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 $PWD/init.sql:/docker-entrypoint-initdb.d/init.sql \
... \
mysql
If you're just trying to experiment with SQL commands, a serverless database like SQLite might fit your needs better.
the -p parameter is for the ports to be published and should not be part of the -it interactive, that should be your error,
Have a read of the docker run command, in the docker documentation,
https://docs.docker.com/engine/reference/run/
I'm required to build a multi-database MySQL container, this was straight forward as I followed this tutorial: https://dzone.com/articles/multiple-mysql-databases-with-one-mysql-container
Now I have to run my wordpress container and connect it to one of these databases, I tried what I already know:
docker run -e WORDPRESS_DB_PASSWORD=pass --network wordpress --name wordpress --link mysqldb:mysql -p 4123:80 -v "$PWD/html":/var/www/html -d wordpress
where mysqldb is the container's name but with no luck whatsoever.
What is the proper syntax to link wordpress container with one of these databases? They are two, the other one should be used for another purpose.
I don't have the liberty to use two MySQL containers, any advice is highly appreciated, thanks.
the name when you linked mysqldb:mysql is the database server hostname. In your sample, it is mysql
You can cat /etc/hosts to confirm the mysql hostname in your application container wordpress
Second, you don't have to build a seperate multi-database containers, you just link several times.
# create first mysql database container.
$ docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql
4914c6fbb3e870b530fc5713908cd918ad3d1c43ebbeb460b878857328934f95
# create second mysql database container.
$ docker run --name some-mysql2 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql
72090be34a5d62ea53edd87e4b513ad5c0c413fe8b223fe36c2aae6938fd77c4
# run your application with links
$ docker run -d --name wordpress --link some-mysql:mysql1 --link some-mysql2:mysql2 wordpress
f1d6fbc2fcf30862efd0a4a4882425e359a2442c1476c0256c338e80a46ae66d
You can check the hostname in wordpress container
$ docker exec -ti f1 bash
root#f1d6fbc2fcf3:/var/www/html# cat /etc/hosts
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.2 mysql1 4914c6fbb3e8 some-mysql # <= here is the first mysql hostname
172.17.0.3 mysql2 72090be34a5d some-mysql2 # <= here is the second mysql hostname
172.17.0.4 f1d6fbc2fcf3
root#f1d6fbc2fcf3:/var/www/html#
I just pulled and run the official Docker MySQL image and have it running locally on my machine:
docker run --name mydb -e MYSQL_ROOT_PASSWORD=12345 -d mysql:5.7.11
The instructions on that screen tell you how to connect to the MySQL server (container) from inside yet another container (which is configured as a command-line client). But I have a generic JDBC fat client (SQuirreL) and am wondering how to connect to my docker container.
For the JDBC connection string, I need to provide both a hostname and a dbname, what can I use? I would imagine the Docker container is somehow addressable from my host OS, but I haven't actually created any databases yet, so I'm not sure what dbname value I can supply:
jdbc:mysql://<hostname>:3306/<dbname>
You could run your instance with forwarding 3306:
$ docker run --expose=3306 -p 3306 mysql
See incoming ports.
The you specify:
jdbc:mysql://127.0.0.1:3306/<dbname>
You command become:
$ docker run --name mydb -e MYSQL_ROOT_PASSWORD=12345 -d --expose=3306 -p 3306 mysql:5.7.11
You might need to change the MySQL configuration.
Can go inside the container with:
$ docker exec -it mydb bash
And then you could:
$ echo "bind-address = 0.0.0.0" >> /etc/mysql/my.cnf
Don't forget to reload mysql.
Then you have to create the database and import your schema (if needed).
$ mysql -uroot -p12345 -e"CREATE DATABASE mydb"
$ mysql -uroot -p12345 mydb < mydb-schema.sql
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

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()
