This adds a few features:
- ./workshopctl kubereset TAG (closes#306)
- remove python-setuptools (prepare for #353)
- ./workshopctl weavetest TAG (help detecting weave issues
like we had at OSCON, July 2018)
- remove a bit of dead code
This allows to manage groups of VMs across multiple infrastructure
providers. It also adds support to create groups of VMs on OpenStack.
WARNING: the syntax of workshopctl has changed slightly. Check READMEs
for details.
