⁠lnmp

for docker lnmp galera test. test in localhost like: docker network create david-net docker run -p 80:80 --name n1 --net=david-net -d novice/lnmp --wsrep-new-cluster --wsrep-cluster-address=gcomm:// docker run --name n2 --net=david-net -d novice/lnmp --wsrep-cluster-address=gcomm://n1 docker run --name n3 --net=david-net -d novice/lnmp --wsrep-cluster-address=gcomm://n1

docker exec -t n1 mysql -uroot -pfreego -e 'show status like "wsrep_cluster_size"' +--------------------+-------+ | Variable_name | Value | +--------------------+-------+ | wsrep_cluster_size | 3 | +--------------------+-------+

⁠build locally

docker build -t novice/lnmp .

⁠run it on several host like this

referrence and modified from: http://galeracluster.com/2015/05/getting-started-galera-with-docker-part-2-2/⁠ suppose following 3 nodes n1 10.10.10.10 n2 10.10.10.11 n3 10.10.10.12 A simple cluster setup would look like this:

n1$ docker run -p 80:80 -p 3306:3306 -p 4567:4567 -p 4444:4444 -p 4568:4568 -d

n2$ docker run -d -p 80:80 -p 3306:3306 -p 4567:4567 -p 4444:4444 -p 4568:4568
