<a href=/v1.13/docs/reference/commands/istioctl/#istioctl-tag>Revision tags</a> solve this problem.
<a href=/v1.13/docs/reference/commands/istioctl/#istioctl-tag>Revision tags</a> are stable identifiers that point to revisions and can be used to avoid relabeling namespaces. Rather than relabeling the namespace, a mesh operator can simply change the tag to point to a new revision. All namespaces labeled with that tag will be updated at the same time.<h4 id=usage>Usage</h4>Consider a cluster with two revisions installed, <code>1-9-5</code> and <code>1-10-0</code>. The cluster operator creates a revision tag <code>prod-stable</code>,
pointed at the older, stable <code>1-9-5</code> version, and a revision tag <code>prod-canary</code> pointed at the newer <code>1-10-0</code> revision. That
state could be reached via these commands:<pre><code class=language-bash data-expandlinks=true data-repo=istio>$ helm template istiod istio/istiod -s templates/revision-tags.yaml --set revisionTags={prod-stable} --set revision=1-9-5 -n istio-system | kubectl apply -f -
$ helm template istiod istio/istiod -s templates/revision-tags.yaml --set revisionTags={prod-canary} --set revision=1-10-0 -n istio-system | kubectl apply -f -
</code></pre><div><aside class="callout warning"><div class=type><svg class="large-icon"><use xlink:href="/v1.13/img/icons.svg#callout-warning"/></svg></div><div class=content>These commands create new <code>MutatingWebhookConfiguration</code> resources in your cluster, however, they are not owned by any Helm chart due to <code>kubectl</code> manually applying the templates. See the instructions
below to uninstall revision tags.</div></aside></div><p>The resulting mapping between revisions, tags, and namespaces is as shown below:</p><figure style=width:70%><div class=wrapper-with-intrinsic-ratio style=padding-bottom:55.51282051282052%><a data-skipendnotes=true href=/v1.13/docs/setup/upgrade/canary/tags.png title="Two namespaces pointed to prod-stable and one pointed to prod-canary"><img class=element-to-stretch src=/v1.13/docs/setup/upgrade/canary/tags.png alt="Two namespaces pointed to prod-stable and one pointed to prod-canary"></a></div><figcaption>Two namespaces pointed to prod-stable and one pointed to prod-canary</figcaption></figure><p>The cluster operator can view this mapping in addition to tagged namespaces through the <code>istioctl tag list</code> command:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ istioctl tag list
TAG REVISION NAMESPACES
prod-canary 1-10-0 ...
prod-stable 1-9-5 ...
</code></pre><p>After the cluster operator is satisfied with the stability of the control plane tagged with <code>prod-canary</code>, namespaces labeled
<code>istio.io/rev=prod-stable</code> can be updated with one action by modifying the <code>prod-stable</code> revision tag to point to the newer
<code>1-10-0</code> revision.</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ helm template istiod istio/istiod -s templates/revision-tags.yaml --set revisionTags={prod-stable} --set revision=1-10-0 -n istio-system | kubectl apply -f -
</code></pre><p>Now, the situation is as below:</p><figure style=width:70%><div class=wrapper-with-intrinsic-ratio style=padding-bottom:55.51282051282052%><a data-skipendnotes=true href=/v1.13/docs/setup/upgrade/canary/tags-updated.png title="Namespace labels unchanged but now all namespaces pointed to 1-10-0"><img class=element-to-stretch src=/v1.13/docs/setup/upgrade/canary/tags-updated.png alt="Namespace labels unchanged but now all namespaces pointed to 1-10-0"></a></div><figcaption>Namespace labels unchanged but now all namespaces pointed to 1-10-0</figcaption></figure><p>Restarting injected workloads in the namespaces marked <code>prod-stable</code> will now result in those workloads using the <code>1-10-0</code>
control plane. Notice that no namespace relabeling was required to migrate workloads to the new revision.</p><h4 id=default-tag>Default tag</h4><p>The revision pointed to by the tag <code>default</code> is considered the <strong><em>default revision</em></strong> and has additional semantic meaning. The default
revision performs the following functions:</p><ul><li>Injects sidecars for the <code>istio-injection=enabled</code> namespace selector, the <code>sidecar.istio.io/inject=true</code> object
selector, and the <code>istio.io/rev=default</code> selectors</li><li>Validates Istio resources</li><li>Steals the leader lock from non-default revisions and performs singleton mesh responsibilities (such as updating resource statuses)</li></ul><p>To make a revision <code>1-10-0</code> the default, run:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ helm template istiod istio/istiod -s templates/revision-tags.yaml --set revisionTags={default} --set revision=1-10-0 -n istio-system | kubectl apply -f -
</code></pre>When using the <code>default</code> tag alongside an existing non-revisioned Istio installation it is recommended to remove the old
<code>MutatingWebhookConfiguration</code> (typically called <code>istio-sidecar-injector</code>) to avoid having both the older and newer control
planes attempt injection.<h3 id=in-place-upgrade>In place upgrade</h3><p>You can perform an in place upgrade of Istio in your cluster using the Helm
