Generate Bindings


  • Pulp 3 running on localhost:24817
  • Docker or Podman

Basic Usage

The script takes three positional arguments:

./ <module-name> <language> [<version>]  

When the optional version parameter is provided, it is used as the version string. When it is not provided, the version reported by Pulp's status API is used.

The final packages are stored in the {plugin_label}-client directory.


# Create Python Package in 'pulpcore-client/'.
# Uses API reported  version
sudo ./ pulpcore python

# Create Ruby Gem in 'pulp_rpm-client/'.
# Uses API reported version
sudo ./ pulp_rpm ruby

# Create Ruby Gem 'pulp_rpm-client/'.
# Uses '' version
sudo ./ pulp_rpm ruby

Special Cases

Re-Rooted Systems

During bindings generation the openapi schema is fetched. Use the PULP_API_ROOT environment variable to instruct the bindings generator where the root of the API is located. For example, the default export PULP_API_ROOT="/pulp/" is the default root, which then serves the api.json at /pulp/api/v3/docs/api.json.

Remote Systems

During bindings generation the openapi schema is fetched. Use the PULP_API environment variable to instruct the bindings generator to use a Pulp API on a different host and/or port. For example, export PULP_API="http://localhost:24817" are the default host and port, which results in the bindings generator talking to the Pulp API at http://localhost:24817/pulp/api/v3/docs/api.json.

Local Openapi Schema

If you want to use a locally present openapi schema, you can skip fetching the openapi schema by setting the USE_LOCAL_API_JSON environment variable. Doing so you have to manually provide the api.json file containing the openapi schema in the current working directory.

Docker in Docker (dind)

Bindings are generated using the openapi-generator-cli docker container. If your environment itself runs in a docker container, the openapi-generator-cli container has to be started as a sibling container. For sibling containers, volumes cannot be mounted as usual. They have to be passed through from the parent container. For this to work you have to set the PARENT_CONRAINER_ID environment variable to specify the parent container in a dind environment.

Filesystem Shared With Another Container

When the bindings are being generated so that they can be installed inside another container, it may be necessary to set the MCS label on the openapi-generator-cli container to match the MCS label of the other container. Users can set the $PULP_MCS_LABEL environment variable (e.g. s0:c1,c2). When this variable is present, the container for openapi-generator-cli will be started with this MCS label. This only applies to systems that are using podman and SELinux is Enforcing.
