Unable to authenticate to OpenStack

[Michael Kelly]

Hi,

I am trying to install Velero 1.11.0 into a K3S cluster using OpenStack as the storage provider.

I have exported all the environment variables needed for Keystone v2.0.

The install command is

velero install  --provider "community.openstack.org/openstack" --plugins lirt/velero-plugin-for-openstack:v0.5.1 --bucket Velero-Backups --no-secret

The install completes  and the pod is created but when I look at the logs, I can see that there was an error when trying to authenticate to OpenStack.

The error message is

failed to authenticate against OpenStack: Missing input for argument [auth_url]"

The help for the install command makes no reference to auth_url.

What am I missing or doing wrong?

See how to set credentials config for the plugin Lirt/velero-plugin-for-openstack: Openstack Cinder and Swift plugin for Velero backups. (github.com)

This plugin is not maintained by the velero maintainers (it's in Lirt org). Config for specific provider plugins are in their designated plugin repositories and is not part of the `velero install` documentation.

Please review the documentation and file issues if you think sections could be improved. If you already know what needs to be changed, make a pull request!

The aim should be that someone only has to ask once, and it can be easily looked up. You can find discussions of other velero users at

I understand that the Velero maintainers are not responsible for the OpenStack plugin.

I'm hoping that somebody who knows more about the plugin than I do can help me out here.

If you're using file or application credentials to authenticate

https://github.com/Lirt/velero-plugin-for-openstack#authentication-using-file

clouds:
  <CLOUD_NAME_1>:
    region_name: <REGION_NAME>
    auth:
      auth_url: "<AUTH_URL /v3>" <-- this is the missing input.

If you are using env var to auth https://github.com/Lirt/velero-plugin-for-openstack#authentication-using-environment-variables

You are missing

export OS_AUTH_URL=<AUTH_URL /v2.0> <-- this is the missing input.

All this came from the README I linked previously and linked again above.

Yes I did.

I followed the instructions in the README.

I'm hoping that someone can explain what Missing input for argument [auth_url] means.

I exported all the env vars for v2.0, that's what's puzzling me.

[Tiger Kaovilai]

It said "Configure velero container with your OpenStack authentication environment variables:"

So my assumption is they want you to edit velero deployment pod template spec's environment variables to contain those values.

You can do it directly in env, or you could create a secret then use them as envvar

[Tiger Kaovilai]

1. Authentication using environment variables takes precedence (including Application Credentials).You must not set env. variable OS_CLOUD when you want to authenticate using env.variables because authenticator will try to look for clouds.y(a)ml file and use it.

If it's still not working.. I would defer you to file issues with them.

HI Team,

Did you have a solution for this error. I too get same error configuring openstack velero.

I gave all below ENV variable as per the doc but same error i get.

export OS_AUTH_URL=

export OS_USERNAME=

export OS_PASSWORD=

export OS_PROJECT_ID

export OS_PROJECT_NAME=

export OS_REGION_NAME=

ERROR:
