Wrong indentation when editing Yaml in Vim

Question

Vim does not seem to correctly react at a dash symbol in YAML files therefore breaking the format.

For example I have a block which should look like this:

You can use this autocommand to make Vim properly indent YAML files (put it to your .vimrc):

" Fix auto-indentation for YAML files
augroup yaml_fix
    autocmd!
    autocmd FileType yaml setlocal ts=2 sts=2 sw=2 expandtab indentkeys-=0# indentkeys-=<:>
augroup END

Basically, for YAML file it instructs Vim to:

• Use 2 spaces for indentation.
• Use spaces instead of tabs.
• Skip re-indenting lines after inserting a comment character (#) at the beginning of a line, or a colon.
