9. Hands-On
Hands-On Sensor Web Open Source Software!
In order to get the most easy jump-start on Sensor Web software, we have developed a set of Docker containers. You will require Docker running on your machine in order to use the following examples. Instructions for all supported platform are available at:
52°North Sensor Web Docker Containers
This section provides a brief overview on the available Docker images for the Sensor Web, created and maintained by 52°North:
mdillon provides docker images of PostgreSQL with PostGIS extensions and templates installed. We have based our example databases on these images.
SOS Setup
The 52north/sos-configured docker image consists of a pre-configured SOS instance running in a Tomcat container. It has the following settings:
- Database connection: PostgreSQL on
postgres:5432
with credentialspostgres:postgres
(the DB is running in a DNS named (postgres
) docker container) - Administrator account with credentials
admin:admin
- Transactional operations enabled
The 52north/sos docker image is a simple instance of a non-configured SOS. This image requires the installation procedure to be executed.
Using an Empty Database
For this example, we use the non-configured 52north/sos docker image. Run the following docker commands:
- Start the postgres container:
docker run -e "POSTGRES_DB=sos" --name sos-empty-postgres -p 5432:5432 mdillon/postgis:9.5
- Run the sos docker image:
docker run --link sos-empty-postgres:postgres -p 8080:8080 52north/sos:4.3.8
Alternatively, you can use the following docker-compose.yml file (run with
docker-compose build && docker-compose up
):
version: '2'
services:
postgres-db-empty:
image: mdillon/postgis:9.5
ports:
- 5432:5432
expose:
- 5432
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgres
- POSTGRES_DB=sos
sos-service:
image: 52north/sos:4.3.8
ports:
- 8080:8080
links:
- postgres-db-empty:postgres
Now, access http://localhost:8080/52n-sos-webapp. The landing page will tell you to execute the installation procedure. Follow this guided procedure. In particular, apply the following properties:
- as the Datasource select
PostgreSQL/PostGIS
- in the Database Configuration section, make sure to set the
Host to
postgres
You will have your SOS running in a few seconds.
Using a Pre-filled Database
For this example, we use the pre-configured 52north/sos-configured docker image. A database with some sample data is available as the 52north/sos-weather-postgres docker image. Execute the following docker commands:
- Start the postgres container:
docker run --name sos-weather-postgres -p 5432:5432 52north/sos-weather-postgres:4.3.8
- Run the sos-configured docker image:
docker run --link sos-weather-postgres:postgres -p 8080:8080 52north/sos-configured:4.3.8
Alternatively, you can use the following docker-compose.yml file (run with
docker-compose build && docker-compose up
):
version: '2'
services:
sos-weather-postgres:
image: 52north/sos-weather-postgres:4.3.8
ports:
- 5432:5432
expose:
- 5432
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgres
- POSTGRES_DB=sos
sos-service:
image: 52north/sos-configured:4.3.8
ports:
- 8080:8080
links:
- sos-weather-postgres:postgres
The SOS is now up and running at http://localhost:8080/52n-sos-webapp.
REST API Setup
Both the 52north/sos and the 52north/sos-configured image come with the Series REST API bundled in the webapp. You can access the API at: http://localhost:8080/52n-sos-webapp/api/v1/.
Helgoland (JS Client) Setup
The images also contain the Helgoland JavaScript client. You can access the client at: http://localhost:8080/52n-sos-webapp/static/client/helgoland/#/map
More Example Data
SOS Solar Irradiance Example Database
This database contains in-situ data for Solar Irrandiance as well as data derived by several models. The data is located at a station in Signes, France, and contains data for the first two weeks of September 2015.
The provided data is an excerpt of the database provided on http://webservice-energy.org/. This platform is an effort carried out by the center Observation, Impacts, Energy (O.I.E.) of MINES ParisTech / ARMINES and also from the SoDa Team toward the Energy and Environmental Community.
Access
The database is available as a docker container:
For usage, adjust the above docker commands (or docker-compose.yml
) with the corresponding image:
52north/sos-solar-postgres:4.3.8
.
