Setting PYTHONPATH in Ubuntu 16.04 for a Docker image to run properly

I have a docker image that is running a gunicorn process, but everytime it runs I get the error ImportError: No module named ‘crm’. So I am following this SO post to solve this issue. However, when I run ENTRYPOINT [“PYTHONPATH=`pwd`/..”, “/usr/local/bin/gunicorn”, “web_interface:app”, “-w 4”, “-t 90”, “–log-level=debug”, “-b”, “–reload”] the container spits back […]

Docker on mac: How to auto restart daemon processes after a machine reboot?

How does one auto-restart a docker-compose process after the machine reboots? For non-docker processes, I use supervisord on Ubuntu. Is there an equivalent on mac for docker-compose? What about on Ubuntu?

Dokku/Docker, how to access file in file system of running container?

Previously, to access a file in a running dokku instance I would run: docker ps to get the container ID followed by ls /var/lib/docker/aufs/diff/<container-id>/app/… note: I’m just using ‘ls’ as an example command. I ultimately want to reference a particular file. This must have changed, as the container ID is no longer accessible via this […]

Uninstall applications within docker?

I am using docker to build and run a set of services. For one of these, I need to install a number of packages in order to complete an internal (gulp.js) build process, but they aren’t necessary in the final docker image.
