red-hat-assisted-installer

Python package to implement the RedHat Assisted Installer API.

Description

Python package that implements the RedHat Assisted Installer API. This

Installation

pip install redhat-assisted-installer

Package Requirements

Packages

pip install requests

Environment Variables

• REDHAT_PULL_SECRET: The pull secret associated with your RedHat Hybrid Cloud account

• REDHAT_OFFLINE_TOKEN: The offline token associated with your RedHat Hybrid Cloud account

You can find these credentials by navigating to https://console.redhat.com/openshift/overview. In the side panel navigate to Downloads, and at the bottom of the page you should see the pull secret and token

How to use

Create AssistedInstaller instance

# import package
import redhat_assisted_installer.assistedinstaller as assistedinstaller

# Method 1:
# set assisted installer token value as an evironment variable
os.environ['REDHAT_OFFLINE_TOKEN'] = <str> token
# set assisted installer pull_secret value as an evironment variable
os.environ['REDHAT_PULL_SECRET'] = <str> pull_secret

# Method 2:
# You can also set env in virtual environment `activate` file via export.. you may have to restart your session
# export REDHAT_OFFLINE_TOKEN= '<token>'
# export REDHAT_PULL_SECRET= '<pull_secret>'

# create installer instance
installer = assistedinstaller.assistedinstaller()

On init the class will lookup the environment variables specified in requirements, and attempt to set those as attributes of itself.

API ENDPOINTS Implemented

/v2/clusters

GET

Retrieves the list of OpenShift clusters.

Query Parameters

name	type	description	required
openshift_cluster_id	string	A specific cluster to retrieve.	False
with_hosts	boolean	Include hosts in the returned list.	False
owner	string	returns only clusters that are owned by the specified user.	False

EXAMPLES

import redhat_assisted_installer.assistedinstaller as assistedinstaller

installer = assistedinstaller.assistedinstaller()

# return all clusters associated with this account
clusters = installer.getClusters()

# return cluster by id... still returns an array so remember to access via index (i.e clusters[0])
clusters = installer.getClusters(cluster_id=<cluster_id>)

# return all clusters and include the hosts associated with each cluster
clusters = installer.getClusters(with_hosts=True=<bool>)

POST

Creates a new OpenShift cluster definition.

Body Parameters

name	type	description	required
name	string	Name of cluster definition.	True
version	string	OpenShift version to use.	True
basedomain	string	The base dns domain to use for the cluster.	True
hamode	string	Determine if the cluster will be single node or highly available	False
cpuarchitecture	string	The cpu arch of the baremetal hardware this cluster will run on	False

EXAMPLES

import redhat_assisted_installer.assistedinstaller as assistedinstaller

installer = assistedinstaller.assistedinstaller()

# create a single node openshift cluster running version 4.15  
cluster = installer.postCluster("ocp-testing-sno", "4.15", "example.com")

# create a highly available cluster running 3 control plane nodes
cluster = installer.postCluster("ocp-testing-ha", "4.15", "example.com", hamode="Full")

/v2/clusters/{cluster_id}

DELETE

Deletes an OpenShift cluster definition.

Path Parameters

name	type	description	required
cluster_id	string	The cluster to be deregistered.	True

EXAMPLES

import redhat_assisted_installer.assistedinstaller as assistedinstaller

installer = assistedinstaller.assistedinstaller()

# get cluster by id
clusters = installer.getClusters(cluster_id=<cluster_id>)

# return object is an array, so we can safely delete any clusters with that id by using a for loop
for cluster in clusters:
    installer.deleteCluster(cluster['id'])

/v2/infra-envs

GET

Retrieves the list of infra-envs.

Query Parameters

name	type	description	required
cluster_id	string	returns only infra-envs which directly reference this cluster.	False
owner	string	returns only clusters that are owned by the specified user.	False

EXAMPLES

import redhat_assisted_installer.assistedinstaller as assistedinstaller

installer = assistedinstaller.assistedinstaller()
# get all infra-envs registered to this account
infra_envs = installer.getInfrastructureEnvironments()

# get all infra-envs registered to this account
infra_envs = installer.getInfrastructureEnvironments()

# get all infra-envs that directly reference cluster_id
infra_env = installer.getInfrastructureEnvironments(cluster_id=<cluster_id>)

POST

Creates a new OpenShift Discovery ISO.

Body Parameters

name	type	description	required
name	string	Name of cluster definition.	True
version	string	OpenShift version to use.	False
cluster_id	string	The cluster this infra-env will reference	False
cpuarchitecture	string	The cpu arch of the baremetal hardware this cluster will run on	False

EXAMPLES

import redhat_assisted_installer.assistedinstaller as assistedinstaller

installer = assistedinstaller.assistedinstaller()

# create min infra-env
installer.postInfrastructureEnvironment(name="testing-infra")

/v2/infra-envs/{infra-env-id}

DELETE

Deletes an infra-env.

Path Parameters

name	type	description	required
infra_env_id	string	The infra-env to be deleted.	True

EXAMPLES

import redhat_assisted_installer.assistedinstaller as assistedinstaller

installer = assistedinstaller.assistedinstaller()

# get all infra-envs registered to this account
infras = installer.getInfrastructureEnvironments()

# return object is an array, so we can safely delete any infra-envs with that id by using a for loop
for infra in infras:
    installer.deleteInfrastructureEnvironment(infra['id'])
