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).
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
If this is the fresh installation - grab the default password:
docker logs mysql57 2>&1 | grep GENERATED
Connect using mysql
client directly to the mysqld in docker:
docker exec -it mysql57 mysql -uroot -p
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 |
+-----------+---------------+
