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 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
(Updated)*****
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/
Im running docker on windows and I start up a docker container with MySql like this
docker run -p 3306:3306 --name test -e MYSQL_ROOT_PASSWORD=secret-pw -d mysql/mysql-server:5.5
Then on my host I start up Mysql workbench and try to connect but it does not work.
docker inspect test reveal IP address on 172.17.0.2 but when I ping this I get no reply
Got this working on a linux host and I am pretty sure I have done the exact same steps
What am I doing wrong ?

/path/to/data/dir: share path between container and host
root_pwd: mysql root password
tag: repository tag
utf8mb4: mysql server character set and collation type

Following steps to connect remotely:
docker exec -it mydb bash --> this will connect to mySql container.
echo "bind-address = 0.0.0.0" >> /etc/mysql/my.cnf --> this will update the my.cnf file.
service mysql restart --> restart the mySql service.
exit --> the mySql container.
docker inspect mysql | grep IPAddress --> grep the IP address of the contaner.
mysql -h 172.17.0.2 -u root –p --> remotely connect to the mySql.
Your host 3306 port should be forwarding to the container, so try connecting on localhost:3306. When I tried to replicate, got the "Host 172.17.0.1 not allowed to connect to this MySQL server" which means it got through at least.
More on the latter: https://github.com/fideloper/docker-mysql/issues/10
I have a mysql container which runs fine. I can start it and see it up and running in the docker ps list.
I then try to run another learnitouch container in which an engine-db-seed.sh shell script tries to connect to the mysql container server.
The learnitouch container Dockerfile contains:
ENTRYPOINT ["/bin/bash", "/usr/bin/learnintouch/engine-db-seed.sh"]
The engine-db-seed.sh file contains:
/usr/bin/mysql/install/bin/mysql --protocol=tcp -h 172.17.0.2 -u root -proot -v < /usr/bin/learnintouch/db_engine-db.sql
The db_engine-db.sql is being seeded all right in the mysql database.
But I had to hard code the mysql container IP as you can see in the -h option. I got the 172.17.0.2 IP address from a docker inspect on the mysql container. Not the most automated way...
How can I do without such hard coding ?
Running the mysql container:
docker run -d -p 3306:3306 -v /home/stephane/dev/php/learnintouch/docker/mysql/data:/usr/bin/mysql/install/data --name mysql stephane/mysql:5.6.30
Running the learnintouch container:
docker run -p 127.0.0.1:80:80 --link mysql:mysql --name learnintouch stephane/learnintouch
I'm using Docker version 1.12.1, build 23cf638
Just use the service name and make sure that both services are running on the same network (bridge0 by default).
So if you create your mysql service like this
docker run -d --name foo mysql-image
your engine-db-seed.sh could then be
/usr/bin/mysql/install/bin/mysql --protocol=tcp -h foo -u root -proot -v < /usr/bin/learnintouch/db_engine-db.sql
mysql will make a dns request for foo which will be resolved by Docker to the ip of your foo service.
In a nutshell
I want to run mysql in a docker container and connect to it from my host. So far, the best I have achieved is:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
More details
I'm using the following Dockerfile:
FROM ubuntu:14.04.3
RUN apt-get update && apt-get install -y mysql-server
# Ensure we won't bind to localhost only
RUN grep -v bind-address /etc/mysql/my.cnf > temp.txt \
&& mv temp.txt /etc/mysql/my.cnf
# It doesn't seem needed since I'll use -p, but it can't hurt
EXPOSE 3306
CMD /etc/init.d/mysql start && tail -F /var/log/mysql.log
In the directory where there is this file, I can succesfully build the image and run it with:
> docker build -t my-image .
> docker run -d -p 12345:3306 my-image
When I attach to the image, it seems to work just fine:
# from the host
> docker exec -it <my_image_name> bash
#inside of the container now
$ mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.
[...]
However I don't have that much success from the host:
> mysql -P 12345 -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Even more details
I've seen that there's a question which looks like mine. However, it isn't the same (and it doesn't have any answers anyway)
I've seen that there are images dedicated to mysql, but I didn't have more success with them
My grep -v may feel weird. Admittedly, there may be cleaner way to do it. But when I attach my image, I can observe it actually worked as expected (ie: removed the bind-address). And I can see in the container /var/log/mysql/error.log:
Server hostname (bind-address): '0.0.0.0'; port: 3306
- '0.0.0.0' resolves to '0.0.0.0';
Server socket created on IP: '0.0.0.0'.
If your Docker MySQL host is running correctly you can connect to it from local machine, but you should specify host, port and protocol like this:
mysql -h localhost -P 3306 --protocol=tcp -u root
Change 3306 to port number you have forwarded from Docker container (in your case it will be 12345).
Because you are running MySQL inside Docker container, socket is not available and you need to connect through TCP. Setting "--protocol" in the mysql command will change that.
If you use "127.0.0.1" instead of localhost mysql will use tcp method and you should be able to connect container with:
mysql -h 127.0.0.1 -P 3306 -u root
I recommend checking out docker-compose. Here's how that would work:
Create a file named, docker-compose.yml that looks like this:
version: '2'
services:
mysql:
image: mariadb:10.1.19
ports:
- 8083:3306
volumes:
- ./mysql:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: wp
Next, run:
$ docker-compose up
Notes:
For latest mariadb image tag see https://hub.docker.com/_/mariadb/
Now, you can access the mysql console thusly:
$ mysql -P 8083 --protocol=tcp -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 5.5.5-10.1.19-MariaDB-1~jessie mariadb.org binary distribution

mysql>
Notes:
You can pass the -d flag to run the mysql/mariadb container in detached/background mode.
The password is "wp" which is defined in the docker-compose.yml file.
Same advice as maniekq but full example with docker-compose.
The simple method is to share the mysql unix socket to host machine. Then connect through the socket
Steps:
Create shared folder for host machine eg: mkdir /host
Run docker container with volume mount option docker run -it -v /host:/shared <mysql image>.
Then change mysql configuration file /etc/my.cnf and change socket entry in the file to socket=/shared/mysql.sock
Restart MySQL service service mysql restart in docker
Finally Connect to MySQL servver from host through the socket mysql -u root --socket=/host/mysql.sock. If password use -p option
OK. I finally solved this problem. Here follows my solution used in https://sqlflow.org/sqlflow.
The Complete Solution
To make the demo self-contained, I moved all necessary code to https://github.com/wangkuiyi/mysql-server-in-docker.
The Key to the Solution
I don't use the official image on DockerHub.com https://hub.docker.com/r/mysql/mysql-server. Instead, I made my own by installing MySQL on Ubuntu 18.04. This approach gives me the chance to start mysqld and bind it to 0.0.0.0 (all IPs).
For details, please refer to these lines in my GitHub repo.
SQLFLOW_MYSQL_HOST=${SQLFLOW_MYSQL_HOST:-0.0.0.0}
echo "Start mysqld ..."
sed -i "s/.*bind-address.*/bind-address = ${SQLFLOW_MYSQL_HOST}/" \
/etc/mysql/mysql.conf.d/mysqld.cnf
service mysql start
To Verify My Solution
Git clone the aforementioned repo.
git clone https://github.com/wangkuiyi/mysql-server-in-docker
cd mysql-server-in-docker
Build the MySQL server Docker image
docker build -t mysql:yi .
Start MySQL server in a container
docker run --rm -d -p 23306:3306 mysql:yi
Install the MySQL client on the host, if not yet. I am running Ubuntu 18.04 on the host (my workstation), so I use apt-get.
sudo apt-get install -y mysql-client
Connect from the host to the MySQL server running in the container.
mysql --host 127.0.0.1 --port 23306 --user root -proot
Connect from Another Container on the Same Host
We can run MySQL client from even another container (on the same host).
docker run --rm -it --net=host mysql/mysql-server mysql \
-h 127.0.0.1 -P 13306 -u root -proot
Connect from Another Host
On my iMac, I install the MySQL client using Homebrew.
brew install mysql-client
export PATH="/usr/local/opt/mysql-client/bin:$PATH"
Then, I can access the above Ubuntu host (192.168.1.22).
mysql -h 192.168.1.22 -P 13306 -u root -proot
Connect from a Container Running on Another Host
I can even run MySQL client in a container running on the iMac to connect to the MySQL server in a container on my Ubuntu workstation.
docker run --rm -it --net=host mysql/mysql-server mysql \
-h 192.168.1.22 -P 13306 -u root -proot
A Special Case
In the case that we run MySQL client and server in separate containers running on the same host -- this could happen when we are setting up a CI, we don't need to build our own MySQL server Docker image. Instead, we can use the --net=container:mysql_server_container_name when we run the client container.
To start the server
docker run --rm -d --name mysql mysql/mysql-server
To start the client
docker run --rm -it --net=container:mysql mysql/mysql-server mysql \
-h 127.0.0.1 -P 3306 -u root -proot
if you running docker under docker-machine?
execute to get ip:
docker-machine ip <machine>
returns the ip for the machine and try connect mysql:
mysql -h<docker-machine-ip>
In your terminal run: docker exec -it container_name /bin/bash
Then: mysql
You should inspect the IP address assigned to the running container, and ther connect to that host:
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container name or id>
than you can connect with:
mysql -h <IP provided by inspect command> -P <port> -u <user> -p <db name>
https://mariadb.com/kb/en/installing-and-using-mariadb-via-docker/#connecting-to-mariadb-from-outside-the-container
I do this by running a temporary docker container against my server so I don't have to worry about what is installed on my host. First, I define what I need (which you should modify for your purposes):
export MYSQL_SERVER_CONTAINER=mysql-db
export MYSQL_ROOT_PASSWORD=pswd
export DB_DOCKER_NETWORK=db-net
export MYSQL_PORT=6604
I always create a new docker network which any other containers will need:
docker network create --driver bridge $DB_DOCKER_NETWORK
Start a mySQL database server:
docker run --detach --name=$MYSQL_SERVER_CONTAINER --net=$DB_DOCKER_NETWORK --env="MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD" -p ${MYSQL_PORT}:3306 mysql
Capture IP address of the new server container
export DBIP="$(docker inspect ${MYSQL_SERVER_CONTAINER} | grep -i 'ipaddress' | grep -oE '((1?[0-9][0-9]?|2[0-4][0-9]|25[0-5])\.){3}(1?[0-9][0-9]?|2[0-4][0-9]|25[0-5])')"
Open a command line interface to the server:
docker run -it -v ${HOST_DATA}:/data --net=$DB_DOCKER_NETWORK --link ${MYSQL_SERVER_CONTAINER}:mysql --rm mysql sh -c "exec mysql -h${DBIP} -uroot -p"
This last container will remove itself when you exit the mySQL interface, while the server will continue running. You can also share a volume between the server and host to make it easier to import data or scripts. Hope this helps!
mysql -u root -P 4406 -h localhost --protocol=tcp -p
Remember to change the user, port and host so that it matches your configurations. The -p flag is required if your database user is configured with a password
docker run -e MYSQL_ROOT_PASSWORD=pass --name sql-db -p 3306:3306 mysql
docker exec -it sql-db bash
mysql -u root -p
For conversion，you can create ~/.my.cnf file in host:
[Mysql]
user=root
password=yourpass
host=127.0.0.1
port=3306
Then next time just run mysql for mysql client to open connection.
run following command to run container
docker run --name db_name -e MYSQL_ROOT_PASSWORD=PASS--publish 8306:3306 db_name
run this command to get mysql db in host machine
mysql -h 127.0.0.1 -P 8306 -uroot -pPASS
in your case it is
mysql -h 127.0.0.1 -P 12345 -uroot -pPASS
First, see the logs Are there any errors or not.
docker ps -a
docker logs container_name
If there is any error, search for the solution of that particular error, if there are no errors you may proceed to the next step.
Remember after starting your container MySQL take a few minutes to start so run those commands after 3-4 minutes.
docker exec -it container_name bash
# ONCE YOU ARE INSIDE CONTAINER
mysql -u root -p
SHOW DATABASES;
exit
To connect from terminal or command prompt
mysql -h localhost -P 3306 --protocol=tcp -u root -p
I have tried the same thing, and I was facing same problem, but I have noticed one thing, whenever I was trying to run docker container with /bin/bash like as below:
docker container run -it --name test_mysql -e MYSQL_ROOT_PASSWORD=password -p 3306:3306 mysql:latest /bin/bash
After hitting the above command, my container getting start but facing the same error" ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)"
Now, I have tried instead of above command, I have used below command:
docker container run -itd --name test_mysql -e MYSQL_ROOT_PASSWORD=password -p 3306:3306 mysql:latest
docker container exec test_mysql /bin/bash
then using the command
mysql -uroot -P3306 -p
then able to connect, Hope This idea will work in your case.
Thanks

I was able to connect mysql server 5.7 running on my host using the below command:
mysql -h 10.10.1.7 -P 3307 --protocol=tcp -u root -p
where the ip given is my host ip and 3307 is the port forwaded in mysql docker. After entering the command type the password for mysql. That is it. Now you are connected the mysql docker container from the your host machine.
According to the photos, go to the project -> MySQL -> inspect tab in the docker desktop app and modify the information about the database .env file.
.env file example:
DB_CONNECTION=mysql
DB_HOST=0.0.0.0:3306
DB_PORT=3306
DB_DATABASE=testdb
DB_USERNAME=sail
DB_PASSWORD=password
In case this will help somebody:
My prefered solution
add ~/.my.cnf with contents
[client]
user=<yourusername>
password=typethepasswordhere
host=127.0.0.1
port=3306
then from the terminal run >$ mysql and you should get in your sql cmd.
The hardcore alternative
you can also connect like this
docker exec -it containername mysql
To get into the sql cmd
or
docker exec -it contaiinername bash (or sh)
to connect in the container and then run >$ mysql
change "localhost" to your real con ip addr
because it's to mysql_connect()
