create_elb(name, zones, listeners=None, subnets=None, groups=None)[source]¶

Create an ELB named <name>

Parameters:	name (string) – The mnemonic name associated with the new load balancer zones (list of strings) – The names of the availability zone(s) to add listeners – Each tuple contains three or four values:

LoadBalancerPortNumber and InstancePortNumber are integer values between 1 and 65535;
Protocol is a string containing ‘TCP’, ‘SSL’, ‘HTTP’, ‘HTTPS’;
SSLCertificateID is the ARN of a AWS AIM certificate, and must be specified when doing HTTPS

Parameters:	subnets (list of strings) – A list of subnet IDs in your VPC to attach to your LoadBalancer groups (list of strings) – The security groups assigned to your LoadBalancer within your VPC

Parameters:	name (string) – The load balances name instance_id (string) – EC2 instance id startwith ‘i-xxxxxxx’
Return type:	boolean or string
Returns:	False or out of service reason

get_elb_id(name)[source]¶

Get Load Balancer Hosted Zone ID

Parameters:	name (str) – The load balances name
Return type:	str

parse_listeners(listeners)[source]¶

Parse elb listeners form list of string to list of tuple

Parameters:	listeners (list of string) – Listeners of this elb
Returns:	The list of listeners tuple
Type:	list of tuple

remove_elb_listeners(name, listeners)[source]¶

Remove a Listener (or group of listeners) for an existing Load Balancer

Parameters:	name (string) – The name of the load balancer to create the listeners for listeners (List int) – Each int represents the port on the ELB to be removed

set_elb_listeners(name, listeners)[source]¶

Create a Listener (or group of listeners) for an existing Load Balancer

Parameters:	name (string) – The name of the load balancer to create the listeners for listeners – Listener to be setted

set_health_check(name, health_check)[source]¶

Configures the health check behavior for the instances behind this load balancer.

Parameters:	name (string) – The mnemonic name associated with the load balancer health_check (boto.ec2.elb.healthcheck.HealthCheck) – A HealthCheck instance that tells the load balancer how to check its instances for health.
