Mantener el horario del SO en un contenedor

Para que el contenedor mantenga el horario del SO es necesario agregar lo siguiente en el volumen del mismo. 

- "/etc/timezone:/etc/timezone:ro"
- "/etc/localtime:/etc/localtime:ro"

En este ejemplo vemos la forma de hacerlo en un docker-compose. Obviamente el SO tiene que tener bien configurado el horario. 

proteger vistas en tu wordpress

Un buen plugin de wordpress cuando tenes un sitio publico en donde estas trabajando y no queres que cualquiera lo pueda visualizar.
