Running the Dashboard Docker Image

[christophwille]

docker pull mcr.microsoft.com/dotnet/nightly/aspire-dashboard:8.0.0-preview.3 
docker run --rm -it -p 18888:18888 -p 4317:18889  mcr.microsoft.com/dotnet/nightly/aspire-dashboard:8.0.0-preview.3

When going to http://localhost:18888/, I get the following (fail) output from the console:

What am I missing? Should I be using a newer tag https://mcr.microsoft.com/v2/dotnet/nightly/aspire-dashboard/tags/list? Current tags as of writing this issue:

{
    "name": "dotnet/nightly/aspire-dashboard",
    "tags": [

There are bugs in the current dashboard image when run without a resource server. The image hasn't been updated since the original push (preview3). When we get another update it should be runnable as a standalone otlp server (preview4/latest)

I have a PR out to update it to a build from today: dotnet/dotnet-docker#5203

Are these updates going to be automated?

I can confirm that

docker pull mcr.microsoft.com/dotnet/nightly/aspire-dashboard:8.0.0-preview.4
docker run --rm -it -p 18888:18888 -p 4317:18889  mcr.microsoft.com/dotnet/nightly/aspire-dashboard:8.0.0-preview.4

Now works for logs & traces from a standard OTLP-exporting ASP.NET 8.0 application

Excellent @christophwille !

@drewnoakes, I'm getting these "DashboardClient is disabled" errors when attempting to use Aspire.Dashboard.exe standalone as discussed in #1774 (comment). So I'll wait for preview4 then.

[drewnoakes]

If you don't want to wait and just need a binary, you could build it yourself from this repo to test it out. Or try the docker image mentioned above.

[davidfowl]

@KalleOlaviNiemitalo use the preview 4 version of the image. Look at the command above
