Environment

VMware Tanzu Mission Control

Cause

This issue occurs when the credentials-velero file is not correctly formatted. The correct format should be:

cat << EOF > ./credentials-velero
AZURE_SUBSCRIPTION_ID=${AZURE_SUBSCRIPTION_ID}
AZURE_TENANT_ID=${AZURE_TENANT_ID}
AZURE_CLIENT_ID=${AZURE_CLIENT_ID}
....

....
EOF

Common mistakes include:

• Formatting the file in JSON instead of plain text.
• Adding unnecessary characters such as {} or extra spaces.

Resolution

Ensure that the credentials-velero file is created exactly as described in the documentation. Avoid unnecessary formatting changes or additional characters that could cause the deployment to fail.
