Motivation
Docker
Slide by Docker inventor & Docker, Inc. CTO Solomon Hykes, DockerCon 2014
https://www.docker.com/use-cases
Motivation: mainstream IT use cases Recommendation: Watch the DockerCon
keynote: “15 min. to fix a bug at new job”https://www.youtube.com/watch?list=PLkA60AVN3hh9

Open access
Open access to data
Open access to data and procedures
Reproducibility platforms (identification/citation/credit, viewing, and downloading)
Meta-publications (Nature, Nature Geosciences, Science, …)
Motivation: Open Science
https://openaccessbutton.org/
Missing for reproducibility of computational research: access to and archival of runtime environments
To cut to the chase...
Who of you can reproduce a scientific analysis conducted 5 years ago today?
Who of you is sure she can start a multi-service demonstrator of a research project that was finished today in 5 years?

Docker for Geospatial Sensor Webs
52°North Helgoland
$ docker run -p 80:8080 52north/helgoland
http://172.17.0.2:8080/#/
$ docker run -p 80:80 geocontainers/52n-helgoland
http://localhost/#/
Differences: BRANCH env var, nginx vs. node, git clone during build (Hub)

52°North SOS
Whole (!) Dockerfile based on Debian (unsimplified)
FROM tomcat:9WORKDIR /tmpRUN curl -L -o sos-bundle.zip http://../491-52n-sensorweb-sos-bundle-4-3-7RUN unzip -d sos-bundle sos-bundle.zipRUN cp sos-bundle/*.war $CATALINA_HOME/webapps/52n-sos-webapp.warRUN rm -r *
Command to run image based on Alpine
$ docker run --rm -p 80:8080 geocontainers/52n-sos-alpine# http://localhost/52n-sos-webapp/
docker-compose configuration (SOS + PostGIS DB)

Docker for Geospatial Sensor Webs
We need to catch up with mainstream ITCollaborate more effectively (prod/dev/research)
Spread software more easily and more DevOps friendly by bringing down requirements to 1 software and installation to 1 command
Quickly (re) create dev, demo, test, production (customer!) environments
Effective deployment of the latest software thin your own infrastructure or in the cloud

Docker for Geospatial Sensor Webs - How?
1. Use it! You admins won’t mind. Your work will be easier.
2. Provide and share (!) images and docker-compose files for popular services on Docker Hub (52°North is getting started)https://github.com/Geonovum/smartemission/tree/master/docker/sos52n
3. Keep in mind during implementation (e.g. configurability)
4. Add getting services cloud ready + scalable prominently to all funding efforts
5. Experiment with desktop apps
