Question

Hi all I looked for some keywords in the history but I didn t find my answer I need some customisation on top of hydra docker image The base image that I am using is `oryd hydra v1 10 7` On top of it I add some config files and install netcat on top of it for a custom startup script Whenever I am executing any command by `RUN` in my dockerfile I am getting an error when building the docker image `executor failed running bin sh c apk add netcat openbsd unable to find user 1000 invalid argument` Any help is appreciated thank you
