Con un piccolo forum (backup da 500 MB), il mio ./launcher rebuild fallisce su un disco da 50 GB a causa dell’esaurimento dello spazio. Mentre cercavo di capire cos’altro pulire (apt autoremove e ./launcher cleanup non hanno prodotto risultati), ho trovato diverse centinaia di megabyte di locale inutili in /var/lib/docker/overlay2/.../merged/var/www/discourse/public/assets/locales.
Sfortunatamente ho iniziato a cancellarli prima di fare lo screenshot, ma si possono ancora vedere molti file JS duplicati apparentemente trascritti per la stessa lingua. Si può fare qualcosa nel codice di Discourse per evitarlo? I file .map sono usati per qualcosa?
Inoltre, il mio forum usa solo l’inglese. Come posso escludere tutte le altre lingue?
La directory /var/www/discourse/public all’interno del container non è montata sull’host… quindi sono abbastanza sicuro che vengano tutte eliminate ogni volta che esegui ./launcher rebuild app in un’installazione standard.
Il server sta effettivamente eseguendo solo Discourse.
Ho eseguito i comandi, ho riscontrato alcuni errori relativi alle localizzazioni e ora l’output è bloccato su FATAL: database files are incompatible with server. The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 15.12.
Ho accidentalmente cancellato qualche file di localizzazione importante? en_US.UTF-8 è stato apparentemente rigenerato con successo.

2025-04-03 17:28:39.091 UTC [51] FATAL: database files are incompatible with server
2025-04-03 17:28:39.091 UTC [51] DETAIL: The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 15.12 (Debian 15.12-1.pgdg120+1).

Sì, in quel caso persisteranno. Ma forziamo gli aggiornamenti CLI almeno una volta ogni 6 mesi, quindi non mi aspetto che sia un grosso problema.
Per quanto riguarda le localizzazioni, stiamo pianificando di apportare alcune modifiche in modo che vengano compilate “just in time” alla prima richiesta. Dovrebbe essere molto più efficiente, dato che la maggior parte dei siti opera in una sola lingua.
Il server ha 2 GB di RAM. Lo swap è impostato su altri 2 GB.
L’ho aggiornato da Ubuntu 16 (lo so) a 18 in loco, ho aggiornato /var/discourse/containers/app.yml per contenere le tre impostazioni di locale env, e ora la migrazione di PostgreSQL da v13 è riuscita, e l’ultima versione di Discourse sembra funzionare correttamente su Ubuntu 18.
