In this blog post, we’ll point to a new Docker image for Percona Server for MySQL Group Replication.
Our most recent release of Percona Server for MySQL (Percona Server for MySQL 5.7.17) comes with Group Replication plugins. Unfortunately, since this technology is very new, it requires some fairly complicated steps to setup and get running. To help with that process, I’ve prepare Docker images that simplify its setup procedures.
You can find the image here: https://hub.docker.com/r/perconalab/pgr-57/.
To start the first node (bootstrap the group):
|
1 |
docker run -d -p 3306 --net=clusternet -e MYSQL_ROOT_PASSWORD=passw0rd -e CLUSTER_NAME=cluster1 perconalab/pgr-57<br> |
To add nodes into the group after:
|
1 |
docker run -d -p 3306 --net=clusternet -e MYSQL_ROOT_PASSWORD=passw0rd -e CLUSTER_NAME=cluster1 -e CLUSTER_JOIN=CONTAINER_ID_FROM_THE_FIRST_STEP perconalab/pgr-57<br> |
You can also get a full script that starts “N” number of nodes, here: https://github.com/Percona-Lab/percona-docker/blob/master/pgr-57/start_node.sh
