我正在尝试使用此处提供的 Dockerfile，并在构建时docker build .收到第 69 行（RUN createuser -s projop）上的错误，该错误报告：
Step 15/27 : RUN /usr/bin/pg_ctl -D "/var/lib/pgsql/data" start
---> Using cache
---> ce049ebe4ff5
Step 16/27 : RUN sleep 60
---> Using cache
---> bf7bac638da6
Step 17/27 : RUN createuser -s projop # database user "projop" with admin rights
---> Running in 700e6e618060
createuser: could not connect to database postgres: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
我最初的想法是 postgres 服务器之前没有足够的时间从线路启动，所以我将 sleep 命令延长到 60 秒，但我仍然遇到同样的错误。
在使用docker run -it bf7bac638da6 bash. 在这个 bash 会话中，我尝试手动运行createuser -s projop给出相同错误的行。
但是，如果我重新运行该命令/usr/bin/pg_ctl -D "/var/lib/pgsql/data" start，那么createuser -s projop它将起作用。
这很奇怪，因为初始启动命令似乎没有生效。有什么想法可能在这里发生吗？
