Proxy files from AWS S3 using nginx

It would seem that the task of implementing the frontend for AWS on nginx sounds like a typical case for StackOverflow - after all, there can be no problems with proxying files from S3? In fact, it turned out that a ready-made solution is not so easy to find, and this article should correct this situation.
 
 
Proxy files from AWS S3 using nginx  
 

Why is this even necessary?


 
 
File access control by means of nginx is relevant for the concept of IaC (infrastructure as code). All changes related to access will be contributed only in configs that are in the project.
 
If you give files through your nginx, it becomes ...[/h]

The confrontation

 3r33520.
 3r33520. - It is understandable! - exclaimed Peter.
 3r33520.
 3r33520. - I will ask not to interrupt. - strictly said Semyon. - I am with you, Peter, have already talked, you have expressed your version. With you, Gennady, I also talked.
 3r33520.
 3r33520. - I already told you everything. - Gena entered uncertainly. - What else do I need from me?

Algorithm operation protocol ssh

Algorithm operation protocol ssh 
3r3-31. Periodically reading articles on SSH, I noticed that their authors sometimes have no idea how this protocol works. In most cases, they are limited to considering the topic of key generation and the description of options for the main commands. Even experienced system administrators often carry a total nonsense when discussing SSH operation issues, giving out opus in the style: the transmitted data is encrypted with the client's open SSH key, and decrypted with a private one, or: the RSA algorithm is used to encrypt data during transmission.
 
 
I will try to bring some clarity to the ...

Replication from Percona Server for MySQL to PostgreSQL using the pg_chameleon

Replication from Percona Server for MySQL to PostgreSQL using the pg_chameleontool. 3r33556. 3r3-31. 3r3544. Replication is one of the well-known functions that allow you to create an identical copy of a database. It is supported in virtually any relational database management system (RDBMS). The ability to replicate provides significant benefits, especially high availability and load sharing. But what if replication is required between two databases (DB) with different structure, such as MySQL and PostgreSQL? Is it possible to continuously replicate changes from a MySQL database to a PostgreSQL database? The answer to this question is the replication tool. pg_chameleon ...

Devops and Security: An Interview with Seth Vargo and Liz Rice

Devops and Security: An Interview with Seth Vargo and Liz Rice 3r3-3549. 3r3-31. Containers today will not surprise anyone. Surprise the question about the safety of containers. It is especially interesting to ask about colleagues who use containers and microservices in production quite seriously: I often see surprised faces and a puzzled question, saying, “What, why is it?” It turns out that we already know about technology (and how not to know here: it seems that soon even schoolchildren will build a Kubernetes cluster in technology classes), but they have not yet learned how to protect its component parts. Perhaps there was simply no one to teach. 3r? ...
