This is going to be VERY fragile, but does work for simple yaml.  Overall it is last resort, but can get you out of a jam.

<pre>
{
  printf 'host_entries:\n'
  while read -r -a line; do
    [[ ${line[0]} ]] || continue             # skip blank lines
    [[ ${line[0]} = "#"* ]] && continue      # skip comments
    [[ ${line[0]} = 127.0.0.1 ]] && continue # skip localhost

    set -- "${line[@]}" # assign words read from line to current argument list
    ip=$1; shift        # assign first word from line to ip
    for name; do        # iterate over other words, treating them as names
      printf "  %s:\n    ip: '%s'\n" "$name" "$ip"
    done
  done
} </etc/hosts >yourfile.yaml

This is WRONG but works for this simple case.  Creating a YML file from a vars file should be less problematic however since it is key=value

This will allow creating a YML file with bash substitutions.
example is for bosh!!
