--set-file credentials.secretContents.cloud=<FULL PATH TO FILE> \
--set configuration.backupStorageLocation.name=azure \
--set configuration.backupStorageLocation.bucket=<BUCKET NAME> \
--set configuration.volumeSnapshotLocation.name=<PROVIDER NAME> \
--set configuration.volumeSnapshotLocation.config.region=<REGION> \
--set image.repository=velero/velero \
--set image.tag=v1.2.0 \
--set image.pullPolicy=IfNotPresent \
--set initContainers[0].name=velero-plugin-for-microsoft-azure:v1.0.0 \

stable/velero
I have configured the below environment variables in credential-velero file and path has been provided in above command.
credentials-velero file -
AZURE_SUBSCRIPTION_ID=${AZURE_SUBSCRIPTION_ID}
AZURE_TENANT_ID=${AZURE_TENANT_ID}
AZURE_CLIENT_ID=${AZURE_CLIENT_ID}
AZURE_CLIENT_SECRET=${AZURE_CLIENT_SECRET}
AZURE_RESOURCE_GROUP=${AZURE_RESOURCE_GROUP}
AZURE_CLOUD_NAME=AzurePublicCloud
I am getting below error -
an error occurred: some backup storage locations are invalid: error getting backup store for location "default": rpc error: code = Unknown desc = unable to get all required environment variables: the following keys do not have values: AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET, AZURE_SUBSCRIPTION_ID
Could you please help with resolution of above error?

Answer 1

Your velero credential files should contain values for those, not placeholders.
cat << EOF > ./credentials-velero
AZURE_SUBSCRIPTION_ID=${AZURE_SUBSCRIPTION_ID}
AZURE_TENANT_ID=${AZURE_TENANT_ID}
AZURE_CLIENT_ID=${AZURE_CLIENT_ID}
AZURE_CLIENT_SECRET=${AZURE_CLIENT_SECRET}
AZURE_RESOURCE_GROUP=${AZURE_RESOURCE_GROUP}
AZURE_CLOUD_NAME=AzurePublicCloud
EOF

Answer 2

use this way
AZURE_SUBSCRIPTION_ID=XXXX-XXXXX-XXXXXXX-XXXXXXX
AZURE_TENANT_ID=XXXX-XXXXX-XXXXXXX-XXXXXXX
AZURE_CLIENT_ID=XXXX-XXXXX-XXXXXXX-XXXXXXX
AZURE_CLIENT_SECRET=XXXXXXXXXXXXXXXXXX
AZURE_RESOURCE_GROUP=MC_RESOURCE_GROUP_NAME_OF_AKS # this should be the MC resource group
AZURE_CLOUD_NAME=AzurePublicCloud
Also try using the master image
--set initContainers[0].image=velero/velero-plugin-for-microsoft-azure:master
Use this format
helm install velero vmware-tanzu/velero --namespace velero \
--set-file credentials.secretContents.cloud=./credentials-velero \
--set configuration.provider=azure \
--set configuration.backupStorageLocation.name=azure \
--set configuration.backupStorageLocation.bucket='velero' \
--set configuration.backupStorageLocation.config.resourceGroup=RESOURCE_GROUP_OF_STORAGEACCOUNT \
--set configuration.backupStorageLocation.config.storageAccount=STORAGE_ACCOUNT_NAME \
--set snapshotsEnabled=true \
--set deployRestic=true \
--set image.repository=velero/velero \
--set image.pullPolicy=Always \
--set initContainers[0].name=velero-plugin-for-microsoft-azure \
--set initContainers[0].image=velero/velero-plugin-for-microsoft-azure:master \
--set initContainers[0].volumeMounts[0].mountPath=/target \
--set initContainers[0].volumeMounts[0].name=plugins
