Locating and Downloading ATS Images

The steps to locate and download ATS Images are as follows:

1. The ATS Images are available on the OHC server. To download the ATS Images from OHC:
   1. Go to the URL, https://docs.oracle.com
   2. Navigate to Industries > Communications > Cloud Native Core
   3. Click the Automated Testing Suite (ATS) Images link to download the zip file.
   4. Unzip the Images folder to access all the ATS Images
2. The ocats-nrf directory has following files:
   • ocats-nrf-pkg-1.0.0.0.0.tgz
   • ocats-nrf-pkg-1.0.0.0.0-README.txt
3. The ocats-nrf-pkg-1.0.0.0.0-README.txt file contains all the information required for the package.
4. The ocats-nrf-pkg-1.0.0.0.0.tgz file has following images and charts packaged as tar files:

   ocats-nrf-pkg-1.0.0.0.0.tgz
   
         |
   
         |_ _ _ocats-nrf-pkg-1.0.0.0.0.tgz
   
         |        |_ _ _ _ _ _ ocats-nrf-1.0.0.tgz (Helm Charts)
   
         |        |_ _ _ _ _ _ ocats-nrf-images-1.0.0.tar (Docker Images)
   
         |        |_ _ _ _ _ _ Readme.txt
   
         |
   
         |_ _ _ocstub-pkg-1.0.0.0.0.tgz
   
                  |_ _ _ _ _ _ ocstub-1.0.0.tgz (Helm Charts)
   
                  |_ _ _ _ _ _ ocstub-python-images-1.0.0.tar (Docker Images)
   
                  |_ _ _ _ _ _ Readme.txt
   

5. The user can either copy the tar file, which contains the images to their k8s cluster or upload these images to their central repository.

Deploying ATS in K8s Cluster

The steps to deploy ATS in K8s Cluster are as follows:

1. Execute the command given below to extract tar file content.

   tar -xvf ocats-nrf-pkg-1.0.0.0.0.tgz

   The output of this command is:

   ocats-nrf-pkg-1.0.0.0.0.tgz

   ocstub-pkg-1.0.0.0.0.tgz

2. Execute the command given below to extract final helm charts and docker images of ATS.

   tar -xvf ocats-nrf-pkg-1.0.0.0.0.tgz

   The output of this command is:

   ocats-nrf-1.0.0.tgz

   ocats-nrf-images-1.0.0.tar

   Readme.txt

3. Execute the command given below to load the ATS image, 'ocats-nrf-images-1.0.0.tar' in your cluster and push to your registry.

   docker load -i <image_name_to_be_loaded>

   docker tag <loaded_image_name> <image_name_to_be_tagged>

   docker push <image_name_to_be_pushed>

   For example:

   docker load -i ocats-nrf-images-1.0.0.tar

   docker tag ocnrf-registry.us.oracle.com:5000/ocats-nrf:1.0.0 porsche-bastion-1:5000/ocats-nrf:1.0.0

   docker push porsche-bastion-1:5000/ocats-nrf:1.0.0

4. Execute the command given below to untar the helm charts, ocats-nrf-1.0.0.tgz.

   tar -xvf ocats-nrf-1.0.0.tgz

5. Update the image name and tag in the ocats-nrf/values.yaml file as required.

   For this, you need to open the values.yaml file and update the values of image.repository and image.tag.

6. Execute the command given below to deploy ATS using the updated helm charts after performing step 5.

   helm install <chart_directory> --name <release_name> --namespace <namespace_name> -f <custom_values_filename>

   For example: helm install ocats-nrf --name ocats --namespace ocnrf -f ocats-nrf/values.yaml

7. Execute the command given below to verify ATS deployment.

   helm status <release_name>

Deploying Stub Pod in K8s Cluster

The steps to deploy Stub Pod are as follows:

1. Execute the command given below to extract ocstub tar file content.

   tar -xvf ocstub-pkg-1.0.0.0.0.tgz

   The output of this command is:

   ocstub-1.0.0.tgz

   ocstub-python-images-1.0.0.tar

   Readme.txt

2. Execute the command given below to load the STUB image, 'ocstub-python-images-1.0.0.tar' in your cluster and push to your registry.

   docker load -i <image_name_to_be_loaded>

   docker tag <loaded_image_name> <image_name_to_be_tagged>

   docker push <image_name_to_be_pushed>

   For example:

   docker load -i ocstub-python-images-1.0.0.tar

   docker tag ocnrf-registry.us.oracle.com:5000/ocstub-python:1.0.0 porsche-bastion-1:5000/ocstub-python:1.0.0

   docker push porsche-bastion-1:5000/ocstub-python:1.0.0

3. Execute the command given below to untar the helm charts, ocstub-1.0.0.tgz.

   tar -xvf ocstub-1.0.0.tgz

4. Execute the command given below to update the image name and tag in the ocstub/values.yaml file as required.

   Open the values.yaml file and update the values of image.repository and image.tag

5. Execute the command given below to deploy Stub.

   helm install <chart_directory> --name <release_name> --namespace <namespace_name> -f <custom_values_filename>

   For example: helm install ocstub --name ocstub --namespace ocnrf -f ocstub/values.yaml

6. Execute the command given below to check the Stub deployment.

   helm status <release_name>

A sample screen showing how to check Stub HELM Release is given below:
