	Add an SSH Key for the `core` user from the local `ssh-key.pub` file.	Adicione uma chave SSH para o usuário `core`.
	Add a systemd service (`failure.service`) that fails on boot.	Adiciona um serviço do systemd (`failure.service`) que falha no boot.
	Add a running container via a Podman https://docs.podman.io/en/latest/markdown/podman-systemd.unit.5.html[quadlet systemd.unit container file].
	This `etcd-member.container` will then be associated with a `etcd-member.service` on the running system.
	`etcd-member.service` will launch and manage the lifecycle of the container using `podman`.
	Writing the Butane config and converting to Ignition	Escrevendo a configuração Fedora CoreOS e convertendo para Ignition
	Similarly to what we did in the second provisioning scenario, we will write the following Butane config in a file called `containers.bu`:	Similarmente com o que fizemos no segundo cenário de provisionamento, nós vamos escrever a seguinte configuração do Fedora CoreOS em um arquivo chamado `fcct-containers.yaml`:

	The `Failed Units` message is coming from the https://github.com/coreos/console-login-helper-messages[console login helper messages] helpers. This particular helper shows us when `systemd` has services that are in a failed state. In this case we made `failure.service` with `ExecStart=/usr/bin/false`, so we intentionally created a service that will always fail in order to illustrate the helper messages.	A mensagem `Filed Units` vem do suport https://github.com/coreos/console-login-helper-messages[mensagens de suporte para login no console]. Esse suporte particular nos mostra quando o `systemd` possui serviços que estão em um estado de falha. Nesse caso nós fazemos `failure.service` com `ExecStart=/usr/bin/false`, então nós intencionalmente criamos um serviço que sempre falhará, no objetivo de ilustrar as mensagens de suporte.
	Now that we’re up and don’t have any real failures we can check out the status of `etcd-member.service`, which was generated from our `etcd-member.container` file.	Agora que estamos prontos e não temos falhas reais, nós podemos checar o serviço que nos importa (`etcd-member.service`):
