot be imported
// back into k8s.io/*, yet kustomize appears inside k8s.io/kubectl.
//
// To allow kustomize to appear inside kubectl, yet still be developed
// outside kubectl, the kustomize code was divided into the following
// packages
//
// api/
// k8sdeps/ (and internal/ks8deps/)
// ifc/
// krusty/
// everythingElse/
//
// with the following rules:
//
// - Only k8sdeps/ may import k8s.io/api*.
//
// - Only krusty/ (and its internals) may import k8sdeps/.
// I.e., ifc/ and everythingElse/ must not
// import k8sdeps/ or k8s.io/api*.
//
// - Code in krusty/ may use code in k8sdeps/ to create
// objects then inject said objects into
// everythingElse/ behind dependency neutral interfaces.
//
// The idea was to periodically copy, not import, the large k8sdeps/
// tree (plus a snippet from krusty/kustomizer.go) into the kubectl
// codebase via a large PR, and have kubectl depend on the rest via
// normal importing.
//
// Over 2019, however, kubectl underwent large changes including
// a switch to Go modules, and a concerted attempt to extract kubectl
// from the k8s repo. This made large kustomize integration PRs too
// intrusive to review.
//
// In 2020, kubectl is based on Go modules, and almost entirely
// extracted from the k8s.io repositories, and further the kyaml
// library has a appeared as a viable replacement to k8s.io/api*
// KRM manipulation code.
//
// The new plan is to eliminate k8sdeps/ entirely, along with its
// k8s.io/api* dependence, allowing kustomize code to be imported
// into kubectl via normal Go module imports. Then the kustomize API
// code can then move into the github.com/kubernetes-sigs/cli-utils
// repo. The kustomize CLI in github.com/kubernetes-sigs/kustomize
// and the kubectl CLI can then both depend on the kustomize API.
//
// So, all code that depends on k8sdeps must go behind interfaces,
// and kustomize must be factored to choose the implementation.
//
// That problem has been reduced to three interfaces, each having
// two implementations. (1) is k8sdeps-based, (2) is kyaml-based.
//
// - ifc.Kunstructured
//
// 1) api/k8sdeps/kunstruct.UnstructAdapter
//
// This adapts structs in
// k8s.io/apimachinery/pkg/apis/meta/v1/unstructured
// to ifc.Kunstructured.
//
// 2) api/wrappy.WNode
//
// This adapts sigs.k8s.io/kustomize/kyaml/yaml.RNode
// to ifc.Unstructured.
//
// At time of writing, implementation started.
// Further reducing the size of ifc.Kunstructed
// would really reduce the work
// (e.g. drop Vars, drop ReplacementTranformer).
//
// - resmap.Merginator
//
// 1) api/internal/k8sdeps/merge.Merginator
//
// Uses k8s.io/apimachinery/pkg/util/strategicpatch,
// apimachinery/pkg/util/mergepatch, etc. to merge
// resource.Resource instances.
//
// 2) api/internal/merge.Merginator
//
// At time of writing, this is unimplemented.
//
// - ifc.Validator
//
// 1) api/k8sdeps/validator.KustValidator
//
// Uses k8s.io/apimachinery/pkg/api/validation and
// friends to validate strings.
//
// 2) api/internal/validate.FieldValidator
//
// At time of writing, this is a do-nothing
// validator as it's not critical to kustomize function.
//
// Proposed plan:
// [ ] Ship kustomize with the ability to switch from 1 to 2 via
// an --enable_kyaml flag.
// [ ] Make --enable_kyaml true by default.
// [ ] When 2 is not noticeably more buggy than 1, delete 1.
// I.e. delete k8sdeps/, transitively deleting all k8s.io/api* deps.
// This DepProvider should be left in place to retain these
// comments, but it will have only one choice.
// [ ] The way is now clear to reintegrate into kubectl.
// This should be done ASAP; the last step is cleanup.
// [ ] With only one impl of Kunstructure remaining, that interface
// and WNode can be deleted, along with this DepProvider.
// The other two interfaces could be dropped too.
//
// When the above is done, kustomize will use yaml.RNode and/or
// KRM Config Functions directly and exclusively.
// If you're reading this, plan not done.

<p><strong><code>kustomize.config.k8s.io/needs-hash</code></strong></p>
<p>Resources can be marked as needing to be processed by the internal hash transformer by including the <code>needs-hash</code> annotation. When set valid values for the annotation are <code>&quot;true&quot;</code> and <code>&quot;false&quot;</code> which respectively enable or disable hash suffixing for the resource. Omitting the annotation is equivalent to setting the value <code>&quot;false&quot;</code>.</p>
<p>If this annotation is set on a resource not supported by the hash transformer the build will fail.</p>
<p>Hashes are determined as follows:</p>
<ul>
<li>For <code>ConfigMap</code> resources, hashes are based on the values of the <code>name</code>, <code>data</code>, and <code>binaryData</code> fields.</li>
<li>For <code>Secret</code> resources, hashes are based on the values of the <code>name</code>, <code>type</code>, <code>data</code>, and <code>stringData</code> fields.</li>
<li>For any other object type, hashes are based on the entire object content (i.e. all fields).</li>
</ul>
<p>Example:</p>
<div class="highlight"><pre style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-yaml" data-lang="yaml"><span style="color:#204a87;font-weight:bold">apiVersion</span><span style="color:#000;font-weight:bold">:</span><span style="color:#f8f8f8;text-decoration:underline"> </span>v1<span style="color:#f8f8f8;text-decoration:underline">
