Optimizely runs four types of apps on OCP, all defined by the naming convention and the use of tags.
- Released apps – Apps released to production are available in the OCP App Directory.
- Private apps – Apps that are released to production, but their availability in the OCP App Directory is limited to one or more accounts.
- Beta apps – Apps that are not released to production but can be shared via private URLs for testing.
- Dev apps – Apps that are not released to production. These apps cannot be shared and are limited to running in the developer's associated ODP account.
This use case explains a dev app. Below is a brief introduction to the app naming convention and its use on the OCP platform.
We follow the Semantic Versioning (semver) specification of version management for apps built on the OCP platform.
All of our apps follow the semver.org standards. Given a version number MAJOR.MINOR.PATCH, we increment:
- The MAJOR version when you make an incompatible API change
- The MINOR version when you add functionality in a backward-compatible manner
- The PATCH version when you make backward-compatible bug fixes
We also support two types of pre-release tags:
-dev. Any app with a pre-release tag is not globally visible inside the app directory and is intended to serve as a work in progress.
The versioning of your OCP app is in the following format:
-devidentifies your build as pre-release
.VERSIONis the pre-release incrementor
Pre-release versioning allows you to work on a single train of code that is consistently named MAJOR.MINOR.PATCH, where you increment the pre-release tag as necessary until you are ready for your production release.
For example, imagine your next OCP app release is 2.1.9. During your development work, you end up with four pre-release versions before you are ready for the final release. Your versioning would look like this:
- 2.1.9-dev.1 - This is your first pre-release version
- 2.1.9_dev.2 - This is your second pre-release version
- 2.1.9_dev.3 - This is your third pre-release version
- 2.1.9_dev.4 - This is your fourth pre-release version
- 2.1.9 - This is your release version
The pre-release tag and versioning allows you to modify your release without incrementing the MAJOR, MINOR or PATCH numbers. Your release ID remains consistent while you work on your code, only incrementing the pre-release tag as you work.
Developers can only publish
-dev pre-release tags. The
-dev tag allows you to work in a sandbox environment without formal code review and without the ability to impact other apps, users, and accounts. These apps are hidden from the App Directory, so other users cannot see or use your apps.
app.ymlfile for your app on your local machine. Increment the pre-release version to
.2and save your changes. In our example from Initialize your first app:
In the OCP CLI, run the following command to validate, package, upload, and build your
.2 versionapp to prepare for publication:
opti app prepare
Once complete, use publish your new app. In this example,
opti directory publish <appversion>
Your app running in your ODP production account is automatically upgraded to the new app version. You can see this by navigating to the App Directory and clicking the app tile. The current version of your app displays:
