A reçu 0 Signaux avec succès 1. Il est impossible de satisfaire l'exigence 100% MinSuccessfulInstancesPercent

Je commence ce motif dans le cloud pour créer une échelle automatique en voiture ubuntu-18.04, Et cela réduira automatiquement toutes les instances créées par ce modèle et émettra une telle erreur.

A reçu 0 Signaux Le succès est 1. Il est impossible de satisfaire l'exigence 100% MinSuccessfulInstancesPercent. Impossible de créer les ressources suivantes: [WebServerGroup]. . La restauration est demandée par l'utilisateur.

S'il vous plaît laissez-moi savoir s'il y a des problèmes avec ce modèle ou cette commande. CFN, J'utilise ça

Confirmation de:

Simplifiez-le.

Pour démarrer, supprimez tous les éléments de zoom ALB et CloudWatch.

Désactiver (Effacer)

CreationPolicy

et

UpdatePolicy

Pour empêcher l'erreur que vous voyez. Avec cette télécommande ASG N'y aura pas de signal de dépenses. Après cela, l'instance doit démarrer et rester en état de fonctionnement.

SSH Par exemple

et vérifiez quelles erreurs vous voyez dans

/var/log/cloud-init.log

et

/var/log/cloud-init-output.log

- cela vous donnera comprendre ce qui se passe avec une erreur et pourquoi il ne peut pas envoyer

cfn-signal

Le succès est retourné à B. AWS.

Résoudre le problème de

et retourne aux articles 1 et 2 Ci-dessus et essayez à nouveau.

J'espère que cela aidera :)
