Improve Docker image & deployment

[kleisauke]

Things that should be done, in no order:

• Create an organization on Docker Hub.
  Done: https://hub.docker.com/u/weserv.
• Copy the contents of this repository to the container instead of defining /var/www/imagesweserv as volume.
  • Perhaps we could just clone the repo (?). For example:

  RUN git clone https://github.com/weserv/images.git /var/www/imagesweserv
  

• Copy /config/nginx/conf.d to /usr/local/openresty/nginx/conf/conf.d/ instead of defining that directory as volume.
• Add RUN make dev to the Dockerfile to install the required LuaRocks dependencies.
• Remove the heavy-weight supervisord approach and set the Docker entrypoint to:

  ENTRYPOINT ["nginx", "-g", "daemon off;"]
  

  • This implies that Redis rate limiter is disabled in the Docker file. Is this the right solution?
• Should we remove /dev/shm as a volume?
• Publish the revamped Docker image to GitHub's Container Registry.
• Test the image on the Google Cloud Platform. See: Deploying the Docker image on Google Cloud Platform #179.

If someone knows more tasks, please feel free to add them in the comments.

• Double-check if the Docker image works out-of-the-box, see Docker: init_by_lua:3: module 'vips' not found #182 .

#204 is part of the work on the Docker deployment.

I know a number of people running the Docker image on Google Cloud Platform without any issues, I'll close.
