3. [Generate and use Self-signed Keys and Certificates with MinIO](#generate-use-self-signed-keys-certificates)
4. [Install Certificates from Third-party CAs](#install-certificates-from-third-party-cas)

## 1. Install MinIO Server

        - name: cert-secret-volume-mc
          secret:
            secretName: {{ .Values.tls.certSecret }}
            items:
              - key: {{ .Values.tls.publicCrt }}
                path: CAs/public.crt
        {{- end }}
        {{- if .Values.customCommandJob.extraVolumes }}
          {{- toYaml .Values.customCommandJob.extraVolumes | nindent 8 }}
        {{- end }}
      {{- if .Values.serviceAccount.create }}

Then install the chart, specifying that you want to use the TLS secret:

```bash
helm install --set tls.enabled=true,tls.certSecret=tls-ssl-minio minio/minio
```

### Installing certificates from third party CAs

          secretName: tls-ssl-minio
          items:
          - key: public.crt
            path: public.crt
          - key: private.key
            path: private.key
          - key: public.crt
            path: CAs/public.crt
```

Note that the `secretName` should be same as the secret name created in previous step. Then add the below section under
`spec.containers[].volumeMounts[]`

```yaml
    volumeMounts:

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 }} {{- end -}} {{/* Formats volume for MinIO TLS keys and trusted certs */}} {{- define "minio.tlsKeysVolume" -}} {{- if .Values.tls.enabled }} - name:...

{{- 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 }}
{{- end -}}

{{/*
Formats volume for MinIO TLS keys and trusted certs
*/}}

	// Check and load Root CAs.
	globalRootCAs, err = certs.GetRootCAs(globalCertsCADir.Get())
	logger.FatalIf(err, "Failed to read root CAs (%v)", err)

	// Add the global public crts as part of global root CAs
	for _, publicCrt := range globalPublicCerts {
		globalRootCAs.AddCert(publicCrt)
	}

	// Register root CAs for remote ENVs
	env.RegisterGlobalCAs(globalRootCAs)

	if err != nil {
		return nil, nil, false, err
	}
	for _, file := range files {
		// Ignore all
		// - regular files
		// - "CAs" directory
		// - any directory which starts with ".."
		if file.Mode().IsRegular() || file.Name() == "CAs" || strings.HasPrefix(file.Name(), "..") {
			continue
		}
		if file.Mode()&os.ModeSymlink == os.ModeSymlink {

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 }} {{- end -}} {{/* Formats volume for MinIO TLS keys and trusted certs */}} {{- define "minio.tlsKeysVolume" -}} {{- if .Values.tls.enabled }} - name:...

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.
