Work with BLOB storage containers

12 min

Storage accounts are provisioned as part of a DXP project and are used for various purposes (for example, access logs or to download site contents). The storage container API allows access to the BLOB storage containers and contents. The API has the following operations.

List – Lists the available BLOB storage containers.

Generate SAS link – Generates a read-only SAS link for a blob container with a dynamic link expiration time

The storage containers API uses an authentication mechanism similar to other deployment APIs. See Deployment API authenticationDeployment API authentication.

Epicloud Module

The

EpiCloud PowerShell module adds the Get-EpiStorageContainer and Get-EpiStorageContainerSasLink cmdlets to perform the storage containers API operations using PowerShell. To install the module and connect with the authentication mechanism, see Deploy using PowerShellDeploy using PowerShell for information about how to install the EpiCloud module.

Get-EpiStorageContainer

Fetches the list of BLOB storage containers for an environment in the project.

Get-EpiStorageContainer -ProjectId "76443fa4-ad6a-4517-a382-ac5900a18fa4" -Environment "Integration"

projectId                            environment storageContainers
---------                            ----------- -----------------
76443fa4-ad6a-4517-a382-ac5900a18fa4 Integration {azure-application-logs, azure-web-logs}

Get-EpiStorageContainerSasLink

Generates a new read-only SAS link for a specific BLOB storage container. The -RetentionHours parameter takes a dynamic value for the SAS link expiry; if it is not provided, a default 24 hours is used to generate the link.

Get-EpiStorageContainerSasLink -ProjectId "2372b396-6fd2-40ca-a955-57871fc497c9" `
  -Environment "Preproduction" `
  -StorageContainer "azure-web-logs" `
