Arbitrary Workflows with Dependencies between Nodes¶
Scrutinizer allows you to create arbitrary workflows. In the typical case, you can use that to run deployment at the very end after all your tests have passed and no failure conditions were met during the analysis.
You can also use dependencies between nodes to run some heavy compilation on a single node, cache the result and then run tests on the compiled artifacts on various following nodes in parallel.
Each node can declare requirements which all have to be satisfied before the node can be started:
build: nodes: some-node: requires: - node: other-node # all commands in the node have to be successful - branch: master # only runs when the branch is "master" - is_pull_request: true # only runs on pull-requests - is_pull_request: false # only runs on non-pull-requests (pushes/tags/manual) - analysis # no failure conditions must be met in the analysis
Splitting Compilation and Testing¶
In the example below, we will run compilation with a high number of CPUs and the following tests runs split across multiple nodes in parallel with less resources each. When all tests pass, the code is deployed:
build: nodes: compile: resources: cpus: 8 commands: - checkout-code ~/code - (cd ~/code && ./compile) - store-in-cache execution compile-result ~/code tests-1: requires: - node: compile commands: - restore-from-cache execution compile-result - ./code/tests-1 tests-2: requires: - node: compile commands: - restore-from-cache execution compile-result - ./code/tests-2 deploy: requires: - node: /tests-\d+/ - branch: master commands: - restore-from-cache execution compile-result - ./code/deploy
