  • or from https://github.com/pydap/pydap
• netCDF4
• coards
• gsw
• optionally handlers from https://github.com/pydap

the requirements can e.g. be installed with:

sudo apt install python3-dev
sudo apt install libnetcdf-dev
virtualenv -p /usr/bin/python3.5 pydap_env
source pydap_env/bin/activate
pip install numpy netCDF4 coards gsw flask
pip install git+https://github.com/NiklasPhabian/pydap
pip install git+https://github.com/NiklasPhabian/pydap.handlers.netcdf

Running occur_pydap

  python occur_pydap/app/main.py

Dockerization

The application can be dockerzied using the included Dockerfile.

Build docker image: docker build . -t occur_pydap

The built docker image is also available at: https://hub.docker.com/r/griessbaum/occur_pydap/

Start docker instance: docker run -p 8080:80 -v ~/occur_pydap/data:/data occur_pydap

In this command, we are mapping the container's port 80 to the host's port 8080 and bind mount the folder ~/occur_pydap/data to the container's folder /data.

environment variables:

• APP_DEBUG (default: False)
• APP_PATH (default: ~/occur_pydap/data)
• APP_HOST (default: 0.0.0.0)
• APP_PORT (default: 80)

Container DNS configuration

As of Ubuntu 16.04 and Docker 1.12.6, containers will fail to set up a DNS server in networks that block external DNS servers. The issue is described in: moby/moby#23910 and resolved by:

echo {"dns": ["172.17.0.1"]}  > /etc/docker/daemon.json
echo listen-address=172.17.0.1 > /etc/NetworkManager/dnsmasq.d/docker-bridge.conf
