Sign in

Access your workloads through the GDC console or the gdcloud CLI.

To sign in to the GDC console or a cluster, work through the following steps:

Console

Open the following URL in a new browser tab to access the Distributed Cloud user interface (UI):

https://GDC_URL

Replace GDC_URL with the domain name you use to access Distributed Cloud that the Infrastructure Operator (IO) provides. When opening any URL for the first time, Distributed Cloud redirects you to your identity provider login page if the Infrastructure Operator (IO) configured the page.

For example, the following image signs in to the console UI for an organization named org-1:

CLI

You can sign in to any cluster that you have permission to access. The CLI login process differs between org admin and user clusters. You must only provide the cluster name and its related kubeconfig file, and sign in separately to each cluster.

Before you sign in, ensure you do the following:

• Download the gdcloud CLI binary and install it in your system. For more information, see Download the gdcloud CLI.
• Set up and initialize the gdcloud CLI default configuration. Make sure to set the correct organization URL, which is used to fetch the login config endpoint. For more information, see gdcloud CLI installation.
• Install the authentication plugin gdcloud-k8s-auth-plugin. For more information, see gdcloud CLI authentication.

Important: Run the next steps on your system with your user account and not with the root account. The gdcloud CLI doesn't automatically open a browser while in root mode.

To sign in to an org admin or user cluster, complete the following steps:

• Org admin cluster:

1. Export the path on where you want to store the org admin kubeconfig file:

   export KUBECONFIG=PATH_TO_STORE_KUBECONFIG
   

   Replace PATH_TO_STORE_KUBECONFIG with the path to the directory of where to store the kubeconfig file.

2. Authenticate your gdcloud CLI instance to sign in. There are two ways to authenticate:

   • Standard browser login: Use this authentication flow when logging in from a browser.

     gdcloud auth login
     

   • Secondary device login: Use this authentication flow if your primary device does not have a browser available. This flow starts the login on the primary device with no browser access and continues the login with the secondary device that has browser access.

     1. Initiate the login on your primary device with no browser:

        gdcloud auth login --no-browser
        

        The command in the primary device prints another gdcloud command that you must run on the secondary device in step c.

     2. Repeat step 1 to download the certificate on the secondary device.

     3. Complete the login on the secondary device by entering the command printed on the primary device in step a.

   This action opens a browser to sign in to the configured identity provider (IdP). Provide the user and password that you set during the initial gdcloud CLI setup to sign in.

   Note: If you see an error x509: certificate signed by unknown authority, your workstation does not trust the CA certificate used in GDC. Follow your organization's procedure to check the trusted certification store for your workstation.
   Warning: Using --login-config-cert with an unverified certificate makes you vulnerable to man-in-the-middle attacks. Ensure that you rely only on your workstation's trust store instead of trusting a CA certificate from unknown sources.

• User cluster:

1. Authenticate your gdcloud CLI instance to sign in. There are two ways to authenticate:

   • Standard browser login: Use this authentication flow when logging in from a browser.

     gdcloud auth login
     

   • Secondary device login: Use this authentication flow if your primary device does not have a browser available. This flow starts the login on the primary device with no browser access and continues the login with the secondary device that has browser access.

     1. Initiate the login on your primary device with no browser:

        gdcloud auth login --no-browser
        

        The command in the primary device prints another gdcloud command that you must run on the secondary device in step c.

     2. Repeat step 1 to download the certificate on the secondary device.

     3. Complete the login on the secondary device by entering the command printed on the primary device in step a.

   This action opens a browser to sign in to the configured identity provider (IdP). Provide the user and password that you set during the initial gdcloud CLI setup to sign in.

   Warning: Using --login-config-cert with an unverified certificate makes you vulnerable to man-in-the-middle attacks. Ensure that you rely only on your workstation's trust store instead of trusting a CA certificate from unknown sources.

2. Export your user identity kubeconfig file as a variable:

   export KUBECONFIG=/tmp/admin-kubeconfig-with-user-identity.yaml
   

3. Generate a kubeconfig file with your user identity:

   gdcloud clusters get-credentials CLUSTER_NAME
   

   Note: The list of available cluster names is available in the login config URL:
   https://GDC_URL/.well-known/login-config.

   A kubeconfig file is generated with your user identity. The following YAML file shows an example:

   apiVersion: v1
   clusters:
   - cluster:
     certificate-authority-data: <REDACTED>
     server: https://10.200.0.32:443
   name: cluster-name
   contexts:
   - context:
     cluster: cluster-name
     user: cluster-name-anthos-default-user
   name: cluster-name-cluster-name-anthos-default-user
   current-context: cluster-name-cluster-name-anthos-default-user
   kind: Config
   preferences: {}
   users:
   - name: cluster-name-anthos-default-user
   user:
     exec:
       apiVersion: client.authentication.k8s.io/v1
       args:
       - --audience=root-admin
       command: gdcloud-k8s-auth-plugin
       env: null
       installHint: Run 'gdcloud components install gdcloud-k8s-auth-plugin' to use plugin
       interactiveMode: Never
       provideClusterInfo: false
   

4. To verify that you can access the cluster, sign in with the generated kubeconfig file with a user identity:

   kubectl --kubeconfig /tmp/admin-kubeconfig-with-user-identity.yaml version
   

Sign out

To sign out of the GDC console, do the following:

Console

Click Logout in the menu bar.

CLI

Log out from the CLI:

gdcloud auth revoke

Note: Any page that relies on Kubernetes resources doesn't currently work. Chrome debug console shows "forbidden" errors in responses. This error occurs because the user has no permissions granted and is not bound to any roles. See Grant access to resources for instructions to grant permissions.

Session inactivity logout

After fifteen or more minutes of inactivity in a session, the GDC console and gdcloud CLI logs you out. Distributed Cloud considers session inactivity as a period during an open session with no active engagement from you, such as no cursor or keyboard movement. An active session lasts up to twelve hours with user activity.

Console

For session inactivity, the GDC console logs you out. Two minutes before the GDC console logs you out for inactivity, you receive a dialog that cautions you of the logout:

After logging you out for inactivity, you see the following screen:

To log back in to the GDC console, select your identity provider and add your login credentials. If you use a service, such as the monitoring dashboard, and the GDC console logs you out for inactivity, log back in to gain access.

gdcloud

For session inactivity, the gdcloud CLI logs you out. After the gdcloud CLI logs you out, and you attempt to run a command, you receive an authorization error:

Error: error when creating kube client: unable to create k8sclient: Unauthorized

To log back in to GDC, follow the CLI steps in Sign in.

If you log back in to GDC through an org admin cluster, your kubeconfig file automatically updates. To avoid your kubeconfig file updating, use the --skip-kubeconfig-update flag in the gdcloud auth login command.

Note: Commands that don't make API requests, such as gdcloud init and gdcloud config, are not counted towards your activity. When using these commands, the gdcloud CLI logs you out regardless.

kubectl

The gdcloud CLI expires your kubeconfig files after session inactivity. If you attempt to run a kubectl command after inactivity, you receive an authorization error:

error: You must be logged in to the server (Unauthorized)

To log back in and use your kubeconfig file, follow the CLI steps in Sign in. For every session timeout, you must regenerate your kubeconfig files.

Monitor sign in and new user activities

Activities such as signing in are exported as audit logs. For more information about viewing audit logs, see Audit logs.
