Canary Release

Canary release is a technique to reduce the risk of introducing a new software version in production by slowly rolling out the change to a small subset of users before rolling it out to the entire infrastructure and making it available to everybody.

This is the easiest rollout strategy available.
You just have to select a percentage of your users in your flag, and the True behavior will apply to them.

Example

YAML

canary-flag:
  true: true
  false: false
  default: false
  percentage: 1

JSON

{
  "canary-flag": {
    "true": true,
    "false": false,
    "default": "false,
    "percentage": 1
  }
}

TOML

[canary-flag]
true = true
false = false
default = false
percentage = 1.0
