I can’t seem to make CI pipeline work when provider is deployed first. Getting

Computer says no

on

can-i-deploy

. Steps taken on thread.

you haven’t shown any steps, where you’ve actually verified the consumer pact against the provider, so the output looks correct to me

Which steps am I missing? Or could clarify? FYI: they are both golang services using pact-go

It looks like you are missing the key part, which is verifying the consumer contract is aligned with your provider. There are two ways to verify pacts https://docs.pact.io/pact_nirvana/step_4#verifying-pacts It looks like you’ve just set up 1 and haven’t setup anything to verify the changed pact. https://docs.pact.io/pact_nirvana/step_6#add-a-new-provider-verification-job

The

make test

on the provider would run this go test, wouldn’t this handle that verification:

err := verifier.VerifyProvider(t, provider.VerifyRequest{
		BrokerURL:                  os.Getenv("PACT_BROKER_BASE_URL"),
		ProviderBaseURL:            "http://" + serverAddress,
		PublishVerificationResults: os.Getenv("CI") == "true",
		ProviderVersion:            os.Getenv("VERSION"),
		ProviderBranch:             "master",
		Provider:                   "provider-service",
		ConsumerVersionSelectors: []provider.Selector{
			&provider.ConsumerVersionSelector{
				MainBranch: true,
			},
			&provider.ConsumerVersionSelector{
				DeployedOrReleased: true,
			},
			&provider.ConsumerVersionSelector{
				MatchingBranch: true,
			},
		},
	})

it should grab it under

MainBranch

consumer version selector, but that would rely on you running that provider verification job again (either manually) or on the next provider change, in order for it to verify it and publish results. that time gap for feedback is usually too long, which is why you have a task utilising webhooks, your verification task should accept a pactUrl and if one exists not pass any consumer version selectors to the broker. This is a verification triggered by a pact change.

Thanks @Yousaf Nabi (pactflow.io). I’m trying to run manually before working on the webhook. It’s not working, what am I missing? Consumer:

❯ pact-broker publish  "./backend/pacts/" --consumer-app-version 1.0.0 --branch "master" --broker-base-url "<http://127.0.0.1:9292>"
Updated consumer-service version 1.0.0 with branch master
Pact successfully republished for consumer-service version 1.0.0 and provider provider-service with no content changes.
  View the published pact at <http://127.0.0.1:9292/pacts/provider/provider-service/consumer/consumer-service/version/1.0.0>
  Events detected: contract_published, contract_requiring_verification_published
  Next steps:
    * Add Pact verification tests to the provider-service build. See <https://docs.pact.io/go/provider_verification>
    * Configure separate provider-service pact verification build and webhook to trigger it when the pact content changes. See <https://docs.pact.io/go/webhooks>

Consumer match version is a few message above.

can you try with just the MainBranch selector, or provide a PactUrl which would be the published contract

wow, you are right
