The workaround is to use `configOverrides` in your `values.yaml`. The chart's `_helpers.tpl` appends `configOverrides` **after** the generated config blocks and passes them through `tpl`, so raw Python ends up in the file as-is [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/helm/superset/templates/_helpers.tpl#L121-L127). Since Python uses last-assignment-wins, you can simply redeclare the affected variables: ```yaml configOverrides: redis_backends: | RESULTS_BACKEND = RedisCache( host=env('REDIS_HOST'), password=env('REDIS_PASSWORD'), port=env('REDIS_PORT'), key_prefix='superset_results', ) GLOBAL_ASYNC_QUERIES_CACHE_BACKEND = { "CACHE_TYPE": "RedisCache", "CACHE_REDIS_HOST": env("REDIS_HOST"), "CACHE_REDIS_PORT": int(env("REDIS_PORT", "6379")), "CACHE_REDIS_PASSWORD": env("REDIS_PASSWORD", ""), "CACHE_REDIS_DB": 1, "CACHE_KEY_PREFIX": "qc-", } GLOBAL_ASYNC_QUERIES_RESULTS_BACKEND = { "backend": "redis", "host": env("REDIS_HOST"), "port": int(env("REDIS_PORT", "6379")), "password": env("REDIS_PASSWORD", ""), "db": 1, } ``` This keeps the secret out of the rendered config — `env('REDIS_PASSWORD')` is emitted as Python source and evaluated at pod startup. The `env()` helper is available because it's [defined earlier](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/helm/superset/templates/_helpers.tpl#L69-L70) in the same generated file. One broader note: the official Helm chart is deprecated in favor of the [Superset Kubernetes Operator](https://apache.github.io/superset-kubernetes-operator/), which has a more structured secrets/config model and a [migration guide](https://apache.github.io/superset-kubernetes-operator/user-guide/migration/) if you're considering longer-term options [[2]](https://app.dosu.dev/a28d3c7e-a9d3-459e-9fb6-3a6f9ff4f357/documents/93724521-b01c-44ef-ac7c-dd1b755a5179). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Docs are dead.
