code-4.1 "fork/exec /proc/self/exe: no such file or directory" #80

  1. 在container_process.go中不添加 "cmd.Dir = "/root/busybox" 这行，不会报/proc/self/exe 文件不存在。 报错信息是：{"level":"error","msg":"Exec loop path error exec: \"sh\": executable file not found in $PATH","time":"2021-05-27T14:04:15Z"} {"level":"fatal","msg":"exec: \"sh\": executable file not found in $PATH","time":"2021-05-27T14:04:15Z"}

  2. 在container_process.go中添加 "cmd.Dir = "/root/busybox"这行后，报错"fork/exec /proc/self/exe: no such file or directory" （mount确认已经绑定过 #mount: /proc: proc already mounted on /proc.）

你要把解压的busybox放到/root下，你新挂载的文件系统没有 sh 命令；
