Environment Overrides
You will see all your environments associated with an application under the
Environment Overrides section.
You can customize your
Deployment template, ConfigMap, Secrets in 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
Environment overrides.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 Overrides for a specific environment will not affect the other environments because Environment Overrides will 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 Overrides section, the deployment template will be the one you specified in the deployment template section of 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
Environment Overrides tab)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.
In the
Environment Overrides section, click on Allow Override and make changes to your Deployment template and click on Save to save your changes of 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.
If you want to configure Basic GUI at the application level, then you can provide the required information in the Basic Configuration.
If
Basic is locked, you can modify the configurations on 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
ConfigMap and Secrets. You can also create an environment-specific configmap and Secrets inside the Environment override section.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.
