ping: unknown host www.google.com

# This file is managed by man:systemd-resolved(8). Do not edit.

# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

- Intenté reemplazarlo por 8.8.8.8/8.8.4.4 sin suerte
- hacer ping fuera del contenedor funciona
