This topology can be used to build and start clusters of the MapR Converged Data Platform.
The clusterdock framework is designed to be run out of its own container while affecting
operations on the host. To avoid problems that might result from incorrectly
formatting this framework invocation, a Bash helper script (clusterdock.sh) can be sourced on a
host that has Docker installed. Afterwards, running any of the binaries intended to carry
out clusterdock actions can be done using the clusterdock_run command.
wget https://raw.githubusercontent.com/clusterdock/framework/master/clusterdock.sh
# ALWAYS INSPECT SCRIPTS FROM THE INTERNET BEFORE SOURCING THEM.
source clusterdock.sh
An environmental variable is used to let the helper script know where to find an image of the mapr
topology. Note that each MapR cluster node requires a dedicated disk or partition. This is passed
when starting the cluster with the --node-disks argument. To start a two-node MapR Converged Data
Platform cluster with default versions, you would simply run
CLUSTERDOCK_TOPOLOGY_IMAGE=clusterdock/topology_mapr clusterdock_run \
./bin/start_cluster mapr --node-disks='{node-1:[/dev/xvdb],node-2:[/dev/xvdc]}'
