Access denied for user 'root'@'localhost' with mariadb 10.4.8 docker container using docker compose and issue while attaching external volume

Question

I am new to Docker, I was trying to crate docker container of mariadb for my application but when I start running mariadb container it shows Access denied for user 'root'@'localhost' (using password: YES) dockerfile

Following is the docker compose I am using.

version: '3'

services:
  mysql:
    image: mariadb
    container_name: mariadb
    volumes:
      - dbvolume:/var/lib/mysql
      - ./AppDatabase.sql:/docker-entrypoint-initdb.d/AppDatabase.sql
    environment:
      MYSQL_ROOT_PASSWORD: root123
      MYSQL_ROOT_USER: root
      MYSQL_USER: root
      MYSQL_PASSWORD: root123
      MYSQL_DATABASE: appdata
    ports:
      - "3333:3306"

volumes:
  dbvolume:

After trying for multiple times by referring few links I was able to connect my application to docker container but it failed to import AppDatabase.sql script at the time of creating docker container.

But now by using same docker compose file I am not able to connect mariadb to my application and I think even it's not importing SQL script to the database (based on logs I have observed).

Following is the docker log generated while running docker compose:

SQL Script I am trying to import:

create database appdata;
use appdata;

CREATE TABLE `appdatadetails` (
  `Name` varchar(8) NOT NULL,
  `appIndex` int(11) NOT NULL,
  `connector` varchar(16) DEFAULT NULL,
  `intName` varchar(12) DEFAULT NULL,
  `intIndex` int(11) DEFAULT NULL,
  PRIMARY KEY (`Name`,`appIndex`)
) 

Please help me to understand what I am doing wrong, I have tried all possible solution posted on different blogs.

Latest Update:

I was able to up and running mariadb docker image with 10.1. But if I attach volume then still I am facing issue.

Docker Compose:

version: '3'

services:
  mysql:
    image: mariadb:10.1
    container_name: mariadb
    volumes:
      - container-volume:/var/lib/mysql
      - ./AppDatabase.sql:/docker-entrypoint-initdb.d/AppDatabase.sql
    environment:
      MYSQL_ROOT_PASSWORD: root123
      MYSQL_DATABASE: appdata
    ports:
      - "3333:3306"

volumes:
  container-volume:

And the log error message, If I attach container-volume volume.

If I remove container-volume then It is importing .sql script and running well and good.

Updated with working script: Before I was using mariadb 10.4.8 or latest and facing issue(s) to access DB and attaching external volume.

Now I have downgraded (As suggested by @Adiii) and tried. It runs perfectlly and we no need to specify external: true in volumes service

version: '3'

services:
  mysql:
    image: mariadb:10.1
    container_name: mariadb
    volumes:
      - ./dbvolume:/var/lib/mysql
      - ./AppDatabase.sql:/docker-entrypoint-initdb.d/AppDatabase.sql
    environment:
      MYSQL_ROOT_PASSWORD: root123
      MYSQL_DATABASE: appdata
    ports:
      - "3333:3306"

Solution

It will affect the new user and keys even if you create fresh container.

Remove mount location, as it will pick a user name and password from this location, also will not run your DB init script too.

    volumes:
      - dbvolume:/var/lib/mysql

Also you do not need

create database appdata;

As database already created at

      MYSQL_ROOT_PASSWORD: root123
      MYSQL_ROOT_USER: root
      MYSQL_DATABASE: appdata

this step.

update:

remove the user root, as root already defined. you can try with

version: '3.7'
services:

  mysql:
    environment:
      MYSQL_ROOT_PASSWORD: root123
      MYSQL_DATABASE: appdata
    image: mariadb

Or the second user should be different

version: '3.7'

services:

  mysql:
    environment:
      MYSQL_ROOT_PASSWORD: root123
      MYSQL_DATABASE: appdata
      MYSQL_USER: test
      MYSQL_PASSWORD: root123
    image: mariadb

you can try with

docker exec -it container_name bash -c "mysql -u test -proot123"

or

docker exec -it mysql bash -c "mysql -u root -proot123"

If still issue, remove the DB image, pull a new one.

Or try image tag 10.1

If I remove container-volume then It is importing .sql script and running well and good.

if mount the location then the init script will not run as the container is expecting that there is already DB or try to remove named volume and create new one.

So mount the location, import the DB using MySQL command and use the mount location for next time.

Thanks for your replay, but still I am not able to access mariadb container. I am keep getting ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

[Adiii]

against which user you are trying to login? try to debug docker exec -it mysql bash -c "mysql -u root -proot"

[Rajesh Hatwar]

I have updated my post with screen shot, I have created a folder and crated docker compose yml file and executed docker-compose up and tried to access the container but it didn't help. I have used your second your script.

[Adiii]

Try to remove and i tested it, did you run thy debug script

[Adiii]

using password yes is very clear, something wrong the with password. you can try provided both example. one should work

[Rajesh Hatwar]

I have tried by pulling different image but problem still persist. One thing I have oberved is, if I run docker exec -it mariadb bash -c "mysql -u test" without password it's going inside the DB!. But with password it is showing Access denied for user 'test'@'localhost' (using password: YES)

[Adiii]

Let us continue this discussion in chat.

[Adiii]

try to run with docker run command, seems like ENV not setting, docker run --name some-mariadb -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mariadb:latest
