Copy the existing private key and public certificate to the `certs` directory. The default certs directory is:

* **Linux:** `${HOME}/.minio/certs`
* **Windows:** `%%USERPROFILE%%\.minio\certs`

**Note:**

* Location of custom certs directory can be specified using `--certs-dir` command line option.
* Inside the `certs` directory, the private key must by named `private.key` and the public key must be named `public.crt`.

Here the name of `volumeMount` should match the name of `volume` created previously. Also `mountPath` must be set to the path of
the MinIO server's config sub-directory that is used to store certificates. By default, the location is
`/<user-running-minio>/.minio/certs`.

*Tip*: In a standard Kubernetes configuration, this will be `/root/.minio/certs`. Kubernetes will mount the secrets volume read-only,

{{/*
Formats volumeMount for MinIO TLS keys and trusted certs
*/}}
{{- define "minio.tlsKeysVolumeMount" -}}
{{- if .Values.tls.enabled }}
- name: cert-secret-volume
  mountPath: {{ .Values.certsPath }}
{{- end }}
{{- if or .Values.tls.enabled (ne .Values.trustedCertsSecret "") }}
{{- $casPath := printf "%s/CAs" .Values.certsPath | clean }}
- name: trusted-cert-secret-volume
  mountPath: {{ $casPath }}
{{- end }}

```

If TLS is not enabled, you would need only the third party CA:

```
kubectl -n minio create secret generic minio-trusted-certs --from-file=keycloak.crt
```

Following is a sample directory structure for MinIO server with TLS certificates.

```sh
$ mc tree --files ~/.minio
/home/user1/.minio
└─ certs
   ├─ CAs
   ├─ private.key
   └─ public.crt
```

You can provide a custom certs directory using `--certs-dir` command line option.

#### Credentials

On MinIO admin credentials or root credentials are only allowed to be changed using ENVs namely `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.
