Beginning

There are many approaches to implementing a reuse of a common preset for Docker services for multiple environments, such as production and local environments.

This makes it possible to ensure the highest consistency for different environments with the same code-base. Implementing reuse of docker compose options also makes it easier to manage them.

I found on github a project called serversideup/spin. They took an approach using a feature called Docker overrides, to change some properties of common services for different environments.

After reading through their documentation, I realized that there are a few real-life cases where this project can not implement (or is difficult to archive).

# Based on https://steveholgado.com/nginx-for-nextjs/

# - /var/cache/nginx sets a directory to store the cached assets
# - levels=1:2 sets up a two‑level directory hierarchy as file access speed can be reduced when too many files are in a single directory
# - keys_zone=STATIC:10m defines a shared memory zone for cache keys named “STATIC” and with a size limit of 10MB (which should be more than enough unless you have thousands of files)
# - inactive=7d is the time that items will remain cached without being accessed (7 days), after which they will be removed
# - use_temp_path=off tells NGINX to write files directly to the cache directory and avoid unnecessary copying of data to a temporary storage area first

1. Preparing the server

Install git

sudo apt install git-all

Generate Server's SSH public key

ssh-keygen -t rsa -b 4096 -C "deploy"
cat ~/.ssh/id_rsa.pub
