Demo with release binary

The demo setup with the release binary only works with a Linux system running on a x86-64 processor.

Grab the release binary at GitHub. The following description assumes you perform all tasks from your home folder. Extract the tar archive:

tar xzf cc-backend_Linux_x86_64.tar.gz

Create an empty folder and copy the binary cc-backend from the extracted archive folder to this folder:

mkdir ./demo

cp cc-backend ./demo

Change to the demo folder and run the following command to setup the required var directory, initialize the sqlite database, config.json and .env files:

./cc-backend -init

Open config.json in an editor of your choice to edit the existing clusters name and add a second cluster. Name the clusters fritz and alex. The file should look as below afterwards:

Download the demo job archive:

wget https://hpc-mover.rrze.uni-erlangen.de/HPC-Data/0x7b58aefb/eig7ahyo6fo2bais0ephuf2aitohv1ai/job-archive-demo.tar

Extract the job archive:

tar xf job-archive-demo.tar

Initialize the database using the data from the job archive and create the demo user:

./cc-backend -init-db -add-user demo:admin:demo -loglevel info

Start the web server:

./cc-backend -server -dev -loglevel info

Open a web browser and access http://localhost:8080. You should see the ClusterCockpit login page:

ClusterCockpit Login page

Enter demo for the Username and demo for the Password and press the Submit button. After that the ClusterCockpit index page should be displayed:

ClusterCockpit Index page

The demo user has the admin role and therefore can see all views.

For details about the features of the web interface have a look at the user guide.
