it seems like the "ps" command is no longer part of the image: C:\>docker exec -it 815d7894e551 ps -aux OCI runtime exec failed: exec failed: unable to start container process: exec: "ps": executable file not found in $PATH: unknown
It just means that command/binary `ls` is not available. You can run any other command like "df" to make sure a common is executed inside the docker container.
I am also getting the same error. "OCI runtime exec failed: exec failed: unable to start container process: exec: "ps": executable file not found in $PATH: unknown"
