I am trying to use the available mysql tags from this doc.
I am using the following command to download the image
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag
But when I run this image with
sudo docker run mysql:tag
it gives the following error
error: database is uninitialized and MYSQL_ROOT_PASSWORD not set
Did you forget to add -e MYSQL_ROOT_PASSWORD=... ?
Any idea on where else to set this password?

I want to run and open a mysql Cli in docker just with one command . Something like this is not working:
docker run --rm -it -p 33060:3306 --name mydb -e MYSQL_ROOT_PASSWORD=secret mysql mysql -p
I know I can connect to mysql after running my container this way
docker -it docker exec -it mydb mysql -p
but i want to do it in one liner.
Thanks

Seems that you can do it in version 8 calling MySQLsh at the end of the command. But unable to do it for previous versions
docker run --name=mk-mysql -p3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -it mysql/mysql-server:8.0.20 mysqlsh
The database server and client are two separate programs. A container only runs one program, so you can't run both the server and the client in the same container, both as the main process. You could write a script that starts the container and then runs mysql to connect to it, but that's about the best you can do.
#!/bin/sh
docker run -d -p 33060:3306 --name mydb -e MYSQL_ROOT_PASSWORD=secret mysql
exec mysql --host=127.0.0.1 --port=33060 --connect-timeout=60 --wait --password
If you're trying to do this to create a database or do other first-time initialization, you can bind-mount an initialization script into /docker-entrypoint-initdb.d and it will run as part of the database setup (only the very first time the database is started).
# Create the storage for the database
# (delete and recreate to rerun the init script)
docker volume create mysql-data
docker run \
-v mysql-data:/var/lib/mysql \
-v $PWD/init.sql:/docker-entrypoint-initdb.d/init.sql \
... \
mysql
If you're just trying to experiment with SQL commands, a serverless database like SQLite might fit your needs better.
the -p parameter is for the ports to be published and should not be part of the -it interactive, that should be your error,
Have a read of the docker run command, in the docker documentation,
https://docs.docker.com/engine/reference/run/
I'm trying to create a simple mysql container, but I'm getting an error.
I created a Dockerfile:
FROM mysql
ENV MYSQL_ROOT_PASSWORD <password>
I built the image:
docker build -t mysql-image -f api/db/Dockerfile .
But when I tried to create a container with a host volume, an error appears:
docker run -d -v $(pwd)/api/db/data:/var/lib/mysql --rm --name mysql-container mysql-image
docker: Error response from daemon: pull access denied for de, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
If I run the same command, but without the volume parameters, then the container is created without any errors:
docker run -d --rm --name mysql-container mysql-image
I appreciate any help
Do you have whitespace in your current path? If so, it may be confusing the $(pwd) as two or more separate parameters. Try wrapping the whole parameter to -v in double quotes.
docker run -d -v "$(pwd)/api/db/data:/var/lib/mysql" --rm --name mysql-container mysql-image
I'm trying to create a container using a volume that I have already created, but my console shows the error
docker container run" requires at least 1 argument
This is the command I'm trying to run:
docker container run --name db -v volume-dados-do-banco:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Mypass
I have also tried this one, wih more arguments, but the same error persists:
docker container run -d --name db -p 3306:3306 -e 'ACCEPT_EULA=Y' -e MYSQL_ROOT_PASSWORD=Mypass -v volume-dados-do-banco:/var/lib/mysql
Any thoughts on the reason why this is happening?
Problem is not with docker, you just didn't specify which image to run. Your command should include Docker image as per documentation.
docker run [OPTIONS] IMAGE[:TAG|#DIGEST] [COMMAND] [ARG...]
Example would be:
docker run -d --name db -v volume-dados-do-banco:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Mypass mysql:latest
i just had the same problem with psql my password simply contained & and i needed to escape it with / before &
try the below command.. it seems a syntax error on your command..
docker container run -d --name db -v volume-dados-do-banco:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Mypass
i have the same problem when i use this:
docker run -d -p 3306:3306 -v /Volumes/wd4black/mysql -e MYSQL_ROOT_PASSWORD=root mysql
but when i try below, the problem is disappear:
docker run --name my-s -d -p 3306:3306 -v /Volumes/wd4black/mysql -e MYSQL_ROOT_PASSWORD=root mysql
so i think the --name is key, but the doc didn/t write it.
I just restarted docker and ran:
docker run --name torgmysqldb --volumes-from volume-dados-banco-mysql -e MYSQL_ROOT_PASSWORD=Mypass -p 3307:3306 mysql
I found out a known issue about this:
https://github.com/docker/for-win/issues/2722
After you have extracted the image from the Docker repository, you can move on to deploying the new Container with the following code snippet:
sudo docker run --name=[container_name] -d [image_tag_name]
I'm trying to link two containers together, I was able to connect a PhpMyAdmin container with a MySQL container, but nothing seem to work when I'm using a WordPress container.
I tried different things, actually I'm using this command to run a MySQL container:
sudo docker run --name sql -e MYSQL_ROOT_PASSWORD=pass mysql
and this one to set up the WordPress container:
sudo docker run --name wpress -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=pass -e WORDPRESS_DB_HOST=172.17.0.2 -p 8085:80 --link sql:mysql wordpress
MySQL container work fine, but I have this output from wpress:
MySQL Connection Error: (2054) The server requested authentication method unknown to the client
Warning: mysqli::__construct(): The server requested authentication method unknown to the client [caching_sha2_password] in Standard input code on line 22
What I am doing wrong?
Edit:
I was able to connect the wpress container to sql container a couple of time during some test by adding a port to WORDPRESS_DB_HOST, which will give:
sudo docker run --name wpress -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=pass -e WORDPRESS_DB_HOST=172.17.0.2:3306 -p 8085:80 wordpress
(I also remove the --link option, it worked without it).
So it work 2-3 times, but it doesn't work anymore.
It seem to be a version error. Use an image with a different version of mysql, mysql:5.7 for example, and it should work.
I had same problem/error.
This is what I had to do for mysql and wordpress:
docker run --name wordpressdb -e MYSQL_ROOT_PASSWORD=password -d mysql
docker exec -it wordpressdb bash
#inside run:
mysql -uroot -ppassword
#paste
ALTER USER 'root'#'%' IDENTIFIED WITH mysql_native_password BY 'password';
exit
exit
docker run --name wordpress -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=password -p 8080:80 --link wordpressdb:mysql -d wordpress
I have a usecase where i need to run mysql on a container and link it to another container. I also have my db files data in my host location which is mounted as a volume on to the database container... The condition is to run the container not as root but as a different user with all privileges.
The db is there is in the mounted volume.
I ran the following command:
docker run -d -v ~/testdata:/var/lib/mysql -e MYSQL_DATABASE=Testdata_DB -e MYSQL_USER=testdata -e MYSQL_PASSWORD=mypasswordhere -p 3306:3306 --name=testdata_db mysql
The above command will start the container but i am not able to see the user with the password when i bash into the running container. Only the mysql is running
docker exec -it testdata_db bash
Kindly let me know where i am going wrong. I followed the documentation under the docker official repo link.
I solved it by creating a init.sql with the required sql commands to create user , tables which it loaded from my host to the container under docker-entrypoint-initdb.d/ and set the env varibles as required. This made mysql instance load as a fresh instance and loaded all the required tables and data.
The final command is:
docker run --name testdata_db -p 3306:3306 -e "MYSQL_ROOT_PASSWORD= " -e "MYSQL_USER=test" -e "MYSQL_PASSWORD=mypass" -e "MYSQL_DATABASE=mysql" -v ~/mysql/db/:/var/lib/mysql/ -v ~/mysql/init/:/docker-entrypoint-initdb.d/ -d mysql
