Estoy escribiendo una tarea personalizada en Capistrano 3 (lib / capistrano / tasks / revision) que está obteniendo la revisión de una aplicación en ejecución mediante curl.
Luego compara la versión en ejecución con la última implementada y las compara, si no son las mismas, se debe lanzar un error.
Llegué al punto de que la revisión de la aplicación en ejecución se recupera y se compara con una cadena vacía para lanzar un error.
El problema que tengo es que el resultado de esta tarea no es bonito, es solo un texto en blanco.
¿Qué me estoy perdiendo? He estado cavando en la documentación todo el día.
¡Saludos!
revision.rake:
namespace :revision do
desc "Check revision of all applications to determine if the application is running the latest deployed revison"
task :check do
puts "Checking revision of all supported applications"
invoke "revision:httpapi"
end
task :httpapi do
on roles(:httpapi), in: :sequence do |host|
puts "Checking revision of httpapi on #{host}"
begin
response = capture "curl -L "http://#{fetch(:diagnostics_username)}:#{fetch(:diagnostics_password)}@#{host}/diagnostics/status?mode=extended&output=detailed""
object = JSON.parse(response, object_class: OpenStruct)
unless object.result.revision == "" #For test, just compare to empty string so error is thrown
raise "The running revision is not the same as the installed, please restart all applications"
end
rescue Exception => e
raise e.message
end
end
end
end

1 para la respuesta № 1Un buen ejemplo de un problema similar que se resuelve en el núcleo es aquí: https://github.com/capistrano/capistrano/blob/master/lib/capistrano/tasks/deploy.rake#L91
En ese sentido, probablemente querrás codificar algo como esto:
task :httpapi do
on roles(:httpapi), in: :sequence do |host|
puts "Checking revision of httpapi on #{host}"
response = capture "curl -L "http://#{fetch(:diagnostics_username)}:#{fetch(:diagnostics_password)}@#{host}/diagnostics/status?mode=extended&output=detailed""
object = JSON.parse(response, object_class: OpenStruct)
unless object.result.revision == "" #For test, just compare to empty string so error is thrown
error "The running revision is not the same as the installed, please restart all applications"
exit 1
end
end
end
