以 EOF 结尾时出现 Bash 错误

Question

如果这条信息在这里不太合适，我提前表示歉意，但我相信这是一个好地方。

当我执行 bash 脚本时出现这个奇怪的错误：

./cluster_bootstrap.sh 
./cluster_bootstrap.sh: line 15: $'\r': command not found
./cluster_bootstrap.sh: line 91: warning: here-document at line 37 delimited by end-of-file (wanted `EOF')
./cluster_bootstrap.sh: line 92: syntax error: unexpected end of file

同时，当我将脚本复制粘贴到我的 shell 中时，一切似乎都正确。您对这种奇怪的行为有什么看法？

PS：这是我的脚本：
