The Code elements of the Cloud PlatformEnvironments page provide a user interface for deploying code from your repository to your application's environments. When you commit a branch to your repository, Cloud Platform updates the environment that executes that code branch.
Make and test changes to administrative configurations, views, and other major application settings only in your non-production environments. Do not make or test changes in your production environment. If you make a change that breaks your application in the production environment, your live application may become unavailable.
To deploy code to an environment:
Check out your repository to your local machine.
Make changes to your application in the /master directory, or whatever branch you have configured to deploy for the development environment. Any environment that deploys a branch deploys all commits to that branch immediately.
Do not deploy the master branch on your production environment; code committed to master would then deploy immediately in your live application, before you have a chance to test it.
To change the code on your infrastructure, select one of the following methods:
Commit changes to the currently deployed branch.
Select a different repository branch or tag to deploy.
Clear Varnish cache. Clear caches on a production environment with caution, especially when the system is under load. Schedule Varnish cache clears during periods of low user activity to minimize impact.
To switch the code deployed in an environment from one tag or branch to another:
In the Code element for the environment, click the code switch button.
In the Switch code dialog box, select a tag or branch from the Select branch menu and click Continue. In the Switch code confirmation dialog box, click Switch.
When you select a new branch or tag to deploy, Cloud Platform retrieves code from your repository and deploys it to the appropriate environment on the infrastructure. The deploy task appears in the Activity task list.
Deploying code from the Environment Overview page
You can deploy code on an environment or copy code from one environment to another from the Overview page of the environment.
To switch the code deployed in an environment from one tag or branch to another:
On the Environments page, select an environment to view the corresponding Overview page.
In the Code section, click Switch.
In the Switch code dialog box, select a tag or branch from the Select branch menu and click Continue.
In the Switch code confirmation dialog box, click Switch.
Moving code from one environment to another
To move code from one environment to another, such as Dev to Stage or from Stage to Prod, use one of the following processes, depending on your location in the Cloud Platform interface:
From the Environments page
Drag a Code element from one environment to another environment. Cloud Platform creates a new tag for the head version of the branch (the most recently committed code version) and then deploys the tag in the environment you selected. For example, drag your Dev Code element to Stage.
Alternatively, you can add a commit message.
Click Deploy.
When you drag your Dev code container to the Stage environment, Cloud Platform creates a symbolic link between the Staging environment and the head version (the most recently committed code version) of trunk in your Development environment. When you click Deploy, Cloud Platform creates a tag and updates the infrastructure to that version of your code. The default tag format is yyyy‐mm‐dd.version (for example, tags/2016‐09‐18). From the example, the next tag you create is 2016‐09‐18.0.
When you have a version ready to deploy to your live production application, drag your code element from the Stage environment to Prod. If the staging environment is running a tag, that same tag is deployed into production.
From the Overview page of an environment
To copy code from one environment to another (creating and deploying a new tag) from the Overview page:
On the Environments page, click the name of the environment to open that environment’s Overview page.
On the Overview page for the environment, click .
Reverting code
To revert code to an earlier version:
In the Code element for the environment, click the code switch button.
In the Switch code dialog box, select the tag for the version to which you want to revert, and then click Continue.
In the Switch code confirmation dialog box, click Switch.
When you deploy a previous branch or tag, Cloud Platform retrieves the code snapshot from your repository and then deploys it on the appropriate environment on the infrastructure.
