At the moment the following appears to work: alphanet.sh start --rpc-port 127.0.0.1:8732.

Note --rpc-port and NOT --rpc-addr, this is a special case option in alphanet.sh.

This will insert a entry:

  ports:
    - "127.0.0.1:8732:8732"

into the generated docker-compose.yaml, causing the RPC to be exposed to localhost at the specified port -- it was already exposed as usual with --rpc-addr in the tezos-node itself, but only inside the container.

This is documented, sort of:

./scripts/alphanet.sh start [--rpc-port <int>] [OPTIONS]
   Launch a full Tezos alphanet node in a docker container
   automatically generating a new network identity.
   OPTIONS (others than --rpc-port) are directly passed to the
   Tezos node, see './scripts/alphanet.sh shell tezos-node config --help'
   for more details.
   By default, the RPC port is not exported outside the docker
   container. WARNING: when exported some RPCs could be harmful
   (e.g. 'inject_block', 'force_validation', ...), it is
   advised not to export them publicly.

Even though a port was expected (<int>), --rpc-port 127.0.0.1:8732 happens to work, and should be generally safer.

To start rpc at 8732 port use

./alphanet.sh start --rpc-port 8732

As mentioned in alphanet.sh script file, you can use --rpc-port option in the start command as mentioned below, specifying the port.

./alphanet.sh start [--rpc-port <int>] [OPTIONS]"

Launch a full Tezos alphanet node in a docker container" automatically generating a new network identity." OPTIONS (others than --rpc-port) are directly passed to the" Tezos node, see '$0 shell tezos-node config --help'" for more details." By default, the RPC port is not exported outside the docker" container. WARNING: when exported some RPCs could be harmful" (e.g. 'inject_block', 'force_validation', ...), it is" advised not to export them publicly."

    As I said in my answer, it is generally going to be safer to use --rpc-port 127.0.0.1:8732, when the RPC need not be accessible from any other host besides the docker host.
