[gannebamm]

changed the docker-compose.yml to use geonode/postgis:10
See my PR#1 GeoNode/postgis-docker#1

@gannebamm we need to have the image published on the docker hub before having this merged. Also can you please check why Travis is failing?

@francbartoli Travis is failing for any PR

[gannebamm]

@francbartoli I don´t know why travis is failing to build this image. @giohappy Meant the travis pipeline has some hiccups?

I have built it successfully on my desktop and used it successfully in the docker-compose geonode setup. I spawned the stack, created a new user and uploaded a shapefile. All of those went without issues.
I did not run any tests, though. I should be able to run them in the django4geonode container, shouldn´t I?

@francbartoli @giohappy
I have looked int the Travis logs:

---

6961.1 errored

The job exceeded the maximum time limit for jobs, and has been terminated.

6961.3 errored

The job exceeded the maximum time limit for jobs, and has been terminated.

Both do not seem to be related to my PR but some memory issues or timeouts.
