Can someone help me sort the below issue out? I am trying to spin up an ubuntu image with the below Dockerfile

FROM ubuntu:16.04

RUN apt-get -q -y update && \
    apt-get -q -y upgrade && \
    apt-get -q -y install ssh
RUN groupadd remote_user
RUN useradd -d /home/remote_user -ms /bin/bash -g remote_user -G remote_user -p 123 123 && \
    mkdir /home/remote_user/.ssh && \
    chmod 700 /home/remote_user/.ssh
RUN ls
COPY remote-key.pub /home/remote_user/.ssh/authorized_kyes
RUN ls /home/
RUN chown -R remote_user:remote_user /home/remote_user/.ssh/ && \
    chmod 600 /home/remote_user/.ssh/authorized_keys
RUN /usr/sbin/sshd-keygen
CMD /usr/sbin/sshd -D

When building using docker-compose build, I am getting invalid user: remote_user:remote_user See the some of the output of the build:

Step 8/10 : RUN chown -R remote_user:remote_user /home/remote_user/.ssh/ && 
chmod 600 /home/remote_user/.ssh/authorized_keys
 ---> Running in 7c161db2565e
chown: invalid user: 'remote_user:remote_user'
ERROR: Service 'remote_host' failed to build: The command '/bin/sh -c chown -R remote_user:remote_user /home/remote_user/.ssh/ &&     chmod 600 /home/remote_user/.ssh/authorized_keys' returned a non-zero code: 1

Thanks in advances!

chown docker

Your useradd command is wrong as you are creating an user named 123. The last argument of the command is the username so you should use remote_user instead.
