For more information about allowlisting ports, see\n[Troubleshoot issues](/memorystore/docs/cluster/troubleshoot-issues#connection_error_caused_by_firewall_rules).\n\nCross region access\n-------------------\n\nYou can access a Memorystore for Redis Cluster instance from a client located in a\ndifferent region than where the Memorystore instance is located.\n\nView your cluster's discovery endpoint\n--------------------------------------\n\nTo view your Memorystore cluster's [discovery endpoint](/memorystore/docs/cluster/overview#discovery_endpoint), use the following instructions: \n\n### Console\n\n1. Go to the **Memorystore for Redis Cluster** page in the Google Cloud console.\n\n [Memorystore for Redis Cluster](https://console.cloud.google.com/memorystore/redis/clusters?)\n2. Click your Cluster ID.\n\n3. In the **Connect to this instance** section, take a note of the IP address\n and port number next to **Discovery Endpoint**. These two values used\n together are your cluster's discovery endpoint.\n\n### gcloud\n\nTo view your cluster's discovery endpoint, run the `describe`\ngcloud CLI as explained in the [view instance details](/memorystore/docs/cluster/create-manage-instances#view_instance_details) section.\n\nThe output should be similar to the following: \n\n authorizationMode: AUTH_MODE_DISABLED\n createTime: '2023-08-04T17:49:07.988918793Z'\n discoveryEndpoints:\n - address: 10.142.0.13\n port: 6379\n pscConfig:\n - network: projects/my-project-364018/global/networks/default\n name: projects/my-project-364018/locations/us-east1/clusters/my-cluster-1\n pscConnections:\n - address: 10.142.0.13\n forwardingRule: https://www.googleapis.com/compute/v1/projects/my-project-364018/regions/us-east1/forwardingRules/sca-auto-fr-5bc46f69-ec80-4c5a-8971-ce267a4d8ddd\n network: projects/my-project-364018/global/networks/default\n projectId: my-project-364018\n pscConnectionId: '25734306048376845'\n - address: 10.142.0.10\n forwardingRule: https://www.googleapis.com/compute/v1/projects/my-project-364018/regions/us-east1/.\n forwardingRules/sca-auto-fr-817b64c5-85ac-48d0-82e3-c6fa99b4e67d\n network: projects/my-project-364018/global/networks/default\n projectId: my-project-364018\n pscConnectionId: '25734306048376842'\n replicaCount: 0\n shardCount: 3\n sizeGb: 39\n state: ACTIVE\n tier: PERFORMANCE\n transitEncryptionMode: TRANSIT_ENCRYPTION_MODE_DISABLED\n uid: cddda5de-d91f-449b-8755-3a665430271a\n\nTake a note of the endpoint address and port number listed in the\n`discovery_endpoints:` section. These two values used together are your\ncluster's discovery endpoint.\n\nConnect from a Compute Engine VM using redis-cli\n------------------------------------------------\n\nYou can connect to the Memorystore for Redis Cluster instance from any\nCompute Engine VM that uses the Memorystore instance's\nauthorized network.\n\nTo connect to the instance:\n\n1. If you don't already have a Linux Compute Engine VM that uses the\n authorized network for your Memorystore for Redis Cluster instance, create one and\n connect to it by following [Quickstart to create a Linux VM](/compute/docs/create-linux-vm-instance).\n\n2. Install `redis-cli` version 6.0 or newer on the Compute Engine VM by\n following the instructions at [Install Redis on Linux](https://redis.io/docs/getting-started/installation/install-redis-on-linux/).\n\n3. [View your cluster's discovery endpoint](/memorystore/docs/cluster/connect-cluster-instance#view_your_clusters_discovery_endpoint)\n and make a note of it.\n\n4. Connect to your instance's discovery endpoint by running the following\n command:\n\n ```\n redis-cli -h DISCOVERY_ENDPOINT_ADDRESS -p PORT_NUMBER -c\n ```\n\n Where:\n - \u003cvar translate=\"no\"\u003eDISCOVERY_ENDPOINT_ADDRESS\u003c/var\u003e and \u003cvar translate=\"no\"\u003ePORT_NUMBER\u003c/var\u003e are the values you noted in the previous step.\n\n | **Note:** The `-c` switch is used to enable the `redis-cli` cluster support mode. If the `-c` switch is not provided, when you try to access keys from a different shard than the one you are connected to, it results in a `MOVED` error. In the cluster support mode the client is automatically reconnected to the address returned in the error response. For more details, see [Using Redis-CLI with a Redis Cluster](https://developer.redis.com/operate/redis-at-scale/scalability/redis-cli-with-redis-cluster/).\n5. Run the `CLUSTER SHARDS` command to view your cluster topology. Take a note\n of one of the node's IP addresses and port numbers.\n\n6. Connect to your desired node by running the following command:\n\n ```\n redis-cli -h NODE_IP_ADDRESS -p NODE_PORT -c\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eNODE_IP_ADDRESS\u003c/var\u003e is the node's IP address you found in the previous step.\n - \u003cvar translate=\"no\"\u003eNODE_PORT\u003c/var\u003e is the node's port number you found in the previous step.\n7. Once connected to the node, enter some Redis commands:\n\n Enter: \n\n ```\n PING\n ```\n\n Result: \n\n ```\n PONG\n ```\n\n Enter \n\n ```\n SET HELLO WORLD\n ```\n\n Result: \n\n ```\n OK\n ```\n\n Enter: \n\n ```\n GET HELLO\n ```\n\n Result: \n\n ```\n \"WORLD\"\n ```\n8. Once you are done testing your connection to the Redis node, you should\n consider deleting the Compute Engine VM you used to connect to the\n Redis instance. Doing so helps you avoid incurring charges to your\n Cloud Billing account.\n\nConnect to an in-transit encryption enabled instance\n----------------------------------------------------\n\nThis section provides an example of how to connect to a Memorystore for Redis Cluster\ninstance that has in-transit encryption enabled.\n\n1. If you don't already have a Compute Engine VM that uses the same\n authorized network as the Redis instance from the previous step, create one\n and connect to it by following [Quickstart using a Linux VM](/compute/docs/create-linux-vm-instance).\n\n 1. Install `redis-cli` version 6.0 or newer on the Compute Engine VM by following the instructions at [Install Redis on Linux](https://redis.io/docs/getting-started/installation/install-redis-on-linux/).\n2. Install your instance's certificate authority on the Linux VM by following\n the instructions at [Install certificate authorities on your client](https://cloud.google.com/memorystore/docs/cluster/manage-in-transit-encryption#install_certificate_authorities_on_your_client).\n\n3. [View your cluster's discovery endpoint](/memorystore/docs/cluster/connect-cluster-instance#view_your_clusters_discovery_endpoint)\n and make a note of it.\n\n4. Connect to your instance's discovery endpoint by running the following\n command:\n\n ```\n redis-cli -h DISCOVERY_ENDPOINT_ADDRESS -p PORT_NUMBER -c --tls --cacert /tmp/server_ca.pem\n ```\n\n Where:\n - \u003cvar translate=\"no\"\u003eDISCOVERY_ENDPOINT_ADDRESS\u003c/var\u003e and \u003cvar translate=\"no\"\u003ePORT_NUMBER\u003c/var\u003e are the values you noted in the previous step.\n\n | **Note:** The `-c` switch is used to enable the `redis-cli` cluster support mode. If the `-c` switch is not provided, when you try to access keys from a different shard than the one you are connected to, it results in a `MOVED` error. In the cluster support mode the client is automatically reconnected to the address returned in the error response.
