Hey friend,
Very nice your tutorial.
On the first command (to install mysql on the container), what happens if I have already a mysql local running on 3306 port?
I also would like to know how to create a container with mysql + java + MyApplication.jar, how can I do that?
Thanks for your feedback. See my other posts about this subject. About port, you received an error. Just change port of left side.

Great Tutorial !!
I guess I was stuck on the container access issue.
CREATE USER 'demo_java' IDENTIFIED BY 'java';
grant all on . to 'demo_java'@'%' identified by '1234';
FLUSH PRIVILEGES;
This solved it. Thanks!!
Can you please also do an Enterprize level Spring Boot Running in docker and orchestrated on Kubernetes tutorial? That'd be great.. :)
Thanks for your feedback. I wrote one serie about this.

Hi ! Thanks for your post, it has been really helpfull ! I have yet a question. How can we save the state of the container in order to reuse it later on a different computer ? How to prevent data loss ?
Pode explicar pfv esse trecho de codigo:
De 'demo_java' pro final do codigo nao entende!
CREATE USER 'demo_java' IDENTIFIED BY 'java';
grant all on . to 'demo_java'@'%' identified by '1234';
FLUSH PRIVILEGES;
O que faz essas tres linhas?

Hi friend,
I tried all the three option of jdbc url, but did not work. Request your help.
spring.datasource.url=jdbc:mysql://localhost:3306/hello_java
spring.datasource.url=jdbc:mysql://:3306/hello_java
spring.datasource.url=jdbc:mysql://:3306/hello_java
Just to tell you My Machine is Windows 10 pro.
Spring boot codebase running on my local eclipse.
And I have Docker Desktop installed in my System where I have created Mysql container.
Following error comes when I Run as Spring Boot App:

I ran to the same situation. The root cause is MySQL Server and Clients are running in two different versions. Thats the reason you are seeing handshake connection issue because of mysql protocol version mismatch.
Run you server with most recent version that should solve the problem.
docker run --name mysql57 -p 3306:3306 \
-e MYSQL_ROOT_PASSWORD=1234 \
-e MYSQL_USER=demo_java \
-e MYSQL_PASSWORD=1234 \
-e MYSQL_DATABASE=hello_java \
-d mysql/mysql-server
or Specify the compatible JDBC driver version in pom.xml
