Getting 404

[shammishailaj]

I have set-up bulldozed using docker. The command being used to run the docker container is:

docker run -it -d --restart unless-stopped -v /path/to/bulldozer.yml:/secrets/bulldozer.yml -p 8400:8400 --name bulldozer palantirtechnologies/bulldozer:latest

Nginx reverse proxy has been set-up on xyz.example.com which routes traffic to the docker container running on http://localhost:8400

When I try to access the http://xyz.example.com , I am getting a 404 from the container. When I am trying to hit http://xyz.example.com/api/github/hook , I am getting a 404 again.

Can someone explain what I am doing wrong here?

Hi @shammishailaj 👋 ,

Looking at the information you've given it's a bit hard to say what might be going wrong. Although, here are some thoughts on what could be wrong.

• There is no "root" page for bulldozer, so a GET on http://xyz.example.com would return a 404. See #107
• If you do a GET on http://xyz.example.com/api/github/hook, you'll most likely also get a 404 as it's expecting a POST as this is what GitHub will do
• The nginx reverse proxy configuration might not be correct. You mentioned you get the 404s from the container; was this done via the proxy or directly through the container?

Hopefully these can help you get pointed in the right direction 🙂

Hi @jamestoyer

Thanks for your insights. :)

Points 1 and 2 make total sense. Will try to set-up a webhook and see if that works.

Also, will it be possible for you to share a sample POST request, if that is not too much to ask for. The Nginx proxy is configured properly as hits were reaching the container and the container logs were showing 404 as well.

Hi @jamestoyer

Should I use JSON as the content-type in Github Webhook setting or application/x-www-form-urlencoded ?

[shammishailaj]

I have tried with both application/x-www-form-urlencoded and application/json

In both cases the server is returning 500 to Github. Please see the docker logs below

Please help

I think you've almost got it working. The error seems to be the same as the one in #85

as @bluekeyes said:

This latest error can happen if the webhook_secret value in the Bulldozer configuration file does not match the value configured in the GitHub App. You can set the value used by GitHub on the settings page for your app. The actual value is arbitrary, so I recommend generating a random 32 character string.

Let us know if that solves your problem.

[shammishailaj]

Yes that did solve it. I had configured the Webhook Secret in bulldozer.yml but had not mentioned it in the repository's webhook settings.

Thanks to both @asvoboda and @jamestoyer
