Setting Up Evaluators for a Kubernetes Environment

When deploying the Autoscaling Service to Kubernetes, you must create an image with the rep-evaluator executable and solver application executables. This image should be used when configuring the autoscaler's available applications.

On the Ansys Customer Portal site, go to the Downloads: Platform Components page.
(To navigate to this page on the Ansys Customer Portal site, select Downloads > Current Release, then select Platform Components in the navigation pane.)

Download the applicable file:

OS	Select Product	File Downloaded
Rocky Linux 8.10 for Ansys by CIQ, CentOS 7	hps-evaluator (Centos7)	rep-evaluator-centos7.tgz
CentOS 8 or later, Ubuntu (versions other than 20.04)	hps-evaluator (default)	rep-evaluator-default.tgz
Ubuntu 20.04	hps-evaluator (unbuntu20_04)	rep-evaluator-ubuntu20_04.tgz

Use the gunzip command to unpack the tgz file.
```
gunzip <filename>.tgz
```
Use tar -xvf to extract the contents of the tar file.
```
tar -xvf <filename>.tar
```
Change (cd) to the extracted folder. This folder contains the rep-evaluator executable.
Go the Ansys Customer Portal and download the executable file of the solver application.
Create an image and copy the rep-evaluator executable and solver application executable.

Ensure that the image entrypoint.sh file contains the following instructions:

ANSYS_EVAL_LOGIN=${ANSYS_EVAL_LOGIN:-1}
ANSYS_EVAL_BASE_OPTS="--plugin-path=<< plugin path >>"
ANSYS_EVAL_LOGIN_OPTS=""

if [[ $ANSYS_EVAL_LOGIN -ge 1 ]]; then
    echo "Logging in ..."
    << path to rep-evaluator executable >> $ANSYS_EVAL_BASE_OPTS login $ANSYS_EVAL_LOGIN_OPTS
fi

echo "Starting evaluator ..."
echo "Options: $ANSYS_EVAL_BASE_OPTS $*"
 << path to rep-evaluator executable >> $ANSYS_EVAL_BASE_OPTS $*
