tl;dnr
I can not get my docker-compose Envoy API gateway to properly forward to referenced services.
"Forwarded routes" always end up with the error:
upstream connect error or disconnect/reset before headers. reset reason: connection termination
I must have mucked up something simple since this is so difficult to resolve. Any additional assistance would be appreciated.
Apologies for the length, the nitty-gritty!
Hello folks, this is the first time I've attemped to use Envoy as my API gateway, and can not seem to get past the above error. Basically I have two .Net 5 services, tags and docs, inside individual docker containers with their ports exposed. I would like to use Envoy as a simple API gateway (no https yet) just to redirect traffic to the proper service based on a simple route match.
Now, I've been using a number of online examples as the basis for my experiment, so I have had to gone wrong somewhere. Any drection pointing would be greatly appreciated. I have verified all of the following:
curl http://localapp-tags/api/Cats successfully.Sites I've used as reference or ran locally to base my application's config file[s] on:
After Googling for hours (too many sites/links to list), the most concrete suggestion was to increase the connection_timeout from .25s to 30secs, this did not make any difference for me. So while I know there seems to be answers out there (and this may be a duplicate), in fact nothing else solved the problem :(
I've also tried to create a named network inside docker-compose (eg. Front-Proxy example, but this did not work either!)
Again, any other suggestions to look into would be appreciated.
So as you can see, I went through a number of tutorials and baby-steps before I came up with my own docker-compose and envoy config files.
docker-compose.yaml (some parts left out for brevity, also disregard spelling errors as I did a search and replace and may have missed something)

So yeah, I'm a bit stuck here trying to figure out what I missed/botched up (but I could just be code blind after these two weeks). The envoy.yaml file was copied from reference material, so I'm just missing something obvious (and hopefully it is not just an ico issue!).
There are a few errors in the tracelog, including the main one above, but I am not yet able to figure out the issue (or to appreciate/understand the tracelog)! Excerpt:

Full trace log from the above session ... here.
Apologies and thanks in advance for any pointing or suggestions. I can provide any missing reference docs as needed.
Thanks Again!
I'm going to give it a few more days, but I think I discovered the issues ... which appear to be fat-fingers, copy & paste.

Now I will go back and re-enable some of the settings I had previously and maybe attempt the Edge Proxy Settings. At least it is running properly now and I learned a lot.
The best part is the role that SO plays in the process. (This is not sarcasm!) After jumping around for days with different working examples, I of course copied something into my configs that were not correct (guess I need to RTFM more). Posting a SO question makes one re-evaluate all the steps and processes taken and lights a bit of a fire.
Thanks SO!
