Burdened Acrobat
Overview
burdened-acrobat helps identity specific load balancers (or groups of load
balancers), when you have an unreasonable number of them. It does this by
treating the problem as one of set membership.
Why does this exist?
Some orchestration systems create large numbers of load balancers. Eventually,
this becomes unwieldy to manage. burdened-acrobat makes it simple again.
Installation
gem install burdened-acrobatUsage
require 'burdened-acrobat'
load_balancers = BurdenedAcrobat::LoadBalancers.new
load_balancers.search do
tagged('KubernetesCluster') & with('subnet-abv123') & tagged('kubernetes.io/service-name', 'app/identity-service')
endburdened-acrobat operates on two main sets of information: Load Balancers, and Tags.
Tags
LoadBalancers#tags returns tags.
| Given these Arguments | Expect to get a collection of… |
|---|---|
| None | All tags |
| A tag name | All tags matching that name |
| A tag name, and a value | All tags matching that name and value |
| A collection of load balancers | The tags on those load balancers |
Load Balancers
LoadBalancers#tagged returns load balancers.
| Given these arguments | Expect to get a collection of… |
|---|---|
| None | All load balancers with tags |
| A tag name | All load balancers with the given tag |
| A tag name, and a value | All load balancers where the given tag matches the value |
| A collection of tags | All load balancers matching those tags |
Everything!
LoadBalancers#all returns all load balancers.
Names
LoadBalancers#names accepts tags or load balancers, and returns names.
Using Names
LoadBalancers#named accepts names, and returns load balancers.
Complex Searches
Everything returned is in the form of Sets. This allows building complex
filters using #intersection, #union, #difference, and so on.
AWS-specific extras
When using Amazon ELBs, burdened-acrobat provides additional filters.
-LoadBalancers#with~ returns load balancers.
| Given these arguments | Expect to get a collection of |
|---|---|
| A VPC | All load balancers in that VPC |
| A security group | All load balancers using that security group |
| A subnet | ALl load balancers using that subnet |
