Demo with release binary

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

The ./cc-backend -init command creates a config.json with sensible defaults. The cluster configurations (fritz and alex) are embedded in the job archive you will download below — no manual cluster configuration is needed in config.json. The generated file should look similar to:

{
  "main": {
    "addr": "127.0.0.1:8080",
    "short-running-jobs-duration": 300,
    "resampling": {
      "minimum-points": 600,
      "trigger": 300,
      "resolutions": [240, 60]
    },
    "api-allowed-ips": ["*"],
    "emission-constant": 317
  },
  "cron": {
    "commit-job-worker": "1m",
    "duration-worker": "5m",
    "footprint-worker": "10m"
  },
  "archive": {
    "kind": "file",
    "path": "./var/job-archive"
  },
  "auth": {
    "jwts": {
      "max-age": "2000h"
    }
  }
}

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:

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

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.
