The changes introduces in #3256 require at least rkt 1.27.0 because of
a bug in the JSON output of `rkt status` in previous versions.
Here we upgrade all references to rkt's minimum version, and also make
travis and vagrant use this version when running tests.
Finally we add a CHANGELOG notice.
This commit reworks the Vagrantfile for Nomad in order to support
straightforward testing on more than one operating system, whilst
retaining the ability to stand up a test cluster running Ubuntu.
The following changes are made:
- Scripts have been extracted from the Vagrantfile into their own shell
script files, in order that editors lint them.
- All scripts have been edited to lint with no warnings or errors for
their respective shells.
- Scripts are named according to the operating system and privilege
level which they run. We prefer to run a whole shell script as root
versus prefixing (essentially) every command with `sudo` or an
equivalent.
- The Linux development box has been separated from the test cluster,
removing some of the more gnarly (and less portable) logic. The Linux
development box is still primary and autostarts.
- A FreeBSD target has been added. The base box works for both
Virtualbox and VMWare Fusion.
- A target is added to the GNUmakefile to stand up a test cluster, using
the default provider, or overriding the provider by setting the PROVIDER
variable in make:
- `make testcluster`
- `make testcluster PROVIDER=vmware_fusion`
- Machines in the test cluster have Avahi configured for zeroconf
discovery. Each machine can ping each other machine at `hostname.local`
- for example `nomad-server02.local`, `nomad-client03.local`.
