问题
I want to serve a flask app that uses embedded bokeh serve from a server on my local network. To illustrate I made an example using the bokeh serve example and a docker image to replicate the server. The docker image runs Nginx and Gunicorn. I think there is a problem with my nginx configuration routing the requests to the /bkapp uri.
I have detailed the problem and provided all source code in the following git repo
I have started a discussion on bokeh google group
Single Container
In order to reduce the complexity of running nginx in its own container I built this image that runs nginx in same container as the web app
Installation
NOTE: I am using Docker version 17.09.0-ce
Download or clone repo and navigate to this directory (single_container).
# as root
docker build -f Dockerfile -t single_container .
build
start a terminal session in new container
# as root
docker run -ti single_container:latest
In new container start nginx
nginx
now start gunicorn
gunicorn -w 1 -b :8000 flask_gunicorn_embed:app
start
in a separate terminal (on host machine) find the IP address of the single_container container you are running
#as root
docker ps
# then do copy CONTAINER ID and inspect it
docker inspect [CONTIANER ID] | grep IPAddress
find
PROBLEM
Using IP found above (with container running) check out in firefox with inspector. As you can in screenshot above (see screenshots folder "single_container_broken.png" for raw the get request just hangs
broke_1
I can verify that nginx is serving the static files though by navigating to /bkapp/static/ (see bokeh_recipe/single_container/nginx/bokeh_app.conf for config)
static
Another oddidy is that I try to hit the embedded bokeh server directly (with /bkapp/) but i end up with a 400 (denied?)
bkapp
Note about app
- to reduce complexity of dynamically assigning available ports to tornado workers I hard coded in 46518 for port to talk to bokeh serve
nginx config
I know you could just look at bokeh_recipe/single_container/nginx/bokeh_app.conf but I want to show it here. I think I need to config nginx to make explicit that the "request" to bkapp to the 127.0.0.1:46518 is originating FROM the server not the client.
## Define the parameters for a specific virtual host/server
server {
# define what port to listen on
listen 80;
# Define the specified charset to the “Content-Type” response header field
charset utf-8;
# Configure NGINX to deliver static content from the specified folder
# NOTE this should be a docker volume shared from the bokehrecipe_web container (css, js for bokeh serve)
location /bkapp/static/ {
alias /home/flask/app/web/static/;
autoindex on;
}
# Configure NGINX to reverse proxy HTTP requests to the upstream server (Gunicorn (WSGI server))
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host:$server_port;
proxy_buffering off;
}
# deal with the http://127.0.0.1/bkapp/autoload.js (note hard coded port for now)
location /bkapp/ {
proxy_pass http://127.0.0.1:46518;
}
}
