on nodes where the Rancher server will be installed with Helm on an RKE cluster or with Docker.

One option is to refer to the <a href="https://docs.docker.com/install/" target="_blank" rel="noopener noreferrer">official Docker documentation</a> about how to install Docker on Linux. The steps will vary based on the Linux distribution.</p><p>Another option is to use one of Rancher's Docker installation scripts, which are available for most recent versions of Docker. Rancher has installation scripts for every version of upstream Docker that Kubernetes supports.</p><p>For example, this command could be used to install on one of the main Linux distributions, such as SUSE Linux Enterprise or Ubuntu:</p><div class="language-bash codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#bfc7d5;--prism-background-color:#292d3e"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-bash codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#bfc7d5"><span class="token function" style="color:rgb(130, 170, 255)">curl</span><span class="token plain"> https://releases.rancher.com/install-docker/</span><span class="token operator" style="color:rgb(137, 221, 255)"><</span><span class="token plain">version-number</span><span class="token operator" style="color:rgb(137, 221, 255)">></span><span class="token plain">.sh </span><span class="token operator" style="color:rgb(137, 221, 255)">|</span><span class="token plain"> </span><span class="token function" style="color:rgb(130, 170, 255)">sh</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 viewBox="0 0 24 24" class="copyButtonIcon_y97N"><path fill="currentColor" 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 viewBox="0 0 24 24" class="copyButtonSuccessIcon_LjdS"><path fill="currentColor" d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div><p>Consult the <a href="https://www.suse.com/suse-rancher/support-matrix" target="_blank" rel="noopener noreferrer">Rancher support matrix</a> to match a validated Docker version with your operating system and version of Rancher.
