Support single availability zone on aws #689

Closed joe1chen closed 8 years ago

joe1chen commented 8 years ago

Allow subnets to be set from environment variables. This is required to support running in a single availability zone.

Currently if you try to run in a single az, you get an error with the ELB

Environment variables:

export TF_VAR_availability_zones=us-east-1a

Error:

aws_elb.elb: InvalidConfigurationRequest: ELB cannot be attached to multiple subnets in the same AZ.

With this pull request, you can successfully run in a single az by just setting both availability zone and subnets:

export TF_VAR_availability_zones=us-east-1a
export TF_VAR_public_subnets=10.0.1.0/24

BTW, why would I want to run in a single AZ? I'm trying to set up Flocker, which only supports a single AZ. If anyone has gotten this working please send me a message.

@joe1chen we have looked at flocker and had a chat to the team at clusterhq but alot of their setups for mesos and pure docker arent quite supported yet but this PR makes perfect sense
