Why aren't my 2.0 tests using parallel containers?


#1

We made a change on 15 June 2017. If you’re building on 2.0 you now need to set the parallelism key with the number of parallel containers you want to use. See: https://circleci.com/docs/2.0/configuration-reference/#jobs

e.g:

jobs:
  build:
    docker:
      - buildpack-deps:trusty
    environment:
      - FOO: "bar"
    parallelism: 3
    working_directory: ~/my-app
    branches:
      only:
        - master
        - /rc-.*/
    steps:
      - run: make test
      - run: make

Note: the UI ‘Adjust parallelism’ settings page no longer has any effect on 2.0 jobs. You must set it explicitly in .circleci/config.yml.


Parallelism setting does not seem to work?
