Running PXE at a custom port with aztec-sandbox is only possible by adding PORT: 8000 in docker-compose.yml

[porco-rosso-j]

I tried to run Sandbox at a different port instead of 8080. The command aztec-sandbox PXE_PORT=8000 is supposed to run it at port 8000 but it didn't work.

Sandbox log shows:
sandbox-aztec-1 | Aztec Server listening on port 8080

On frontend:

Instead, what's needed to make it work is to add PORT: 8000 as an env value for aztecprotocol/aztec image in .aztec/docker-compose.yml.

• I guess this is because the name of env variable used in yarn-project/aztec/src/bin/index.ts is just PORT, not PXE_PORT.
• Passing PORT=8000 to the command aztec-sandbox PXE_PORT=8000 also didn't work. Somehow it should be hard-coded in the docker-compose.yml file.
• I can find couples of other environment variables with slightly different names defined for the pxe port across different files.
  -- SANDBOX_PXE_PORT in aztec/docker-compose.yml
  -- AZTEC_PORT in aztec/src/cli/cli.ts

fixed here #6094

fyi

PXE_PORT is not the same as the port that the sandbox runs on. the PXE will run successfully in the right place if you specify PXE_PORT - you can check with docker ps

when this PR is merged (& included in a release) you will be able to optionally run the sandbox on a different port with SANDBOX_PORT and still run PXE on different ports too
