Docker-airflow: Dockerfile not consistent with latest image?

[hxu-lift]

When I use image from docker hub: puckel/docker-airflow:1.10.2 and docker-compose-LocalExecutor.yml for docker-compose up I got no issue running the airflow web server.

However when I try to build image from the Dockerfile and run the same docker-compose file, I got this:

Is there some configurations I am missing?

See #342

Edit the Dockerfile to change the airflow version to 1.10.1 or add that dependency.

Install library libpq5 after buildDeps as it is getting removed later:

&& apt-get purge --auto-remove -yqq $buildDeps \

[bryan3189]

@shreyapatni Can you provide an example of where you are installing libpq5? Thanks!

[thierryturpin]

It's because of the psycopg2 release... Created #370 for it.
