numero vagante

Question

Ho una VM fatta con vagabondo e chef. La scorsa notte il mio computer è stato riavviato inaspettatamente mentre la VM era attiva e funzionante. Dopo di che, quando provo a vagare su VM, ottengo: Lo chef non ha mai completato con successo! Eventuali errori dovrebbero essere visibili nell'output sopra. Per favore aggiusta le tue ricette in modo che si completino correttamente.

Answer 1

Questo è un bug nella ricetta dello chef stesso. Se leggi lo stacktrace, puoi vedere che l'errore si trova effettivamente sulla riga 114 della ricetta predefinita nel ricettario my-site. L'errore di Ruby che stai vedendo significa che stai tentando di fare qualcosa come a[:foo] dove a è nil. Naturalmente, non è possibile chiamare [] su nil.

Answer 2

Ho avuto lo stesso problema. Ho capito che la versione di chef che era in esecuzione nella mia VM era troppo vecchia (0.10.10).

Dovete aggiornarlo:

 
local$ vagrant ssh 
vagrant$ gem install chef 

e riprovare.

Answer 3

ho ricevuto gli errori:

Chef never successfully completed! Any errors should be visible in the 
output above. Please fix your recipes so that they properly complete. 

Error executing action `create` on resource 'mysql_service[default]' 

ho usato il:

local$ vagrant ssh 
vagrant$ gem install chef 

Dopo aver provato ancora una volta, tutto funzionava perfetto.
