Chapter 9. IPv6 and dual-stack deployments Your standalone Red Hat Quay deployment can now be served in locations that only support IPv6, such as Telco and Edge environments. Support is also offered for dual-stack networking so your Red Hat Quay deployment can listen on IPv4 and IPv6 simultaneously. For a list of known limitations, see IPv6 limitations 9.1. Enabling the IPv6 protocol family Use the following procedure to enable IPv6 support on your standalone Red Hat Quay deployment. Prerequisites You have updated Red Hat Quay to 3.8. Your host and container software platform (Docker, Podman) must be configured to support IPv6. Procedure In your deployment's config.yaml file, add the FEATURE_LISTEN_IP_VERSION parameter and set it to IPv6 , for example: --- FEATURE_GOOGLE_LOGIN: false FEATURE_INVITE_ONLY_USER_CREATION: false FEATURE_LISTEN_IP_VERSION: IPv6 FEATURE_MAILING: false FEATURE_NONSUPERUSER_TEAM_SYNCING_SETUP: false --- Start, or restart, your Red Hat Quay deployment. Check that your deployment is listening to IPv6 by entering the following command: USD curl <quay_endpoint>/health/instance {"data":{"services":{"auth":true,"database":true,"disk_space":true,"registry_gunicorn":true,"service_key":true,"web_gunicorn":true}},"status_code":200} After enabling IPv6 in your deployment's config.yaml , all Red Hat Quay features can be used as normal, so long as your environment is configured to use IPv6 and is not hindered by the ipv6-limitations[current limitations]. Warning If your environment is configured to IPv4, but the FEATURE_LISTEN_IP_VERSION configuration field is set to IPv6 , Red Hat Quay will fail to deploy. 9.2. Enabling the dual-stack protocol family Use the following procedure to enable dual-stack (IPv4 and IPv6) support on your standalone Red Hat Quay deployment. Prerequisites You have updated Red Hat Quay to 3.8. Your host and container software platform (Docker, Podman) must be configured to support IPv6. Procedure In your deployment's config.yaml file, add the FEATURE_LISTEN_IP_VERSION parameter and set it to dual-stack , for example: --- FEATURE_GOOGLE_LOGIN: false FEATURE_INVITE_ONLY_USER_CREATION: false FEATURE_LISTEN_IP_VERSION: dual-stack FEATURE_MAILING: false FEATURE_NONSUPERUSER_TEAM_SYNCING_SETUP: false --- Start, or restart, your Red Hat Quay deployment. Check that your deployment is listening to both channels by entering the following command: For IPv4, enter the following command: USD curl --ipv4 <quay_endpoint> {"data":{"services":{"auth":true,"database":true,"disk_space":true,"registry_gunicorn":true,"service_key":true,"web_gunicorn":true}},"status_code":200} For IPv6, enter the following command: USD curl --ipv6 <quay_endpoint> {"data":{"services":{"auth":true,"database":true,"disk_space":true,"registry_gunicorn":true,"service_key":true,"web_gunicorn":true}},"status_code":200} After enabling dual-stack in your deployment's config.yaml , all Red Hat Quay features can be used as normal, so long as your environment is configured for dual-stack. 9.3. IPv6 and dua-stack limitations Currently, attempting to configure your Red Hat Quay deployment with the common Azure Blob Storage configuration will not work on IPv6 single stack environments. Because the endpoint of Azure Blob Storage does not support IPv6, there is no workaround in place for this issue. For more information, see PROJQUAY-4433 . Currently, attempting to configure your Red Hat Quay deployment with Amazon S3 CloudFront will not work on IPv6 single stack environments. Because the endpoint of Amazon S3 CloudFront does not support IPv6, there is no workaround in place for this issue. For more information, see PROJQUAY-4470 .
