Can't get Kong 0.14.0 to serve my certificates on HTTPS #3721

itaimalek · 2018-08-22T12:20:35Z

Summary

After configuring Certs with SNIs Kong route is ignoring the configuration and serves localhost cert (default)

Steps To Reproduce

Configure .pem and .key strings to Certificate resource in Kong with SNI
Configure a Service and Route objects with Host in Route as in above SNI with https enabled for the Route
Try to access via https

Expected result

Kong will serve the certificate that it's SNI fits the Host of the Route.

Additional Details & Logs

Kong version - 0.14.0
setup is on kubernetes with postgres DB.
HTTP access is good- I get response as expected.

my Service object:

{
            "host": "some.service.domain",
            "connect_timeout": 60000,
            "id": <service-id>,

}

my SNI object:

                "id": <cert object ID>
            },
            "created_at": 1534852534,

How did you add the certificate(s) to Kong?

itaimalek · 2018-08-22T17:22:20Z

Hi, Thanks for replying, I added certificates just like any other object, via kong admin api.

ionosphere80 · 2018-08-22T17:26:34Z

Right... but did you use a JSON file with the application/json content type?

itaimalek · 2018-08-22T17:45:07Z

yes, I did a POST request with body like:

{ "cert": "<.pem file content>", "key": "<key file content>", "snis": [ "<host.some.domain>" ] }
also, the SNI was created from this request.
I didn't use a json file, the JSON object was sent via the request itself.
Also when doing GET to kong-admin-api/certificates, I can see my certificate there.

ionosphere80 · 2018-08-22T18:05:40Z

Did your certificate contain \n in place of CRs?

itaimalek · 2018-08-22T18:21:50Z

Did your certificate contain \n in place of CRs?
.
nope -verified that.

you can see Kong is serving a default certificate:

ionosphere80 · 2018-08-22T18:24:50Z

If using JSON, the certificate and key objects should use \n in place of CRs. The Kong API has a tendency to accept certificates/keys with an incorrect format, but won't enable them.

itaimalek · 2018-08-22T18:36:00Z

NICE !
That did it !

Thanks allot !

ionosphere80 · 2018-08-22T18:37:37Z

No problem. Kong should do a better job of validating body content.

benjaminprojas · 2018-09-19T14:06:00Z

I am having the same symptoms as the original issue here. My certificates are being loaded properly (I think), and yet kong isn't picking them up. When it returns the created or updated response, I see the line breaks are \n like @ionosphere80 mentioned.

I used to add these certificates in 0.13.x like this:

curl -i -X POST http://localhost:8001/certificates/ \
  -F 'cert=@/link/to/cert.pem' \
  -F 'key=@/link/to/key.pem' \
  -F 'snis=domain.com'

But if I do that now, it returns a "missing key" error. If I use JSON instead, it seems to load just fine, but it doesn't use it properly on the endpoint. Anything I am missing here?

benjaminprojas · 2018-09-19T14:09:49Z

I forgot to mention the way I am doing it now:

curl -i -X POST http://localhost:8001/certificates/ \
  -H 'Content-Type: application/json' \
  -d "{\"cert\": \"$(cat /link/to/cert.pem")\", \"key\": \"$(cat /link/to/key.pem")\", \"snis\": [ \"domain.com\" ] }"

benjaminprojas · 2018-09-19T16:10:15Z

Never mind, turns out I was generating the certs improperly. Thanks!

DevOpsRoot · 2018-10-08T08:11:45Z

Thanks @benjaminprojas, you save my day 💯

bungle · 2018-10-17T09:16:18Z

I feel like this is resolved now. Btw. the multipart/form-data support was added back with this (well 80% solution, but should work especially for this case):
#3776

xiaoshumiao6 · 2019-04-10T11:24:16Z

that is a so big trap

cmutrufflepig · 2021-03-18T06:52:45Z

I forgot to mention the way I am doing it now:

curl -i -X POST http://localhost:8001/certificates/ \
  -H 'Content-Type: application/json' \
  -d "{\"cert\": \"$(cat /link/to/cert.pem")\", \"key\": \"$(cat /link/to/key.pem")\", \"snis\": [ \"domain.com\" ] }"

Thank you! This is the only way that worked after an hour of trying.
One small thing though, the double quotes immediately after /link/to/xxx.pem are redundant. Saves other people a few minute.
