Connecting to https://hub.docker.com/r/matsumotory/docker-ngx_mruby/.

matsumotory/ngx-mruby image on Docker Hub

matsumotory/ngx-mruby image on Docker Hub is an official ngx_mruby docker image. This image supports ONBUILD for below commands.

ONBUILD ADD docker/hook /usr/local/nginx/hook
ONBUILD ADD docker/conf /usr/local/nginx/conf
ONBUILD ADD docker/conf/nginx.conf /usr/local/nginx/conf/nginx.conf

So, you can create docker/ directory which include the nginx config files (docker/conf/) and ngx_mruby hook scripts (docker/hook/) into the same directory as Dockerfile before building Dockerfile.

Simple Example

prepare nginx config and ngx_mruby hook files

• current_dir/Dockerfile

FROM matsumotory/ngx_mruby:master
MAINTAINER matsumotory

• current_dir/docker/conf/nginx.conf

user daemon;
daemon off;
master_process off;
worker_processes 1;
error_log stderr;

events {
    worker_connections 1024;
}

http {
    server {
        listen 80;

        location /mruby-hello {
            mruby_content_handler_code 'Nginx.echo "server ip: #{Nginx::Connection.new.local_ip}: hello ngx_mruby world."';
        }

        location /mruby-test {
            mruby_content_handler /usr/local/nginx/hook/test.rb;
        }

        location / {
            resolver 8.8.8.8;
            mruby_set_code $backend '["blog.matsumoto-r.jp", "hb.matsumoto-r.jp"][rand(2)]';
            proxy_pass http://$backend;
        }
    }
}

• current_dir/docker/hook/test.rb

Nginx.echo "This is test for ngx_mruby"

build and run

cd current_dir/
sudo docker build -t local/docker-ngx_mruby .
sudo docker run -p 80:80 -t local/docker-ngx_mruby

access to ngx_mruby

$ curl http://127.0.0.1/mruby-hello
server ip: 172.17.0.200: hello ngx_mruby world.
$ curl http://127.0.0.1/mruby-test
This is test for ngx_mruby
