<p>I am getting the following error on installing a custom docker image as a revision. I am not able to figure out the reason. So far I have tried adding secrets with the password and it didn't work</p>
<pre><code>helm upgrade --install airflow apache-airflow/airflow -n airflow -f values.yaml --debug
history.go:56: [debug] getting history for release airflow
upgrade.go:144: [debug] preparing upgrade for airflow
Error: UPGRADE FAILED: execution error at (airflow/charts/postgresql/templates/secrets.yaml:20:15): 
PASSWORDS ERROR: The secret &quot;airflow-postgresql&quot; does not contain the key &quot;password&quot;
</code></pre>

<p>Try this:</p>
<pre><code>kubectl create secret generic airflow-postgresql -n airflow --from-literal=password='postgres' --dry-run=client -o yaml | kubectl apply -f -
</code></pre>
<p>I think the error is due to the helm create the airflow-postgresql's secrets using &quot;postgres-password&quot; as the key while the helm update expects &quot;password&quot; as the key.</p>
<p>Or:</p>

<p>Airflow Helm Chart 1.8.0 (2023-02-06)
Significant Changes
bitnami/postgresql subchart updated to 12.1.9 (#29071)
The version of postgresql installed is still version 11.</p>
<p>If you are upgrading an existing helm release with the built-in postgres database, you will either need to delete your release and reinstall fresh, or manually delete these 2 objects:</p>
<pre><code>kubectl delete secret {RELEASE_NAME}-postgresql
kubectl delete statefulset {RELEASE_NAME}-postgresql
</code></pre>
<p>As a reminder, it is recommended to set up an external database in production.</p>
<p>This version of the chart uses different variable names for setting usernames and passwords in the postgres database.</p>
<p>postgresql.auth.enablePostgresUser is used to determine if the “postgres” admin account will be created.</p>
<p>postgresql.auth.postgresPassword sets the password for the “postgres” user.</p>
<p>postgresql.auth.username and postrgesql.auth.password are used to set credentials for a non-admin account if desired.</p>
<p>postgresql.postgresqlUsername and postgresql.postresqlPassword, which were used in the previous version of the chart, are no longer used.</p>
<p>Users will need to make those changes in their values files if they are changing the Postgres configuration.</p>
<p>Previously the subchart version was 10.5.3.</p>
