Error: Default network exists in a project Bridgecrew Policy ID: BC_GCP_NETWORKING_7 The default network has a pre-configured network configuration and automatically generates the following insecure firewall rules: These automatically created firewall rules do not get audit logged and cannot be configured to enable firewall rule logging. In addition, the default network is an auto mode network, which means that its subnets use the same predefined range of IP addresses. As a
result, it is not possible to use Cloud VPN or VPC Network Peering with the default network. We recommend that a project should not have a default network to prevent use of default network. Based on organization security and networking requirements, the organization should create a new network and delete the default network. To change the policy using the GCP Console, follow these steps: For each Google Cloud
Platform project: Updated 3 days ago Configuring authorization for Google Cloud PlatformRoles Configuring GCP for OpenShift Container Platform requires the following GCP role:
You can also create a service account to avoid using personal users when deploying GCP objects. Scopes and service accounts GCP uses scopes to determine if an authenticated identity is authorized to perform operations within a resource. For example, if application A with a read-only scope access token can only read, while application B with a read-write scope access token can read and modify data. You can specify scopes using the By default, a newly created instance is automatically enabled to run as the default service account with the following access scopes:
You can specify another service account with the Google Compute Engine objectsIntegrating OpenShift Container Platform with Google Compute Engine (GCE) requires the following components or services. A GCP project A GCP project is the base level organizing entity that forms the basis for creating, enabling, and using all GCP services. This includes managing APIs, enabling billing, adding and removing collaborators, and managing permissions.
Billing You cannot create new resources unless billing is attached to an account. The new project can be linked to an existing project or new information can be entered. Cloud identity and access management Deploying OpenShift Container Platform requires the proper permissions. A user must be able to create service accounts, cloud storage, instances, images, templates, Cloud DNS entries, and deploy load balancers and health checks. Delete permissions are also helpful in order to be able to redeploy the environment while testing. You can create service accounts with specific permissions, then use them to deploy infrastructure components instead of regular users. You can also create roles to limit access to different users or service accounts. GCP instances use service accounts to allow applications to call GCP APIs. For example, OpenShift Container Platform node hosts can call the GCP disk API to provide a persistent volume to an application. SSH keys GCP injects SSH public keys as authorized keys so you can log in using SSH in the created instances. You can configure the SSH keys per instance or per project. You can use existing SSH keys. GCP metadata can help with storing the SSH keys that are injected at boot time in the instances to allow SSH access. GCP regions and zones GCP has a global infrastructure that covers regions and availability zones. While deploying OpenShift Container Platform in GCP on different zones can help avoid single-point-of-failures, there are some caveats regarding storage. GCP disks are created within a zone. Therefore, if a OpenShift Container Platform node host goes down in zone "A" and the pods move to zone "B", the persistent storage cannot be attached to those pods because the disks are in a different zone. Deploying a single zone of multizone OpenShift Container Platform environment is an important decision to make before installing OpenShift Container Platform. If deploying a multizone environment, the recommended setup is to use three different zones in a single region. External IP address So that GCP instances can communicate with the Internet, you must attach an external IP address to the instance. Also, an external IP address is required to communicate with instances deployed in GCP from outside the Virtual Private Cloud (VPC) Network. Cloud DNS GCP cloud DNS is a DNS service used to publish domain names to the global DNS using GCP DNS servers. The public cloud DNS zone requires a domain name that you purchased either through Google’s "Domains" service or through a third-party provider. When you create the zone, you must add the name servers provided by Google to the registrar.
Load balancing The GCP load balancing service enables the distribution of traffic across multiple instances in the GCP cloud. There are five types of Load Balancing:
Instances sizes A successful OpenShift Container Platform environment requires some minimum hardware requirements: Table 1. Instances sizes
Storage Options By default, each GCP instance has a small root persistent disk that contains the operating system. When applications running on the instance require more storage space, you can add additional storage options to the instance:
Can we create virtual machines without creating virtual networks?A VNet is used to provide the VM with DHCP and Security Group services. A VM would be unable to obtain an IP address without it. In the same manner that a V1Vm could not be created without a cloud service, an Azure VM cannot be created without a vnet.
Which of the following is not a service provided by VPC network?VPC networks do not support broadcast or multicast addresses within the network. For more information about IPv6 subnet ranges, see Subnets.
Which of the following is supported by VPC networks?VPN Connection are connectivity option for VPC.
All the mentioned connections type supports certain types of VPN connections such as software VPN, AWS Managed VPN, etc.
Which statement is true about Google VPC network and subnets?Which statement is true about Google VPC networks and subnets? An application running in a Compute Engine virtual machine needs high-performance scratch space.
