I am handling four different ports / cases with Envoy:
- IPv6 http
- IPv4 http
- IPv6 https
- IPv4 https
For IPv6 and IPv4 the configuration is the same, whereas for http there is a different configuration than for https.
To realize this, I have split my envoy configuration into several snippets, and add them together during building of the container.
Here is what my new Dockerfile looks like:
COPY config /tmp/config
RUN cat /tmp/config/envoy_head.yaml /tmp/config/http_head_one.yaml /tmp/config/http_body.yaml /tmp/config/http_head_two.yaml /tmp/config/http_body.yaml /tmp/config/https_head_one.yaml /tmp/config/https_body.yaml /tmp/config/https_head_two.yaml /tmp/config/https_body.yaml /tmp/config/envoy_tail.yaml > /etc/envoy/envoy.yaml
my config folder contains several files which are combined into envoy.yaml
No need to search for “how to include files in yaml files”
Here is, for example, my envoy_head.yaml:
As you can see, it is rather simple
(NB: it ends with a newline, as do all the other files – when combining, this will give the desired result).
Don’t forget to build your container, running, for example:
docker-compose up –build
