--- layout: default navsection: installguide title: Configure Azure Blob storage ... As an alternative to local and network-attached POSIX filesystems, Keepstore can store data in an Azure Storage container. h2. Create a container Normally, all keepstore services are configured to share a single Azure Storage container. Using the Azure web portal or command line tool, create or choose a storage account with a suitable redundancy profile and availability region. Use the storage account keys to create a new container.
~$ azure config mode arm
~$ azure login
~$ azure group create exampleGroupName eastus
~$ azure storage account create --type LRS --location eastus --resource-group exampleGroupName exampleStorageAccountName
~$ azure storage account keys list --resource-group exampleGroupName exampleStorageAccountName

h2. Configure keepstore Copy the primary storage account key to a file where it will be accessible to keepstore at startup time.
~$ sudo sh -c 'cat >/etc/sv/keepstore/exampleStorageAccountName.key <<EOF'
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz==
EOF
~$ sudo chmod 0400 /etc/sv/keepstore/exampleStorageAccountName.key
In your keepstore startup script, instead of specifying a local storage using @-volume /path@ or discovering mount points automatically, use @-azure-*@ arguments to specify the storage container:
#!/bin/sh

exec 2>&1
exec keepstore \
 -azure-storage-account-key-file /etc/sv/keepstore/exampleStorageAccountName.key \
 -azure-storage-account-name exampleStorageAccountName \
 -azure-storage-container-volume exampleContainerName
Start (or restart) keepstore, and check its log file to confirm it is using the new configuration.
