Master / slave SQL configuration on 2 vps

We have 2 vps running on same datacenter which share local IP
192.168.1.5
192.168.1.7

We have master / slave running good already on 1 server (1 master sql and 1 slave sql)
We use mariadb as database system

Now we want to setup
1/ 2nd VPS same with 1st vps
2/ make a group of master for 2 vps
3/ setup a connection url to 2 masters
4/ setup a connection url to all slaves node

Example : tcp://192.168.1.7:3306

We need you to build complete 2 dockerfiles for slave and master servers

Output : dockerfiles running well with docker compose
We can connect to mariadb at 3306 (master) 3307 (slave) 3308 (slave) with sql tool
If we write on master - slave automatic replica it

we run it on our environments (all vps running ưubuntu 20.04), we share vps ssh with you and we check together too.

Our budget is 75$, please dont bid if its too less for you. Thank you
