Import a DNS zone file into a Project, or preview it with dry-run

POST/v2/projects/{projectId}/dns-zone-imports/
API version
v2
Request method
POST
Operation ID
dns-create-dns-zone-file-import

Parses an uploaded RFC-1035 zone file and returns the structured import plan: the importable target DNSZones (one per distinct owner name, with the record sets that would be set) plus a flat list of conflicts explaining everything that will not be imported (invalid records, unsupported record types, CNAME conflicts, placement problems, parse errors). With dryRun=true this is all it does — a side-effect-free preview, nothing is created. Otherwise it also starts the import and returns the created job id. The import is all-or-nothing: if the zone file has any conflict the request is rejected with 412 and no job is created — resolve the conflicts (visible in the dry-run preview) and retry, since a half-imported zone file would leave DNS in a confusing half-state. An identical import still running for the project is rejected with 409. Existing zones are overwritten. Poll GET /v2/dns-zone-imports/{zoneFileImportId} for status.

Request​

  • projectIdstring
    required

    ID of the Project to import into.

Beschreibung

The import plan (zones + conflicts); on a real import also the created job id.

  • conflictsarray of object
    required

    Everything that will not be imported (invalid records, unsupported record types, CNAME conflicts, placement problems, parse errors). Empty on a real import, since any conflict rejects the whole import with 412 (all-or-nothing).

    • Array[
      • *object
        • codestring (one of: parseError, invalidRecord, invalidZoneName, unsupportedRecordType, cnameConflict, foreignCustomerIngress, rootZoneUnavailable)
          required

          Machine-readable conflict kind: parseError (a zone-file line could not be parsed), invalidRecord (a record failed the same schema validation the write commands apply), invalidZoneName (the owner name is not a valid zone name, e.g. a wildcard *.example.com), unsupportedRecordType (an RR type dns-service does not import), cnameConflict (a CNAME shares a name with other record types), foreignCustomerIngress (the zone's enabled ingress belongs to another organization), rootZoneUnavailable (a subzone whose root zone is neither importable nor already existing).

        • messagestring
          required

          Human-readable explanation of the conflict, suitable for surfacing to the user.

        • namestring

          Offending record/owner name. Empty for a file-level parse error, where sourceLine locates the bad line.

        • recordstring

          Only on an invalidRecord conflict: the offending record's rendered value (e.g. "10 ." for an MX).

        • recordSetTypestring (one of: a, mx, txt, cname, srv, caa)

          Only on an invalidRecord conflict: the offending record's set type.

        • sourceLineinteger (int64)

          1-based line number in the uploaded zone file, set for a file-level parse error (code parseError); 0 otherwise.

      ]
  • idstring (uuid)

    ID of the started import job. Absent on a dry-run (dryRun=true), which creates no job.

  • zonesarray of object
    required

    The importable target zones (one per distinct owner name), each with the record sets that would be set. On a dry-run this is the preview; on a real import it is the plan that was applied.

    • Array[
      • *object
        • alreadyExistsboolean
          required

          Whether a zone with this name already exists. On import its record sets are overwritten rather than the import failing.

        • namestring
          required

          Fully-qualified name of the target zone. Every distinct owner name becomes its own zone. Only importable zones are listed; a zone named by a conflict is omitted.

        • recordSetsarray of object
          required

          The record sets that would be set on the zone — one per record type present for this owner name.

          • Array[
            • *object
              • recordsarray of object
                required

                The individual records in the set.

                • Array[
                  • *object
                    • flagsinteger (int32)

                      CAA flags. Only set for CAA records.

                    • portinteger (int32)

                      SRV port. Only set for SRV records.

                    • priorityinteger (int32)

                      MX preference / SRV priority. Only set for MX and SRV records.

                    • tagstring

                      CAA tag (e.g. issue, issuewild, iodef). Only set for CAA records.

                    • valuestring
                      required

                      The record's value: an IP address for A/AAAA, the target FQDN for MX/CNAME/SRV, the text for TXT, the value for CAA.

                    • weightinteger (int32)

                      SRV weight. Only set for SRV records.

                  ]
              • ttlNormalizedboolean
                required

                True when the source TTLs had to be normalized to ttlSeconds — because they diverged within the set or fell below the 60s minimum. Informational; the import still uses ttlSeconds.

              • ttlSecondsinteger (int32)
                required

                TTL applied to the whole set, in seconds. Collapsed to a single value across the set: the minimum of the source TTLs, floored to the 60s minimum.

              • typestring (one of: a, mx, txt, cname, srv, caa)
                required

                Record-set type.

            ]
        • targetProjectIdstring
          required

          Project the zone would be created in. Always set, since only importable zones are listed.
