Starting the environment

To start up the Vagrant Kubernetes multi node environment with the default of two worker nodes + a master (not parallel) run:

$ make up

NOTE Your kubectl is automatically configured to use a context for the
created cluster, after the master VM is started.
The context is named after the directory the Makefile is in.

Faster (parallel) environment start

To start up 4 VMs in parallel run (-j flag does not control how many (worker) VMs are started, the NODE_COUNT variable is used for that):

$ NODE_COUNT=3 make up -j4

The flag -j CORES/THREADS allows yout to set how many VMs (Makefile targets) will be run at the same time.
You can also use -j $(nproc) to start as many VMs as cores/threads you have in your machine.
So to start up all VMs (master and three nodes) in parallel, you would add one to the chosen NODE_COUNT.

Show status of VMs

$ make status
master                    not created (virtualbox)
node1                     not created (virtualbox)
node2                     not created (virtualbox)

Shutting down the environment

To destroy the Vagrant environment run:

$ make clean
$ make clean-data

Copy local Docker image into VMs

The make load-image target can be used to copy a docker image from your local docker daemon to all the VMs in your cluster.
The IMG variable can be expressed in a few ways, for example:

$ make load-image IMG=your_name/your_image_name:your_tag
$ make load-image IMG=your_name/your_image_name
$ make load-image

You can also specify a new image name and tag to use after the image has been copied to the VM's by setting the TAG variable.
This will not change the image/tag in your local docker daemon, it will only affect the image in the VM's.

$ make load-image IMG=repo/image:tag TAG=new_repo/new_image:new_tag

Data inside VM

See the data/VM_NAME/ directories, where VM_NAME is for example master.

make Targets

See make Targets doc page for a full list of all make targets (make help).
