将 docker MySql 连接到本地主机 mysql

Question

I have used the following command for port mapping

sudo docker run -d -p 3306:33060 --name App1 APP/framework:app

where 3306 port belongs to localhost machine MySQL and 33060 is the port into a docker container, so communication is happening between 3306:33060 in docker.I'm getting issue as below:

sudo docker run -d -p 3306:33060 --name App1 APP/framework:app fc1ffe98b2f2e6299a3070be8296d8b530ef4bdb3bd4cfd79d28ffc535a361c1

docker: Error response from daemon: driver failed programming external connectivity on endpoint App1 (30ec933973acf63a48ef9a20b0027af18bd23e1f36cf852e2e3e3758eaa1f843): Error starting userland proxy: listen tcp 0.0.0.0:3306: bind: address already in use.

I don't want mysql in docker container to create image.Just want to open random port and map 3306 and host-ip to communication with port in docker ie 33060

Can anyone please suggest any way to resolve this that would be appreciated? Thank you.

Answer 1

Some examples from the docker documentation, before the colon is the container port, and after the colon is the container host port.

-p 8080:80
Map TCP port 80 in the container to port 8080 on the Docker host.

-p 192.168.1.100:8080:80
Map TCP port 80 in the container to port 8080 on the Docker host for connections to host IP 192.168.1.100.

-p 8080:80/udp
Map UDP port 80 in the container to port 8080 on the Docker host.

-p 8080:80/tcp -p 8080:80/udp
Map TCP port 80 in the container to TCP port 8080 on the Docker host, and map UDP port 80 in the container to UDP port 8080 on the Docker host.

If you want to access port 3306 in the host from your docker container, you can use

sudo docker run -d --net host --name App1 APP/framework:app

and you container will share the host's network meaning that you could do localhost:3306 from inside your container and "localhost" on the container would be exactly the same thing as "localhost" on the host.
