I started Kiwi TCMS in Docker (k8s) with Postgresql. It started ok, but when I wanted to run migrations it crashed. I used this docker-compose for inspiration.
Log shows problem with connection with MySQL. But I changed configuration for engine. See:

This is setting an environment variable inside the docker container and I'm not sure if that works or which one takes precendece.
If you want somebody to help you post the entire docker-compose.yml (or whatever kubernetes control file you use). Clearly the application thinks it is configured to talk to MySQL and fails when MySQL isn't available.
So problem was with version of used docker image.
I used docker image tag kiwitcms/kiwi:6.2 and I thought it's the latest release. But it's not. This version(docker image) doesn't have code for changing DB engine. I changed version of docker tag to latest and it works pretty well now.

i dont know why django can't see my db, maybe you guys have some ideas.
Mysql didn't get me any problems before this case,
i haven't found a way to fix an error, so I counting on your help.
thanks in advance
The shortest answer to that is that django database ist't crated in MySQL. Django will not create the database for you like it do on sqlite3, you have to had this database created before.
You can ensure that you created the database by running a command like that:
$ mysql -h 127.0.0.1 -pmypassword -u myusername # to connect on your mysql
mysql> show databases; # list all databases on your MySQL server
To create a new database my recomendation is the following:
mysql> create database django charset utf8mb4; -- charset is optional
mysql> use django;
I have a dockerized django project. I'm trying to make migrations, but I keep getting this error. What does this mean, and how can I fix it? I am really new to this, so please be as detailed as possible! Thank you

Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Your Django application is not connecting to the database.
Couple of things to check.
What port is your database running on and what is the hostname? If you're using docker-compose, the host will be the same as the database service name.
Next, check your settings.py insuring that your database is using the correct host and port. By default, on Postgres, Django will use port 5432. If this is not the case, update it.
Similarly, if you have not explicitly set a host, Django will use localhost. You will need to change this value to whatever your database service name is.
I recently started using sql and connected to an remote sql server. I can run queries on it in python shell and get correct results. However, when I run
manage.py runserver
It tells me that there I need to migrate, however when I migrate I get an error saying:

What should I do to fix this error.

So this is a networking problem in which your application is unable to establish a TCP connection to your database. Maybe because of a lack of configuration on your RDS instance? wrong hostname? wrong port? firewall (as mentioned by #Willem van Onsem)? Maybe the Amazon AWS guide on connecting to their database service helps you
In any case it has nothing to do with your program code, apart from the connection string if its wrong.

Since I should have magically known your settings.py DB config and my post was deleted for not answering the question without "requiring clarification from the asker" I'm reposting to try and help. The default password for root user in a mysql db is "", that is its left blank. Right now there is a mismatch between your db and the configuration you provided in your settings.py file. Go into your dbms and make sure that the setting for the database match the ones you provided in your settings.py.
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB NAME',
'USER': 'USER NAME',
'PASSWORD':'USER PW',
'HOST' : 'localhost',
}
}
If these match to your db you should be able to now migrate.

I am trying to complete the Ultimate Django tutorial: https://ultimatedjango.com/learn-django/lessons/handling-sensitive-keys/?trim=yes
On the section of sensitive keys it gives me the following errors when I run the server with : python manage.py runserver
CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.
Then on the settings.py i put :
ALLOWED_HOSTS = ['*']
and when I run the server again gives the following error:
Performing system checks...
System check identified no issues (0 silenced).
