Projects and quota

Creating a project

Click the blue "Create Project" button to create a project, and you will be presented with the following view:

OpenShift new project dialog

  1. You need to pick a unique name that is not in use by any other project in the system.
  2. You can also enter a human-readable display name and.
  3. You have to also enter a CSC computing project in the Description field. It must be a currently valid CSC project, that your account has access to. In order to view to which CSC projects you have access to, please check https://my.csc.fi. If you have access to no CSC project, you will not be able to create any Rahti project. If you have Rahti access via project_1000123, you would enter the following in the Description field:

csc_project: 1000123

You can also enter other text in the description field if you want to have a human-readable description for the project you are creating. In that case the field could look like this:

This project is used for hosting the Pied Piper web application.

csc_project: 1000123

See the section about accounts.

Once you have filled in the fields, click Create, and you will see the application catalog where you can pick an application template or import your own one.

For more information about using the web interface, refer to the official OpenShift documentation. You can find out which version of the documentation to look at in the web interface by clicking the question mark symbol in the top bar and selecting "About".

Extra information about CSC computing projects in Rahti

Projects in OpenShift are separate from CSC computing projects. A single CSC computing project can have access to multiple projects in OpenShift. Each CSC computing project with access to Rahti receives a group in OpenShift.

Note

Rahti can be used free of charge for open research and education in Finnish universities and polytechnics.

Any usage within OpenShifts projects are billed to the billing unit quota of the CSC project selected. Note that the selected CSC project must have Rahti access and the user creating a project must be a member of that computing project, otherwise the OpenShift project creation will fail.

  • If you would like to know which CSC computing projects you are a member of, you can view a list in the My Projects tool of MyCSC. You can also set a default billing project by going to Your Profile page. Select the project you would like to have as your default billing project and click on "Save". After doing this, the default billing project will be selected as the billing project for OpenShift projects if you do not explicitly specify one.

  • If you would like to know which CSC computing project an OpenShift project is associated with, you can do so using the oc command line tool. You can find instructions for setting up oc in the command line tool usage instructions . For example, if your OpenShift project is called my-openshift-project, you would run:

oc get project my-openshift-project -o yaml | grep csc_project

This should produce the following output:

    csc_project: "1000123"

In this case, the project is 1000123. Unfortunately, this information is not available via a web interface.

Note

It is not possible for normal users to change the csc_project label after a project has been created. If you would like to change the label for an existing project, please contact the support. You can also create a completely new project if you want to use a different label.

Note

It is possible to change the description of a project, but it will not change the csc_project label.

Project quotas

Two kinds of quota are applied in OpenShift:

  • Total number of projects per user
  • Resources created inside a project

By default, users can create up to five projects. Each of them has its own quota for the following resources:

Resource Default
Pods 20
Virtual cores per pod 2
Virtual cores per container 2
RAM per pod 8 GiB
RAM per container 8 GiB
Storage 50 GiB
Number of image streams 10
Size of each registry images 5 GiB

You can find the resource usage and quota of a project in the project view in the web interface under Resources -> Quota. Alternatively, you can use the oc command line tool:

oc describe quota
oc describe limitranges

If you need to create more projects or you need more resources in a project for your application, you can apply for more quota by contacting the Rahti support. See the Contact page for instructions. Quota requests are handled on a case-by-case basis depending on the currently available resources in Rahti and the use case.

Sharing projects with other users

OpenShift has a flexible role-based access control system that allows you to give access to projects you have created to other users and groups in the system. You can give e.g. full admin, basic user, edit or read only access to other users and groups in the system for collaboration.

You can edit project memberships in the web interface via Resources -> Membership. You can either give access rights to individual users or groups by selecting either the Users or Groups tab and clicking Edit Membership in the top right corner.

Note that it is important to use correct usernames when sharing projects with others. OpenShift allows you to freely enter any username and will not notify you for having entered a non-existent username. Usernames are also case-sensitive. You can find out your username in OpenShift via either the web interface or the command line:

  1. In the web interface, click the question mark symbol in the top bar and select "Command Line Tools". You can find your username above the text box that has the login command.
  2. If you have an active command line session, you can use the command oc whoami.

If you would like to share a project you have created with members of the same CSC computing project, you can do so by selecting the Groups tab, clicking Edit Membership, and entering the name of the computing project and a role in the dropdown menu on the right for the members of that computing project.

Deleting a Rahti project

In order to delete a Rahti project, you need to go to the main landing page and click in the 3 vertical dots next to the name of the project. In the drop down menu, you will see the option "Delete Project".

Remove Rahti drop down

Before the Rahti project is removed, you will be asked to input the name of the project to confirm that you really want to remove the Rahti project and prevent accidents.

Warning

After the project has been confirmed for deletion, all resources will be deleted and there will be no way to restore them, including the data stored in the persistent volumes.

Project name dialog

After that, Rahti will start to delete all the resources of the project. It could take only few seconds or up to a minute, it depends of amount of resources the project had. After that Rahti will liberate the project name, and it will be possible to create an empty project with the same name.
