500 EOF error returned
Duane Crowley
Hello, everyone.
For testing purposes I’m running community KrakenD v2.8.0 in a docker container through docker desktop on my Windows laptop.
I have a healthcheck endpoint on one of my development APIs. The API server has a self signed certificate. I have the cert in the docker container. Here is my dockerfile I’m using to build the image (I redacted the name of the certificate)
FROM devopsfaith/krakend:latest
WORKDIR /etc/krakend
COPY certs/xxxxx-CA.crt /usr/local/share/ca-certificates/xxxxx-CA.crt
COPY krakend.json /etc/krakend/krakend.json
EXPOSE 8080
CMD ["run", "-c", "/etc/krakend/krakend.json", "-d"]
I can call the healthcheck endpoint from Postman without issue, but when I try to use KrakenD, I get this error (I redacted the servername):
2024-12-16 15:05:09 Error #01: Get https://xxxxx.com/health: EOF
Here is my configuration json with the server names redacted.
{

]
}
]
}
]
}
When using postman, I get this JSON response (I redacted server names)

}
}
I’m sure I’ve made a simple mistake, but I’m not seeing it. Any and all help is appreciated.

Sorry for posting. Hopefully my error will help someone else sometime.
