I found out about Vitess which let you shard MySQL database. I want to use the docker image of both MariaDB and Vitess but I'm not quite sure what to do next. I'm using CentOS 7.
I installed the images
docker pull mariadb
docker pull vitess/root
docker pull vitess/orchestrator
Log inside the vitess image
sudo docker run -ti vitess/root bash
As the website said, make build
make build
I set up the variables
export VTROOT=/vt
export VTDATAROOT=/vt/vtdataroot
The manual said it was in the home directory but in the image it's at root.
But after that I'm stuck. I laucnh zookeeper : ./zk-up.sh
Starting zk servers... Waiting for zk servers to be ready... Started zk servers. ERROR: logging before flag.Parse: E0412
00:31:26.378586 132 syslogger.go:122] can't connect to syslog
W0412 00:31:26.382527 132 vtctl.go:80] cannot connect to syslog:
Unix syslog delivery error Configured zk servers.
Oops, okay, let's continue...
./vtctld-up.sh for the web internace
Starting vtctld...
Access vtctld web UI at http://88bdaff4e181:15000
Obviously I cannot access that link since it's in docker on a headless server
./vttablet-up.sh suppose to bring up 3 vttablets, but MariaDB is in another docker, not yet started and if I open the file it is not apparent how to set it up.
Is there any MySQL or PostgreSQL sharding solution more easily installable? Or how can I set this up?
(Docker noob here sorry)
Thanks!
If you need multiple container orchestrated, best bet is to use docker-compose . You can define all the application dependencies as separate containers and network them to be accessible from each other.
