Docker-Networking

Testing networking between docker containers - Access to network resources using the DAP protocol.

This series of images includes four services:

This notebook shows the behaviour of internal docker networking when accessing services using the docker service name.

This docker environment starts 4 different services:

• apache: Apache web server
• hyrax: Hyrax OpenDAP service
• pydap: PyDAP OpenDAP service
• jupyter: Jupyter Notebook

Example data access

There are few example netcdf dataset in the volume directory under:

• /volumes/apache2/data

which are served by both Hyrax and PyDAP services using the OpenDAP protocol.

From outside the docker environment those resources are reachable using the "exposed" services:

• Apache: http://localhost/SN99938.nc
• PyDAP: http://localhost:9090/SN99938.nc
• Hyrax: http://localhost:8080/opendap/hyrax/SN99938.nc.nc4

From inside the docker environment those resources are (should be) reachable using the "internal service names":

• Apache: http://apache/SN99938.nc
• PyDAP: http://pydap/SN99938.nc
• Hyrax: http://hyrax:8080/opendap/hyrax/SN99938.nc.nc4

---

To start using this set of docker containers:

git clone https://github.com/epifanio/Docker-Networking
cd Docker-Networking
sudo docker-compose up

Tt will print out in the log an url for a jupyter notebook (it uses an access-token in the url) open that url in the browser and a jupyter notebook server will open.
