Apparently this is a known issue.
Here I'm documenting some specifics of the fix that weren't clear from the stackoverflow answer. Not totally sure if I did the "right" thing but it works.
1) Download https://raw.githubusercontent.com/stephpy/vim-yaml/master/after/syntax/yaml.vim to ~/.vim
2) Put "au BufNewFile,BufRead *.yaml,*.yml so ~/.vim/yaml.vim" at the top of ~/.vimrc
You should be good to go.
