Temporal dev server running in docker unreachable

[sarnikowski]

Expected Behavior

Temporal is accessible on http://localhost:7233 when using dev setup described in https://github.com/temporalio/samples-server/blob/7c22fa05a6f4c25358ac4623d671f5573ecdf857/compose/docker-compose-dev.yml

Actual Behavior

Cannot reach the server. Using the Go-SDK i keep getting "failed reaching server: context deadline exceeded". Using the temporal CLI, it hangs when trying to reach the server.
Note that the UI is available and accessible at localhost:8233.

Steps to Reproduce the Problem

1. Copy the contents of https://github.com/temporalio/samples-server/blob/7c22fa05a6f4c25358ac4623d671f5573ecdf857/compose/docker-compose-dev.yml to a local file. Let's call it docker-compose.dev.yml
2. Start the service using docker compose -f docker-compose.dev.yml up -d
3. Run the following command:

   docker run --rm temporalio/admin-tools:1.28.3 \
          temporal operator namespace describe default \
          --address localhost:7233

My suspicion is that this is an issue with docker, since the issue started to appear after doing a system upgrade.

Could you send a gist of a reproduction?

In step 3 of your example: localhost is referencing the admin-tools container not the host machine.
