My container creates fifo pipe in the bind mounted dir but container when reads or writes to this pipe, the host cant recieve it or vice versa. with similar permissions to create or open pipe works for comunication within host and within containner. But it does not work in between host and containner.
The pipe is created and reads/writes in cpp program within containeer. Pipe created with both 666 and 777 permisssions and opened with O_RDWR. Simmilar cpp programs reads/writes in the host. Again these program works fine within containner and within host the problem happens only in host communication.
docker run -it --name broken-container -v /tmp:/app2 cppdocker
