Contents</h1><p>Fleet will create bundles from a git repository. This happens either explicitly by specifying paths, or when a <code>fleet.yaml</code> is found.</p><p>Each bundle is created from paths in a GitRepo and modified further by reading the discovered <code>fleet.yaml</code> file.
Bundle lifecycles are tracked between releases by the helm releaseName field added to each bundle. If the releaseName is not
specified within fleet.yaml it is generated from <code>GitRepo.name + path</code>. Long names are truncated and a <code>-&lt;hash&gt;</code> prefix is added.</p><p><strong>The git repository has no explicitly required structure.</strong> It is important
to realize the scanned resources will be saved as a resource in Kubernetes so
you want to make sure the directories you are scanning in git do not contain
arbitrarily large resources. Right now there is a limitation that the resources
deployed must <strong>gzip to less than 1MB</strong>.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="proper-namespace">Proper Namespace<a href="#proper-namespace" class="hash-link" aria-label="Direct link to Proper Namespace" title="Direct link to Proper Namespace"></a></h2><p>Git repos are added to the Fleet manager using the <code>GitRepo</code> custom resource type.

An example of a special case might be including the local cluster in the <code>GitRepo</code> payload for config maps and secrets (no active deployments or payloads).</p><div class="theme-admonition theme-admonition-warning alert alert--danger admonition_LlT9"><div class="admonitionHeading_tbUL"><span class="admonitionIcon_kALy"><svg viewBox="0 0 12 16"><path fill-rule="evenodd" d="M5.05.31c.81 2.17.41 3.38-.52 4.31C3.55 5.67 1.98 6.45.9 7.98c-1.45 2.05-1.7 6.53 3.53 7.7-2.2-1.16-2.67-4.52-.3-6.61-.61 2.03.53 3.33 1.94 2.86 1.39-.47 2.3.53 2.27 1.67-.02.78-.31 1.44-1.13 1.81 3.42-.59 4.78-3.42 4.78-5.56 0-2.84-2.53-3.22-1.25-5.61-1.52.13-2.03 1.13-1.89 2.75.09 1.08-1.02 1.8-1.86 1.33-.67-.41-.66-1.19-.06-1.78C8.18 5.31 8.68 2.45 5.05.32L5.03.3l.02.01z"></path></svg></span>Local Cluster</div><div class="admonitionContent_S0QG"><p>While it&#x27;s possible to move clusters out of either workspace, we recommend that you keep the local cluster in <code>fleet-local</code>.</p></div></div><p>If you are using Fleet in a <a href="/0.6/concepts">single cluster</a> style, the namespace will always be <strong>fleet-local</strong>.

determines how the resources are customized per target.</p><p>All clusters and cluster groups in the same namespace as the <code>GitRepo</code> will be evaluated against all targets of that
<code>GitRepo</code>. The targets list is evaluated one by one and if there is a match the resource will be deployed to the cluster.
If no match is made against the target list on the <code>GitRepo</code> then the resources will not be deployed to that cluster.
Once a target cluster is matched the <code>fleet.yaml</code> from the git repository is then consulted for customizations. The
<code>targetCustomizations</code> in the <code>fleet.yaml</code> will be evaluated one by one and the first match will define how the
resource is to be configured. If no match is made the resources will be deployed with no additional customizations.</p><p>There are three approaches to matching clusters for both <code>GitRepo</code> <code>targets</code> and <code>fleet.yaml</code> <code>targetCustomizations</code>.
One can use cluster selectors, cluster group selectors, or an explicit cluster group name. All criteria is additive so
the final match is evaluated as &quot;clusterSelector &amp;&amp; clusterGroupSelector &amp;&amp; clusterGroup&quot;. If any of the three have the
default value it is dropped from the criteria. The default value is either null or &quot;&quot;. It is important to realize
that the value <code>{}</code> for a selector means &quot;match everything.&quot;</p><div class="language-yaml codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#bfc7d5;--prism-background-color:#292d3e"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-yaml codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#bfc7d5"><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># Match everything</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token key atrule">clusterSelector</span><span class="token punctuation" style="color:rgb(199, 146, 234)">:</span><span class="token plain"> </span><span class="token punctuation" style="color:rgb(199, 146, 234)">{</span><span class="token punctuation" style="color:rgb(199, 146, 234)">}</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># Selector ignored</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token key atrule">clusterSelector</span><span class="token punctuation" style="color:rgb(199, 146, 234)">:</span><span class="token plain"> </span><span class="token null important">null</span><br></span></code></pre><div class="buttonGroup__atx"><button type="button" aria-label="Copy code to clipboard" title="Copy" class="clean-btn"><span class="copyButtonIcons_eSgA" aria-hidden="true"><svg class="copyButtonIcon_y97N" viewBox="0 0 24 24"><path d="M19,21H8V7H19M19,5H8A2,2 0 0,0 6,7V21A2,2 0 0,0 8,23H19A2,2 0 0,0 21,21V7A2,2 0 0,0 19,5M16,1H4A2,2 0 0,0 2,3V17H4V3H16V1Z"></path></svg><svg class="copyButtonSuccessIcon_LjdS" viewBox="0 0 24 24"><path d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div><h2 class="anchor anchorWithStickyNavbar_LWe7" id="raw-yaml-resource-customization">Raw YAML Resource Customization<a href="#raw-yaml-resource-customization" class="hash-link" aria-label="Direct link to Raw YAML Resource Customization" title="Direct link to Raw YAML Resource Customization"></a></h2><p>When using Kustomize or Helm the <code>kustomization.yaml</code> or the <code>helm.values</code> will control how the resource are
customized per target cluster. If you are using raw YAML then the following simple mechanism is built-in and can
be used. The <code>overlays/</code> folder in the git repo is treated specially as folder containing folders that
can be selected to overlay on top per target cluster. The resource overlay content
uses a file name based approach. This is different from kustomize which uses a resource based approach. In kustomize
the resource Group, Kind, Version, Name, and Namespace identify resources and are then merged or patched. For Fleet
the overlay resources will override or patch content with a matching file name.</p><div class="language-shell codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#bfc7d5;--prism-background-color:#292d3e"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-shell codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#bfc7d5"><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># Base files</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">deployment.yaml</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">svc.yaml</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain" style="display:inline-block"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># Overlay files</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain" style="display:inline-block"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># The following file will be added</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">overlays/custom/configmap.yaml</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># The following file will replace svc.yaml</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">overlays/custom/svc.yaml</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"></span><span class="token comment" style="color:rgb(105, 112, 152);font-style:italic"># The following file will patch deployment.yaml</span><span class="token plain"></span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">overlays/custom/deployment_patch.yaml</span><br></span></code></pre><div class="buttonGroup__atx"><button type="button" aria-label="Copy code to clipboard" title="Copy" class="clean-btn"><span class="copyButtonIcons_eSgA" aria-hidden="true"><svg class="copyButtonIcon_y97N" viewBox="0 0 24 24"><path d="M19,21H8V7H19M19,5H8A2,2 0 0,0 6,7V21A2,2 0 0,0 8,23H19A2,2 0 0,0 21,21V7A2,2 0 0,0 19,5M16,1H4A2,2 0 0,0 2,3V17H4V3H16V1Z"></path></svg><svg class="copyButtonSuccessIcon_LjdS" viewBox="0 0 24 24"><path d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div><p>A file named <code>foo</code> will replace a file called <code>foo</code> from the base resources or a previous overlay. In order to patch
the contents of a file the convention of adding <code>_patch.</code> (notice the trailing period) to the filename is used. The string <code>_patch.</code>
will be replaced with <code>.</code> from the file name and that will be used as the target. For example <code>deployment_patch.yaml</code>
will target <code>deployment.yaml</code>. The patch will be applied using JSON Merge, Strategic Merge Patch, or JSON Patch.
Which strategy is used is based on the file content. Even though JSON strategies are used, the files can be written
using YAML syntax.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="cluster-and-bundle-state">Cluster and Bundle State<a href="#cluster-and-bundle-state" class="hash-link" aria-label="Direct link to Cluster and Bundle State" title="Direct link to Cluster and Bundle State"></a></h2><p>See <a href="/0.6/cluster-bundles-state">Cluster and Bundle state</a>.</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/rancher/fleet-docs/edit/main/versioned_docs/version-0.6/gitrepo-content.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_Z9Sw" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div><div class="col lastUpdated_vwxv"><span class="theme-last-updated">Last updated<!-- --> on <b><time datetime="2023-05-15T14:46:52.000Z">May 15, 2023</time></b></span></div></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages navigation"><a class="pagination-nav__link pagination-nav__link--prev" href="/0.6/ref-bundle-stages"><div class="pagination-nav__sublabel">Previous</div><div class="pagination-nav__label">Bundle Lifecycle</div></a><a class="pagination-nav__link pagination-nav__link--next" href="/0.6/namespaces"><div class="pagination-nav__sublabel">Next</div><div class="pagination-nav__label">Namespaces</div></a></nav></div></div><div class="col col--3"><div class="tableOfContents_bqdL thin-scrollbar theme-doc-toc-desktop"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#proper-namespace" class="table-of-contents__link toc-highlight">Proper Namespace</a></li><li><a href="#how-repos-are-scanned" class="table-of-contents__link toc-highlight">How repos are scanned</a></li><li><a href="#fleetyaml" class="table-of-contents__link toc-highlight"><code>fleet.yaml</code></a></li><li><a href="#per-cluster-customization" class="table-of-contents__link toc-highlight">Per Cluster Customization</a></li><li><a href="#raw-yaml-resource-customization" class="table-of-contents__link toc-highlight">Raw YAML Resource Customization</a></li><li><a href="#cluster-and-bundle-state" class="table-of-contents__link toc-highlight">Cluster and Bundle State</a></li></ul></div></div></div></div></main></div></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="footer__bottom text--center"><div class="footer__copyright">Copyright © 2023 SUSE Rancher.
