- Now using vagrant box wesmcclure/ubuntu1404-docker, not boxcutter. The boxcutter box was removed after this course was published.
- Clone this repository locally
- Tested with Vagrant 1.8.4 and Consul 0.6.4
- Glossary: https://gist.github.com/g0t4/10c82f7ffd8a3f0cbd3980593259b7a8
See SETUP_MAC.sh
- This repo forces LF line endings on checkout, see
.gitattributes - If you want to edit files, install an http://editorconfig.org/#download plugin for whatever IDE you use to edit code.
- This will ensure that files you create/modify have *nix LF endings and not CRLF.
- Otherwise, you'll have random trouble with scripts you create and try to run on *nix VMs.
- I have already added a
.editorconfigfile to this project
There's a Vagrantfile in this repository that spins up the simulated environment.
If you want to run everything, there's 14 VMs in total, you need:
- 10 GB of free memory
- 4+ core CPU
- 20 GB of free disk space
If you have less than this, scale back the number of VMs you spin up, in the Vagrantfile, change the range (1..3) to (1..2) or (1..1). If you update the consul-server count, update provision/cs-consul.d/server.json and set bootstrap_expect accordingly.
