# Store release information in an SQL database
|
|
|
|
You may be willing to store release information in an SQL database - in
|
|
particular, if your releases weigh more than 1MB and therefore [can't be stored in ConfigMaps or Secrets](https://github.com/helm/helm/issues/1413).
|
|
|
|
We recommend using [PostgreSQL](https://www.postgresql.org/).
|
|
|
|
This document describes how to deploy `postgres` atop Kubernetes. This being
|
|
said, using an out-of-cluster (managed or not) PostreSQL instance is totally
|
|
possible as well.
|
|
|
|
Here's a Kubernetes manifest you can apply to get a minimal PostreSQL pod
|
|
running on your Kubernetes cluster. **Don't forget to change the credentials
|
|
and, optionally, enable TLS in production deployments**.
|
|
|
|
```yaml
|

Once postgres is deployed, you'll need to install Tiller using `helm init`, with
|
|
a few custom CLI flags:
|
|
|
|
```shell
|
|
helm init \
|
|
--override \
|
|
'spec.template.spec.containers[0].args'='{--storage=sql,--sql-dialect=postgres,--sql-connection-string=postgresql://tiller-postgres:5432/helm?user=helm&password=changemeforgodssake&sslmode=disable}'
|
|
```
