Patient Data Warehouse Navigator

Supported tag(s)

• 3.0.0 contains a MariaDB⁠ backed PaDaWaN and is based on this Docker image

How to use this image

Start a PaDaWaN instance

To start a PaDaWaN instance, you have to enter

docker run --name padawan -p port:8080 uniwue/padawan:tag

where port is your local port under which PaDaWaN should become accessible and tag is one of the tags listed above.

Manage the created PaDaWaN instance

• After creating a PaDaWaN instance with the above docker run command, you could stop it by entering docker stop padawan .
• If you want to start an already created instance, you have to enter docker start padawan .
• By entering the command docker rm padawan the PaDaWaN instance could be deleted.
• To create multiple instances on a single machine, you have to replace padawan in all the above docker commands with any other name.

Use a started PaDaWaN instance

After running the above command wait until you see PaDaWaN has finished starting printed to the console before start using PaDaWaN.

To use PaDaWaN, a web-based GUI for querying the data warehouse is available at

http://localhost:port/PadawanWebService/

By default, you could log in using the username demo and the password demouser.

(port has to be replaced with the port specified in the initial run command.)

Environment variables

The following environment variables can be set to adjust PaDaWaN's configuration:

• PADAWAN_LOAD_DEMO_DATA could be set to either true or false to indicate, whether a dataset for demonstration purposes should be generated and imported into PaDaWaN. This variable defaults to true.
• PADAWAN_NUM_OF_PATIENTS sets the number of patients to be generated, if PADAWAN_LOAD_DEMO_DATA is set to true. This variable defaults to 10.
• PADAWAN_TEST_USER specifies the username of the initial user being created to log in to PaDaWaN. The default username is demo.
• PADAWAN_TEST_PASSWORD sets the password for the initial PaDaWaN user. The default value is demouser.
• PADAWAN_TEST_GROUP is being used to specify the name of the initial group, that should be created. This group has full administrative access to PaDaWaN, and the above-described initial user will be added to this group. The default group name is DemoGroup.
• PADAWAN_SOLR_RAM specifies the amount of RAM the Solr server inside the container should use. Because Solr uses two separate shards, the specified amount of RAM is necessary twice. The default value is 1g.

Please note that all these environment variables are only considered during the first startup of a PaDaWaN instance. Setting or adjusting them later for the same instance won't have any effect.

Database access

If you need direct access to the database used by the PaDaWaN instance, you will first have to expose its port during the initial creation of the instance by adding -p localDBPort:3306 to the above docker run command. Replace localDBPort with your local port where the database should become accessible.

The database can then be accessed with the following login credentials:

• Name of the database: misbased
• Username: misbasedUser
• Password: Passw0rd!

(Please note that these database credentials can't (and may not) be changed.)

The image also contains an installation of Adminer⁠. To access it, you have to add -p localApachePort:80 to the above docker run command and replace localApachePort with your local port where Adminer should become accessible. After that you will be able to access it at http://localhost:localApachePort/adminer.php using the database credentials listed above.

Solr access

PaDaWaN uses a Solr⁠ index for an increase of the query processing time. If you would like to access this index directly, you have to add -p localSolrPort:8983 to the initial docker run command. After that you will be able to access it at http://localhost:localSolrPort/solr, where localSolrPort has to be replaced with your local port where Solr should become accessible.

The Solr index can then be accessed with the following login credentials:

• Username: admin
• Password: Passw0rd

(Please note that these Solr credentials can't (and may not) be changed.)
