I really appreciate your help in trying to help and guide me. Blessings for you. Thanks.

First I want to thank you for your time and intention to help me. Thanks for that.

On the other hand, I share that I am also learning about Docker-Compose, actually I have seen that it is very practical using this system since we can use microservices installed by other people. Example apache and php can come already configured in a centos or ubuntu and I just download the image, actually that is what I am doing. The docker-compose that I generate is based on the code of a person who shared it in Hub-Docker, https://hub.docker.com/r/nuttcorp/uvdesk, there is another person who also shares it https: // hub. docker.com/r/dietermartens/uvdesk, in my case I make adjustments to what I need. However, there is that detail that it does not connect to the Database, but it is only from the browser, because if I use an application to access the database if it enters. So I think it is the connection of PHP with MySQL. Previously in UVDESK they told me that it was likely that the Redis PHP extension was missing, however I did not know how to configure it. I hope someone can help me. Thanks.
