[Bug] web ui shows Connection Lost

[YuriyGavrilov]

Bug Description

Briefly describe the unexpected behavior or performance regression. What happened that wasn’t supposed to?

Just run bacalhau serve --node-type requester,compute --web-ui

Expected Behavior

Detail what you expected to happen instead of the bug.

Steps to Reproduce

1. Step one to reproduce run bacalhau serve --node-type requester,compute --web-ui
2. Step two open browser
3. Step three see message
4. (run compute node ) bacalhau serve --node-type=compute --orchestrators=192.168.0.105
5. see that there is no nodes in web UI

but there is one and second on requestor

ENG-276 [Bug] web ui shows Connection Lost

[YuriyGavrilov]

also don't know how to run in docker mode
Node n-f4ce17b5: does not support docker, only wasm"]

[aronchick]

i'm so sorry, we're on it!

For your second problem, it's likely you don't have docker running on the machine you're running on.

[wdbaruni]

Hy Yuriy,

Issue 1:

I wasn't able to re-produce the issue. I do see from the screenshot the webui is having trouble connecting to the orchestrator node. What url are you using to reach the webui? Is it 0.0.0.0:8438 where the orchestrator is deployed locally? or a remote node?

If you are calling the webui on a remote node, and I'll guess the node is 192.168.0.105, try and see if this works bacalhau serve --node-type requester,compute --web-ui --config WebUI.Backend=192.168.0.105:1234.

If this works, it is just telling the frontend to connect to the orchestrator at 192.168.0.105:1234 instead of the default endpoint 0.0.0.0:1234 which would only work for local deployments. More documentation is required from our end.

Issue 2:

The panic you are getting seems to originate from the code where we try to query docker's daemon information. It seems we are not handling edge cases well when the returned information is not what we expect. This code hasn't change in while, and it seems the bug just wasn't triggered all this time. Do you mind providing us with more information about your setup? Mainly the output of docker version

bacalhau/pkg/docker/docker.go

Lines 233 to 241 in 3fd303d

	func (c *Client) SupportedPlatforms(ctx context.Context) ([]v1.Platform, error) {
	version, err := c.ServerVersion(ctx)
	if err != nil {
	return nil, err
	}
	engineIdx := slices.IndexFunc(version.Components, func(v types.ComponentVersion) bool {
	return v.Name == "Engine"
	})

i'm so sorry, we're on it!

For your second problem, it's likely you don't have docker running on the machine you're running on.

Thanks for helping 🙏🏻 @aronchick @wdbaruni

@aronchick yep you was right, regular use Podman so I run docker on second node. checked but actually same results.

@wdbaruni

1. run the node with bacalhau serve --node-type=compute --orchestrators=192.168.0.105
2. run the job bacalhau docker run ubuntu echo hello --api-host=192.168.0.105
3. receive:
