The Docker run command is:
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=flurpgraSS -d mysql:5.7
Docker Desktop shows the container:
I can access the server from the CLI launched by Docker Desktop and the root account appears to be OK:
I can't access the server using MySQL Workbench
We might need to expose port from docker by -p parameter, otherwise, we can't access it outside.
docker run --name some-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=Danger42! -d mysql:5.7
There is some description from Container networking
-p 3306:3306：Map TCP port 3306 in the container to port 3306 on the Docker host.

I'd like to test webtrees PHP docker. They suggest connecting to a mysql docker using --link mysql:db, as follows:
docker run -d -p 80:80 --name webtrees --link mysql:db -v /webtrees/data:/var/www/html/data -v /webtrees/media:/var/www/html/media -e DISABLE_SSL=TRUE -e PORT=80 --restart always dtjs48jkt/webtrees
Their README says:
The image does not contain a MySQL database. Instead you have to use a separate MySQL instance. For example you could use the
MySQL Docker Image. Using the --link parameter a direct connection to
the database in an other container could be established. If you use
the --link parameter it is sufficient to set as database hostname db
and port 3306. The database user must have all access rights to
create the necessary database and tables.
However the webtrees container cannot access the mysql server. How I correctly link these two docker containers?
I tried using the official mysql docker image as follows:
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -e MYSQL_DATABASE=webtrees -e MYSQL_USER=my_user -e MYSQL_PASSWORD=my_pwd -d mysql:5.5
but then I don't know how to link webtrees docker container with the mysql container.
Also, how can I use the mysql client? the documentation gives this example, but I don't understand what are the correct parameters for netowrk and -h:
$ docker run -it --network some-network --rm mysql mysql -hsome-mysql -uexample-user -p
Regarding your first question, the --link option for docker run is deprecated according to the documentation, so I wouldn't recommend using it.
With the amount of configuration required, I'd recommend setting up a docker-compose.yml instead. I set up the configuration you require like this:
version: '3.0'
services:
webtrees:
image: dtjs48jkt/webtrees
restart: always
ports:
- 80:80
environment:
- DISABLE_SSL=TRUE
- PORT=80
volumes:
- /webtrees/data:/var/www/html/data
- /webtrees/media:/var/www/html/media
networks:
- my-network
mysql:
image: mysql:5.5
environment:
- MYSQL_ROOT_PASSWORD=my-secret-pw
- MYSQL_DATABASE=webtrees
- MYSQL_USER=my_user
- MYSQL_PASSWORD=my_pwd
networks:
- my-network
networks:
my-network:
To run the containers, use:
docker-compose up --detach
What this will do is spin up a mysql container and a webtrees container according to the configuration you specified in your question with a network called my-network.
In the web interface of web trees on http://localhost/ you can make it connect to the mysql container with the following configuration, so it will connect to it through the docker network:
Since the service name in the docker-compose.yml is mysql, the required hostname is mysql.
Basically you need to have all the containers (mysql DB server, mysql client and application) in the same Docker network. By default they are not. Alternatively, --link can be used to link them (as shown in webtrees run example), but it's considred as legacy feature and network should be used instead of that.
So what you need to do:
Create custom Docker network:
docker network create user-network
Run mysql server in that network. Name should be db, because webtrees relies on that hostname for DB:
docker run --name db --network user-network -e MYSQL_ROOT_PASSWORD=my-secret-pw -e MYSQL_DATABASE=webtrees -e MYSQL_USER=my_user -e MYSQL_PASSWORD=my_pwd -d mysql:5.5
Run mysql client in the same network:
docker run -it --network user-network --rm mysql mysql -hdb -umy_user -p
Finally you can run an app in the same network:
docker run -d -p 80:80 --name webtrees --network user-network -v /webtrees/data:/var/www/html/data -v /webtrees/media:/var/www/html/media -e DISABLE_SSL=TRUE -e PORT=80 --restart always dtjs48jkt/webtrees
After that web app should be accessible from your browser under http://localhost/
I am Running a MySQL Docker image and creating database and table. The container is lauched with the command:
docker run --network host -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=root -d mysql/mysql-server
Spark is running on my host machine, So i want to write data from Spark into the database running in the container.
But the connection does not succeed and I am getting an Exception:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
You can try this 2 solutions:
Check if your connection URL is not wrong in your java file.
Check if your container accept connections that is not localhost of the container:
Go to your cmd and enter in the container:
docker exec -it containerID /bin/bash
install vim inside container apt install vim
vim /etc/mysql/mysql.conf.d/mysqld.cnf
comment bind-adress or make it listen to 0.0.0.0
exit from container
restart
Hope this help.
As Schwarz54 mentioned in his answer, it could be host issue.
I usually pass it at the time of initialising the container using the MYSQL_HOST parameter.
docker run --name mysql_5.7 -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root1234 -e MYSQL_HOST=localhost mysql:5.7
I think you don't have to map the ports if you are running it on the host network.
docker run --name mysql_5.7 -d --network host -e MYSQL_ROOT_PASSWORD=root1234 -e MYSQL_HOST=localhost mysql:5.7
You can mount a local directory to the local container if you want the data to be persisted across container restarts using -v flag:
mkdir -p /Users/projects/data/mysql5.7
And mount this directory in the container at /var/lib/mysql
docker run --name mysql_5.7 -d --rm -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root1234 -e MYSQL_HOST=localhost -v /Users/projects/data/mysql5.7:/var/lib/mysql mysql:5.7
Iam beginner to docker and iam working on mysql and node.js I run mysql docker container as
docker run --name docker-mysql -e MYSQL_ROOT_PASSWORD=abc123 -d mysql:latest
and result of docker ps is showing mysql container is running
and docker logs says
MySQL init process done. Ready for start up.
how to connect with this container in workbench or in my application
Try this:
docker run -p 3306:3306 --name docker-mysql -e MYSQL_ROOT_PASSWORD=abc123 -d mysql:latest
This will bind the port 3306 on your local machine to the docker image. You should be able to connect to the database with localhost & port 3306 with username root and password abc123.
I just tested it and it works like a charm.
If you are struggling with the error:
failed to connect to localhost at 33016" details = Authentication
plugin 'caching_sha2_password' cannot be loaded:
dlopen(/usr/local/mysql/lib/plugin/caching_sha2_password.so, 2): image
not found
Update your MySQL-workbench.
If that doesn't work you will need to add a native password to the root user. Here is how:
Connect to your docker image via bash:
docker exec -it docker-mysql bash
Log into mysql as root
mysql --user=root --password
Enter the password for root (Default is 'root', but 'abc123' in this example)
Finally Run:
ALTER USER 'root' IDENTIFIED WITH mysql_native_password BY 'abc123';
You need to expose the port
Use -p, or -P
-p is bound to a custom port, -P will randomly assign a port to you.
:latest does not need to add, docker will help you add.
The final command should look like this:
docker run -dit -P --name docker-mysql -e MYSQL_ROOT_PASSWORD=abc123 mysql:latest
Then use xx to see the exposed ports:
docker port docker-mysql
Check which port of the machine is mapped to port 3306 of the container, My result is:
33060/tcp -> 0.0.0.0:32818
3306/tcp -> 0.0.0.0:32819
Now you can connect to this port via software or code.
For development best way is to connect the container to "host" network
docker run --name docker-mysql --network host -e MYSQL_ROOT_PASSWORD=abc123 -d mysql:latest
When you will move to staging/prod environment consider to use some orchestration solution.
Run docker inspect container_id its will show container port but will not show host port bind. By Default running without -p flag it will assign port to container but will not expose host port , so to achieve this you shout try -p flag, -p 3306:3306 in docker run command.
I just created a mysql docker container using
docker run -p 3310:3310 --restart always --env MYSQL_ROOT_HOST=% --name=ipca-mysql -e MYSQL_ROOT_PASSWORD=admin -d mysql/mysql-server:5.7
I am able to connect to my database using docker exec -ti ipca-mysql bash and mysql -u root -p
But when I tried to connect to my database at localhost:3310 using mysql workbench I get:
lost connection to mysql server at 'reading initial communication
packet' system error 0
Any idea what is this issue?
MySQL container start using this command it's worked.
docker run -p 3310:3306 --restart always --env MYSQL_ROOT_HOST=% --name=ipca-mysql -e MYSQL_ROOT_PASSWORD=admin -d mysql/mysql-server:5.7
You could use this docker command:
docker run --name mysql-tacs -e MYSQL_ROOT_PASSWORD=root -d -p 3310:3306 mysql
In the link below there is a video which shows step by step the creation of mysql server with docker until the connection in its server using MySQL Workbench.

I am using Docker for Windows, on Windows 10 Enterprise. I am trying to connect to a container that is running mysql. I followed the instruction here https://hub.docker.com/_/mysql/ and I used this command to start the container docker run --name memories -e MYSQL_ROOT_PASSWORD=password -d mysql:5.6
if I type docker ps I get
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
300248b56399 mysql:5.6 "docker-entrypoint.sh" About an hour ago Up About an hour 3306/tcp memories
However I cannot figure out how to connect to this container from the host. I have tried localhost and 127.0.0.1. Each time I get an error like this
/* Connecting to 127.0.0.1 via MySQL (TCP/IP), username root, using password: Yes ... */
/* Can't connect to MySQL server on '127.0.0.1' (10061) */
Any suggestions?
I guess it was more simple than I thought. I had to publish port 3306
docker run -p 3306:3306 --name memories -e MYSQL_ROOT_PASSWORD=password -d mysql:5.6
