Hello flighters, I am new to flyte and trying to start 
demo
cluster in my local / system / laptop / machine but it is failing with below error:
Copy code
{"status":"Status: Downloaded newer image for <http://cr.flyte.org/flyteorg/flyte-sandbox-bundled:sha-1ae254f8683699b68ecddc89d775fc5d39cc3d84%22|cr.flyte.org/flyteorg/flyte-sandbox-bundled:sha-1ae254f8683699b68ecddc89d775fc5d39cc3d84">}
🧑‍🏭 booting Flyte-sandbox container
😬 Something went wrong: Failed to start Sandbox container 🐋, Please check your docker client and try again. 
Error: Error response from daemon: driver failed programming external connectivity on endpoint flyte-sandbox (5eaf6609c86e6d818291e2f060e42f8002dfd4e288393da6e01109cfa5a60bd7): listen tcp4 0.0.0.0:6443: bind: address already in use
I am on a Mac machine and I have a Docker Desktop which allows me to have locak Kubernetes to play with. As per this documentation of Kubernetes, 
6443
port is used by 
Kubernetes API server
. May I please know if and how I can change the port number for this flyte-sandbox?
update: 
flytectl sandbox start
command worked (kind of). It gives this nice shiny message:

Hi @Chandrashekhar Kotekar You should use 
flytectl demo start
as this is the preferred option going forward. It's complaining that port 6443 is already in use, could you check what process is using it? 
sudo lsof -i:6443

@David Espejo (he/him) Thanks for the quick reply. I get following output:
Copy code

do you have other containers running? 
docker ps
c
Yes.
Copy code
docker ps -a

might just need to disable the kubernetes cluster bundled in docker desktop for mac
we should definitely use a non-standard port though. 6443 might be too common. @Chandrashekhar Kotekar can you open an issue about this?
c
Sure, will open issue about it. Also - this port should be configurable through some config file.
Thanks for the help @David Espejo (he/him) and @jeev. As of now 
flytectl sandbox start
command has worked for me. So all good
f
Hi, any update to this?
j
@Fidhal Kotta: unfortunately not yet. any interest in taking a crack at a solution? 🙂
i
was facing the same issue on Windows 11 x64. disabling the local Kube-cluster that came with Docker Desktop did the trick.
c
Hi, I would like to start contributing to Flyte by fixing this issue. I have cloned flyte repository but not sure how this flyte sandbox image is built. Can someone please give me some hints / pointers to get started?
j
“make -C docker/sandbox-bundled build” should do it
c
thanks
