Docker: How to use bash with an Alpine based docker image?（6个答案）
28天前关闭。
我正在尝试使用Docker运行shell脚本。以下是我的Docker文件：

FROM alpine
COPY . .
RUN chmod +x ./scripts/sanity-checks.sh
ENTRYPOINT ["./scripts/sanity-checks.sh"]

但是，当我尝试运行它时，我得到以下错误：

./scripts/sanity-checks.sh: scripts/util.sh: line 225: syntax error: unexpected "(" (expecting "}")

这是我在www.example.com上看到的内容util.sh:

...  
# delete the lines between and including 2 comment lines, or the comment lines themselves only
    delete_lines_for_file() {
      file_name=$1
      delete_string_start=$2
      delete_string_end=$3
      delete_comments_only=$4
      # find the start and end lines where we want to delete blocks of code
      line_num_start=$(grep -n "$delete_string_start" $file_name | awk -F  ":" '{print $1}')
      line_num_end=$(grep -n "$delete_string_end" $file_name | awk -F  ":" '{print $1}')
      line_start_arr=($line_num_start) ### LINE 225 ###
...

当我在不使用Docker的情况下运行脚本时，它工作正常。知道是什么原因导致了这个错误吗？
