How to connect mysql workbench to running mysql inside docker?

Mysql Problem Overview

I am using mysql server inside docker container and able to access inside docker. How to create connection in mysql workbench running on my local(Host Machine).

Solution 1 - Mysql

By default after deployment MySQL has following connection restrictions:

mysql> select host, user from mysql.user;
+-----------+---------------+
| host      | user          |
+-----------+---------------+
| localhost | healthchecker |
| localhost | mysql.session |
| localhost | mysql.sys     |
| localhost | root          |
+-----------+---------------+
4 rows in set (0.00 sec)

Apparently, for the security purposes you will not be able to connect to it outside of the docker image. If you need to change that to allow root to connect from any host (say, for development purposes), do:

Start your mysql image with all port mappings required:

docker run -p 3306:3306 --name=mysql57 -d mysql/mysql-server:5.7

or, if the complete port mapping is required:

docker run -p 3306:3306 -p 33060:33060 --name=mysql57 -d mysql/mysql-server:5.7

2. If this is the fresh installation - grab the default password:

`docker logs mysql57 2>&1 | grep GENERATED`

3. Connect using mysql client directly to the mysqld in docker:

`docker exec -it mysql57 mysql -uroot -p`

4. If this is the fresh installation you will be asked to change the password using ALTER USER command. Do it.

Run SQL:

update mysql.user set host = '%' where user='root';
Quit the mysql client.
Restart the container:

docker restart mysql57

Now you will be able to connect from MySQL Workbench to

host: `0.0.0.0` 
port: `3306`

After all the changes the query will show:

select host, user from mysql.user;
+-----------+---------------+
| host      | user          |
+-----------+---------------+
| %         | root          |
| localhost | healthchecker |
| localhost | mysql.session |
| localhost | mysql.sys     |
+-----------+---------------+

Solution 2 - Mysql

You have to do few configuration in you docker container. Please follow the following steps.

Specify mysql configuration block in your docker-compose.yml. I have following mysql block under services object in my docker-compose.yml file.

 services:
     db:
         image: mysql
         volumes:
             - "./.data/db:/var/lib/mysql"
         environment:
             MYSQL_ROOT_PASSWORD: root
             MYSQL_DATABASE: mydb
             MYSQL_USER: user
             MYSQL_PASSWORD: pass
         ports:
             42333:3306

Restart docker container and run following commands to get to the bash shell in the mysql container
```
 docker ps
 docker exec -it <mysql container name> /bin/bash 
```

Inside the container, to connect to mysql command line type,

    mysql -u root -p


Use **MYSQL_ROOT_PASSWORD** as specified in the docker-compose.yml . Execute following commands to create new user.

    create user 'user'@'%' identified by 'pass';
    grant all privileges on *.* to 'user'@'%' with grant option;
    flush privileges;

The percent sign (%) means all ip's. Restart the docker container.

3. In your MySQL Workbench provide the connection details. Use MYSQL_PASSWORD as specified in your docker-compose.yml file.

You should now be able to connect to your mysql container.

Solution 3 - Mysql

Suppose you have the next content of your docker-compose file:

database: image: mysql:5.6 volumes: - dbdata:/var/lib/mysql environment: - "MYSQL_DATABASE=homestead" - "MYSQL_USER=homestead" - "MYSQL_PASSWORD=secret" - "MYSQL_ROOT_PASSWORD=secret" ports: - "33061:3306"

For localhost just use host 127.0.0.1 and 33061 port

Solution 4 - Mysql

2 docker-related conditions:

first, your docker run must map the mysql port to an host port:
```
  docker run -p host:container
```

(for instance: docker run -d -p 3306:3306 tutum/mysql)

second, if you are using docker in a VM (docker-machine, with boot2docker), you need to use the ip of docker-machine ip <VMname>, with the host mapped port.
```
  http://$(docker-machine ip <VMname>):hostPort
```

If you need to use localhost, you would need to do some port forwarding at the VirtualBox level:

VBoxManage controlvm "boot2docker-vm" natpf1 "tcp-port3306,tcp,,3306,,3306"
VBoxManage controlvm "boot2docker-vm" natpf1 "udp-port3306,udp,,3306,,$3306"

(controlvm if the VM is running, modifyvm is the VM is stopped) (replace "boot2docker-vm" by the name of your vm: see docker-machine ls)

2 mysql-related conditions:

As illustrated in nkratzke/EasyMySQL/Dockerfile, you need to enable remote access:

  # Enable remote access (default is localhost only, we change this
  # otherwise our database would not be reachable from outside the container)
  RUN sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf

You need to create users when startig your database in your docker image.
See for instance nkratzke/EasyMySQL/start-database.sh, which is called by the Dockerfile CMD:

  /usr/sbin/mysqld &
  sleep 5
  echo "Creating user"
  echo "CREATE USER '$user' IDENTIFIED BY '$password'" | mysql --default-character-set=utf8
  echo "REVOKE ALL PRIVILEGES ON *.* FROM '$user'@'%'; FLUSH PRIVILEGES" | mysql --default-character-set=utf8
  echo "GRANT SELECT ON *.* TO '$user'@'%'; FLUSH PRIVILEGES" | mysql --default-character-set=utf8
  echo "finished"

Solution 5 - Mysql

Specify your configuration docker-compose.yml. More details here. Example:

version: '3.1'

services:
  mysql:
    image: mysql:5.6
    container_name: test-mysql
    ports:
      - 3306:3306
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: password

Run this comandsdocker-compose up and another terminal run docker ps to see your container.
Access your docker: docker exec -it test-mysql bash
Inside the container, to connect to mysql command line type,run mysql -u root -p.
Create a new user
Finally config your MySQL Workbench

Solution 6 - Mysql

I was trying to connect from Mysql Workbench but it wasn't allowing me. Turned out, I forgot to mention the port. Here is the complete command to run and then connect from workbench:

Step 1 - Run docker container:

docker run --name mysql8 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=testdb -e MYSQL_USER=admin -e MYSQL_PASSWORD=root -d mysql:8.0.20

Explanation of above command:

Mysql v8.0.20
```
mysql:8.0.20
```
Run as a detached container (ctrl + c won't stop the container)
```
-d
```
Container name
```
--name mysql8
```
Port expose
```
-p 3306:3306
```

Set environment variables

 -e MYSQL_ROOT_PASSWORD=root
 -e MYSQL_DATABASE=testdb
 -e MYSQL_USER=admin
 -e MYSQL_PASSWORD=root

You can see live logs of the container by:

docker logs mysql8 -f

Step 2 - Connect from Mysql Workbench:

host: localhost
port: 3306
user: admin
password: root

Solution 7 - Mysql

@Krishna's answer worked but with a minor change - user was added as follows

create user 'user'@'%' IDENTIFIED WITH mysql_native_password BY 'pass';

see https://stackoverflow.com/questions/49194719/authentication-plugin-caching-sha2-password-cannot-be-loaded

Solution 8 - Mysql

I found a video that showed another way to get this to work. You can specify the IP address when passing in the port number. That is, something like -p 127.0.0.1:3307:3306 instead of just -p 3307:3306 I've never seen that before https://www.youtube.com/watch?v=20om-9Gwuc0#t=7m

Example start command

docker run -d -e MYSQL_ROOT_PASSWORD=test --name mysql8 -p 127.0.0.1:3307:3306 mysql:8

Then I was able to use MYSQL Workbench to connect to 127.0.0.1 at port 3307.

Solution 9 - Mysql

I got solution for this by setting field value in Hostname: 127.0.0.1 (Localhost), port by default 3306 with your creds.

Solution 10 - Mysql

I followed instructions shown in mysql docker hub. wrote this docker-compose.yml

version: '3.1'

services:
  db:
    image: mysql
    command: --default-authentication-plugin=mysql_native_password
    environment:
      MYSQL_ROOT_PASSWORD: example
    ports:
      - 3306:3306

Go to mysql workbench when you are making connection make sure to clear password in the parameters. now enter password(in my case example)

Solution 11 - Mysql

You will need to go in Settings -> Network -> Port Forwarding and configure:

Host/Guest IP to 0.0.0.0
Host/Guest Port to 3306

Solution 12 - Mysql

I solved it downloading the last version of MySQL Workbench, then I used host 0.0.0.0 with port 3306.
