the Username, Enter your robot accounts token as the password, You can learn more about the Harbor project on the official website: Currently, we support Google and Microsoft as OIDC providers. environments like Rancher/Anvil. We can also configure this via the command line if we want to automate setup with a configuration management tool such as Chef or Ansible. The Docker and Helm CLIs cannot handle redirection for OIDC, so Harbor provides A complete overview of all Harbor configuration options is available at the official Harbor helm chart documentation. Usually, you should proceed with this tutorial only after youve set up everything in your account in the providers cloud. It can be achieved by adding the memberof attribute to every ID token, similarly to how it is done in case of LDAP/AD authentication. Harbor is a Cloud Native Computing Foundation (CNCF)project that provides a self-hosted, cloud-native registry for storing, signing, and scanning container images. It is because I disabled Harbor internal TLS in favor of the Istio proxy sidecar that enforces mTLS for each Harbor service. Integrating Harbor with Istio is mostly about setting up proper URI routing. After you have authenticated via OIDC and logged into the Harbor interface for The container image registry, provided by Harbor, and Docker CLI do not support the OIDC protocol. After installing the helm chart into the cluster, wait until all Harbor pods and certificates are Ready: Now, Harbor should be up and running under your configured URL: Congratulations, you now have a fully working Harbor instance! CLI secrets provide end users with a token to access Harbor via Docker or Helm clients. The fully-featured version is composed of ten micro-services. As an example we can then as an admin user, create a private project called "test1", then head to the "Members" tab of this project and choose "+ Group". Learn how cloud architectures help organizations take care of application and cloud security, observability, availability and elasticity. If you misconfigured anything, you can just click on the Harbor button again and change the values. We should not create any regular users because we can only switch to OIDC based login if no users other than admin have been created. In Harbor, a user can log in by performing an OIDC authentication code flow with Keycloak. Attend QCon San Francisco (Oct 24-28) and find practical inspiration from software leaders.

So to set up OIDC auth via CLI we can use: A 200 response indicates that we have Succesfully setup Keycloak auth. It is because sub and/or iss scopes from ID token may change, so the same user trying to login to the harbor dashboard will be treated as a new one. Attend in-person on Oct 24-28, 2022. Users CLI secrets can be set to expire after a while as expained here. You need to Register an InfoQ account or Login or login to post comments. We can then tag an image to be pushed to this repository with: When we need to give things like CI servers or Kubernetes access to the repository, we can head to the "Robot Accounts" tab in Harbor to generate limited access tokens for exactly this. The command below should login to harbor docker registry successfully. Here we should login with a regular Keycloak user from the realm we're using (by default master), NOT our keycloak admin user. Harbor is an open source registry which can serve multiple types of cloud artifacts and secure them using fine grained access control. Attend QCon San Francisco (Oct 24-28) and find practical inspiration from software leaders. Login harbor with OIDC and harbor will create a user automatically. We do it either by using a declarative approach when that is possible, or else by interacting with their (REST) APIs directly. Instead, you can use Harbor robot accounts that do not depend on OIDC authentication. In this post we'll install a feature rich but lightweight docker registry and integrate login and authorization with Keycloak users and groups. Privacy Notice, Terms And Conditions, Cookie Policy. Attempting to login into the Docker registry will end up with an "authentication required" error. As a system admin, you will continue to use your old credentials and Username and Password field to access your instance. privacy statement. You can change the authentication mode from database to OIDC only if no local users have been added to the database. I recommend creating two robot accounts in each Harbor project. InfoQ Homepage a CLI secret for use when logging in from Docker or Helm. The Harbor robot accounts are made for that purpose. Create an OAuth2/OpenID provider with the following parameters: Note the Client ID and Client Secret values. If we now log back in as our admin user and go to "Administration" and "Groups" we'll see that any Keycloak groups the user was a member of have now been replicated into Harbor. Topics include capacity and workload management, security integration, and homegrown PaaS integration. The drawer should open, where you are now able to configure Harbor. Replication can be done to other registries as required, having them act as pure content repositories. since this is a multi-tenant registry, harbor does this to avoid unrelated For Keycloak, we have automated configuration of the external identity provider, group names normalization, deriving Client ID, Client Secret and more. An equal access/equal opportunity university. It makes it possible for the Istio Ingress gateway to route the incoming traffic. This release includes an OpenID Connect integration, the addition of robot accounts, and improvements to the replication features, among other improvements. In this case we'll be focussed on using harbor as a docker image registry and linking it's authentication with Keycloak but it is also capable of serving multiple other types of artifact, including helm charts. The group claim name is crucial for enabling Harbor OIDC group matching. As with most helm charts, we learn a lot by inspecting the values file which can be found here. See the next chapter to learn how to configure Harbor to handle authentication through Loft. The client id is Otomi and the client secret is defined in the credentials tab. Interestingly the community of Harbor users is having a broad debate about using OIDC protocol and could not agree on a final solution so far. In Loft, Harbor can be installed as an App and Loft users can log in to Harbor via Loft or your configured external authentication provider in Loft. If you want to perform an automatic user onboarding process you should provide the following OIDC scopes: OpenID (iss and sub-properties) and email scope (email and email_verified properties). OIDC User cannot login to docker registry with generated CLI password. There are ways to adapt to digital transformation and establish well-functioning DesignOps. The ID token is issued by the Keycloak (iss property) that is running in the same Kubernetes cluster. create, the old one becomes invalid. For example, the OIDC group team-demo is a member of a team-demo project. $ docker login registry.anvil.rcac.purdue.edu, Push your image to your project registry The good news is that if you are an automation freak like me, you don't actually need CLI secrets. Information for setting up the client on keycloak side can be found on the red hat docs page, As Admin, go to Administration -> Configuration -> Authentication. Besides, make sure that you made yourself familiar with general notes on different authentication modes as each of them may have its advantages and disadvantages. Well occasionally send you account related emails. Understand the emerging software trends you should pay attention to. I hope that this article provides you a good insight into more advanced Harbor integration in the Kubernetes cluster. By creating projects you can achieve a multi-tenant container image repository for workloads in your Kubernetes cluster. We can then enter /Administrators as the Group Name and choose "Project Admin" as the role. automatically generating or manually creating a new CLI secret. Meet CockroachDB Serverless - The most highly evolved SQL database on the planet. OIDC configuration has to be done post installation and can either be done using the HTTP API or the web UI.

We could then restrict project creation to admins only with: The Habor API is comprehensive e.g. Please dont include any personal information in your comment. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. To bypass this, use the Anvil cache url To access Harbor in the cluster, you will need to deploy an ingress controller (if you don't already have one) and the cert-manager for creating a tls certificate. It takes a while for the various components to start and it's not unusual to see a few pods in CrashLoopBackoff temporarily while this is happening. Optionally click the icon in your user profile to display buttons for Please provide the steps to reproduce this problem. This is my story about building a multi-tenant Kubernetes environment that facilitates various DevOps teams (tenants) with their own Kubernetes namespace and private container registry (Harbor v2.1.0) with Single-Sign-On On (Keycloak v10.0.0) and service mesh (Istio 1.6.14) included. https://your-custom-domain.com/c/oidc/callback. Start Instantly. Please double check if the OIDC provider does return the refresh token and it supports refreshing the token. With this feature, Harbor can act as a central repository for all images. Administrators can now use an OIDC provider as the authentication model for users. Join a community of over 250,000 senior developers. To configure Loft as an OIDC provider, you can edit the Loft config in the Loft UI: Use the following values to allow Harbor to connect to Loft: After you have changed the Loft config, head over to Harbor and change the AuthMode in Administration -> Configuration to OIDC: Make sure the field OIDC Endpoint is set to your Loft instance URL with the path /oidc. A robot account and token can be used to authenticate to your registry in place Do not forget about Keycloak, which requires an additional configuration of the OIDC client. Harbor is open source and releases are available on their GitHub page. means if youre trying to deploy a workload, or have a currently deployed In the User Guides section, you can find selected configuration tutorials that explain how the settings look like on the provider side. As it is self-hosted, it is also an option for providing a consistent experience for a multi-cloud strategy. If your organization decides to migrate users to another identity provider you may experience a duplicated user error: "Conflict, the user with the same username or email has been onboarded". XSEDE account username and password, From the main page click create project, this will act as your registry, Fill in a name and select whether you want the project to be public or private, Tag your image Becoming an editor for InfoQ was one of the best decisions of my career. You can do this by deploying the predefined apps nginx-ingress, cert-manager and cert-issuer (you will only need to deploy those, if the connected cluster is NOT the cluster that Loft is installed in): Once you have an ingress controller and cert-manager running, click on the Harbor Icon. A workaround is re-login Harbor via the SSO flow and so the new token will be associated with CLI secret. the Docker or Helm CLI. Here, I share just a few Issues that I stumbled upon.
