KiwiTCMS - MySQL DB with mysql_native_password encryption method - kiwi-tcms

Question

Setup
kiwi - latest
mysql -latest (v8.0.21)
os - mac
I have change the docker-compose.yml as below, and it can start-up the two containers.
services:
db:
container_name: kiwi_db
image: mysql:latest
volumes:
- db_data:/var/lib/kiwi_mysql/data
# workaround for missing charset & collation support
# https://github.com/sclorg/mariadb-container/pull/125
- ./99-charset.sh:/usr/share/container-scripts/mysql/init/99-charset.sh:Z
- ./99-charset.cnf:/usr/share/container-scripts/mysql/cnf/99-charset.cnf:Z
restart: always
environment:
MYSQL_ROOT_PASSWORD: kiwi-1s-aw3s0m3
MYSQL_DATABASE: kiwi
MYSQL_USER: kiwi
MYSQL_PASSWORD: kiwi
MYSQL_CHARSET: utf8mb4
MYSQL_COLLATION: utf8mb4_unicode_ci
web:
container_name: kiwi_web

- db
restart: always
image: kiwitcms/kiwi:latest
ports:

When I execute docker exec -it kiwi_web /Kiwi/manage.py migrate, it will get some error message.
I am trying to change the encryption method of user password from caching_ sha2_ Password to mysql_native_password, but it still pop up the same error message.
Traceback of the error:

Answer 1

You are trying to use the official MySQL docker images with a docker-compose.yml configuration for the CentOS MariaDB image which Kiwi TCMS uses by default.
A quick look at MySQL's container image at https://hub.docker.com/_/mysql tells me it doesn't support some of the environment variables used in the MariaDB image.
The error which I see is caused by trying to use the mariadb client library (to make the connection) which seems incompatible with MySQL. And I think there are quite a few incompatibilities between MariaDB and MySQL latest versions these days.
So you need to do 2 things:
Figure out how to properly configure the MySQL container via environment variables as per their documentation
Figure out if the MariaDB client libraries will work with a MySQL server (or not).
Also see https://docs.djangoproject.com/en/3.0/ref/databases/#mariadb-notes for references.
For 2) you can open an issue on GitHub so we don't forget to add it to our test suite. IDK at the top of my head what is the state of mysql/mariadb libraries lately and if they can be installed and used side-by-side or if they will conflict with each other.
