I am try to run a mysql container and connect with mysql client then:
I've used following commands:
docker run --name=mysql -d mysql/mysql-server:latest
docker exec -it mysql mysql -uroot -p
According to tutorial, the last command allow me configure database password but When I introduce the first password it fails...
The first password was root and I get an unusual error, then I try with admin, admin an even my linux user password but They don't work...
I would like to know what's the error?
Logging into the MySQL Server You will be prompted for the root user's password. Use the password revealed by the docker logs mysql01 command. Once within the MySQL server, you can then change the password with the command: ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';
The default user for MySQL is root and by default it has no password. If you set a password for MySQL and you can't recall it, you can always reset it and choose another one.
By default, “0” denotes root user. You can also choose to specify, simply as “root”. I always find the above command handy in most situations to execute on a running container.
Here are the steps you can follow to install the Dockerhub MySQL Container: Step 1: Pull the Docker Image for MySQL. Step 2: Deploy and Start the MySQL Container. Step 3: Connect with the Docker MySQL Container.
There are couple of ways to see the password. First Approach - Don't Run container in daemon mode
Check the below command
docker run --name=mysql mysql/mysql-server:latest
and this will print the password in the terminal as look at the below logs

Second Approach - Run container in daemon mode & fetch the password from logs Check the below command to run the container
docker run -d --name=mysql mysql/mysql-server:latest
and then run the below command to fetch the password
docker logs mysql 2>&1 | grep GENERATED
Output of above command is:
[Entrypoint] GENERATED ROOT PASSWORD: PopiKQIjAS#OGj3x]yJOBLEn80p
Once you have the password by one of the above-mentioned methods, you can then login with the below command using that password
docker exec -it mysql mysql -uroot -p
When asked, enter the generated root password (see the instructions above on how to find it). Because the MYSQL_ONETIME_PASSWORD
option is true by default, after you have connected a mysql client to the server, you must reset the server root password by issuing this statement:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password';
Substitute password
with the password of your choice. Once the password is reset, the server is ready for use.
Ref: https://hub.docker.com/r/mysql/mysql-server/
docker inspect <container_name_here>
command output shows root password among other params
