How can I get through http to phpmyadmin of a docker container?

Question

Docker

Hello, in general, the problem is this:
There is a Virtualbox machine (Debian + docker) that has a network card connected via NAT. Guest OS
IP address 10.0.2.15 eth0 interface
IP address 10.0.2.15 docker0 interface IP address 172.17.0.1 Bridge
IP address br-35f4538777fe (arbitrary) 172.72.20.1
phpmyadmin IP address (docker container name phpmyadmin) 172.72.20.5
apache2 IP address (docker container name apache2) 172.72.20.2
apache2 container became available via http after settings in docker-compose.yml
added the following
ports item:
- "80:80"
------------------ ------------------------------
phpmyadmin:
image: phpmyadmin/phpmyadmin:latest
links:
- mysql:mysql
environment:
PMA_HOST: mysql
volumes:
- ./docker/config/phpmyadmin/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php
networks:
self:
ipv4_address: 172.72.20.5
B guest OS (Debian) through port 80 at 172.72.20.5 everything works.
You need to bring 172.72.20.5 outside to the host machine so that you can work with it.

In general, I changed the config in docker-compose.yml
phpmyadmin:
image: phpmyadmin/phpmyadmin:latest
links:
- mysql:mysql
environment:
PMA_HOST: mysql
volumes:
- ./docker/config/phpmyadmin/config.user.inc.php:/etc /phpmyadmin/config.user.inc.php
networks:
self:
ipv4_address: 172.72.20.5
ports:
- "8080:80" # added this item
------------------- ----------------------------------------
Then I did port forwarding in VirtualBox in the network settings guest machine (NAT)
And everything worked.
