Chapter 7. Creating secure HTTP load balancers In Red Hat OpenStack Services on OpenShift (RHOSO) environments, you can create various types of load balancers to manage secure HTTP (HTTPS) network traffic: Section 7.1, "About non-terminated HTTPS load balancers" Section 7.2, "Creating a non-terminated HTTPS load balancer" Section 7.3, "About TLS-terminated HTTPS load balancers" Section 7.4, "Creating a TLS-terminated HTTPS load balancer" Section 7.5, "Creating a TLS-terminated HTTPS load balancer with SNI" Section 7.6, "Creating a TLS-terminated load balancer with an HTTP/2 listener" Section 7.7, "Creating HTTP and TLS-terminated HTTPS load balancing on the same IP and back-end" 7.1. About non-terminated HTTPS load balancers A non-terminated HTTPS load balancer acts effectively like a generic TCP load balancer: the load balancer forwards the raw TCP traffic from the web client to the back-end servers where the HTTPS connection is terminated with the web clients. While non-terminated HTTPS load balancers do not support advanced load balancer features like Layer 7 functionality, they do lower load balancer resource utilization by managing the certificates and keys themselves. 7.2. Creating a non-terminated HTTPS load balancer If your application requires HTTPS traffic to terminate on the back-end member servers, typically called HTTPS pass through , you can use the HTTPS protocol for your Red Hat OpenStack Services on OpenShift (RHOSO) load balancer listeners in a RHOSO environment. Prerequisites The administrator has created a project for you and has provided you with a clouds.yaml file for you to access the cloud. The python-openstackclient package resides on your workstation. A shared external (public) subnet that you can reach from the internet. Procedure Confirm that the system OS_CLOUD variable is set for your cloud: USD echo USDOS_CLOUD my_cloud Reset the variable if necessary: USD export OS_CLOUD=my_other_cloud As an alternative, you can specify the cloud name by adding the --os-cloud <cloud_name> option each time you run an openstack command. Create a load balancer ( lb1 ) on a public subnet ( public_subnet ). Note Values inside parentheses are sample values that are used in the example commands in this procedure. Substitute these sample values with values that are appropriate for your site. Example Create a listener ( listener1 ) on a port ( 443 ). Example Create the listener default pool ( pool1 ). Example The command in this example creates an HTTPS pool that uses a private subnet containing back-end servers that host HTTPS applications configured with a TLS-encrypted web application on TCP port 443: Create a health monitor ( healthmon1 ) on the pool ( pool1 ) of type ( TLS-HELLO ) that connects to the back-end servers and tests the path ( / ). Health checks are recommended but not required. If no health monitor is defined, the member server is assumed to be ONLINE . Example Add load balancer members ( 192.0.2.10 and 192.0.2.11 ) on the private subnet ( private_subnet ) to the default pool. Example In this example, the back-end servers, 192.0.2.10 and 192.0.2.11 , are named member1 and member2 , respectively: Verification View and verify the load balancer ( lb1 ) settings. Example Sample output When a health monitor is present and functioning properly, you can check the status of each member. Example A working member ( member1 ) has an ONLINE value for its operating_status . Sample output 7.3. About TLS-terminated HTTPS load balancers When a TLS-terminated HTTPS load balancer is implemented in a Red Hat OpenStack Services on OpenShift (RHOSO) environment, web clients communicate with the load balancer over Transport Layer Security (TLS) protocols. The load balancer terminates the TLS session and forwards the decrypted requests to the back-end servers. When you terminate the TLS session on the load balancer, you offload the CPU-intensive encryption operations to the load balancer, and allow the load balancer to use advanced features such as Layer 7 inspection. 7.4. Creating a TLS-terminated HTTPS load balancer When you use TLS-terminated HTTPS load balancers, you offload the CPU-intensive encryption operations to the load balancer, and allow the load balancer to use advanced features such as Layer 7 inspection. In Red Hat OpenStack Services on OpenShift (RHOSO) environments, it is a best practice to also create a health monitor to ensure that your back-end members remain available. Prerequisites The administrator has created a project for you and has provided you with a clouds.yaml file for you to access the cloud. The python-openstackclient package resides on your workstation. A shared external (public) subnet that you can reach from the internet. TLS public-key cryptography is configured with the following characteristics: A TLS certificate, key, and intermediate certificate chain is obtained from an external certificate authority (CA) for the DNS name that is assigned to the load balancer VIP address, for example, www.example.com . The certificate, key, and intermediate certificate chain reside in separate files in the current directory. The key and certificate are PEM-encoded. The intermediate certificate chain contains multiple certificates that are PEM-encoded and concatenated together. You must configure the Load-balancing service (octavia) to use the Key Manager service (barbican). For more information, see the Managing secrets with the Key Manager service guide. Procedure Combine the key ( server.key ), certificate ( server.crt ), and intermediate certificate chain ( ca-chain.crt ) into a single PKCS12 file ( server.p12 ). Note Values inside parentheses are sample values that are used in the example commands in this procedure. Substitute these sample values with values that are appropriate for your site. Example Note The following procedure does not work if you password protect the PKCS12 file. Confirm that the system OS_CLOUD variable is set for your cloud: USD echo USDOS_CLOUD my_cloud Reset the variable if necessary: USD export OS_CLOUD=my_other_cloud As an alternative, you can specify the cloud name by adding the --os-cloud <cloud_name> option each time you run an openstack command. Use the Key Manager service to create a secret resource ( tls_secret1 ) for the PKCS12 file. Example Create a load balancer ( lb1 ) on the public subnet ( public_subnet ). Example Create a TERMINATED_HTTPS listener ( listener1 ), and reference the secret resource as the default TLS container for the listener. Example Create a pool ( pool1 ) and make it the default pool for the listener. Example The command in this example creates an HTTP pool that uses a private subnet containing back-end servers that host non-secure HTTP applications on TCP port 80: Create a health monitor ( healthmon1 ) of type ( HTTP ) on the pool ( pool1 ) that connects to the back-end servers and tests the path ( / ). Health checks are recommended but not required. If no health monitor is defined, the member server is assumed to be ONLINE . Example Add the non-secure HTTP back-end servers ( 192.0.2.10 and 192.0.2.11 ) on the private subnet ( private_subnet ) to the pool. Example In this example, the back-end servers, 192.0.2.10 and 192.0.2.11 , are named member1 and member2 , respectively: Verification View and verify the load balancer ( lb1 ) settings. Example Sample output When a health monitor is present and functioning properly, you can check the status of each member. Example A working member ( member1 ) has an ONLINE value for its operating_status : Sample output 7.5. Creating a TLS-terminated HTTPS load balancer with SNI For TLS-terminated HTTPS load balancers that employ Server Name Indication (SNI) technology, a single listener can contain multiple TLS certificates and enable the load balancer to know which certificate to present when it uses a shared IP. In Red Hat OpenStack Services on OpenShift (RHOSO) environments, it is a best practice to also create a health monitor to ensure that your back-end members remain available. Prerequisites The administrator has created a project for you and has provided you with a clouds.yaml file for you to access the cloud. The python-openstackclient package resides on your workstation. A shared external (public) subnet that you can reach from the internet. TLS public-key cryptography is configured with the following characteristics: Multiple TLS certificates, keys, and intermediate certificate chains have been obtained from an external certificate authority (CA) for the DNS names assigned to the load balancer VIP address, for example, www.example.com and www2.example.com . The keys and certificates are PEM-encoded. You must configure the Load-balancing service (octavia) to use the Key Manager service (barbican). For more information, see the Managing secrets with the Key Manager service guide. Procedure For each of the TLS certificates in the SNI list, combine the key ( server.key ), certificate ( server.crt ), and intermediate certificate chain ( ca-chain.crt ) into a single PKCS12 file ( server.p12 ). In this example, you create two PKCS12 files ( server.p12 and server2.p12 ) one for each certificate ( www.example.com and www2.example.com ). Note Values inside parentheses are sample values that are used in the example commands in this procedure. Substitute these sample values with values that are appropriate for your site. Example Confirm that the system OS_CLOUD variable is set for your cloud: USD echo USDOS_CLOUD my_cloud Reset the variable if necessary: USD export OS_CLOUD=my_other_cloud As an alternative, you can specify the cloud name by adding the --os-cloud <cloud_name> option each time you run an openstack command. Use the Key Manager service to create secret resources ( tls_secret1 and tls_secret2 ) for the PKCS12 file. Example Create a load balancer ( lb1 ) on the public subnet ( public_subnet ). Example Create a TERMINATED_HTTPS listener ( listener1 ), and use SNI to reference both the secret resources. (Reference tls_secret1 as the default TLS container for the listener.) Example Create a pool ( pool1 ) and make it the default pool for the listener. Example The command in this example creates an HTTP pool that uses a private subnet containing back-end servers that host non-secure HTTP applications on TCP port 80: Create a health monitor ( healthmon1 ) of type ( HTTP ) on the pool ( pool1 ) that connects to the back-end servers and tests the path ( / ). Health checks are recommended but not required. If no health monitor is defined, the member server is assumed to be ONLINE . Example Add the non-secure HTTP back-end servers ( 192.0.2.10 and 192.0.2.11 ) on the private subnet ( private_subnet ) to the pool. Example In this example, the back-end servers, 192.0.2.10 and 192.0.2.11 , are named member1 and member2 , respectively: Verification View and verify the load balancer ( lb1 ) settings. Example Sample output When a health monitor is present and functioning properly, you can check the status of each member. Example Sample output A working member ( member1 ) has an ONLINE value for its operating_status : 7.6. Creating a TLS-terminated load balancer with an HTTP/2 listener When you use TLS-terminated HTTPS load balancers, you offload the CPU-intensive encryption operations to the load balancer, and allow the load balancer to use advanced features such as Layer 7 inspection. With the addition of an HTTP/2 listener, you can leverage the HTTP/2 protocol to improve performance by loading pages faster. Load balancers negotiate HTTP/2 with clients by using the Application-Layer Protocol Negotiation (ALPN) TLS extension. The Load-balancing service (octavia) supports end-to-end HTTP/2 traffic, which means that the HTTP2 traffic is not translated by HAProxy from the point where the request reaches the listener until the response returns from the load balancer. To achieve end-to-end HTTP/2 traffic, you must have an HTTP pool with back-end re-encryption: pool members that are listening on a secure port and web applications that are configured for HTTPS traffic. You can send HTTP/2 traffic to an HTTP pool without back-end re-encryption. In this situation, HAProxy translates the traffic before it reaches the pool, and the response is translated back to HTTP/2 before it returns from the load balancer. Red Hat recommends that you create a health monitor to ensure that your back-end members remain available in your Red Hat OpenStack Services on OpenShift (RHOSO) environment. Note Currently, the Load-balancing service does not support health monitoring for TLS-terminated load balancers that use HTTP/2 listeners. Prerequisites The administrator has created a project for you and has provided you with a clouds.yaml file for you to access the cloud. The python-openstackclient package resides on your workstation. TLS public-key cryptography is configured with the following characteristics: A TLS certificate, key, and intermediate certificate chain is obtained from an external certificate authority (CA) for the DNS name that is assigned to the load balancer VIP address, for example, www.example.com . The certificate, key, and intermediate certificate chain reside in separate files in the current directory. The key and certificate are PEM-encoded. The intermediate certificate chain contains multiple certificates that are PEM-encoded and concatenated together. You must configure the Load-balancing service (octavia) to use the Key Manager service (barbican). For more information, see the Managing secrets with the Key Manager service guide. Procedure Combine the key ( server.key ), certificate ( server.crt ), and intermediate certificate chain ( ca-chain.crt ) into a single PKCS12 file ( server.p12 ). Note Values inside parentheses are sample values that are used in the example commands in this procedure. Substitute these sample values with values that are appropriate for your site. Important When you create the PKCS12 file, do not password protect the file. Example In this example, the PKCS12 file is created without a password: Use the Key Manager service to create a secret resource ( tls_secret1 ) for the PKCS12 file. Example Confirm that the system OS_CLOUD variable is set for your cloud: USD echo USDOS_CLOUD my_cloud Reset the variable if necessary: USD export OS_CLOUD=my_other_cloud As an alternative, you can specify the cloud name by adding the --os-cloud <cloud_name> option each time you run an openstack command. Create a load balancer ( lb1 ) on the public subnet ( public_subnet ). Example Create a TERMINATED_HTTPS listener ( listener1 ) and do the following: reference the secret resource ( tls_secret1 ) as the default TLS container for the listener. set the ALPN protocol ( h2 ). set the fallback protocol if the client does not support HTTP/2 ( http/1.1 ). Example Create a pool ( pool1 ) and make it the default pool for the listener. Example The command in this example creates an HTTP pool containing back-end servers that host HTTP applications configured with a web application on TCP port 80: Create a health monitor ( healthmon1 ) of type ( TCP ) on the pool ( pool1 ) that connects to the back-end servers. Health checks are recommended but not required. If no health monitor is defined, the member server is assumed to be ONLINE . Example Add the HTTP back-end servers ( 192.0.2.10 and 192.0.2.11 ) on the private subnet ( private_subnet ) to the pool. Example In this example, the back-end servers, 192.0.2.10 and 192.0.2.11 , are named member1 and member2 , respectively: Verification View and verify the load balancer ( lb1 ) settings. Example Sample output When a health monitor is present and functioning properly, you can check the status of each member. Example Sample output A working member ( member1 ) has an ONLINE value for its operating_status : 7.7. Creating HTTP and TLS-terminated HTTPS load balancing on the same IP and back-end You can configure a non-secure listener and a TLS-terminated HTTPS listener on the same load balancer and the same IP address when you want to respond to web clients with the exact same content, regardless if the client is connected with a secure or non-secure HTTP protocol. In Red Hat OpenStack Services on OpenShift (RHOSO) environments, it is a best practice to also create a health monitor to ensure that your back-end members remain available. Prerequisites The administrator has created a project for you and has provided you with a clouds.yaml file for you to access the cloud. The python-openstackclient package resides on your workstation. A shared external (public) subnet that you can reach from the internet. TLS public-key cryptography is configured with the following characteristics: A TLS certificate, key, and optional intermediate certificate chain have been obtained from an external certificate authority (CA) for the DNS name assigned to the load balancer VIP address (for example, www.example.com). The certificate, key, and intermediate certificate chain reside in separate files in the current directory. The key and certificate are PEM-encoded. The intermediate certificate chain contains multiple certificates that are PEM-encoded and concatenated together. You have configured the Load-balancing service (octavia) to use the Key Manager service (barbican). For more information, see the Managing secrets with the Key Manager service guide. The non-secure HTTP listener is configured with the same pool as the HTTPS TLS-terminated load balancer. Procedure Combine the key ( server.key ), certificate ( server.crt ), and intermediate certificate chain ( ca-chain.crt ) into a single PKCS12 file ( server.p12 ). Note Values inside parentheses are sample values that are used in the example commands in this procedure. Substitute these sample values with values that are appropriate for your site. Example Confirm that the system OS_CLOUD variable is set for your cloud: USD echo USDOS_CLOUD my_cloud Reset the variable if necessary: USD export OS_CLOUD=my_other_cloud As an alternative, you can specify the cloud name by adding the --os-cloud <cloud_name> option each time you run an openstack command. Use the Key Manager service to create a secret resource ( tls_secret1 ) for the PKCS12 file. Example Create a load balancer ( lb1 ) on the public subnet ( public_subnet ). Example Create a TERMINATED_HTTPS listener ( listener1 ), and reference the secret resource as the default TLS container for the listener. Example Create a pool ( pool1 ) and make it the default pool for the listener.

Example Add the non-secure HTTP back-end servers ( 192.0.2.10 and 192.0.2.11 ) on the private subnet ( private_subnet ) to the pool. Example In this example, the back-end servers, 192.0.2.10 and 192.0.2.11 , are named member1 and member2 , respectively: Create a non-secure, HTTP listener ( listener2 ), and make its default pool, the same as the secure listener. Example Verification View and verify the load balancer ( lb1 ) settings. Example Sample output When a health monitor is present and functioning properly, you can check the status of each member. Example Sample output A working member ( member1 ) has an ONLINE value for its operating_status :
