Trigger

type: "io.kestra.plugin.azure.storage.blob.Trigger"

Wait for files on the Azure Blob Storage.

This trigger will poll every interval on the Azure Blob Storage. You can search for all files in a container or directory in from or you can filter the files with a regExp.The detection is atomic, internally we do a list and interact only with files listed. Once a file is detected, we download the file on internal storage and processed with declared action in order to move or delete the files from the container (to avoid double detection on new poll)

Examples

Wait for a list of files on Azure Blob Storage bucket, and then iterate through the files.

id: storage_listen
namespace: company.team

tasks:
  - id: each
    type: io.kestra.plugin.core.flow.EachSequential
    tasks:
      - id: return
        type: io.kestra.plugin.core.debug.Return
        format: "{{ taskrun.value }}"
    value: "{{ trigger.blobs | jq('.[].uri') }}"

triggers:
  - id: watch
    type: io.kestra.plugin.azure.storage.blob.Trigger
    interval: PT5M
    endpoint: "https://yourblob.blob.core.windows.net"
    connectionString: "DefaultEndpointsProtocol=...=="
    container: "mydata"
    prefix: "trigger/storage-listen"
    action: MOVE
    moveTo:
      container: mydata
      name: archive

Wait for a list of file on a Azure Blob Storage bucket and iterate through the files. Delete files manually after processing to prevent infinite triggering.
