Contoh kode

YAML

- assignStep:  # these variables can be read by any branch
    assign:
      - input: ["apples", "oranges"]
      - my_result: {}
- parallelStep:
    parallel:
      shared: [my_result]  # my_result is now writable by any branch
      branches:
        - getStock:
            steps:
              - callGetStock:
                  call: http.get
                  args:
                    url: ${"http://mystore.com/getStock/" + input[0]}
                  result: local_result  # local_result is local to this branch scope
              - assignResult1:
                  assign:
                    - my_result["getStock"]: ${local_result.body.some.entry}  # ok, my_result has shared scope and is writable
                    - temp: 1  # ok, variable is local to branch scope
                    - temp2: "foo"  # ok, variable is local to branch scope
                  # - input: 5  # deployment error, defined in the parent scope but not marked "shared"
        - orderStock:
            steps:
              - callOrderStock:
                  call: http.get
                  args:
                    url: ${"http://mystore.com/orderStock/" + input[1]}
                  result: local_result  # local_result is local to this branch
              - assignResult2:
                  assign:
                    - my_result["orderStock"]: ${local_result.body.some.entry}  # ok, my_result has shared scope and is writable
                    - temp: 2  # ok, variable is local to branch scope
                  # - temp: ${temp2}  # deployment error, temp2 is not defined in this branch
