ARM cluster

Repo with lab bench setup of a cluster of virtual ARM nodes. This could in a real live world scenario be a bunch of raspberry pi boards

We can bring it all up automatically via a simple

make cluster-up

And then we get a detached tmux session and inside it a terminal for each cluster node we might have been created previously.

Again, simple command to start working with it :)

make cluster-view

And we can then start laborate with some clustered docker swarm workloads :)

Bring cluster up

make cluster-up

Bring cluster down (gracefully)

make cluster-down

Add node to cluster

We can create a node X by using "make cluster-nodeX", like this for a first node :

make cluster-node1

and we can continue add more nodes as needed :

make cluster-node2
make cluster-node3
...

accessing nodes

This lab setup simply use pwd "tjosan" for the nodes and we can login like

sshpass -p tjosan ssh [email protected] uptime

(realworld setup would preferably use ssh keys of course)

node configuration

examples

1. swarmregistry Run a container repository/registry in the cluster. This is needed for all other swarm examples too so start with this one...
2. swarmtest Simple web app for testing out docker swarm cluster.
