You will see all your environments associated with an application under the
You can customize your
Deployment template, ConfigMap, Secretsin Environment Overrides section to add separate customizations for different environments such as dev, test, integration, prod, etc.
If you want to deploy an application in a non-production environment and then in production environment, once testing is done in the non-production environment, then you do not need to create a new application for production environment. Your existing pipeline(non-production env) will work for both the environments with little customization in your deployment template under
In a Non-production environment, you may have specified 100m CPU resources in the deployment template but in the Production environment, you may want to have 500m CPU resources as the traffic on Pods will be higher than traffic on non-production env.
Configuring the Deployment template inside
Environment Overridesfor a specific environment will not affect the other environments because
Environment Overrideswill configure deployment templates on environment basis. And at the time of deployment, it will always pick the overridden deployment template if any.
If there are no overrides specified for an environment in the
Environment Overridessection, the deployment template will be the one you specified in the
deployment template sectionof the app creation.
(Note: This example is meant only for a representational purpose. You can choose to add any customizations you want in your deployment templates in the
Any changes in the configuration will not be added to the template, instead, it will make a copy of the template and lets you customize it for each particular environment. And now this overridden template will be used only for the specified Environment.
This will save you the trouble to manually create deployment files separately for each environment. Instead, all you have to do is to change the required variables in the deployment template.

The basic deployment configuration which you specified on the Basic GUI section will be visible for you to customize for your environment.

Advanced (YAML)which will be the default page.
Note: Delete Override will discard the current overrides and the base configuration will be applicable to the environment.
The same goes for
Secrets. You can also create an environment-specific configmap and Secrets inside the
If you want to configure your ConfigMap and secrets at the application level then you can provide them in ConfigMaps and Secrets, but if you want to have environment-specific ConfigMap and secrets then provide them under the Environment override Section. At the time of deployment, it will pick both of them and provide them inside your cluster.
