I want to change the default exposed port for mysql docker container, but if i try to use this command:
docker run --detach --name=test-mysql -p 52000:52000 --env="MYSQL_ROOT_PASSWORD=mypassword" mysql
It does not work. mysql -uroot -pmypassword -h 127.0.0.1 -P 52000
Warning: Using a password on the command line interface can be insecure.
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0
If I use the standard port 3306:3306 then it works fine, but i want change the port. Is it possibile?
I had already tried -p 52000:3600 , but i have always gotten:
mysql -uroot -pmypassword -h 127.0.0.1 -P 52000
Warning: Using a password on the command line interface can be insecure.

You need to map the container-port 3306 on the prefered TCP port (of your server):
-p <host_port>:<container_port> (map container_port xx on host_port yy)
So for your mysql
docker run --detach --name=test-mysql -p 52000:3306 --env="MYSQL_ROOT_PASSWORD=mypassword" mysql
there is also a second option:
don't map a port to another port but let mysql itself run directly on another port using the MYSQL_TCP_PORT-variable.
example:
docker run --detach --name=test-mysql --env="MYSQL_TCP_PORT=52000" mysql
