I'm using Laravel Sail and have published the Dockerfile (so I can edit it manually). The reason being that I need to use an OpenSSH server on the container itself for a program I'm using.

I am able to install OpenSSH by adding && apt-get install -y openssh-server to the packages section and configure it with the following:

RUN mkdir /var/run/sshd
RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
EXPOSE 22

The issue though is that it does not start when the container starts.

According to this answer you can add an ENTRYPOINT as follows:

ENTRYPOINT service ssh restart && bash

However you can only have one ENTRYPOINT and Laravel Sail has this by default:

ENTRYPOINT ["start-container"]

I have tried the following:

  • add /usr/sbin/sshd to the start-container script - it didn't start
  • add CMD ["/usr/sbin/sshd", "-D"] into the Dockerfile as per this answer - it gave a permission denied error when starting the container

As the php container uses supervisor you can add another application to the config. Reference for the config can be found here.

Example

ssh.ini:
[program:sshd]
command=/usr/sbin/sshd -D
