DTR Worker capacityMap Updater

Purpose

This script will list, update, and reset DTR's capacityMap mirror, scan, and scanCheck based on the number of cores per DTR replica (i.e. DTR Worker node).

How to Run

You may build a Docker image and then run the image wherever you so chose. Or, you can run the bash script directly.

How to Run: Docker Image

Clone this repo
Build the Docker image:

docker image build -t dtr_worker:1.0 -f ./Dockerfile .
Run the Docker image:

read -sp 'Password: ' password; docker container run -it --rm -e ucp_server="ucp.example.com" -e dtr_server="dtr.example.com" -e username="admin-user" -e password=${password} dtr_worker:1.0 <command>

How to Run: bash script

Run the script:

username=admin-user; \
ucp_server=ucp.example.com; \
dtr_server=dtr.example.com; \
read -sp 'Password: ' password; ./dtr_worker.sh <command>

Usage

clemenko:clemenko Desktop $ ./dtr_worker.sh usage
 Usage: ./dtr_worker.sh {list  - list current map |  update  - update map to half core |  reset  - reset values to 1}
