|
<p>After security review, a field used in secret
|
|
generation (see below) was removed from the
|
|
definition of a kustomization file with no
|
|
mechanism to convert it to a new form. Also, the
|
|
set of files accessible from a kustomization file
|
|
has been further constrained.</p>
|
|
<p>Per the <a href="/kustomize/faq/versioningpolicy">versioning policy</a>,
|
|
backward incompatible changes trigger an increment
|
|
of the major version number, hence we go
|
|
from 1.0.11 to 2.0.0. We’re taking this major
|
|
version increment opportunity to remove some
|
|
already deprecated fields, and the code paths
|
|
associated with them.</p>
|
|
<h2 id="backward-incompatible-changes">Backward Incompatible Changes</h2>
|
|
<h3 id="kustomization-path-constraints">Kustomization Path Constraints</h3>
|
|
<p>A kustomization file can specify paths to other
|
|
files, including resources, patches, configmap
|
|
generation data, secret generation data and
|
|
bases. In the case of a base, the path can be a
|
|
git URL instead.</p>
|
|
<p>In 1.x, these paths had to be relative to the
|
|
current kustomization directory (the location of
|
|
the kustomization file used in the <code>build</code>
|
|
command).</p>
|
|
<p>In 2.0, bases can continue to specify, via
|
|
relative paths, kustomizations outside the current
|
|
kustomization directory. But non-base paths are
|
|
constrained to terminate in or below the current
|
|
kustomization directory. Further, bases specified
|
|
via a git URL may not reference files outside of
|
|
the directory used to clone the repository.</p>
|
|
<h3 id="kustomization-field-removals">Kustomization Field Removals</h3>
|
|
<h4 id="patches">patches</h4>
|
|
<p><code>patches</code> was deprecated and replaced by
|
|
<code>patchesStrategicMerge</code> when <code>patchesJson6902</code> was
|
|
introduced. In Kustomize 2.0.0, <code>patches</code> is
|
|
removed. Please use <code>patchesStrategicMerge</code>
|
|
instead.</p>
|
|
<h4 id="imagetags">imageTags</h4>
|
|
<p><code>imageTags</code> is replaced by <code>images</code> since <code>images</code>
|
|
can provide more features to change image names,
|
|
registries, tags and digests.</p>
|
|
<h4 id="secretgeneratorcommands">secretGenerator/commands</h4>
|
|
<p><code>commands</code> is removed from SecretGenerator due to
|
|
a <a href="https://docs.google.com/document/d/1FYgLVdq-siB_Cef9yuQBmit0PbrE8lsyTBdGI2eA2y8/edit">security concern</a>. One can use <code>files</code> or
|
|
<code>literals</code>, similar to ConfigMapGenerator, to
|
|
generate a secret.</p>
|
|
<pre><code>secretGenerator:
|
|
- name: app-tls
|
|
files:
|
|
- secret/tls.cert
|
|
- secret/tls.key
|
|
type: "kubernetes.io/tls"
|
|
</code></pre><h2 id="compatible-changes-new-features">Compatible Changes (New Features)</h2>
|
|
<p>As this release is triggered by a security change,
|
|
there are no major new features to announce. A few
|
|
things that are worth mentioning in this release
|
|
are:</p>
|
|
<ul>
|
|
<li>
|
|
<p>More than <em>40</em> issues closed since 1.0.11
|
|
release (including many extensions to
|
|
transformation rules).</p>
|
|
</li>
|
|
<li>
|
|
<p>Users can run <code>kustomize edit fix</code> to migrate a
|
|
kustomization file working with previous
|
|
versions to one working with 2.0.0. For example,
|
|
a kustomization.yaml with following content</p>
|
|
<pre><code>patches:
|
|
- deployment-patch.yaml
|
|
imageTags:
|
|
- name: postgres
|
|
newTag: v1
|
|
</code></pre><p>will be converted to</p>
|
|
<pre><code>apiVersion: kustomize.config.k8s.io/v1beta1
|
|
kind: Kustomization
|
|
patchesStrategicMerge:
|
|
- deployment-patch.yaml
|
|
images:
|
|
- name: postgres
|
|
newTag: v1
|
|
</code></pre></li>
|
|
<li>
|
|
<p>Kustomization filename</p>
|
|
<p>In previous versions, the name of a
|
|
kustomization file had to be
|
|
<code>kustomization.yaml</code>.
|
|
Kustomize allows <code>kustomization.yaml</code>,
|
|
<code>kustomization.yml</code> and
|
|
<code>Kustomization</code>. In a directory, only one of
|
|
those filenames is allowed. If there are more
|
|
than one found, Kustomize will exit with an
|
|
error. Please select the best filename for your
|
|
use cases.</p>
|
|
</li>
|
|
<li>
|
|
<p>Cancelled plans to deprecate applying prefix/suffix to namespace.
|
|
The deprecation warning</p>
|
|
<pre><code>Adding nameprefix and namesuffix to Namespace resource will be deprecated in next release.
|
|
</code></pre><p>was removed.</p>
