Any network on which you provision a Memorystore for Memcached instance must\nhave a private services access connection. Otherwise, you cannot select that\nnetwork when creating a Memorystore for Memcached instance. See [Networking](/memorystore/docs/memcached/networking)\nfor more details.\n\nWe recommend that your organization's networking team / networking admin manage\nthese steps for setting up a private services access connection before allowing\napplication developers to provision Memcached instances.\n\nIf you are an application developer, usually your networking team should manage\nestablishing a private services access connection. For more details, see [Communicating networking requirements](/memorystore/docs/memcached/networking#communicating_networking_requirements).\n\nThere are three ways to set up a private services access connection.\n\n1. **Gcloud** (Recommended)\n\n - Establishes a private services access connection before the Memcached instance creation process.\n2. **Console: VPC network**\n\n - Establishes the connection before the Memcached instance creation process.\n3. **Console: Memcached**\n\n - Establishes the connection during the Memcached instance creation process.\n\n### gcloud\n\n1. Enable the Service Networking API:\n\n [Enable the Service Networking API](https://console.cloud.google.com/apis/library/servicenetworking.googleapis.com)\n\n2. [Check to see](/memorystore/docs/memcached/verifying-connection) if\n a private service access connection has been established for your network.\n\n - If the connection has already been established, see [Creating Memcached instances](/memorystore/docs/memcached/creating-managing-instances#creating_memcached_instances) for instructions on how to create a Memcached instance.\n3. Open a terminal window.\n\n4. Set your default project by running the following command, replacing\n \u003cvar translate=\"no\"\u003evariables\u003c/var\u003e with appropriate values:\n\n ```\n gcloud config set core/project project-id\n ```\n5. Reserve an IP address range in your network by running the following command:\n\n ```\n gcloud compute addresses create reserved-range-name --global --prefix-length=24 --description=description --network=vpc-network --purpose=vpc_peering\n ```\n - Memorystore chooses a CIDR range for you automatically so you\n don't have to specify it. However, you can set the CIDR prefix length.\n For this example, the length is set to `24`. This value must be at\n least `24`, but you can set it to any smaller prefix length, such as\n `23`. This creates a larger IP address range.\n\n - For information on managing private services access, see [Configuring private services access](/vpc/docs/configure-private-services-access).\n\n6. Create a [private connection](/vpc/docs/configure-private-services-access#creating-connection)\n between your network and the private services access network by running the\n following command:\n\n ```\n gcloud services vpc-peerings connect --service=servicenetworking.googleapis.com --ranges=reserved-range-name --network=vpc-network --project=project-id\n ```\n\n### Console: VPC network\n\n1. Enable the Service Networking API:\n\n [Enable the Service Networking API](https://console.cloud.google.com/apis/library/servicenetworking.googleapis.com)\n\n2. [Check to see](/memorystore/docs/memcached/verifying-connection) if\n a private service access connection has been established for your network.\n\n - If the connection has already been established, see [Creating Memcached instances](/memorystore/docs/memcached/creating-managing-instances#creating_memcached_instances) for instructions on how to create a Memcached instance.\n3. Go to the VPC Networks page in the Google Cloud console.\n\n [Go to the VPC networks page](https://console.cloud.google.com/networking/networks/list?) \n\n4. Click the name of your network. Usually it is named \"default\".\n\n5. Click **Private service connection**.\n\n6. Click **Allocate IP ranges for services**.\n\n7. Click **Allocate IP range**.\n\n - Enter a name for your range, such as \"private-services-access-range\".\n - Enter a description for your range, such as \"Range of IP addresses to be used for the Private services access connection\".\n - Select **Automatic** if you want Google to choose your range for you.\n 1. Enter a CIDR prefix of `/24` or less. For example, `/23` is an acceptable prefix.\n - Select **Custom** if you want to choose the range yourself.\n 1. Enter your desired range with a CIDR prefix of `/24` or less.\n - Click **Allocate**.\n8. Click **Private connections to services**.\n\n9. Click the **Create connection** button.\n\n10. Under the **Assigned allocation** dropdown, select the range you just\n created in the steps above.\n\n11. Click **Ok**.\n\n12. Click **Connect**.\n\n13. Refresh the page to see your new connection listed under the **Private\n connections to services** tab.\n\n### Console: Memcached\n\n1. Enable the Service Networking API:\n\n [Enable the Service Networking API](https://console.cloud.google.com/apis/library/servicenetworking.googleapis.com)\n\n2. [Check to see](/memorystore/docs/memcached/verifying-connection) if\n a private service access connection has been established for your network.\n\n - If the connection has already been established, see [Creating Memcached instances](/memorystore/docs/memcached/creating-managing-instances#creating_memcached_instances) for instructions on how to create a Memcached instance.\n3. Follow the steps at [Creating Memcached instances](/memorystore/docs/memcached/creating-managing-instances#creating_memcached_instances)\n until you see a panel that says, **Private service connection required**.\n\n | **Note:** you do not need to complete the instance creation steps in order to establish a private services access connection. You can establish the connection for your network, and abandon the instance creation process, if you wish.\n4. Click the **Set Up Connection** button in the **Private service\n connection** panel. Doing so opens a slide out panel for setting up\n private services access.\n\n5. Enable the Service Networking API.\n\n6. Allocate an IP range using one of the following methods:\n\n - Select an existing IP range.\n - Allocate a new IP range.\n - Enter a **name** for your range.\n - Enter a valid CIDR range with a block size of `/24`. For example: `10.0.0.0/24`.\n - Use an automatically allocated IP range.\n7. Click the **Create Connection** button.\n\nWhat's next\n-----------\n\n- [Create a Memcached instance](/memorystore/docs/memcached/creating-managing-instances).\n- [Connect to a Memcached instance](/memorystore/docs/memcached/connecting-memcached-instance)."]]
