Start sshd automatically with docker container

Question

Given:

• container based on ubuntu:13.10
• installed ssh (via apt-get install ssh)

Problem: each when I start container I hav

Answer 1

Well, I used the following command to solve that

docker run -i -t  mycentos6 /bin/bash -c '/etc/init.d/sshd start && /bin/bash'

Answer 2

You can start ssh server when starting your container probably. Something like this:

docker run ubuntu /usr/sbin/sshd -D

Check out this official tutorial.

Answer 3

This is quite an old question, but for the sake of others finding it, I think the correct way to do it would follow docker's instructions to dockerizing the ssh service.

And in correlation to the specific question, the following lines added at the end of the dockerfile will achieve what you were looking for:

EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

Answer 4

This is what I did:

FROM nginx

# install gosu
# seealso:
# https://docs.docker.com/develop/develop-images/dockerfile_best-practices/
# https://github.com/tianon/gosu/blob/master/INSTALL.md
# https://github.com/tianon/gosu
RUN set -eux; \
    apt-get update; \
    apt-get install -y gosu; \
    rm -rf /var/lib/apt/lists/*; \
# verify that the binary works
    gosu nobody true

ENV myenv='default'

RUN apt-get update && apt-get install -y openssh-server
RUN mkdir /var/run/sshd

COPY entrypoint.sh /entrypoint.sh

ENV AIRFLOW_HOME=/usr/local/airflow
RUN mkdir $AIRFLOW_HOME
RUN groupadd --gid 8080 airflow
RUN useradd --uid 8080 --gid 8080 -ms /bin/bash -d $AIRFLOW_HOME airflow
RUN echo 'airflow:mypass' | chpasswd


EXPOSE 22
CMD ["/entrypoint.sh"]

Inside entrypoint.sh:

echo "starting ssh as root"
gosu root service ssh start &
#gosu root /usr/sbin/sshd -D &

echo "starting tail user"
exec gosu airflow tail -f /dev/null

Answer 5

Just try:

ENTRYPOINT service ssh restart && bash

in your dockerfile, it works fun for me!
