	This could be useful in cloud environments where you might have different public and private addresses.	Isso pode ser útil em ambientes de nuvem onde você poderá encontrar diferentes endereços públicos e privados.
	We will store this script into `/usr/local/bin/public-ipv4.sh` when we provision the machine.	Nós vamos armazenar esse script em `/usr/local/bin/public-ipv4.sh` quando provisionarmos a máquina.
	Writing the systemd service	Escrevendo o serviço do systemd
	We need to call the script from the previous section by using a systemd unit. Let's write a systemd unit into the `issuegen-public-ipv4.service` file that does what we want, which is to execute on first boot and not again:	Nós precisamos chamar o script da seção anterior usando uma unidade o sytemd, Aqui está uma que funciona para o que queremos, que é executar somente na primeira inicialização e não novamente:
	cat <<'EOF' > issuegen-public-ipv4.service [Unit] Before=systemd-user-sessions.service Wants=network-online.target After=network-online.target ConditionPathExists=!/var/lib/issuegen-public-ipv4	[Unit] Before=console-login-helper-messages-issuegen.service After=network-online.target ConditionPathExists=!/var/lib/issuegen-public-ipv4
	[Service] Type=oneshot ExecStart=/usr/local/bin/public-ipv4.sh ExecStartPost=/usr/bin/touch /var/lib/issuegen-public-ipv4 RemainAfterExit=yes	[Service] Type=oneshot ExecStart=/usr/local/bin/public-ipv4.sh ExecStartPost=/usr/bin/touch /var/lib/issuegen-public-ipv4 RemainAfterExit=yes
	[Install] WantedBy=multi-user.target EOF
	Writing the Butane config and converting to Ignition	Escrevendo a configuração Fedora CoreOS e convertendo para Ignition
	We can now create a Butane config that will include the script and systemd unit file contents by picking up the local `public-ipv4.sh` and `issuegen-public-ipv4.service` files using local file references. The final Butane config, stored in `services.bu`, will be:	Nós podemos agora criar uma configuração FedoraCoreOS incluindo o script e a unidade do systemD diretamente no conteúdo inline dentro das seções systemd/units e storage/files. A configuração final Fedora CoreOS, armazenada em `fcct-services.yaml` será:
	variant: fcos version: {butane-latest-stable-spec} systemd: units: - name: serial-getty@ttyS0.service dropins: - name: autologin-core.conf contents: \| [Service] # Override Execstart in main unit ExecStart= # Add new Execstart with `-` prefix to ignore failure` ExecStart=-/usr/sbin/agetty --autologin core --noclear %I $TERM - name: issuegen-public-ipv4.service enabled: true contents_local: issuegen-public-ipv4.service storage: files: - path: /etc/hostname mode: 0644 contents: inline: \| tutorial - path: /etc/profile.d/systemd-pager.sh mode: 0644 contents: inline: \| # Tell systemd to not use a pager when printing information export SYSTEMD_PAGER=cat - path: /usr/local/bin/public-ipv4.sh mode: 0755 contents: local: public-ipv4.sh	[Install] WantedBy=console-login-helper-messages-issuegen.service storage: files: - path: /etc/hostname mode: 0644 contents: inline: \| tutorial - path: /etc/profile.d/systemd-pager.sh mode: 0644 contents: inline: \| # Diz ao sytemD para não usar um paginador quando estiver imprimindo informações export SYSTEMD_PAGER=cat - path: /etc/sysctl.d/20-silence-audit.conf mode: 0644 contents: inline: \| # Aumenta o nível de logging de DEBUG(7) para WARNING(4) # para esconder mensagens de auditoria do console interativo kernel.printk=4 - path: /usr/local/bin/public-ipv4.sh mode: 0755 contents: inline: \| #!/bin/bash echo "Detected Public IPv4: is $(curl https://ipv4.icanhazip.com)" > \ /run/console-login-helper-messages/issue.d/50_public-ipv4.issue
	Check the Butane https://coreos.github.io/butane/examples/[Examples] and https://coreos.github.io/butane/specs/[Configuration specifications] for more details about local file includes.
	With the files `public-ipv4.sh`, `issuegen-public-ipv4.service`, and `services.bu` in the current working directory we can now convert to Ignition:
	butane --pretty --strict --files-dir=./ services.bu --output services.ign	fcct --pretty --strict fcct-services.yaml --output services.ign
	Testing	Testando
	Just as before we will use the following to boot the instance:	Assim como antes, vamos usar o seguinte para inicializar a instância:
	# Setup the correct SELinux label to allow access to the config chcon --verbose --type svirt_home_t services.ign	# Configura o rótulo correto do SELinux para permitir acesso à configuração chcon --verbose --type svirt_home_t containers.ign
	# Start a Fedora CoreOS virtual machine virt-install --name=fcos --vcpus=2 --ram=2048 --os-variant=fedora-coreos-stable \ --import --network=bridge=virbr0 --graphics=none \ --qemu-commandline="-fw_cfg name=opt/com.coreos/config,file=${PWD}/services.ign" \ --disk=size=20,backing_store=${PWD}/fedora-coreos.qcow2	# Inicia uma máquina virtual do Fedora CoreOS virt-install --name=fcos --vcpus=2 --ram=2048 --os-variant=fedora-coreos-stable \ --import --network=bridge=virbr0 --graphics=none \ --qemu-commandline="-fw_cfg name=opt/com.coreos/config,file=${PWD}/services.ign" \ --disk=size=20,backing_store=${PWD}/fedora-coreos.qcow2
	And view on the console that the `Detected Public IPv4` is shown in the console output right before you are dropped to a login prompt:	E ver no console serial que o `Detected Public IPv4` é mostrado na saída do console serial logo antes de você ser encaminhado para um prompt de login:
