<p><code>rsync://username@server/path/to/folder</code></p>
<p>This deploys via SSH and rsync to a remote server. This is the recommended
way to deploy if the system supports it as it is a very fast and reliable
way. It uses the system's SSH config so for authentication just configure
SSH as you would normally do. The <code>username</code> part is optional and defaults
to the current user that is signed into the machine or whatever is picked up
as default from the <code>.ssh/config</code>.</p>

</pre></div>
<h2 id="credentials">Credentials</h2><p>The <code>rsync</code> deploy method supports both username and password parameter
though it's recommended to use <code>.ssh/config</code> and an SSH agent to secure
the deployment. The <code>--password</code> parameter is not supported! Instead you
need to use <code>--key-file</code> (<code>LEKTOR_DEPLOY_KEY_FILE</code>) or <code>--key</code>
(<code>LEKTOR_DEPLOY_KEY</code>). The <code>--key-file</code> is the path to an OpenSSH private
key.</p>
<p>If you are using <code>--key</code> you can directly copy paste the contents of a key
into a string. This is useful if you want to use it as an environment
variable. The format for the string is <code>KEY_TYPE:BASE64</code> where <code>KEY_TYPE</code>
is the type of the key (<code>RSA</code>, <code>EC</code>, etc.) and <code>BASE64</code> is the base64 encoded
private key without newlines or whitespace. To find out which type your
key is look at the first line of the key marker. For instance <code>BEGIN EC
PRIVATE KEY</code> indicates an <code>EC</code> key. If no key type is defined <code>RSA</code> is
assumed.</p>
<h2 id="deletion-support">Deletion Support</h2><div class="admonition admonition-info"><p>New in version 3.2.</p></div><p>To keep two directories truly in sync when deploying with <code>rsync</code>,
it's necessary to explicitly tell <code>rsync</code> to remove files or directories
on target that don't exist on source anymore. This can be done using the
<code>?delete</code> URL parameter:</p>
2022-05-03 00:53:59 +02:00
<div class="hll"><pre><span></span><span class="k">[servers.production]</span><span class="w"></span>
2022-02-20 15:15:38 +01:00
<span class="na">target</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">rsync://server/path/to/folder?delete</span><span class="w"></span>
</pre></div>
<p>If the parameter is provided Lektor will issue a <code>rsync --delete-delay</code>,
which performs deletions after all other transfers ended, and only in case
there were no failures.</p>
<div class="admonition admonition-warning"><p>Note that the <code>?delete</code> option will remove <strong>any file or directory</strong>
on target that does not exist on source. This means that if you have files
in the target tree that are not managed by lektor, they will get removed.</p></div><h2 id="exclusion-support">Exclusion Support</h2><p>You can exclude items from being synced by using one or more <code>exclude</code>
parameters. This is also useful in combination with <code>delete</code> to prevent
removal of files in the target tree that are not managed by lektor:</p>
