Variables

Container Environment Variables

The Variables tab allows you to view and manage environment variables for the selected container layer. You can add custom variables, edit supported values, remove unnecessary records and apply the changes across the layer.

Variables Overview

Open the container settings and select the Variables tab to review all environment variables assigned to the current layer. These values can be used by applications and services running inside the containers.

ValueThe data assigned to the variable.
AddCreates a new custom environment variable.
EditChanges the selected variable when modification is allowed.
RemoveDeletes selected custom variables.

Variables from Linked Containers

When container linking is configured, variables received from other nodes in the same environment are also displayed in the Variables tab. Linked variables use a special prefix so they can be identified separately from local variables.

Linked values can be updated directly from this interface. The platform automatically applies the changed values to the related source and target containers.

Common Issues and Solutions

Variable is not savedConfirm that both the row-level save action and the layer-level Apply action were completed.
Name is rejectedRemove spaces and unsupported characters. Use only letters, numbers and underscores.
Edit option is unavailableThe selected record may be a protected platform variable.
Application does not detect the valueVerify the exact variable name, restart or redeploy the application when required, and confirm that the value was applied to the correct layer.
Unexpected changes on another nodeCheck whether the variable belongs to a linked container and review all related source and target nodes.
