Role Strategy plugin

About this plugin

The Role Strategy plugin is meant to be used from Jenkins to add a new role-based mechanism to manage users' permissions. Supported features

• Creating global roles, such as admin, job creator, anonymous, etc., allowing to set Overall, Agent, Job, Run, View and SCM permissions on a global basis.
• Creating item roles, allowing to set item specific permissions (e.g Job, Run or Credentials) on Jobs, Pipelines and Folders.
• Creating agent roles, allowing to set agent specific permissions.
• Assigning these roles to users and user groups
• Extending roles and permissions matching via Macro extensions

Usage

Installing and enabling the plugin

The Role Strategy plugin can be installed from any Jenkins installation connected to the Internet using the Plugin Manager screen. Activate the Role-Based Strategy by using the standard Manage Jenkins > Configure Global Security screen:

After the installation, the plugin can be configured using the Manage and Assign Roles screen accessible from Manage Jenkins .

Configuring roles

You can define roles by using the Manages Roles screen. It is possible to define global, item and agent specific roles.

• Global roles apply to any item in Jenkins and override anything you specify in the Item Roles. That is, when you give a role the right Job/Read in the Global Roles, then this role is allowed to read all Jobs, no matter what you specify in the Item Roles. Giving Job/Create in a global role will allow to create jobs of any name.
• For item and agent roles you can set a regular expression pattern for matching items. The regular expression aimes at matching the full item name.
  • For example, if you set the field to Roger-.*, then the role will match all jobs which name starts with Roger-.
  • Patterns are case-sensitive. To perform a case-insensitive match, use (?i) notation: upper, Roger-.* vs. lower, roger-.* vs. case-insensitive, (?i)roger-.*.
  • Folders can be matched using expressions like ^foo/bar.*. To access jobs inside a folder, the folder itself must also be accessible to the user. This can be achieved with a single pattern like (?i)folder($|/.*) when the permissions on the folder can be the same as for the jobs. If different permissions need to be configured 2 different roles need to be created, e.g. (?i)folder and (?i)folder/.*. Note that job names inside folders are case-sensitive, though this is probably a bug in the folders plugin JENKINS-67695. Case sensitivity can be enabled with (?-i), e.g. (?i)folder/(?-i).*
  • Create permissions on item level can only reliably work when the Naming Strategy is set to Role-Based strategy in the global configuration for Restrict project naming. You should see a warning in the administrative monitors if it is not enabled. Only jobs matching the pattern can be created. When granting Job/Create you should also grant Job/Configure and Job/Read otherwise you will be able to create new jobs but you will not be able to configure them. Global Permissions are not required.

Permission Templates

Permission Templates simplify the administration of roles when you need to maintain many roles with identical permissions but different patterns. Templates are only available for Item Roles. The permissions of roles based on a template can't be modified directly. Modifying the template will immediately modify the linked roles after saving the changes.

Deleting a template that is still in use requires confirmation. In case you still delete it, the roles stay with the given permissions but the correlation to the template is removed.

Assigning roles

You can assign roles to users and user groups using the Assign Roles screen

• User groups represent authorities provided by the Security Realm (e.g. Active Directory or LDAP plugin can provide groups)
• There are also two built-in groups: authenticated (users who logged in) and anonymous (any user, including ones who have not logged in)
• Hovering over the header row will show a tooltip with the permissions associated to the role and the pattern.
• Hovering over a checkbox will show a tooltip with role, user/group and pattern.

Getting roles in pipelines

There are 2 steps available in pipeline jobs that allow to get the roles of the user running the build. When the build was triggered by a user via the UI or the REST API, the roles of this user are returned. In case the build was triggered by the times or an SCM event there is no dedicated user available and the SYSTEM user is used. This user is considered like an admin and will have all roles.
With the Authorize Project plugin, it is possible to make builds triggered by timer or an SCM event to run as a specific user which is then used or run as anonymous. For anonymous it means no roles are returned. The user that triggered the build will always take precedence over the user that is configured via Authorize Project.

currentUserGlobalRoles

The step currentUserGlobalRoles will return all global roles of the user.

currentUserItemRoles

The step currentUserItemRoles will return the item roles of the user. By default, it returns only those roles that match the currently building pipeline. The parameter showAllRoles will return all item roles of the user.

Rest API

The Rest API allows to query the current roles and assignments and to do changes to them. Please see the javadoc for details and examples.

Config & Assign role by using Jenkins Script Console or Groovy Hook Script

Configuration management can be used via Jenkins Script Console or Groovy Hook Scripts, following example is creating an admin role & user based on plugin 3.1.

import com.michelin.cio.hudson.plugins.rolestrategy.AuthorizationType
import com.michelin.cio.hudson.plugins.rolestrategy.PermissionEntry
import com.michelin.cio.hudson.plugins.rolestrategy.RoleBasedAuthorizationStrategy
import com.michelin.cio.hudson.plugins.rolestrategy.Role
import com.synopsys.arc.jenkins.plugins.rolestrategy.RoleType
import hudson.security.Permission
import jenkins.model.Jenkins


Jenkins jenkins = Jenkins.get()
def rbas = new RoleBasedAuthorizationStrategy()

/* create admin role */
Set<Permission> permissions = new HashSet<>();
permissions.add(Jenkins.ADMINISTER)
Role adminRole = new Role("admin", permissions)

globalRoleMap = rbas.getRoleMap(RoleType.Global)
globalRoleMap.addRole(adminRole)
/* assign admin role to user 'admin' */
globalRoleMap.assignRole(adminRole, new PermissionEntry(AuthorizationType.USER, 'admin'))
/* assign admin role to group 'administrators' */
globalRoleMap.assignRole(adminRole, new PermissionEntry(AuthorizationType.GROUP, 'administrators'))
jenkins.setAuthorizationStrategy(rbas)

jenkins.save()

Case sensitive mode

In previous versions of this plugin, role assignments where always matched case-sensitive, even when the security realm works case-insensitive (as do most of them). As of version 685 the plugin will use the strategy given by the security realm to match assigned roles. If for some reason you need the old behaviour, set the property com.michelin.cio.hudson.plugins.rolestrategy.RoleMap.FORCE_CASE_SENSITIVE via command line jenkins -Dcom.michelin.cio.hudson.plugins.rolestrategy.RoleMap.FORCE_CASE_SENSITIVE=true -war jenkins.war, set it via the script console or via an init hook script.
