Dockerfile passing wrong mysql host ip address - mysql

Question

I created a build on my local machine and was working great. Now
trying to do same in the server.It is not passing the host-ip set in
Dockerfile but passing 172.17.0.3 and throwing the bellow error
Here is the error:
Step 22/25 : RUN cd /usr/html/bin && ./magento setup:config:set --db-host=172.17.0.2 --db-name=mydb --db-user=tara --db-password=password
---> Running in 7bbe53f5d054
SQLSTATE[HY000] [1045] Access denied for user 'tara'#'172.17.0.3' (using password: YES)
[InvalidArgumentException]
Parameter validation failed
*Where the host ip comes from the IP address of another running container. which is 172.17.0.2 *
Why is it taking wrong IP address during connection
HERE is the dockerfile:
