Hello,
I am facing issues with running Jupyter notebook behind relayd. This is
most probably because of websockets proxy.
When I open a notebook, its not able to connect to the kernel.
Searching on the net pointed me to this issue -
https://github.com/jupyter/notebook/issues/2664
The solution there is with an nginx configuration. I am not able to figure
out equivalent relayd config.
Any help here would be appreciated.
Here is my relayd config -
-
-
relayd_addr="0.0.0.0"
relayd_port="80"
jupyter_port="5000"
table { 127.0.0.1 }
httpd_port="8000"
table { 127.0.0.1 }
log all
http protocol "httpfilter" {
match header append "X-Forwarded-For" \
value "$REMOTE_ADDR"
match header append "X-Forwarded-By" \
value "$REMOTE_ADDR:$SERVER_PORT"
match header set "Keep-Alive" value "$TIMEOUT"
### TCP performance options
tcp { nodelay, sack, socket buffer 65536, backlog 100 }
### Return HTTP/HTML error pages
return error
match request path "/ipython/*" forward to
match request path "/" forward to
}
relay http {
listen on $relayd_addr port $relayd_port
protocol "httpfilter"
forward to port $jupyter_port mode loadbalance
forward to port $httpd_port check tcp interval 60
}

Regards.
