How can I install other packages to this image?

[MauricioLins]

I am trying to install ssh through the docker compose calling the dockerfile, simple like that:

FROM puckel/docker-airflow

RUN apt-get install -y net-tools
RUN apt-get install -y openssh-server apache2 supervisor
RUN mkdir -p /var/lock/apache2 /var/run/apache2 /var/run/sshd /var/log/supervisor
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf

And I am getting this error:

E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

Even if I try manually logging as root and run these commands it does not work.

I am thinking is better to get the airflow original's image and configure everything.

Any thoughts about it?

This looks like you're going to try to put an apache server in front of the airflow webserver on the same container. If that is the case, I would suggest using the httpd image as a separate micro-service.
