 It installs a docker-compose.proxy.yaml which adds proxy capabilities to DDEV v1.19.4+
 
+With this setup you should be able to use `webimage_extra_packages` against a proxy, and you should also be able to `ddev ssh` into the web container and use curl and see it using the proxy. `curl -v -I <target>` is a good test. See also the [tests](tests/test.bats).

+Details about how to lab-test this are in [Lab-testing a proxied environment](lab-testing.md).

+You can also find public proxies of varying reliability at [spys](https://spys.one/free-proxy-list/US/) and other places, and of course you would never trust them with any traffic, but they're useful for testing.

+# Lab-testing a proxied environment
+
+I used Parallels on macOS for the test lab.
+
+* Created a Parallels VM proxy server with a simple tiny Ubuntu 22.04 server running [tinyproxy](https://tinyproxy.github.io/), which was shockingly simple to install and configure (`apt-get install tinyproxy`), very small configuration changes ([example /etc/tinyproxy/tinyproxy.conf](tinyproxy.conf)). I'll call this machine "proxy".
+* Added an additional "host-only" interface in Parallels and added it to the proxy VM
+* Set up Parallels to use the name of the VM as its hostname. You should now be able to `ping proxy.host-only`
+* Used an existing (different) Ubuntu 22.04 Parallels VM as the ddev/docker environment and added the host only interface to it.  I'll call this machine "workstation".
+* Turned off the primary network interface in the workstation, so it had no direct network connectivity, verified that ping of internet addresses failed.
+* Configured the workstation VM with system-wide proxy settings using the regular Ubuntu network setting GUI (in this case HTTP/HTTPS proxies using proxy.host-only:8888).
+* Configured the Firefox browser on "workstation" to use the system-configured proxy and verified that it could now operate.
+* Verified that curl against internet https locations now worked on the "workstation".
+* Configured the docker server as in step 2 above, and verified that `docker pull ubuntu` now worked on "workstation" using the proxy.
+* Configured the docker client as in step 3 above and verified that proxy setup was now right in the container by `ddev start`, `ddev ssh`, and using curl inside the container against an HTTPS website.
+* Added the .ddev/web-build/Dockerfile from step 4 into the ddev project on the "workstation" and `ddev start`, then `ddev ssh` and `sudo apt-get update` and saw the update happen successfully, all using the proxy.
