A YugabyteDB users asked about running Nakama ((server for realtime social and web & mobile game apps)) on YugabyteDB
As YugabyteDB is PostgreSQL-compatible, this is as easy as pointing the connection to the new database. The Nakama documentation shows an example of docker-compose.yaml for PostgreSQL and CockroachDB.
The idea is:
- put
CREATE DATABASEin an itit script directory - start YugabyteDB with
bin/yugabyted start --daemon=false --listen=0.0.0.0 --initial_scripts_dir=/tmp/sql --base_dir=/var/lib/yugabytedb - and before connecting, what to be sure that port 5433 is up:
until echo > /dev/tcp/yugabytedb/5433 ;
do
echo "Waiting for YugabyteDB to be up..." ; sleep 1 ;
done ;
echo "YugabyteDB is up 🚀 - check http://localhost:7000" ; sleep 5 &&
Here is my docker-compose-yaml:
version: '3'
services:
yugabytedb:
image: yugabytedb/yugabyte:2.14.1.0-b36
environment:
- POSTGRES_DB=nakama
