create_balancer(name, port, protocol, algorithm, members, ex_scheme=None, ex_security_groups=None, ex_subnets=None, ex_tags=None, ex_ssl_cert_arn=None)[source]¶

Create a new load balancer instance.

AWS ALB balancer creation consists of 5 steps: http://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/Welcome.html

create_balancer() is a standard API method so, it’s made as a wrapper here to preserve compatibility with other drivers where LB creation is one-step process. It calls respective ALB methods to assemble ready-to-use load balancer.

Parameters:

name (str) – Name of the new load balancer
port (int) – Port number to setup load balancer listener
protocol (str) – Load balancer protocol, should be ‘HTTP’ or ‘HTTPS’.
algorithm (Algorithm or None) – Load balancing algorithm. Ignored for AWS ALB.
members (list of Member) – List of Members to attach to the balancer. If ‘port’ attribute is set for the memeber - load balancer will send traffic there. Otherwise - load balancer port is used on the memeber’s side. ‘ip’ attribute is ignored.
ex_scheme (str) – Scheme of load balancer. Can be ‘internet-facing’ or ‘internal’.
ex_security_groups (list of str) – List of load balancer security group ids.
ex_subnets (list of str) – List of load balancer subnet ids.
ex_tags (dict) – Tags to assign to the load balancer.
ex_ssl_cert_arn (str) – SSL certificate ARN to use when load balancer protocol is ‘HTTPS’.

Returns:

LoadBalancer object

Return type:

LoadBalancer

ex_create_balancer(name, addr_type='ipv4', scheme='internet-facing', security_groups=None, subnets=None, tags=None)[source]¶

AWS-specific method to create a new load balancer. Since ALB is a composite object (load balancer, target group, listener etc) - extra methods must be called to assemble ready-to-use balancer.

Parameters:

name (str) – Name of the new load balancer
addr_type (str) – Load balancer address type. Can be ‘ipv4’ or ‘ipv6’.
scheme (str) – Scheme of load balancer. Can be ‘internet-facing’ or ‘internal’.
security_groups (list of str) – List of load balancer security group ids.
subnets (list of str) – List of load balancer subnet ids.
tags (dict) – Tags to assign to the load balancer.

Returns:

LoadBalancer object

Return type:

target_group (ALBTargetGroup) – Target group associated with the listener.
action (str) – Default action for the listener, valid value is ‘forward’
ssl_cert_arn (str) – SSL certificate ARN to use when listener protocol is ‘HTTPS’.
