<p>Im attempting to incorporate git-sync sidecar container into my Airflow deployment yaml so my private Github repo gets synced to my Airflow Kubernetes env every time I make a change in the repo.</p>
<p>So far, it successfully creates a git-sync container along with our scheduler, worker, and web server pods, each in their respective pod (ex: scheduler pod contains a scheduler container and gitsync container).
 </p>
<p>I looked at the git-sync container logs and it looks like it successfully connects with my private repo (using a personal access token) and prints success logs every time I make a change to my repo.</p>

<p><strong>However, despite their being no error logs in my git-sync container logs, I could not find any of the files in the destination directory where my repo is supposed to be synced into (/opt/airflow/dags). Therefore, no DAGs are appearing in the Airflow UI</strong></p>
<p>This is our scheduler containers/volumes yaml definition for reference. We have something similar for workers and webserver</p>

<p>What can be the issue? I couldn't find much documentation that could help me further investigate. Any help and guidance would be greatly appreciated!</p>

<p>Looks like my issue was that my worker, scheduler, and web server container had different dag volume mounts from the ones I defined for my git-sync container.</p>
<p>This is what I had:</p>
<pre><code>containers:
        - name: airflow-scheduler
          image: &lt;redacted&gt;
          imagePullPolicy: IfNotPresent
          envFrom:
            - configMapRef:
                name: &quot;AIRFLOW_SERVICE_NAME-env&quot;
          env:            
            &lt;redacted&gt;
          resources: 
            requests:
              memory: RESOURCE_MEMORY
              cpu: RESOURCE_CPU
          volumeMounts:
            - name: scripts
              mountPath: /home/airflow/scripts
            - name: dags-data
              mountPath: /opt/airflow/dags
              subPath: dags
            - name: dags-data
              mountPath: /opt/airflow/plugins
              subPath: plugins
            - name: variables-pools
              mountPath: /home/airflow/variables-pools/
            - name: airflow-log-config
              mountPath: /opt/airflow/config
</code></pre>
<p>And the following edits made it work. I removed the dag subpath and plugins volume mount:</p>
<pre><code>containers:
        - name: airflow-scheduler
          image: &lt;redacted&gt;
          imagePullPolicy: IfNotPresent
          envFrom:
            - configMapRef:
                name: &quot;AIRFLOW_SERVICE_NAME-env&quot;
          env:            
            &lt;redacted&gt;
          resources: 
            requests:
              memory: RESOURCE_MEMORY
              cpu: RESOURCE_CPU
          volumeMounts:
            - name: scripts
              mountPath: /home/airflow/scripts
            - name: dags-data
              mountPath: /opt/airflow/dags
            - name: variables-pools
              mountPath: /home/airflow/variables-pools/
            - name: airflow-log-config
              mountPath: /opt/airflow/config
</code></pre>
