+ Parse ``json`` output from the upstream echo servers.
+
+This example demonstrates an Envoy proxy that listens on three ``TLS`` domains
+on the same ``IP`` address.
+
+The first two domains (``domain1`` and ``domain2``) terminate the ``TLS`` and proxy
+to upstream ``HTTP`` hosts.
+
+The other domain (``domain3``) is proxied unterminated, based on the ``SNI`` headers.
+
+It also demonstrates Envoy acting as a client proxy connecting to upstream ``SNI`` services.
+
+.. _install_sandboxes_tls_sni_step1:
+
+Step 1: Create keypairs for each of the domain endpoints
+********************************************************
+
+Change directory to ``examples/tls-sni`` in the Envoy repository.
+
+The example creates two Envoy ``TLS`` endpoints and they will require their own
+keypairs.
+
+Create self-signed certificates for these endpoints as follows:
+
+.. code-block:: console
+
+ $ pwd
+ envoy/examples/tls-sni
+
+ $ mkdir -p certs
+
+ $ openssl req -new -newkey rsa:2048 -days 365 -nodes -x509 \
+ -subj "/C=US/ST=CA/O=MyExample, Inc./CN=domain1.example.com" \
+ -keyout certs/domain1.key.pem \
+ -out certs/domain1.crt.pem

+
+.. warning::
+
+ ``SNI`` does *not* validate that the certificates presented are correct for the domain, or that they
+ were issued by a recognised certificate authority.
+
+ See the :ref:`Securing Envoy quick start guide <start_quick_start_securing>` for more information about
+ :ref:`validating cerfificates <start_quick_start_securing_validation>`.
+
+.. _install_sandboxes_tls_sni_step2:
+
+Step 2: Start the containers
+****************************
+
+Build and start the containers.
+
+This starts two upstream ``HTTP`` containers listening on the internal Docker network on port ``80``, and
+an upstream ``HTTPS`` service listening on internal port ``443``
+
+In front of these is an Envoy proxy that listens on https://localhost:10000 and serves three ``SNI`` routed
+``TLS`` domains:
+
+- ``domain1.example.com``
+- ``domain2.example.com``
+- ``domain3.example.com``
+
+The first two domains use the keys and certificates :ref:`you created in step 1 <install_sandboxes_tls_sni_step1>` to terminate ``TLS`` and
+proxy to the two upstream ``HTTP`` servers.
+
+The third domain proxies to the upstream ``TLS`` server based on the requested ``SNI`` address, but does no ``TLS`` termination itself.
+
+The composition also starts an Envoy proxy client which listens on http://localhost:20000.
+
+The client proxy has no ``TLS`` termination but instead proxies three routed paths -
+``/domain1``, ``/domain2`` and ``/domain3`` - to the ``SNI``-enabled proxy.
+
+.. code-block:: console
+
+ $ pwd
+ envoy/examples/tls-sni
+ $ docker-compose build --pull
+ $ docker-compose up -d

+ tls-sni_proxy-client_1 /docker-entrypoint.sh /usr ... Up 0.0.0.0:20000->10000/tcp
+
+Step 2: Query the ``SNI`` endpoints directly with curl
+******************************************************
+
+You can use curl to query the ``SNI``-routed ``HTTPS`` endpoints of the Envoy proxy directly.
+
+To do this you must explicitly tell curl to resolve the ``DNS`` for the endpoints correctly.
+
+Each endpoint should proxy to the respective ``http-upstream`` or ``https-upstream`` service.
+
+.. code-block:: console
+
+ $ curl -sk --resolve domain1.example.com:10000:127.0.0.1 \
+ https://domain1.example.com:10000 \
+ | jq -r '.os.hostname'
+ http-upstream1
+
+ $ curl -sk --resolve domain2.example.com:10000:127.0.0.1 \
+ https://domain2.example.com:10000 \
+ | jq -r '.os.hostname'
+ http-upstream2
+
+ $ curl -sk --resolve domain3.example.com:10000:127.0.0.1 \
+ https://domain3.example.com:10000 \
+ | jq -r '.os.hostname'
+ https-upstream3
+
+Step 3: Query the ``SNI`` endpoints via an Envoy proxy client
+*************************************************************
+
+Next, query the Envoy proxy client using the routed paths.
+
+These route via the ``SNI`` proxy endpoints to the respective ``http-upstream`` or
+``https-upstream`` services.
+
+.. code-block:: console
+
+ $ curl -s http://localhost:20000/domain1 \
+ | jq '.os.hostname'
+ http-upstream1
+
+ $ curl -s http://localhost:20000/domain2 \
+ | jq '.os.hostname'
+ http-upstream2
+
+ $ curl -s http://localhost:20000/domain3 \
+ | jq '.os.hostname'
