//sysctl -w net.ipv4.ip_forward=1firewall-cmd --zone=public --add-masquerade --permanent
firewall-cmd --reload
systemctl restart docker
docker run busybox nslookup google.comThen... it should work properly without any issues...
This method should not be used as a solution....

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1If you set the size incorrectly, delete the swap using the commands below and set it up again.
swapoff /var/swap.1
rm -f /var/swap.1Well... that's how I wrote up installing Docker on CentOS 8..
Now... since most work is done with Docker, I guess you can just run the commands directly on the VPS to install it and get to work...
Vultr has added a location in Korea this time... awesome >.<
docker exec -it 77d8be03cdf0 /bin/bash
php artisan migrateOkay... now connect to the container using bash and run migrate. Done!!
To add a note about this at 2 AM on May 17, you shouldn't use the above
firewall-cmd --zone=public --add-masquerade
to solve it....
I'll explain why in the link.
