Trigger

yaml

type: "io.kestra.plugin.minio.Trigger"

Wait for files on a bucket.

This trigger will list every interval a bucket. You can search for all files in a bucket 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 bucket (to avoid double detection on new poll).

Examples

Wait for a list of files on a bucket and iterate through the files.

yaml

id: minio_listen
namespace: company.team

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

triggers:
  - id: watch
    type: io.kestra.plugin.minio.Trigger
    interval: "PT5M"
    accessKeyId: "<access-key>"
    secretKeyId: "<secret-key>"
    region: "eu-central-1"
    bucket: "my-bucket"
    prefix: "sub-dir"
    action: MOVE
    moveTo:
      key: archive"

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

yaml

id: minio_listen
namespace: company.team

tasks:
  - id: each
    type: io.kestra.plugin.core.flow.ForEach
    values: "{{ trigger.objects | jq('.[].key') }}"
    tasks:
      - id: return
        type: io.kestra.plugin.core.debug.Return
        format: "{{ taskrun.value }}"
      - id: delete
        type: io.kestra.plugin.minio.Delete
        accessKeyId: "<access-key>"
        secretKeyId: "<secret-key>"
        region: "eu-central-1"
        bucket: "my-bucket"
        key: "{{ taskrun.value }}"

triggers:
  - id: watch
    type: io.kestra.plugin.minio.Trigger
    interval: "PT5M"
    accessKeyId: "<access-key>"
    secretKeyId: "<secret-key>"
    region: "eu-central-1"
    bucket: "my-bucket"
    prefix: "sub-dir"
    action: NONE

Wait for a list of files on a bucket on an S3-compatible storage — here, Spaces Object Storage from Digital Ocean. Iterate through those files, and move it to another folder.

yaml

id: trigger_on_s3_compatible_storage
namespace: company.team
tasks:
  - id: each
    type: io.kestra.plugin.core.flow.ForEach
    values: "{{ trigger.objects | jq('.[].uri') }}"
    tasks:
      - id: return
        type: io.kestra.plugin.core.debug.Return
        format: "{{ taskrun.value }}"

triggers:
  - id: watch
    type: io.kestra.plugin.minio.Trigger
    interval: "PT5M"
    accessKeyId: "<access-key>"
    secretKeyId: "<secret-key>"
    endpoint: https://<region>>.digitaloceanspaces.com
    bucket: "kestra-test-bucket"
    prefix: "sub-dir"
    action: MOVE
    moveTo:
      key: archive

`interval`

Type: string
Dynamic: ❌

Format: duration

Interval between polling.

The interval between 2 different polls of schedule, this can avoid to overload the remote system with too many calls. For most of the triggers that depend on external systems, a minimal interval must be at least PT30S. See ISO_8601 Durations for more information of available interval values.
