(vert.x-eventloop-thread-1) Unable to look up TXT record for host serverlessinstance0.oagmp.mongodb.net

[marcogutto]

Describe the bug

I get the error:
(vert.x-eventloop-thread-1) Unable to look up TXT record for host serverlessinstance0.oagmp.mongodb.net.

In my contaiver resolv.conf file:

bash-4.4$ cat /etc/resolv.conf
nameserver 127.0.0.11
options ndots:0

I'm using the native image quay.io/quarkus/quarkus-micro-image:1.0.

It comes with ndots:0 by default.

Thanks in advance!

Expected behavior

It find in native mode the look up TXT record for host serverlessinstance0.oagmp.mongodb.net.

Actual behavior

It doesn't find the look up TXT record for host serverlessinstance0.oagmp.mongodb.net.

I'm aware of a few issues regarding the dns resolution. That's why the feature is experimental.
I don't have a good solution at the moment unfortunately.

[cescoffier]

Got an idea, let me see if this is going to work or .... not

[cescoffier]

Ok, I'm not able to test against an Atlas serverless instance, but I got a native application connecting to a shared instance using both the -micro and -native base images.

Workaround:

1. Reference:
   https://www.appsloveworld.com/mongodb/100/53/failed-to-import-the-uri-unable-to-look-up-txt-record-for-host-cluster0-ohzuo-mo

2. application.properties template:

spring.data.mongodb.uri=mongodb://" + USER + ":" + PASS + "@" + HOST + ":" + PORT + "/" + DB
spring.data.mongodb.database=DB

3. application.properties example:

spring.data.mongodb.uri=mongodb://userA:[email protected]:27017/db_name?ssl=true&replicaSet=atlas-rw4866-shard-0&authSource=admin&retryWrites=true&w=majority
spring.data.mongodb.database= db_name
