Localstack start command returning 'Enable privileged port mapping' error

PJ_Simpson · October 3, 2023, 7:59am

I have been using community version without issue, however upon receiving my pro key and starting localstack like so:

LOCALSTACK_API_KEY=XXXXXX localstack start

I encounter the following error:

2023-10-03T08:36:04.036 ERROR --- [-functhread2] localstack.utils.bootstrap : Error while starting LocalStack container: Docker process returned with errorcode 125
docker: Error response from daemon: Ports are not available: exposing port TCP 127.0.0.1:443 -> 0.0.0.0:0: not allowed as current user.
You can enable privileged port mapping from Docker -> Settings... -> Advanced -> Enable privileged port mapping.
time="2023-10-03T08:36:04+01:00" level=error msg="error waiting for container: "

Privileged port mapping IS enabled in my Docker Desktop instance.

If I attempt to start the stopped container in the DD UI, it throws the same error, however if I used the re-start button, it appears to run fine:

…but the localstack webapp cannot connect

Could not connect to running LocalStack instance. Make sure LocalStack is running and that its endpoint is accessible from this browser.
Update the endpoint URL in the above Settings if you are running LocalStack on a non-standard port or on a remote host.

Any interactions with the localstack instance fail with the following error:

Could not connect to the endpoint URL: "http://localhost:4566/..."

This includes scripts, apps, etc which reliably work against the community version.

I can switch back to the community version and start it with the CLI and it runs as expected.

Is anybody able to guide me as to where I might be going wrong? I was also wondering if this may be a bug in Docker ?

Will paste full DEBUG output below.

Docker version 24.0.6
Docker Desktop version 4.23.0

Hello!
It seems your docker daemon still thinks privileged port mapping is disabled, can you please double check and also restart Docker Desktop for good measure?

What happens if you run docker run --rm -p 443:443 alpine echo test for example, does this work?

Also, I would suggest updating to CLI version 2.3.1, since we fixed some unnecessary flags there.

As last workaround from our side, you can set GATEWAY_LISTEN=:4566. While this should prevent LS from trying to expose port 443 to the host, it is more a fix for the symptoms, rather than the issue (which seems to be docker denying privileged port forwardings).

PJ_Simpson · October 3, 2023, 10:52am

Hi @dfangl , thanks so much for looking into this so promptly.

I can confirm that workaround is good, and I am able to interact with Pro features, so thanks again for that!

I can get docker to map those ports outside of the LocalStack process:

docker run --rm -p 443:443 alpine echo test

Upgrading the CLI hasn’t helped (I also attempted this before and after a restart of Docker Desktop):

This error message now differs from the one above. There was some issue with Docker Desktop < 4.16.2, described here: Error response from daemon: is vmnetd running? · Issue #6677 · docker/for-mac · GitHub Although it seems some people with later versions also experience it.

Can you check your docker desktop version, and also check out the fixes described at the end of the linked issue? (Specifically this one: Error response from daemon: is vmnetd running? · Issue #6677 · docker/for-mac · GitHub)

PJ_Simpson · October 3, 2023, 12:39pm

@dfangl perfect, that’s done the trick!

FWIW: I am on the latest version of DD (4.23.0)

sudo /Applications/Docker.app/Contents/MacOS/install vmnetd

… and after that the command to start LocalStack Pro version succeeds as expected.
