Using matrix jobs
On This Page
Matrix jobs provide a way to run a job multiple times with arguments. Arguments are supplied using parameters. There are many uses for this feature, including testing on multiple operating systems and against different language/library versions.
Use matrix jobs to run multiple OS tests
In the following example the
test job is run across a Linux Docker container, Linux VM, and macOS environments, using two different versions of Node.js. On each run of the
test job different parameters are passed to set both the OS and the Node.js version:
version: 2.1 orbs: node: email@example.com executors: docker: # Docker using the Base Convenience Image docker: - image: cimg/base:stable auth: username: mydockerhub-user password: $DOCKERHUB_PASSWORD # context / project UI env-var reference linux: # a Linux VM running Ubuntu 20.04 machine: image: ubuntu-2004:202107-02 macos: # macos executor running Xcode macos: xcode: 12.5.1 jobs: test: parameters: os: type: executor node-version: type: string executor: << parameters.os >> steps: - checkout - node/install: node-version: << parameters.node-version >> install-yarn: true workflows: all-tests: jobs: - test: matrix: parameters: os: [docker, linux, macos] node-version: ["14.17.6", "16.9.0"]
List jobs that will run
The expanded version of this matrix runs the following list of jobs under the
- test-14.17.6-docker - test-16.9.0-docker - test-14.17.6-linux - test-16.9.0-linux - test-14.17.6-macos - test-16.9.0-macos
