mailcatcher | Debugging app for PHP sendmail

I am desperate with a task.

I bassicly tried everything and can't get to solution.

I am trying to send mail with Swiftmailer asynchronously by using the SymMessenger, AMQP, rabbitmq with docker.

Everything is is installed, but within API platform I always get an error I could not handle.

The idea is to trigger __invoke function on persisting MyEntity entity. I tried with mailcatcher, everything is working so I tried with async examples.

"Attempted to load class "AMQPConnection" from the global namespace.\nDid you forget a "use" statement for "PhpAmqpLib\Connection\AMQPConnection"?",",

I configured parameters starting with docker-compose.yml file

I have Rails application running in Docker, and I want to integrate mailcatcher for development.

docker-compose.yml

I have this file "docker-compose.yml"

I tried to follow this tutorial by GoRails to add EasyAutoComplete to my Rails app: https://www.youtube.com/watch?v=ibxlNN73UTY

Although the search bar functions as the GoRails guy demonstrates, I keep seeing this page whenever I click on any link:

If I refresh this page, then it takes me to the user sign in page that I originally clicked on. I don't notice anything out of the ordinary in my Rails server console throughout this process.

I added the css files and the js files for EasyAutoComplete to my Assets pipeline, because I was having a hard time using webpacker correctly.

For jquery, I followed this article to install it: https://www.botreetechnologies.com/blog/introducing-jquery-in-rails-6-using-webpacker and I used this video as reference as well: https://www.youtube.com/watch?v=bn9arlhfaXc

My Gemfile looks like:

This is a continuation of my journey of creating multiple docker projects dynamically. I did not mention previously, to make this process dynamica as I want devs to specify what project they want to use, I'm using ansible to up local env.

Logic is:

1. running ansible-playbook run.yml -e "{projectsList: ['app-admin']}" - providing list of projects I want to start
2. stop existing main containers (in case they are running from the previous time)
3. Start the main containers
4. Depend on the provided list of projects run role tasks () I have a separate role for each supported project
5. stop the existing child project containers (in case they are running from the previous time)
6. start the child project containers
7. make some configuration depend on the role

And here is the issue (again) with the network, when I stop the main containers it's failing with a message:

error while removing network: network appnetwork has active endpoints

it makes sense as child docker containers use the same network, but I do not see so far way to change ordering of tasks as I'm using the roles, so main docker tasks always running before role-specific tasks.

main ansible file:

I have tried everything and nothing seems to be working. could one kindly advise how i can rectify this issue

error message:

My ActionMailer adds a carrige return to the end of every line:

I'm relatively new to Ruby and Rails, been teaching myself in free time. I recently added a few gems to my gemfile, and now my scaffold is giving me errors--couldn't find another answer on StackOverflow that addressed my issue (apologies in advance if my search prowess isn't up to par).

Gemfile:

I try to start mailcatcher. And I got error: something's use port 1025. Are you already running MailCatcher?

I try this, and similar answers, but, when I execute lsof command, there is nothing in result for this command which use this port, result of lsof command is EMPTY.

Any idea? (I can't reach the 127.0.0.0:1080 or similar, and my command to start mailcatcher is $ mailcatcher -ip=0.0.0.0)

Thank you in advance.
