@guy7711 can you also share which version of CSI Driver that you are trying to install ?

[guy7711]

im installing v2.0.0, now trying with v2.1.0 - though im unable to run docker pull for this version, it only works with "latest" tag

docker pull dellemc/csi-unity:v2.1.0 Error response from daemon: manifest for dellemc/csi-unity:v2.1.0 not found: manifest unknown: manifest unknown

@guy7711 : v2.0.0 works with latest tag and v2.1.0 works with nightly tag.

[prablr79]

@guy7711 our suggestion to use Released build tag which v2.0.0 and v2.1.0 still under development.

[prablr79]

@guy7711 this tag is not released yet docker pull dellemc/csi-unity:v2.1.0. hence closing this bug.

[guy7711]

@guy7711 this tag is not released yet docker pull dellemc/csi-unity:v2.1.0. hence closing this bug.

this is not relevant to the BUG, do not close it, i just mentioned that i'm going to try v2.1.0 as well, if it's not released yet, then im gonna stick with v2.0.0 and the BUG is still there.

please refer to the ERROR mentioned. Error: template: csi-unity/templates/node.yaml:142:85: executing "csi-unity/templates/node.yaml" at <.Values.images.driver>:nil pointer evaluation interface{}.driver

@guy7711 - Do ensure that you are pointed to the right code in github(pull from v2.0.0 tag instead of main branch) git clone -b v2.0.0 https://github.com/dell/csi-unity.git Refer this section https://dell.github.io/csm-docs/docs/csidriver/installation/helm/unity/#install-csi-driver

[prablr79]

@guy7711 sorry , we will help you on this bug, please share your observation

[shanmydell]

@guy7711 : Yes this is a latest issue, This issue has been already reported https://github.com/dell/csm/issues/99 and fixed as part of https://github.com/dell/csi-unity/pull/32, Please pull the latest code from main and let us know if you are still facing the issue.

[prablr79]

@guy7711 i guess this due to change in version required in https://github.com/dell/csi-unity/blob/main/helm/csi-unity/driver-image.yaml, please change image as v2.0.0 then you should be able install the driver.

[guy7711]

i will try again as suggested above and update soon, thanks for the answers

[guy7711]

Hi, The issue was not resolved, i ran git clone -b v2.0.0 https://github.com/dell/csi-unity.git and cleared the files, editted all values.yaml files, including the drivers files and added the repository URL path.

still, same issue

[guy7711]

i found the problem, there is an issue with the helm chart. when i edit the node-template.yaml file, adding the images url manually, it doesnt complain and move forward with the same error for the next image - same error different line (195:91)

apparently there is a problem with the helm chart file links

[shanmydell]

@guy7711 : Have you tried git clone https://github.com/dell/csi-unity.git the latest branch from main. Could you please try and update on the same.

[guy7711]

Fixed the issue by doing the following:

Copied all images: pointers from the relevant k8s-1.20-values.yaml and added the image from driver-image.yaml as well to: values.yaml.

helm install worked.
