Like each service in OpenStack, murano has its own role-based access policies that determine who and how can access objects. These policies are defined in the service’s policy.json file.
On each API call corresponding policy check is performed. policy.json file can be changed whiteout interrupting the API service.
For detailed information on policy.json syntax, please refer to the OpenStack official documentation
With this file you can set who may upload packages and perform other operations.
The policy.json example is:
{
// Rule declaration
"context_is_admin": "role:admin",
"admin_api": "is_admin:True",
"default": "",
// Package operations
"get_package": "rule:default",
"upload_package": "rule:default",
"modify_package": "rule:default",
"publicize_package": "rule:admin_api",
"manage_public_package": "rule:default",
"delete_package": "rule:default",
"download_package": "rule:default",
// Category operations
"get_category": "rule:default",
"delete_category": "rule:admin_api",
"add_category": "rule:admin_api",
// Deployment read operations
"list_deployments": "rule:default",
"statuses_deployments": "rule:default",
// Environment operations
"list_environments": "rule:default",
"list_environments_all_tenants": "rule:admin_api",
"show_environment": "rule:default",
"update_environment": "rule:default",
"create_environment": "rule:default",
"delete_environment": "rule:default",
// Environment template operations
"list_env_templates": "rule:default",
"create_env_template": "rule:default",
"show_env_template": "rule:default",
"update_env_template": "rule:default",
"delete_env_template": "rule:default",
// Control on executing actions on deployment environments
"execute_action": "rule:default"
}
So, changing "upload_package": "rule:default" to "rule:admin_api" will forbid regular users to upload packages.
For reference:
Uploading package wizard in murano dashboard consists of several steps. Upload package API call requested from the first form and modify from the second one. It provides modifying package parameters on time of uploading. So, please modify both configuration together. Otherwise it will not be possible to browse package details on the second step of the wizard.
