Deploying Geoserver

Enabling geoserver will add these 3 extractors

• ncsa.geotiff.preview, "geotiff preview extractor takes .tif input file to communicate with GeoServer to retrieve WMS metadata"

• ncsa.geotiff.metadata "Extractor to perform Geotiff."
  

• ncsa.geoshp.preview "gepshp extractor takes .zip input file to communicate with geoserver to retrieve WMS metadata"

In order to do this, the docker-compose.yml file should be modified in the following way 

# Geoserver application geoserver:
image: clowder/geoserver:${VERSION:-latest} networks:
      - clowder
    ports:
      - 8080:8080
    volumes:
- geoserver:/data_dir restart: unless-stopped
# deploy:
# # # # # # #
mode: replicated replicas: 1 placement:
constraints:
- node.role == manager
restart_policy: condition: any

The location of the actual geoserver volume on the server is specified in the docker-compose.override.yml file:

geoserver: driver_opts:
type: none
o: bind
device: /clowder/data/geoserver

Geoserver service configuration

The geoserver extractor is in the docker-compose-extractors.yml file.

The default credentials for Geoserver isadmin/geoserver So, once the docker container starts, go to the geoserver service which is running on:http://hos tname.dept.illinois.edu:8080/geoserver/web and create a new admin user, and reset the password for the default admin account, and then disable the default admin account.

This interface is running over http, not https, I havent figured out how to make it run over https yet, so dont login/change passwords very much to try to minimize how much the password is passed around in clear text.

Then clickthe Users/Groups tab, and from here you can create new users and add them to the admin group. Note: You do not need to add the GROUP_ADMIN Role, the default admin does not even have that.

Now you can configure the extractor with the user account and password to run as. In the above example I created a "clowder_user" and then I will put that account in the following envioronment options below:

- GEOSERVER_USERNAME=clowder_user
- GEOSERVER_PASSWORD=SETADIFFERENTPASSWORD! - GEOSERVER_USER=clowder_user

If you ever need to reset the admin password, you can bring down the docker stack, then rename the directory that the clowder/geoserver volume points to, then start the container and then the geoserver service will be set to all the defaults.

Initially I tried to get the extractor to work with a non-admin account, and I don't think it does, so renaming and adding a different password is a good idea.

Note: If the password includes a $ it will generate an error when you bring up the stack, so if the password has a $, you will need to escape the $ with an additional $. So in the below example the real password is actually SETADIFFERENT$PASSWORD!
