Could you please guide me - How can I connect my local SQL developer to MY SQL Server running on Docker container.
Check for the "bind"in my.cnf in docker running container, if its says 127.0.0.1 it will not connect from outside , you probably needs to change to 0.0.0.0 and restart the mysql server
I have used this command to run container -> docker run -p 3306:3306 --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:latest
It solved that issue for me.

My provider has "extended" my Plesk with MariaDB. Unfortunately, some things don't work anymore, so I'm looking for a way to install MySQL. That is why I'm looking for a way to install MySQL via Docker.
docker run -p 33060:3306 --name mysql-docker-eMYSQL_ROOT_PASSWORD=XXXX -d mysql
The MySQL server also seems to work - but only locally. But I can't connect from outside. I also tried to disable the firewall, temporarily. It wont work..
Can someone please help me to correctly install a MySQL server with Docker and how I can connect to the database?
Check your docker command carefully, you don't have space before and after -e. The command must be
run -p 33060:3306 --name mysql-docker -e MYSQL_ROOT_PASSWORD=XXXX -d mysql
I checked it worked for me
I am very sorry guys, I found several topics on stackoverflow but none of them solved my issue. I am a docker noob, but all I want to do is connect to my docker mysql database in a docker container created via docker-desktop on windows.
docker run -p 3306:3306 --name blaaa -e MYSQL_ROOT_PASSWORD=password -d mysql
I set up everything with the suggested port mapping, but I cannot connect to the docker container from the host (windows 10) via mysql-workbench or other programs. I read that there are issues and you often cannot connect to the docker host via localhost, but I cannot even figure out what the freakin ip of docker0 or other adapters is (ipconfig does not show anything). docker inspect <id> shows a lot of information, but besides mapping to 0.0.0.0:3306 and other ips that don't work, I cannot really figure out what to do here. the container itself is running fine and I can access the database from inside the container without any issues.
thanks for your help!
/SOLVED
I am sorry for the confusion; I think it was due to the Windows clients (I tried several) that things didn't work out. I finally got it working with HeidiSQL. Don't ask me how or why HeidiSQL finally works; but mysql-workbench generally showed strange behavior on my system, it crashed several times out of the blue. Thanks for your help.
Hey when you don't specify the database name, the container will stop as soon as it created, so specify the database name as environment variable
this is the docker command :
docker run -p <host_machine_port>:3306 --name <container_name> -e MYSQL_ROOT_PASSWORD=<root_password> -e MYSQL_DATABASE=<db_name> -d mysql
in your case :docker run -p 3306:3306 --name blaaa -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE= testDB -d MySQL
And next verify if the container running or not: docker ps
if it shows the container name you specified when you created it, it's running.
next connect to your container : mysql --host=127.0.0.1 --port=3306 -u root -p password
this works
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d -p 3307:3306 mysql
reason explained here -p is an argument
https://github.com/docker-library/mysql/issues/504
The instructions here: https://hub.docker.com/_/mysql indicate to run
$ docker run -it --network some-network --rm mysql mysql -hsome-mysql-container -uexample-user -p
But i have no idea what some-network is? So i run this instead and get and 'unknown MySQL host' error even though some-mysql-container is definitely the name of my container.
$ docker run -it--rm mysql mysql -hsome-mysql-container -uexample-user -p
What am I doing wrong here?
'some-network' refers to a docker-network. You need to create it first. I named it 'mysql-network' to make its purpose a bit more clear:
docker network create mysql-network
Then, start database container:
docker run --network mysql-network --name mysql-db -e MYSQL_ROOT_PASSWORD=mysecretpassword -d mysql
Then, start a the client container to connect to the first one:
docker run -it --network mysql-network --rm mysql mysql -hmysql-db -uroot -p
By adding both containers to the same network, they are able to communicate with each other.
I have installed the maria_db service as a docker component of Acumos. Even if the docker container is running, I am not able to execute the following command:
mysql -h localhost -P 3306 --user=root --password=98dceddd-a364-4f76-abe0-b0dc7283fc7f -e 'SHOW DATABASES;'
because I get the error as error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
However, if I login into the docker container using:
docker exec -it acumos_mariadb_db_service bash
and run the same command, it works.
How can I login to the MySQL server from outside the container without getting any error?
Is docker exposing port 3306 on localhost?
docker run --name some-mariadb -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mariadb:tag -p 3306:3306
Docker containers don't expose ports to the host by default; you need to set them up yourself. In the example above, you're mapping the container's port 3306 to your local machine's 3306.
Details for how to set up container networking are here:
https://docs.docker.com/config/containers/container-networking/
I finally fixed the issue. Problem was the mariadb server runs as a docker image exposing port 3306 and the mariadb client is installed on the same local machine also using port 3306. Change the port mapping like 0.0.0.0:3307->3306/tcp solved the issue.
I am still a beginner with docker, trying to use docker to help in my development prototyping. My environment is Mac using boot2docker, version as below
Client version: 1.3.1
Client API version: 1.15
Go version (client): go1.3.3
Git commit (client): 4e9bbfa
OS/Arch (client): darwin/amd64
Server version: 1.3.2
Server API version: 1.15
Go version (server): go1.3.3
Git commit (server): 39fa2fa
I ran the command as below:
docker run --name mymysql -e MYSQL_ROOT_PASSWORD=mypw -e MYSQL_DATABASE=bullshit -d mysql -p 3306:3306
docker start mymysql
I can see the process running as below:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
22d3f780c270 mysql:5 "/entrypoint.sh -p 3 2 minutes ago Up 2 seconds 3306/tcp mymysql
However I still could not connect to the mysql instance running in the docker. I tried connect to the ip retrieved by :
$ boot2docker ip
The VM's Host only interface IP address is: 192.168.59.103
Please give me a pointer on how to solve this issue, I went through the tutorial but I am not sure what went wrong.
The command you used should give an error. The syntax for docker run is as follow:
Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
You have to submit the options to docker run before specifying the image used (mysql in your case), and if it's the case, the command and possible argument(s) to that command.
Not specifying a command will run the default command in the image.
Before running again the container you should stop and remove the old one:
docker kill mymysql
docker rm mymysql
And, following your example you should run:
docker run --name mymysql -e MYSQL_ROOT_PASSWORD=mypw -e MYSQL_DATABASE=bullshit -p 3306:3306 -d mysql
As you set manually a port mapping from container's port 3306 to the same port of your Boot2docker VM, you should can access to MySQL using the IP of the Boot2docker instance, typically 192.168.59.103, and connecting to port 3306.
