## Deployment Recommendations

### Allow port access for Firewalls

By default MinIO uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.

### ufw

For hosts with ufw enabled (Debian based distros), you can use `ufw` command to allow traffic to specific ports. Use below command to allow access to port 9000

```sh
ufw allow 9000

	// 1. Create a policy
	policy1 := "deny-svc"
	policy2 := "allow-svc"
	policyBytes := []byte(`{
 "Version": "2012-10-17",
 "Statement": [
  {
   "Effect": "Deny",
   "Action": [
    "admin:CreateServiceAccount"
   ]
  }
 ]
}`)

	newPolicyBytes := []byte(`{
 "Version": "2012-10-17",
 "Statement": [
  {
   "Effect": "Allow",
   "Action": [
    "s3:ListBucket"
   ],

        server site1-minio4:9000;
    }

    server {
        listen       9001;
        listen  [::]:9001;
        server_name  localhost;

        # To allow special characters in headers
        ignore_invalid_headers off;
        # Allow any size file to be uploaded.
        # Set to a value such as 1000m; to restrict file size to a specific value
        client_max_body_size 0;
        # To disable buffering
