Trigger

yaml

type: "io.kestra.plugin.fs.sftp.Trigger"

Trigger a flow as soon as new files are detected in a given SFTP server's directory.

Examples

Wait for one or more files in a given SFTP server's directory and process each of these files sequentially.

yaml

id: sftp_trigger_flow
namespace: company.team

tasks:
  - id: for_each_file
    type: io.kestra.plugin.core.flow.EachSequential
    value: "{{ trigger.files }}"
    tasks:
      - id: return
        type: io.kestra.plugin.core.debug.Return
        format: "{{ taskrun.value | jq('.path') }}"

triggers:
  - id: watch
    type: io.kestra.plugin.fs.sftp.Trigger
    host: localhost
    port: 6622
    username: foo
    password: bar
    from: "/in/"
    interval: PT10S
    action: MOVE
    moveDirectory: "/archive/"

Wait for one or more files in a given SFTP server's directory and process each of these files sequentially. Delete files manually after processing to prevent infinite triggering.

yaml

id: sftp_trigger_flow
namespace: company.team

tasks:
  - id: for_each_file
    type: io.kestra.plugin.core.flow.EachSequential
    value: "{{ trigger.files | jq('.path') }}"
    tasks:
      - id: return
        type: io.kestra.plugin.core.debug.Return
        format: "{{ taskrun.value }}"
      - id: delete
        type: io.kestra.plugin.fs.sftp.Delete
        host: localhost
        port: 6622
        username: foo
        password: bar
        uri: "/in/{{ taskrun.value }}"

triggers:
  - id: watch
    type: io.kestra.plugin.fs.sftp.Trigger
    host: localhost
    port: 6622
    username: foo
    password: bar
    from: "/in/"
    interval: PT10S
    action: NONE

Wait for one or more files in a given SFTP server's directory and process each of these files sequentially. In this example, we restrict the trigger to only wait for CSV files in the mydir directory.

yaml

id: ftp_wait_for_csv_in_mydir
namespace: company.team

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

triggers:
  - id: watch
    type: io.kestra.plugin.fs.sftp.Trigger
    host: localhost
    port: "6622"
    username: foo
    password: bar
    from: "mydir/"
    regExp: ".*.csv"
    action: MOVE
    moveDirectory: "archive/"
    interval: PTS
