@Queryly_twitter you can try removing and adding back, but this may drop connections
Btw, why not just use json or text discovery?
@illarion I will read up on discovery as I am not very familiar with it yet. My goal is have a more flexible way to route traffics based on some business logic (so REST API sounds very appealing to me). I think removing and adding back sounds like a plausible solution as dropping stateless HTTP connections for a few seconds is acceptable.
Illarion Kovalchuk
Discovery is the source of list of backends, there are powerful things such as docker and consul discovery and flexible json and txt for whatever you can imagine
Gb queries selected discovery methid periodically and modifies list of backends
You can even have exec discovery
Really flexible thing
And healthcheck lets you mark backends live and dead temporarily depending on their availability
@illarion Cool. Thanks for the tip. I will read up on it. I am also learning Go. I really like Gb and hope to be able to contribute to some code in future :-)
Illarion Kovalchuk
There is a plenty of issues, you can try your skills on any of them :)
@illarion I notice a few times that the gobetween console seems freeze and wouldn't quite with Control + C. If I close the console by closing the command prompt window, the ports are not released. I would have to reboot the server to restart gobetween again. I haven't been familiar with Golang to dig into the code yet. You probably have already done so, but just want to check in to see if there is away to close connections before the application shutdown/crash.
@illarion Thanks for the tip on discovery. I was able to configure the discovery using JSON to simulate active/passive mode. I run into some issues, but they are mostly Window Server related and I was able to get over them with wrokaround.
@illarion just to correct one thing. I actually wasn't able to shut the gobetween.exe process in task manager. when I ended its the process, an error message say "The operation is not able to completed. access is denied". So there is no way to shut it down without a reboot. No HTTP request is routed after that.
Illarion Kovalchuk
@Queryly_twitter did you make any modifications to gb in order to make it windows service?
Or maybe you simply run it from another user
With higher priveledges
@illarion I simply run it from the command prompt with admin privilege. I didn't modify any code.
Hey guys, anyone who can tell me whether it's possible to do a) TLS termination b) based on the SNI header route one part of the traffic (TCP) to a given backend c) when the SNI doesn't match anything, treat it as HTTP traffic and do "regular" path based routing?
I'm currently investigating several solutions for doing this - Traefik only does L7, HaProxy can do it, but there is no dynamic backend configuration - docker flow proxy seems a viable candidate, except it can't create the tcp/http mix out of the box which I described.. so I just ran into your tool this afternoon, which seems promising, but before I start fiddling again - I was hoping someone might just be able to tell me whether it's possible or not.
OK - never mind either way, just discovered that Docker Swarm doesn't work either :) I'll check back on this in a few months .. back to Docker Flow Proxy I guess.

you can add something like :

hostname_matching_strategy = "regexp"
unexpected_hostname_strategy = "default"

in . sni server section

I'd like to run gobetween in AWS ECS. But having hard time figuring how to pass it a default configuration. CloudWatch logs show:

gobetween v0.5.0
open /etc/gobetween/conf/gobetween.toml: no such file or directory

I see some volume options in ECS container definition, but not seeing how I would get a config file there to map to the /etc/gobetween/conf

I saw we can tell gobetween to use URL for config file, but the Dockerfile in GitHub specifically calls command options for hardcoded path.

CMD ["/usr/bin/gobetween", "-c", "/etc/gobetween/conf/gobetween.toml"]

So when attempting to pass env variables via ECS, we get a different error

gobetween v0.5.0
Passed GOBETWEEN env var and command-line arguments: only one allowed

Would it be possible to publish a different Dockerfile tag on yyyar's account for a more ECS friendly version, like with no static file configuration passed, so we can use the environment variable approach? Or any other ideas?

Andrew Stanton

Okay, I figured out the way to do this in ECS Fargate.... I'm sure there are multiple paths to doing it without requiring any work from Gobetween team. But, the way I was able to do it was to override Dockerfile CMD by defining entryPoint in the container definition which I am sure would be easy for anyone with Docker experience to think of (this is my day 2 of exploring Docker and mostly through the lens of ECS):

"containerDefinitions": [
"entryPoint": [
"environment": [
"name": "GOBETWEEN",
"value": "[\"from-url\", \"http://some.url/gobetween.toml", \"-f\", \"toml\"]"

thank you, we will update the doc

gobetween now on Telegram! Announcing our official Telegram group here: https://t.me/joinchat/GdlUlg_gRfchk1BORU82PA Join now! :-)

Also, to support gobetween please submit your use case here yyyar/gobetween#161 :-) Thank you so much!
hello, I try gobetween v0.6.0. tcp loadbalance roundrobin mode not work.

protocol = "tcp"
bind = ""
balance = "roundrobin"

max_connections = 10000
client_idle_timeout = "10m"
backend_idle_timeout = "10m"
backend_connection_timeout = "2s"

kind = "static"
static_list = [
" weight=1",
" weight=1"

fails = 1
passes = 1
interval = "1s"
kind = "ping"
ping_timeout_duration = "500ms"

I expect 4000,2000 next round 4000,2000 again and again. but not working as expected.
Can I use gobetween instead of haproxy?
My test like this.
simple http backend.
Illarion Kovalchuk
@krast yes. I confirm the bug. Will be fixed soon in 0.6.1

I see you have FreeBSD binary available, but I'd like to build from sources and include in FreeBSD ports tree. I tried some minor modifications but failed to get it working.
if you're able to help further I will open an issue on github to discuss

updating the docker/docker dependency in vendors just caused an explosion of go errors

I managed to build it for freebsd
just set cgo_enabled to 0, like this:
"freebsd 386 0 " "freebsd amd64 0 "
Dave Cottlehuber
illarion: I still get this (on master branch BTW)

is it possible you've different stuff in vendor ?

I cleaned vendor
make clean
make deps
