## About this plugin
The Role Strategy plugin is meant to be used from [Jenkins](https://jenkins.io) 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](./docs/MACROS.md)
## 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](https://issues.jenkins.io/browse/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](https://plugins.jenkins.io/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 `currentUserGlobalRoles` 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](https://javadoc.jenkins.io/plugin/role-strategy/com/michelin/cio/hudson/plugins/rolestrategy/RoleBasedAuthorizationStrategy.html) 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](https://www.jenkins.io/doc/book/managing/script-console/) or
[Groovy Hook Scripts](https://www.jenkins.io/doc/book/managing/groovy-hook-scripts/), following example is creating an admin role & user based on plugin 3.1.
```groovy
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 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.
