To run examples, run this command: ```shell python -m examples.example1 ``` (replace example1 with one of the filenames in the examples folder) ## Documentation All APIs and Models' documentation can be found at the [Generated client's README file](kubernetes/README.md) ## Compatibility `client-python` follows [semver](http://semver.org/), so until the major version of client-python gets increased, your code will continue to work with explicitly supported versions of Kubernetes clusters. #### Compatibility matrix | | Kubernetes 1.9 | Kubernetes 1.10 | Kubernetes 1.11 | Kubernetes 1.12 | Kubernetes 1.13 | Kubernetes 1.14 | Kubernetes 1.15 | |--------------------|----------------|-----------------|-----------------|-----------------|-----------------|-----------------|-----------------| | client-python 5.0 |✓ |- |- |- |- |- |- | | client-python 6.0 |+ |✓ |- |- |- |- |- | | client-python 7.0 |+ |+ |✓ |- |- |- |- | | client-python 8.0 |+ |+ |+ |✓ |- |- |- | | client-python 9.0 |+ |+ |+ |+ |✓ |- |- | | client-python 10.0 |+ |+ |+ |+ |+ |✓ |- | | client-python 11.0 |+ |+ |+ |+ |+ |+ |✓ | | client-python HEAD |+ |+ |+ |+ |+ |+ |✓ | Key: * `✓` Exactly the same features / API objects in both client-python and the Kubernetes version. * `+` client-python has features or api objects that may not be present in the Kubernetes cluster, but everything they have in common will work. * `-` The Kubernetes cluster has features the client-python library can't use (additional API objects, etc).

Kubernetes supports [three minor releases](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/release/versioning.md#supported-releases-and-component-skew) at a time. "Support" means we expect users to be running that version in production, though we may not port fixes back before the latest minor version. For example, when v1.3 comes out, v1.0 will no longer be supported. In consistent with Kubernetes support policy, we expect to support **three GA major releases** (corresponding to three Kubernetes minor releases) at a time. Note: There would be no maintenance for alpha/beta releases except the latest one. ## Community, Support, Discussion If you have any problem on using the package or any suggestions, please start with reaching the [Kubernetes clients slack channel](https://kubernetes.slack.com/messages/C76GB48RK/), or filing an [issue](https://github.com/kubernetes-client/python/issues) to let us know. You can also reach the maintainers of this project at [SIG API Machinery](https://github.com/kubernetes/community/tree/master/sig-api-machinery), where this project falls under. ### Code of Conduct Participation in the Kubernetes community is governed by the [CNCF Code of Conduct](https://github.com/cncf/foundation/blob/master/code-of-conduct.md). ## Troubleshooting ### SSLError on macOS If you get an SSLError, you likely need to update your version of python. The version that ships with macOS may not be supported. Install the latest version of python with [brew](https://brew.sh/): ``` brew install python ``` Once installed, you can query the version of OpenSSL like so: ``` python -c "import ssl; print ssl.OPENSSL_VERSION" ``` You'll need a version with OpenSSL version 1.0.0 or later. ### Hostname doesn't match If you get an `ssl.CertificateError` complaining about hostname match, your installed packages does not meet version [requirements](requirements.txt). Specifically check `ipaddress` and `urllib3` package versions to make sure they met requirements in [requirements.txt](requirements.txt) file. ### Why Exec/Attach calls doesn't work Starting from 4.0 release, we do not support directly calling exec or attach calls. you should use stream module to call them. so instead of `resp = api.connect_get_namespaced_pod_exec(name, ...` you should call `resp = stream(api.connect_get_namespaced_pod_exec, name, ...`. Using Stream will overwrite the requests protocol in _core_v1_api.CoreV1Api()_ This will cause a failure in non-exec/attach calls. If you reuse your api client object, you will need to recreate it between api calls that use _stream_ and other api calls. See more at [exec example](examples/pod_exec.py).
