Given your NginX server is expecting connection on unix socket unix:///var/shared/app.sock
This docker image recipe will run small Sinatra
dummy application that will run Puma server on this socket.
For example:
/etc/nginx/nginx.conf
# ...
upstream myapp {
server unix:///var/shared/app.sock;
}
# ...
docker pull equivalent/dummy-sinatra-puma-socket-docker-app
# Run Docker image
mkdir -p /tmp/dummy-app
docker run -v /tmp/dummy-app/:/var/shared/ -d equivalent/dummy-sinatra-puma-socket-docker-app
# Check
docker psNow you have a Puma running on a socket /tmp/dummy-app/app.sock
git clone git@github.com:equivalent/dummy-sinatra-puma-socket-docker-app.git
cd ./dummy-sinatra-puma-socket-docker-app
# build docker image
docker build -t=dummy-sinatra-puma-socket-docker-app .
# Prepare and run Docker image
mkdir -p /tmp/dummy-app
docker run -v /tmp/dummy-app/:/var/shared/ -d dummy-sinatra-puma-socket-docker-app
# Check
docker psTo launch server
git clone git@github.com:equivalent/dummy-sinatra-puma-socket-docker-app.git
cd ./dummy-sinatra-puma-socket-docker-app
bundle install
bundle exec puma config.ru -C puma.rbNow you have a puma running on a socket /tmp/dummy-app/app.sock
Create & start NginX that is expecting connection on socket /tmp/dummy-app/app.sock
for example:
/etc/nginx/nginx.conf
# ...
upstream myapp {
server unix:///tmp/dummy-app/app.sock;
}
# ...
or build a Docker NginX image using your config
/etc/nginx/nginx.conf
# ...
upstream myapp {
server unix:///var/shared/app.sock;
}
# ...
server {
# ...
location / {
# ...
proxy_pass http://myapp;
# ...
}
}
cd ./your-nginx-docker-project
docker build -t=testnginx .
docker run -v /tmp/dummy-app/:/var/shared/ -p 80:80 -it testnginx
if you are getting 504 you may be running nginx before Puma server
- This is a demo app. Be sure to fork and alter any config according to your needs
