Dockerfile没有高亮怎么办

整三个文件即可解决

/usr/share/vim/vimfiles/doc/dockerfile.txt

/usr/share/vim/vimfiles/ftdetect/dockerfile.vim

/usr/share/vim/vimfiles/syntax/dockerfile.vim

创建 /usr/share/vim/vimfiles/doc/dockerfile.txt 文件

cat > /usr/share/vim/vimfiles/doc/dockerfile.txt << EOF

创建 /usr/share/vim/vimfiles/ftdetect/dockerfile.vim 文件

cat > /usr/share/vim/vimfiles/ftdetect/dockerfile.vim << EOF
    au BufNewFile,BufRead [Dd]ockerfile,Dockerfile.*,*.Dockerfile set filetype=dockerfile

创建 /usr/share/vim/vimfiles/syntax/dockerfile.vim 文件

    " since @SH will handle "\" as part of the same line automatically, this "just works" for line continuation too, but with the caveat that it will highlight "RUN echo '" followed by a newline as if it were a block because the "'" is shell line continuation...  not sure how to fix that just yet (TODO)

然后再次打开 Dockerfile ，可以看到高亮有了
