ERROR: Dockerfile parse error line 66: Unknown flag: mount
why?How to solve it?
The docker files uses the buildkit format, you would need to enable experimental flag in docker and then run the following command
export DOCKER_BUILDKIT=1
docker-compose.....
Do let me know if you still face issue.
Reference : https://docs.docker.com/develop/develop-images/build_enhancements/
According to the above steps, this problem still exists.
[root]# docker version -f '{{.Server.Experimental}}'
true
[root]# export DOCKER_BUILDKIT=1
[root]# docker-compose build
tcpdump uses an image, skipping
softphone uses an image, skipping

Looks like docker-compose build doesn't yet work with build-kit based docker files. It throws the same error for me.
This sequence of commands works for me
export DOCKER_BUILDKIT=1
docker build -f Dockerfile.orkaudio -t orkaudio .
docker-compose runThis should run on your system.
Alternatively, if it still throws error, you can pull in prebuild image from docker hub
docker run --net=host -v /var/log/orkaudio:/var/log/orkaudio -it voiceip/orkaudio
Do let me know if either of the above steps works for you.
Thank you very much, follow these steps to start the container normally
export DOCKER_BUILDKIT=1
docker build -f Dockerfile.orkaudio -t orkaudio .
docker run -itd --net=host --restart=always --privileged=true --name orkaudio orkaudio
