Upgrade Tests

This directory has a set of scripts for Nomad upgrade testing. The cluster's configs are also included here. For ease of testing, the configs and node names use names like "server1" and "client1" and the data directories are in "/tmp/server1", "/tmp/client1"`, etc

Start a cluster

Use run_cluster.sh to start a 3 server, 2 client cluster locally. The script takes the path to the Nomad binary. For example, to run a 0.8.7 Nomad cluster do:

$ ./run_cluster.sh /path/to/Nomad0.8.7

Run cluster also assumes that consul exists in your path and runs a dev agent

Stop nodes

Use the kill_node script to stop nodes. Note that for quorum, you can only stop one server at a time. For example, to stop server1 do :

$ ./kill_node.sh server1

This does kill -9 and is not meant to test graceful shutdowns.

To stop client1 do :

$ ./kill_node.sh client1

Start nodes

Use the run_node script to start nodes. In general, upgrade testing involves shutting down a node that's running an older version of nomad and starting it back up with a newer binary. For example, to run Nomad 0.9 as server1 do:

$ ./run_node.sh /path/to/Nomad0.9 server1

This will use the same data directory, and should rejoin the quorum

Another example - to start client1 do :

$ ./run_node.sh /path/to/Nomad0.9 client1
