   # chown foreman /usr/share/foreman/gce_key.json

   Copy to Clipboard Toggle word wrap

4. On Satellite Server, configure permissions for your service account key to ensure that the file is readable:

   # chmod 0600 /usr/share/foreman/gce_key.json

   Copy to Clipboard Toggle word wrap

5. On Satellite Server, restore SELinux context for your service account key:

   # restorecon -vv /usr/share/foreman/gce_key.json

3. On Satellite Server, change the owner for your service account key to the foreman user:

   # chown foreman /usr/share/foreman/gce_key.json

   Copy to Clipboard Toggle word wrap

4. On Satellite Server, configure permissions for your service account key to ensure that the file is readable:

   # chmod 0600 /usr/share/foreman/gce_key.json

   Copy to Clipboard Toggle word wrap

5. On Satellite Server, restore SELinux context for your service account key:

   # restorecon -vv /usr/share/foreman/gce_key.json

   Copy to Clipboard Toggle word wrap

6. Use the hammer compute-resource create command to add a GCE compute resource to Satellite:

   # hammer compute-resource create \
   --email "My_GCE_Email" \
   --key-path "Path_To_My_GCE_Key.json" \
   --name "My_GCE_Compute_Resource" \
   --project "My_GCE_Project_ID" \
   --provider "gce" \
   --zone "My_Zone"

Procedure

1. In the Satellite web UI, navigate to Infrastructure > Compute Resources and click the name of the Google Compute Engine connection.
2. Click Create Image.
3. In the Name field, enter a name for the image.
4. From the Operating System list, select the base operating system of the image.
5. From the Architecture list, select the operating system architecture.
6. In the Username field, enter the SSH user name for image access. Specify a user other than root, because the root user cannot connect to a GCE instance using SSH keys. The username must begin with a letter and consist of lowercase letters and numbers.
7. From the Image list, select an image from the Google Compute Engine compute resource.
8. Optional: Select the User Data checkbox if the image supports user data input, such as cloud-init data.
9. Click Submit to save the image details.

Procedure

1. In the Satellite web UI, navigate to Infrastructure > Compute Profiles.
2. In the Compute Profiles window, click the name of an existing compute profile, or click Create Compute Profile, enter a Name, and click Submit.
3. Click the name of the GCE compute resource.
4. From the Machine Type list, select the machine type to use for provisioning.
5. From the Image list, select the image to use for provisioning.
6. From the Network list, select the Google GCE network to use for provisioning.
7. Optional: Select the Associate Ephemeral External IP checkbox to assign a dynamic ephemeral IP address that Satellite uses to communicate with the host. This public IP address changes when you reboot the host. If you need a permanent IP address, reserve a static public IP address on Google GCE and attach it to the host.
8. In the Size (GB) field, enter the size of the storage to create on the host.
9. Click Submit to save the compute profile.

CLI procedure

1. Create a compute profile to use with the Google GCE compute resource:

   # hammer compute-profile create --name My_GCE_Compute_Profile

   Copy to Clipboard Toggle word wrap

2. Add GCE details to the compute profile:

   # hammer compute-profile values create \
   --compute-attributes "machine_type=f1-micro,associate_external_ip=true,network=default" \
   --compute-profile "My_GCE_Compute_Profile" \
   --compute-resource "My_GCE_Compute_Resource" \
   --volume "size_gb=20"

   Copy to Clipboard Toggle word wrap

Procedure

1. In the Satellite web UI, navigate to Hosts > Create Host.
2. In the Name field, enter a name for the host.
3. Click the Organization and Location tabs to ensure that the provisioning context is automatically set to the current context.
4. From the Host Group list, select the host group that you want to use to populate the form.
5. From the Deploy on list, select the Google Compute Engine connection.
6. From the Compute Profile list, select a profile to use to automatically populate virtual machine settings.
7. From the Lifecycle Environment list, select the environment.
8. Click the Interfaces tab and click Edit on the host’s interface.

9. Verify that the fields are automatically populated, particularly the following items:

   • The Name from the Host tab becomes the DNS name.
   • The MAC address field is blank. Google Compute Engine assigns a MAC address to the host during provisioning.
   • Satellite Server automatically assigns an IP address for the new host.
   • The Domain field is populated with the required domain.
   • The Managed, Primary, and Provision options are automatically selected for the first interface on the host. If not, select them.
10. Click the Operating System tab, and confirm that all fields automatically contain values.
11. Click Resolve in Provisioning templates to check the new host can identify the right provisioning templates to use.
12. Click the Virtual Machine tab and confirm that these settings are populated with details from the host group and compute profile. Modify these settings to suit your needs.
13. Click the Parameters tab, and ensure that a parameter exists that provides an activation key. If not, add an activation key.
14. Click Submit to save the host entry.

Procedure

1. In the Satellite web UI, navigate to Infrastructure > Compute Resources.
2. Select your Google GCE provider.
3. On the Virtual Machines tab, click Delete from the Actions menu. This deletes the virtual machine from the Google GCE compute resource while retaining any associated hosts within Satellite. If you want to delete the orphaned host, navigate to Hosts > All Hosts and delete the host manually.

Procedure

1. Uninstall the GCE compute resource provider from your Satellite Server:

   # yum remove -y foreman-gce
   # satellite-installer --no-enable-foreman-compute-gce

   Copy to Clipboard Toggle word wrap
2. Optional: In the Satellite web UI, navigate to Administer > About and select the Available Providers tab to verify the removal of the Google GCE plugin.
