Query Instance Group Lists
The following code is used to obtain instance group information based on cluster ID:
try:
response = bmr_client.list_instance_groups(cluster_id)
for instance_group in response.instance_groups:
LOG.debug('list instance groups %s: %s' % (instance_group.id, instance_group))
except BceHttpClientError as e:
if isinstance(e.last_error, BceServerError):
LOG.error('list_instance_groups failed. Response %s, code: %s, msg: %s'
% (e.last_error.status_code, e.last_error.code, e.last_error.message))
else:
LOG.error('list_instance_groups failed. Unknown exception: %s' % e)Modify Instance Group Configurations
BMR can modify the configuration of CORE and TASK nodes, and the example code is as follows:
try:
bmr_client.scale_cluster(cluster_id, instance_group_id, instance_count)
except BceHttpClientError as e:
if isinstance(e.last_error, BceServerError):
LOG.error('scale_cluster failed. Response %s, code: %s, msg: %s'
% (e.last_error.status_code, e.last_error.code, e.last_error.message))
else:
LOG.error('scale_cluster failed. Unknown exception: %s' % e)
