Hello Arthur,
> Error: Failed to render chart: exit status 1: Error: values don't meet the
specifications of the schema(s) in the following chart(s):
airflow:
data.resultBackendConnection: pass is required
data.resultBackendConnection: sslmode is required
data.resultBackendConnection: Additional property password is not allowed
Error: plugin "diff" exited with error
We build the Url from the
[values](https://github.com/apache/airflow/blob/main/chart/templates/secrets/result-backend-connection-secret.yaml#L46-L46),
so you should provide it as the following to create the secret:
```yaml
data:
resultBackendConnection:
protocol: redis
host: my.host.io
port: 6379
db: airflow
user: airflow_user
pass: airflow_pass
sslmode: disable
```
This creates a new secret:
```yaml
kind: Secret
apiVersion: v1
metadata:
name: release-name-airflow-result-backend
labels:
tier: airflow
release: release-name
chart: airflow
heritage: Helm
type: Opaque
data:
connection:
"ZGIrcmVkaXM6Ly9haXJmbG93X3VzZXI6YWlyZmxvd19wYXNzQG15Lmhvc3QuaW86NjM3OS9haXJmbG93"
```
And here is the raw connection value
```bash
$ echo
ZGIrcmVkaXM6Ly9haXJmbG93X3VzZXI6YWlyZmxvd19wYXNzQG15Lmhvc3QuaW86NjM3OS9haXJmbG93
| base64 -d
db+redis://airflow_user:[email protected]:6379/airflow
```
And if you prefer to avoid providing the password in the values or creating
the secret by helm, you can create the secret with the same structure and
provide its name to `.Values.data.resultBackendSecretName` which is the
recommended way.
> Although when I am doing so, I have error in my DagProcessor:
Liveness probe failed: You have configured a result_backend of
redis://my.host.io:6379/1, it is highly recommended to use an alternative
result_backend (i.e. a database).
No alive jobs found.
I think it's a problem in the provided url where the schema should be
`db+redis` instead of `redis`.
PS: if you create the secret and provide its name to
`.Values.data.resultBackendSecretName` or if you fill all the fields of
`.Values.data.resultBackendConnection` as I did in my example, you don't need
to provide the config `config.celery.config` where the connection will [be
added](https://github.com/apache/airflow/blob/main/chart/templates/_helpers.yaml#L86-L92)
to Airflow by the chart.
Can you please test the url format I suggested and check if you still have
the same problem with the liveness probe
