示例1: PurgeSnapshots
func PurgeSnapshots(svc *ec2.EC2) error {
dsi := ec2.DescribeSnapshotsInput{}
filter := &ec2.Filter{}
filterName := "tag:" + PurgeAllowKey
filter.Name = &filterName
value := "true"
filter.Values = []*string{&value}
dsi.Filters = append(dsi.Filters, filter)
dso, err := svc.DescribeSnapshots(&dsi)
if err != nil {
return fmt.Errorf("describeSnapshots error, %s", err)
}
purgeCount := 0
for _, snapshot := range dso.Snapshots {
var paVal string
var found bool
if paVal, found = getTagValue(PurgeAfterKey, snapshot.Tags); !found {
log.Printf("snapshot ID %s has tag '%s' but does not have a '%s' tag. Skipping purge...", *snapshot.SnapshotId, PurgeAllowKey, PurgeAfterKey)
continue
}
pa, err := time.Parse(PurgeAfterFormat, paVal)
if err != nil {
return err
