我试图建立一个Clojure（Script）应用程序，使其与here中所述的nREPL实例一起在Docker内部运行，我也想在容器内部运行。我使用lein new reagent reagent-docker设置了项目，并且已经使应用程序和REPL服务器都在容器中运行。此时，我唯一的问题是让编辑器（或主机上的任何内容）连接到REPL服务器。当我尝试时，它只会显示“对等方重置连接”。
我可以docker exec -it <container> bash进入容器，并直接从REPL服务器（即curl 127.0.0.1:7002）获得空200响应。但是，当我在主机上尝试相同操作时，即使转发端口，也会收到“连接重置”错误。
要运行容器，我正在做
docker run -it -v "$(pwd)":/app -p 3449:3449 -p 7002:7002 -p 8800:8800 --env port=8800 dclj:latest
并运行REPL：
docker exec -it 61a58e2bc284 lein figwheel
此命令成功运行REPL，我只是无法从主机连接到它。我可以在其他端口上连接到localhost-它可以按照您的期望将应用程序提供给浏览器。
我什至可以看到它转发了所有端口：
$ docker ps | grep dclj
