-d, [--pact-dir=PACT_DIR] # Directory to which the pacts will be written
-m, [--pact-file-write-mode=PACT_FILE_WRITE_MODE] # `overwrite` or `merge`. Use `merge` when running multiple mock service instances in parallel for the same consumer/provider pair. Ensure the pact file is deleted before running tests when using this option so that interactions deleted from the code are not maintained in the file.
# Default: overwrite
-i, [--pact-specification-version=PACT_SPECIFICATION_VERSION] # The pact specification version to use when writing the pact. Note that only versions 1 and 2 are currently supported.
# Default: 2
-l, [--log=LOG] # File to which to log output
[--log-level=LOG_LEVEL] # Log level. Options are DEBUG INFO WARN ERROR
# Default: DEBUG
-o, [--cors=CORS] # Support browser security in tests by responding to OPTIONS requests and adding CORS headers to mocked responses
[--ssl], [--no-ssl], [--skip-ssl] # Use a self-signed SSL cert to run the service over HTTPS
# Default: false
[--sslcert=SSLCERT] # Specify the path to the SSL cert to use when running the service over HTTPS
[--sslkey=SSLKEY] # Specify the path to the SSL key to use when running the service over HTTPS
Start a mock service. If the consumer, provider and pact-dir options are provided, the pact will be written automatically on shutdown (INT).
pact-stub-service
Usage:
pact-stub-service PACT_URI ...
Options:
-p, [--port=PORT] # Port on which to run the service
-h, [--host=HOST] # Host on which to bind the service
# Default: localhost
-l, [--log=LOG] # File to which to log output
-n, [--broker-username=BROKER_USERNAME] # Pact Broker basic auth username
-p, [--broker-password=BROKER_PASSWORD] # Pact Broker basic auth password
-k, [--broker-token=BROKER_TOKEN] # Pact Broker bearer token (can also be set using the PACT_BROKER_TOKEN environment variable)

[--sslcert=SSLCERT] # Specify the path to the SSL cert to use when running the service over HTTPS
[--sslkey=SSLKEY] # Specify the path to the SSL key to use when running the service over HTTPS
Description:
Start a stub service with the given pact file(s) or directories. Pact URIs
may be local file or directory paths, or HTTP. Include any basic auth details
in the URL using the format https://USERNAME:PASSWORD@URI. Where multiple
matching interactions are found, the interactions will be sorted by response
status, and the first one will be returned. This may lead to some
non-deterministic behaviour. If you are having problems with this, please
raise it on the pact-dev google group, and we can discuss some potential
enhancements. Note that only versions 1 and 2 of the pact specification are
currently fully supported. Pacts using the v3 format may be used, however,
any matching features added in v3 will currently be ignored.

can-i-deploy
Usage:
pact-broker can-i-deploy -a, --pacticipant=PACTICIPANT -b, --broker-base-url=BROKER_BASE_URL
Options:
-a, --pacticipant=PACTICIPANT # The pacticipant name. Use once for each pacticipant being checked.
-e, [--version=VERSION] # The pacticipant version. Must be entered after the --pacticipant that it relates to.
[--ignore=PACTICIPANT] # The pacticipant name to ignore. Use once for each pacticipant being ignored. A specific version can be ignored by also specifying a --version after the pacticipant name option. The environment variable PACT_BROKER_CAN_I_DEPLOY_IGNORE may also be used to specify a pacticipant name to ignore, with commas to separate multiple pacticipant names if necessary.
-l, [--latest=[TAG]] # Use the latest pacticipant version. Optionally specify a TAG to use the latest version with the specified tag.
[--branch=BRANCH] # The branch of the version for which you want to check the verification results.
[--main-branch], [--no-main-branch], [--skip-main-branch] # Use the latest version of the configured main branch of the pacticipant as the version for which you want to check the verification results
# Default: false
[--to-environment=ENVIRONMENT] # The environment into which the pacticipant(s) are to be deployed
[--to=TAG] # The tag that represents the branch or environment of the integrated applications for which you want to check the verification result status.
-o, [--output=OUTPUT] # json or table
# Default: table
[--retry-while-unknown=TIMES] # The number of times to retry while there is an unknown verification result (ie. the provider verification is likely still running)
# Default: 0
[--retry-interval=SECONDS] # The time between retries in seconds. Use in conjuction with --retry-while-unknown
# Default: 10
[--dry-run], [--no-dry-run], [--skip-dry-run] # When dry-run is enabled, always exit process with a success code. Can also be enabled by setting the environment variable PACT_BROKER_CAN_I_DEPLOY_DRY_RUN=true. This mode is useful when setting up your CI/CD pipeline for the first time, or in a 'break glass' situation where you need to knowingly deploy what Pact considers a breaking change. For the second scenario, it is recommended to use the environment variable and just set it for the build required to deploy that particular version, so you don't accidentally leave the dry run mode enabled.
# Default: false
-b, --broker-base-url=BROKER_BASE_URL # The base URL of the Pact Broker
-u, [--broker-username=BROKER_USERNAME] # Pact Broker basic auth username
-p, [--broker-password=BROKER_PASSWORD] # Pact Broker basic auth password
-k, [--broker-token=BROKER_TOKEN] # Pact Broker bearer token
-v, [--verbose], [--no-verbose], [--skip-verbose] # Verbose output.
# Default: false
Description:
Returns exit code 0 or 1, indicating whether or not the specified application
(pacticipant) has a successful verification result with each of the
application versions that are already deployed to a particular environment.
Prints out the relevant pact/verification details, indicating any missing or
failed verification results.
The can-i-deploy tool was originally written to support specifying versions
and dependencies using tags. This usage has now been superseded by first
class support for environments, deployments and releases. For documentation
on how to use can-i-deploy with tags, please see
https://docs.pact.io/pact_broker/client_cli/can_i_deploy_usage_with_tags/
Before `can-i-deploy` can be used, the relevant environment resources must
first be created in the Pact Broker using the `create-environment` command.
The "test" and "production" environments will have been seeded for you. You
can check the existing environments by running `pact-broker
list-environments`. See
https://docs.pact.io/pact_broker/client_cli/readme#environments for more
information.
$ pact-broker create-environment --name "uat" --display-name "UAT"
--no-production
After an application is deployed or released, its deployment must be recorded
using the `record-deployment` or `record-release` commands. See
https://docs.pact.io/pact_broker/recording_deployments_and_releases/ for more
information.
$ pact-broker record-deployment --pacticipant Foo --version 173153ae0
--environment uat
Before an application is deployed or released to an environment, the
can-i-deploy command must be run to check that the application version is
safe to deploy with the versions of each integrated application that are
already in that environment.
$ pact-broker can-i-deploy --pacticipant PACTICIPANT --version VERSION
--to-environment ENVIRONMENT
Example: can I deploy version 173153ae0 of application Foo to the test
environment?
$ pact-broker can-i-deploy --pacticipant Foo --version 173153ae0
--to-environment test
Can-i-deploy can also be used to check if arbitrary versions have a
successful verification. When asking "Can I deploy this application version
with the latest version from the main branch of another application" it
functions as a "can I merge" check.
$ pact-broker can-i-deploy --pacticipant Foo 173153ae0 \ --pacticipant Bar
--latest main
##### Polling
If the verification process takes a long time and there are results missing
when the can-i-deploy command runs in your CI/CD pipeline, you can configure
the command to poll and wait for the missing results to arrive. The arguments
to specify are `--retry-while-unknown TIMES` and `--retry-interval SECONDS`,
set to appropriate values for your pipeline.
