Fleet Server - * missing enrollment api key

bevano · September 4, 2021, 9:06am

Hey All,

Recently upgraded to 7.14.1 to and am struggling to install fleet server. I am running on-prem and have my self-signed certs setup. Trying to install fleet-server on the same node where elasticsearch is installed. The IP of this server is 192.168.117.101, my Kibana instance is 192.168.117.11

From the logs, I'm guessing it a problem with a certificate and being able to access Kibana/Elasticsearch to get an enrollment key? Not too sure where I can start looking since I have followed all the documentation: Encrypt traffic in a self-managed cluster | Fleet User Guide [7.14] | Elastic

I am installing it via this command

sudo /root/elastic-agent/elastic-agent enroll -f --insecure \
  --url=https://192.168.117.101:8220 \
  --fleet-server-es=https://192.168.117.101:9200 \
  --fleet-server-service-token=AAEAAWVsYXN0aWMvZmxlZXQtc2VydmVyL3Rva2VuLTE2MzA3NDA3NTM5ODQ6OTFkRm1FdXBRbXlwLWk4R3Nyd1p0UQ \
  --fleet-server-policy=0d8b9ba0-0ce5-11ec-8978-2bc18b6d481d \
  --certificate-authorities=/etc/elasticsearch/other/ca/ca.crt \
  --fleet-server-es-ca=/etc/elasticsearch/other/elasticsearch-ca.crt \
  --fleet-server-cert=/etc/elasticsearch/other/fleet-server/fleet-server.crt \
  --fleet-server-cert-key=/etc/elasticsearch/other/fleet-server/fleet-server.key

The output from the console is

error  indicates a PEM file to be loaded not being a valid PEM file or certificate.

can you double check on that?

Vergil · September 21, 2021, 1:51pm

@Michal_Pristas, I am also getting "missing enrollment api key" when trying to install fleet server 7.14.1 on the same node where elasticsearch and kibana are installed.

Please look into this matter.

Have you tried removing the agent completely, installing the elastic agent and then enrolling the policy with the Fleet server ?

This worked for me after Endpoint Security screwed up my installation

Vergil · September 21, 2021, 2:48pm

I was following their guide on Add a Fleet Server.

Do you mean to start again with creating a default Fleet Server policy?

zx8086 · September 21, 2021, 3:03pm

If it is not an issue, it is an easier way to say wasting time troubleshooting a problem that might be a needle in a haystack.

Vergil · September 22, 2021, 6:04am

Did everything again. Just ran into different errors.
Bottom line - The --insecure flag does not work in latest versions.

bevano · September 23, 2021, 5:47am

Hey Vergil,

So I re-issued all my certificates (I had to since they were expiring in 6 months) and it worked. I didn't need to use the insecure flag. What I also had to add was a "--fleet-server-service-token". This is the specific command I ran to enroll it - I have blocked our all the confidential parts.

/root/elastic-agent/elastic-agent enroll --url=https://192.168.0.2:8220 \
  -f \
 --fleet-server-es=https://192.168.0.2:9200 \
 --fleet-server-service-token=THIS_WAS_90_CHARACTERS_OF_CAPITALS_LOWERCASE_AND_NUMBERS \
 --fleet-server-policy=THISWAS-NUMBERS-AND-CHARACTERS- \
 --certificate-authorities=/root/elastic-agent/ca.crt \
 --fleet-server-es-ca=/root/elastic-agent/ca.crt \
 --fleet-server-cert=/root/elastic-agent/fleet-server.crt \
 --fleet-server-cert-key=/root/elastic-agent/fleet-server.key

After running that, I was able to start it with

systemctl start elastic-agent

You can also check the status - which I found useful by typing

elastic-agent status

My cluster also started around version 7.4, so I had Beat Management (the management thing prior to fleet-server). I had to delete various API tokens before some Fleet-Server features came up.

Vergil · September 23, 2021, 10:47am

So, you just re-issued all your certificates and it worked.

bevano · September 27, 2021, 1:22pm

Yep. Probably didn’t do my certificates correctly the first time (didn’t have much SSL knowledge)

bevano · October 1, 2021, 3:33pm

Is your fleet server CA different from your elastic CA?

Maybe try this for the fleet server config within Kibana. I also had to copy the certificate into the output part.

Section 1 e. Under “Configure Fleet settings”

https://www.elastic.co/guide/en/fleet/current/secure-connections.html

Vergil · October 1, 2021, 5:22pm

Don't worry. My issue got solved just by again creating certs for the fleet server.
