是否可以使用 Java AWS API 更新 Route53 记录？

Question

I have a hosted domain on AWS Route53. Under that domain I have an 'A' record for a subdomain.

I would like to be able to update the IP address of the 'A' record using the Java API. However, when looking at the setAction method of the com.amazonaws.services.route53.model.Change class, it only accepts the CREATE or DELETE values. This seems to match the allowed values in the XML message that the Java API sends behind the scenes.

Is there any way to just update the IP address, or do I have to delete the original record and then create it again?

Thanks

Answer 1

It worked for me using this piece of code:

ResourceRecord record = new ResourceRecord(loadBalancer);
List<ResourceRecord> records = new ArrayList<ResourceRecord>();
records.add(record);
ResourceRecordSet recordsSet = new ResourceRecordSet();
recordsSet.setResourceRecords(records);
recordsSet.setType(RRType.CNAME);
recordsSet.setTTL(900L);
recordsSet.setName(subdomain + ".");
Change change = new Change(ChangeAction.CREATE, recordsSet);
List<Change> changes = new ArrayList<Change>();
changes.add(change);
ChangeBatch batch = new ChangeBatch(changes);
ChangeResourceRecordSetsRequest request = new ChangeResourceRecordSetsRequest();
request.setChangeBatch(batch);
request.setHostedZoneId(hostedZoneId);
ChangeResourceRecordSetsResult result = getRoute53Client().changeResourceRecordSets(request);
System.out.println(result);

Just replace the variables I used with proper data. (subdomain, loadBalancer and hostedZoneId). The method getRoute53Client() returns an instance of the AmazonRoute53Client class from the AWS API.

The only way is to use DELETE / CREATE sequence as mentioned here .

Creating a Change Batch Request

To create a change batch request, use the ChangeResourceRecordSets action ChangeBatch element. You use CREATE and DELETE actions within the ChangeBatch element for each record that you want to update. If you are only creating records, then you will only use CREATE actions.

        ResourceRecord rr = new ResourceRecord(IPAdress); // IPAddress will be String variable that has IP value
        List<ResourceRecord> rrList = new ArrayList<ResourceRecord>();
        rrList.add(rr);

        // Create a ResourceRecordSet
        ResourceRecordSet resourceRecordSet = new ResourceRecordSet();
        resourceRecordSet.setName(domainName); //domainName is String value of your domain
        resourceRecordSet.setType(RRType.A); //type of ResourceRecordSet
        resourceRecordSet.setTTL(new Long(300));
        resourceRecordSet.setWeight(new Long(0));
        resourceRecordSet.setResourceRecords(rrList);

        // Create a change
        Change change = new Change(ChangeAction.CREATE, resourceRecordSet);
        List<Change> changesList = new ArrayList<Change>();
        changesList.add(change);

        // Create a change batch
        ChangeBatch changeBatch = new ChangeBatch(changesList);

        // Create ChangeResourceRecordSetRequest.
        ChangeResourceRecordSetsRequest request = new ChangeResourceRecordSetsRequest(hostedZoneID, changeBatch); //hostedZoneId is variable that is the id of HostedZone

        // Send the request and get the response.
        ChangeResourceRecordSetsResult result = amazonRoute53Client.changeResourceRecordSets(request);

        // Print the result
        System.out.println(result.getChangeInfo());

hostedzoneId = " hosted zone id from the route53 " aliasTargetHostedzoneId = " zone id of the connected resource such as loadbalancer, cloudfront etc.. "

Route53Client route53Client = Route53Client.builder()
            .credentialsProvider(StaticCredentialsProvider.create(awsCreds))
            .region(Region.AWS_GLOBAL)
            .build();


    AliasTarget aliasTarget = AliasTarget.builder()
            .dnsName(loadBalancerDomain)
            .evaluateTargetHealth(false)
            .hostedZoneId(aliasTargetHostedzoneId)
            .build();

    // Create a ResourceRecordSet
    ResourceRecordSet resourceRecordSet = ResourceRecordSet.builder()
            .name(fullDomainName+".")
            .type(RRType.A)
            .aliasTarget(aliasTarget)
            .build();


    // Create a change
    Change change = Change.builder()
            .action(ChangeAction.CREATE)
            .resourceRecordSet(resourceRecordSet)
            .build();

    List<Change> changesList = new ArrayList<Change>();
    changesList.add(change);

    // Create a change batch
    ChangeBatch changeBatch = ChangeBatch.builder()
            .changes(changesList)
            .build();

    // Create ChangeResourceRecordSetRequest.
    ChangeResourceRecordSetsRequest request = ChangeResourceRecordSetsRequest.builder()
            .hostedZoneId(hostedzoneId)
            .changeBatch(changeBatch)
            .build();

    // Send the request and get the response.
    ChangeResourceRecordSetsResponse result = route53Client.changeResourceRecordSets(request);
