A Rate-Limiting HTTP Proxy(7)Docker and Deployment

We plan to use sudo to run the command to start the nginx on port 80, we need to link the command first
>sudo ln -s /opt/openresty/nginx/sbin/nginx /usr/local/sbin/nginx

On MAC it works well, on RaspberryPI, it has this exception while running it
>sudo nginx -p /opt/luaweb/dist/app -c conf/nginx.conf
nginx: [emerg] getgrnam("owner") failed in /opt/luaweb/dist/app/conf/nginx.conf:1

Solution:
I change the nginx.conf and get rid of owner, it works.

After install the things, the URL for luarocks is as follow:
/tool/luarocks/lib/luarocks/rocks

The Makefile will build the binary and prepare the ENV.
IMAGE=sillycat/public
TAG=raspberrypi-openresty
NAME=raspberrypi-openresty

app-init:
rm -fr install
mkdir install
wget https://openresty.org/download/openresty-1.11.2.3.tar.gz -P install/
wget http://luarocks.github.io/luarocks/releases/luarocks-2.4.2.tar.gz -P install/

app-build:
./package.sh
tar -cvzf ./dist/$(NAME)-1.0.tgz ./luaweb-1.0

docker-context:

build: docker-context
docker build -t $(IMAGE):$(TAG) .

run:
docker run -d -p 80:80 --name $(NAME) $(IMAGE):$(TAG)

debug:
docker run -ti -p 80:80 --name $(NAME) $(IMAGE):$(TAG) /bin/bash

clean:
docker stop ${NAME}
docker rm ${NAME}

logs:
docker logs ${NAME}

publish:
docker push ${IMAGE}:${TAG}

fetch:
docker pull ${IMAGE}:${TAG}

And package.sh will help to binary the lua scripts
#!/usr/bin/env bash

rm -rf ./luaweb-1.0
mkdir -p luaweb-1.0/logs
mkdir -p luaweb-1.0/conf
cp -rf conf/nginx-prod.conf luaweb-1.0/conf/nginx.conf
cp -rf html luaweb-1.0
cp -rf lua luaweb-1.0
cp -rf lualib luaweb-1.0

luajit=/opt/openresty/luajit/bin/luajit

function compile() {
    for file in $1
    do
        if test -f $file
        then
            $luajit -b $file $file
        fi
    done
}

compile "./luaweb-1.0/lua/web/*"
compile "./luaweb-1.0/lua/*"

Dockerfile will describe all the steps to set up image
