For each entry in the data set, the foreach command will execute all subsequent commands until a foreach.end has been found.

By default the current iteration item can be accessed using ${vars.loop.item}.

For example:

vars:
  people: ["Sam", "Sarah", "Carol"]

pipeline:

  - foreach:
      in: ${vars.people}

  - log:
      message: "Hello ${vars.loop.item}"

  - foreach.end

You can also define a loop item name using the as parameter. In this case for reach iteration, the item is placed in the vars scope under the name specified by the as parameter:

vars:
  people: ["Sam", "Sarah", "Carol"]

pipeline:

  - foreach:
      in: ${vars.people}
      as: person

  - log:
      message: "Hello ${vars.person}"

  - foreach.end
