Variáveis de ambiente podem ser úteis para lidar com **configurações** do aplicativo, como parte da **instalação** do Python, etc.

## Criar e Usar Variáveis de Ambiente

Você pode **criar** e usar variáveis de ambiente no **shell (terminal)**, sem precisar do Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```sh
firewall-cmd --reload
```

### iptables

For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow
access to port 9000

```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```

Bijvoorbeeld “**Python 3.6+**” betekent dat het compatibel is met Python 3.6 of hoger (inclusief 3.7, 3.8, 3.9, 3.10, etc). En “**Python 3.9+**” betekent dat het compatibel is met Python 3.9 of hoger (inclusief 3.10, etc).

		NetworkNamespace:         "",

}

func realDependenciesInpod() *dep.RealDependencies {
	return &dep.RealDependencies{
		// We are running the host FS, but the pod network -- setup rules differently (locking, etc)
		HostFilesystemPodNetwork: true,
		NetworkNamespace:         "",
	}
}

// RemovePodFromMesh is called when a pod needs to be removed from the mesh

MinIO follows strict **read-after-write** and **list-after-write** consistency model for all i/o operations both in distributed and standalone modes. This consistency model is only guaranteed if you use disk filesystems such as xfs, zfs or btrfs etc.. for distributed setup.

**In our tests we also found ext4 does not honor POSIX O_DIRECT/Fdatasync semantics, ext4 trades performance for consistency guarantees. Please avoid ext4 in your setup.**
