¿Cambiar a otra instancia de Redis?

Soporte Instalación
1

Mi instancia de Discourse utilizaba anteriormente una instancia compartida de Redis con otras aplicaciones. Ahora quiero que Discourse use su propia instancia de Redis. ¿Puedo simplemente editar la configuración YML, arrancar una nueva imagen, reiniciar el contenedor y esperar a que todo funcione bien?

Recibo el siguiente error al arrancar la nueva imagen:

I, [2019-09-09T16:58:33.448153 #1]  INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate'

No estoy seguro de si es necesario migrar los datos de la instancia antigua de Redis para que funcione.

2

Asegúrate de que el contenedor pueda alcanzar esa dirección IP.

No es necesario.

Parece que un contenedor normal (en lugar de pods de Kubernetes) no puede conectarse a un ClusterIP de Kubernetes. Intenté conectarme a mi nueva instancia de Redis usando redis-cli en un contenedor de Redis y falló. Sin embargo, puedo conectarme a la instancia de Redis en el host. ¿Cuál es la forma recomendada de construir en un entorno de Kubernetes?

Proporcionamos métodos estándar para conectarse a bases de datos fuera del contenedor de la aplicación, como Configure Discourse to use a separate PostgreSQL server. Los detalles de la red en esas configuraciones avanzadas dependen de ti, ya que variarán enormemente según tu implementación.

Ya ofrecemos una instalación extremadamente sencilla para todos en discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub, que funciona y da soporte a miles de instancias en internet. Me temo que quienes opten por seguir su propio camino deberán asumir las consecuencias, ya que es imposible para nosotros brindar soporte para todas las combinaciones posibles.

Para cualquiera que se haya encontrado con el mismo problema, finalmente usé ./launcher bootstrap web_only --docker-args "--network=host" para solucionarlo. Parece que un nodo host de k8s puede conectarse a un ClusterIP, mientras que un contenedor Docker normal (que no es un pod de k8s) no puede.
