Pact CLI

This tool provides an amalgamated CLI of all the Pact CLI tools available in the Pact Ruby implementation (publish and verify pacts, and interact with the Pact Broker). While it is functionally the same as the pact-ruby-standalone it is packaged as a Docker container and a single top level entrypoint (pact).

Platforms

Single platform images

By default, vanilla tags, are built only for amd64

--platform=linux/amd64

docker run --rm -it pactfoundation/pact-cli:latest /bin/sh -c 'uname -sm'

Multi-manifest image

Multi-platform images are available, by appending -multi to any release tag

--platform=linux/amd64
--platform=linux/arm

--platform=linux/arm64

docker run --rm it pactfoundation/pact-cli:latest-multi /bin/sh -c 'uname -sm'

Usage

You can run the following examples against a public test Pact Broker with the following credentials:

export PACT_BROKER_BASE_URL="https://test.pactflow.io"
export PACT_BROKER_USERNAME="dXfltyFMgNOFZAxr8io9wJ37iUpY42M"
export PACT_BROKER_PASSWORD="O5AIZWxelWbLvqMd8PkAVycBJh2Psyg1"

The $(date +%s) in the examples is just to generate a pseudo random GIT_COMMIT.

If you are using a Pact Broker with bearer token authentication (eg. PactFlow), then set PACT_BROKER_TOKEN instead of the username and password.

Docker gotchas

If you are publishing pacts, don't forget to mount your pacts into the docker container using the -v flag, documented in the example below.
If you are connecting to a Pact Broker that you are running on localhost, you will need to add --network="host" to the docker command so that it resolves localhost to your machine, rather than to the container itself.

Publish pacts

You can clone [email protected]:pact-foundation/pact-ruby-cli.git (https://github.com/pact-foundation/pact-ruby-cli) and run the following from the root directory.

docker run --rm \
 -w ${PWD} \
 -v ${PWD}:${PWD} \
 -e PACT_BROKER_BASE_URL \
 -e PACT_BROKER_USERNAME \
 -e PACT_BROKER_PASSWORD \
  pactfoundation/pact-cli:latest \
  publish \
  ${PWD}/example/pacts \
  --consumer-app-version fake-git-sha-for-demo-$(date +%s) \
  --tag-with-git-branch

See https://github.com/pact-foundation/pact_broker-client#publish for all publish options.

Demo only - publish an example pact from data baked into the docker image

docker run --rm  \
  -e PACT_BROKER_BASE_URL  \
  -e PACT_BROKER_USERNAME  \
  -e PACT_BROKER_PASSWORD  \
  pactfoundation/pact-cli:latest \
  publish \
  /pact/example/pacts \
  --consumer-app-version fake-git-sha-for-demo-$(date +%s)

Verify pacts

See the example docker-compose-verify.yml

PACT_BROKER_PUBLISH_VERIFICATION_RESULTS=true GIT_COMMIT=fake-git-sha-for-demo$(date +%s) GIT_BRANCH=master \
  docker-compose -f docker-compose-verify.yml \
  up --build --abort-on-container-exit --exit-code-from pact_verifier

See https://github.com/pact-foundation/pact-provider-verifier/#usage for all verification options.

Can I deploy?

docker run --rm \
 -e PACT_BROKER_BASE_URL \
 -e PACT_BROKER_USERNAME \
 -e PACT_BROKER_PASSWORD \
  pactfoundation/pact-cli:latest \
  pact-broker can-i-deploy \
  --pacticipant docker-example-consumer \
  --latest

See https://github.com/pact-foundation/pact_broker-client#can-i-deploy for all options.

Tag a pacticipant version

docker run --rm \
 -e PACT_BROKER_BASE_URL \
 -e PACT_BROKER_USERNAME \
 -e PACT_BROKER_PASSWORD \
  pactfoundation/pact-cli:latest \
  pact-broker create-version-tag \
  --pacticipant docker-example-consumer \
  --version fake-git-sha-for-demo-$(date +%s) \
  --tag prod

See https://github.com/pact-foundation/pact_broker-client#create-version-tag for all options.

Mock service

docker run -dit \
  --rm \
  --name pact-mock-service \
  -p 1234:1234 \
  -v ${HOST_PACT_DIRECTORY}:/tmp/pacts \
  pactfoundation/pact-cli:latest \
  mock-service \
  -p 1234 \
  --host 0.0.0.0 \
  --pact-dir /tmp/pacts

The -it is required if you want the container to respond to a ctl+c. The container takes an unexpectedly long time to shut down when using docker stop. This is an open issue.

See https://github.com/pact-foundation/pact-mock_service#mock-service-usage for all options.

Using a custom certificate

docker run --rm \
 -v <PATH_TO_CERT_FILE_ON_HOST>:/tmp/cacert.pem \
 -e SSL_CERT_FILE=/tmp/cacert.pem \
 pactfoundation/pact-cli:latest ...

You can also set SSL_CERT_DIR and mount the directory instead of the file.

Shell access inside Docker container

To meet with Docker consistency rules sh access is provided, NOTE: bash is not installed in the container

$ docker run --rm pactfoundation/pact-cli sh -c 'ls'
Gemfile
Gemfile.lock
bin
entrypoint.sh
example
lib
pact-cli.gemspec

$ docker run --rm pactfoundation/pact-cli ls
Gemfile
Gemfile.lock
bin
entrypoint.sh
example
lib
pact-cli.gemspec
