openshift-rest-client

Openshift Client

Node.js based client for the Openshift REST API, not unlike the Fabric8 Maven Plugin, but for node clients/builds.

Basic Usage

npm install --save openshift-rest-client

Code:

const openshiftRestClient = require('openshift-rest-client').OpenshiftClient;

openshiftRestClient().then((client) => {
  // Use the client object to find a list of projects, for example
  client.apis['project.openshift.io'].v1.projects.get().then((response) => {
    console.log(response.body);
  });
});

The openshift-rest-client translates Path Item Objects [[1]] (e.g., /apis/project.openshift.io/v1/projects) to object chains ending in HTTP methods (e.g., apis['project.openshift.io'].v1.projects.get).

So, to fetch all Projects:

const projects = await client.apis['project.openshift.io'].v1.projects.get()

The openshift-rest-client translates Path Templating [[2]] (e.g., /apis/build.openshift.io/v1/namespaces/$NAMESPACE/buildconfigs) to function calls (e.g., apis['build.openshift.io'].v1.namespaces('default').buildconfigs).

So, to create a new Build Config in the default Namespace:

const buildConfig = require('./build-config.json')
const create = await client.apis['build.openshift.io'].v1.namespaces('default').buildconfigs.post({ body: buildConfig })

and then fetch your newly created Build Config:

const deployment = await client.apis['build.openshift.io'].v1.namespaces('default').buildconfigs(buildConfig.metadata.name).get()

and finally, remove the Build Config:

await client.apis['build.openshift.io'].v1.namespaces('default').buildconfigs(buildConfig.metadata.name).delete()

The openshift-rest-client supports .delete, .get, .patch, .post, and .put.

There are also aliases defined, so instead of writing client.apis['build.openshift.io'], you can just use client.apis.build for example. The list of aliases can be seen here: https://github.com/nodeshift/openshift-rest-client/blob/master/lib/openshift-rest-client.js

Advanced Usage

By default, the openshift-rest-client will use the kubernetes-client module to get your configuration.

The openshift-rest-client exposes the config module from the kubernetes client for ease of use.

For example, if you want to provide a different path to your configuration, you can do something like this:

const openshiftRestClient = require('openshift-rest-client').OpenshiftClient;
const config = require('openshift-rest-client').config;

const path '~/some/path/config';
const customConfig = config.fromKubeconfig(path);

openshiftRestClient({config: customConfig}).then((client) => {
  // Use the client object to find a list of projects, for example
  client.apis['project.openshift.io'].v1.project.get().then((response) => {
    console.log(response.body);
  });
});

Changes in 2.0

The client has been totally rewritten for the 2.0 release. This includes a new, more fluent, API.

The old API will live in the 1.x branch.
