Configuration example

<Repo>.contentservice.azureblobstorev2.invalidcharacters= 
<Repo>.contentservice.azureblobstorev2.region = azure
<Repo>.contentservice.azureblobstorev2.minparallelsize = 4194304
<Repo>.contentservice.azureblobstorev2.maxconcurrency = 2
<Repo>.contentservice.azureblobstorev2.blocksize = 4194304
<Repo>.contentservice.azureblobstorev2.singleuploadsize = 4194304

...

To use this feature, it is necessary to create a container with the "version-level immutability" option. See: https://learn.microsoft.com/en-us/azure/storage/blobs/immutable-policy-configure-version-scope?tabs=azure-portal

tia Content Server will manage the retention periods do not set default retention times on Azure.

This can be enabled in the Azure StorageAccount in a manually creation process of a container or via a corresponding configuration in tia Core, which is described below.

If the container creation is to be done by tia core, the following parameters must be added to the repository.cfg.

Configuration example immutability policies

<Repo>.contentservice.azureblobstorev2.allowcreatecontainer=false
<Repo>.contentservice.azureblobstorev2.enableversioning=true
<Repo>.contentservice.azureblobstorev2.management.tenantId=
<Repo>.contentservice.azureblobstorev2.management.clientSecret=
<Repo>.contentservice.azureblobstorev2.management.clientId=
<Repo>.contentservice.azureblobstorev2.management.subcriptionId=
<Repo>.contentservice.azureblobstorev2.management.resourceGroupName=
<Repo>.contentservice.azureblobstorev2.management.accountName=

Anchor
Naming Naming

Container naming convention:

...

• Container names must begin or end with a letter or number and may contain only letters, numbers, and hyphens (-).

• Each hyphen (-) must be immediately preceded and followed by a letter or number; in addition, multiple hyphens may not directly follow each other.

• The container name must contain lowercase letters only.

• Container names must be between 3 and 63 characters long.

0er Container (Feature for Migration) (not supported by azureblobstorev2)

As of tia tia® Core version 2.0.5, it is possible to configure a container for storing "expired" documents.

...

<Repo>.contentservice.azureblobstore.container=test1                    # Container for metadata and retention information
<Repo>.contentservice.azureblobstore.container.retention.0=test-0       # Container for expired documents 

Managed Identity

Managed Identity bewares you of copying and configuring security relevant parameters. It only works if blob store and tia core is hosted in Azure. (Same is valid for SQL db)

Azure knows 2 kinds of managed identity. Tia core can use both. Here shown is only server managed identity. On tia core configuration this distinction has no influence.

Managed Identity (Storage Account)

The blob store needs to have the role “Storage Blob Data Contributor”. There you add the app id of tia core. Then you can configure for blob store the storageendpoint instead of connectionstring.

Here the way to allow tia core to use managed identity.
