问题
I have installed docker on my mac. I have MySQL container which is running on my local machine (MAC).
Docker ps command is giving me below output -
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b5c50b2d334a test_mysql2 "docker-entrypoint.s…" 2 hours ago Up 2 hours (healthy) 0.0.0.0:32783->3306/tcp test_mysql2_1
I know username and password to the mysql which would be setup up in the container.
I want to connect to mysql and run some queries But I am not able to figure out how to connect to it. Any help will be appreciated.

Do you want to Connect to MySQL through Docker if yes; Kindly follow this step by step procedure that I am using.
Step 1 : Pull MySql image from docker hub. The following command will pull the latest mysql image.
cli> docker pull mysql
Step 2: Run a container from this image. ‘-name’ gives a name to the container. ‘ -e’ specifies run time variables you need to set. Set the password for the MySQL root user using ‘MYSQL_ROOT_PASSWORD’. ‘-d’ tells the docker to run the container in background.
cli> docker run --name=testsql -e MYSQL_ROOT_PASSWORD=rukshani -d mysql
This will output a container id; which means that the container is running in the background properly.
Step 3: Then check the status of the container by issuing, ‘docker ps’ command
cli> docker ps
Now you should be able to see that MySQL is running on port 3306.
Step 4: To checkout the logs of the running container use the following command
cli > docker logs testsql
Step 5: Find the IP of the container using following. Check out the “IPAddress” from the output, this will tell you the IP address.
cli> docker inspect testsql
Now you should be able to connect to MySQL using tIPs ip address on port 3306.
Base on what I understand from your question, this is what you need. (I hope so)
(This is not my own documentation, I only like to document everything most especially those procedure that I cannot put in my head, so that if ever the same thing happen or I need same procedure in the future, I will not waste my time to research again, but instead I will open my notes and run the commands.)
回答2:
As you can see in the output of docker ps, the port 32783 (local machine) is mapped to the port 3306 inside the docker container. If you are using a MySQL Client (e.g. MySQL Workbench) you should be able to connect using ip localhost and port 32783. If not, you should go with docker exec and then open a interactive mysql shell inside the container (As mulg0r commented).
