kandi X-RAY | feature-toggle Summary
Continuous deployment is the process of testing, integrating, and deploying software in rapid cycles in order to deliver bug fixes and new features to customers as quickly as possible. It gained popular acceptance as a cornerstone of extreme programming and agile development. It is very popular among Software as a Service providers. A feature toggle system allows you to integrate features into your codebase even before they’re finished and ready to release. During development, the features are toggled off by default. In order to turn them on, you must enable them manually. Using this method, you can deploy unfinished or untested changes into your production system without interfering with the user experience. Feature toggles can allow software integration cycles that run in weeks, days, or even hours, as opposed to months or years. They are an essential component in a broader continuous integration system.

QUESTION
I am using terraform to create Kubernetes namespace. Sample below
...ANSWER
Answered 2021-Apr-11 at 23:25From the question it is not clear why you would require two provider definitions. But for the sake of example we can consider the below common use cases for blue/green deployment:
- target different clusters
- target different contexts
In both cases it will be easier to use a single provider with different provider configuration based on the flag set in variable.
Considering a variable definition like (using a string
type but a bool
can also be used):
QUESTION
I have been using 503 Service Unavailable or down for maintenance.
However some http client libraries i.e. axios treat 503 as retriable error.
It makes sense to retry it if the response is produced due to high load but 503 also fits the feature-toggle case.
Any suggestion on other codes people use ?
...ANSWER
Answered 2020-Mar-05 at 23:02Status codes are meta data that belong to the "transferring documents over a network" domain. Shared semantics of the status codes is what allows general-purpose HTTP aware components to act intelligently.
So what you should be doing is thinking about the HTTP semantics.
For example, if your server doesn't have access to a current representation of the resource identified by the target-uri of the request, then you should be issuing a 404 Not Found
response. If the request is forbidden, then 403 Forbidden
. Or 451 Unavailable for Legal Reasons
when that is the intended meaning.
In other words: it depends.
But what it doesn't depend on is "feature flag"; that's an implementation detail. The "uniform interface" is a facade that hides those sorts of technical details that vary from one implementation to another. From the outside, your API provides the illusion that your machine is just another boring web server.
