## Let's Encrypt

Antes de Let's Encrypt, esses certificados HTTPS eram vendidos por terceiros confiáveis.

O processo de aquisição de um desses certificados costumava ser complicado, exigia bastante papelada e os certificados eram bastante caros.

Mas então <a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a> foi criado.

	If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
		- 'systemctl status kubelet'
		- 'journalctl -xeu kubelet'

	Additionally, a control plane component may have crashed or exited when started by the container runtime.
	To troubleshoot, list all containers using your preferred container runtimes CLI.
	Here is one example how you may list all running Kubernetes containers by using crictl:

    done
  fi
  kube::log::error_exit "Error in ${BASH_SOURCE[1]}:${BASH_LINENO[0]}. '${BASH_COMMAND}' exited with status ${err}" "${1:-1}" 1
}

kube::log::install_errexit() {
  # trap ERR to provide an error handler whenever a command exits nonzero  this
  # is a more verbose version of set -o errexit
  trap 'kube::log::errexit' ERR
