Install from GitHub

Check out code from the chickadee GitHub repo and start the installation:

$ git clone https://github.com/pacificclimate/chickadee.git
$ cd chickadee

Create Python environment named venv:

$ python3 -m venv venv
$ source venv/bin/activate

Start chickadee PyWPS service

After successful installation you can start the service using the chickadee command-line.

(venv)$ chickadee --help # show help
(venv)$ chickadee start  # start service with default configuration

# OR

(venv)$ chickadee start --daemon # start service as daemon
loading configuration
forked process id: 42

The deployed WPS service is by default available on:

http://localhost:5000/wps?service=WPS&version=1.0.0&request=GetCapabilities.

NOTE:: Remember the process ID (PID) so you can stop the service with kill PID.

You can find which process uses a given port using the following command (here for port 5000):

$ netstat -nlp | grep :5000

Check the log files for errors:

$ tail -f  pywps.log

… or do it the lazy way

You can also use the Makefile to start and stop the service:

$ make start
$ make status
$ tail -f pywps.log
$ make stop

Run chickadee as Docker container

You can also run chickadee as a Docker container.

$ docker-compose build
$ docker-compose up

chickadee will be available on port 8102.
