Obtention de tous les détails d'instantané et de volume du compte AWS à l'aide d'AWS lambda et python sdk

Question

Bonjour, J'essaie d'obtenir tous les détails d'instantanés et de volumes à partir du compte AWS. Mon code fonctionne parfaitement, mais je ne sais pas, pour une raison ou une autre, qu'il montre l'instantané et le volume de la région 'us-east-1' et 'ap-southeast-1'. Cependant, j'ai des ressources disponibles dans d'autres régions également.

J'ai découvert l'erreur dans mon code. La valeur de ligne Everytime a été mise à jour à 1 dans la section "pour la région dans les régions:" et, par conséquent, je n'obtenais que deux valeurs de région. J'ai donc déclaré 2 valeurs différentes pour la ligne et la colonne de la boucle d'instantané et de la boucle de volume.Ainsi, la solution a été déclarée rowSnap = 1 rowVol = 1 séparément et cela a fonctionné correctement.

rowSnap=1 
rowVol=1 
regions = ec.describe_regions().get('Regions',[]) 
for region in regions: 
    reg=region['RegionName'] 
    regname='REGION :' + reg 
    # print regname 
    ec2 = boto3.client('ec2',region_name=reg) 
    snapshots=ec2.describe_snapshots(OwnerIds=['**',],).get('Snapshots',[]) 
    if len(snapshots) >0 : 
     print "snapshots : " + str(len(snapshots)) + " " + reg 
     j=1 
     col=0 
     while j <= len(snapshots): 
      for i in snapshots: 
        date1 = i['StartTime'].strftime('%Y-%m-%d') 
        worksheet1.write(rowSnap,col,i['VolumeId']) 
        worksheet1.write(rowSnap,col+1,i['SnapshotId']) 
        worksheet1.write(rowSnap,col+2,date1) 
        worksheet1.write(rowSnap,col+3,i['Description']) 
        worksheet1.write(rowSnap,col+4,i['VolumeSize']) 
        worksheet1.write(rowSnap,col+5,reg) 
        rowSnap +=1 
        j=j+1 
    ec2volumes = ec2.describe_volumes().get('Volumes',[]) 
    if len(ec2volumes) >0 : 
     #if reg=='ap-south-1': 
     print "volumes : " + str(len(ec2volumes)) + " " + reg 
     j=1 
     col=0 
     while j <= len(ec2volumes): 
      # row=0 
      # col=0 
      for i in ec2volumes: 
        worksheet2.write(rowVol,col,i['VolumeId']) 
        worksheet2.write(rowVol,col+1,i['State']) 
        worksheet2.write(rowVol,col+2,i['Size']) 
        worksheet2.write(rowVol,col+3,reg)
