Need a worker to use Specific Container Image

[qkarpowi]

I currently have a scraper running as a worker in my aspire project. It uses .NET playwright which requires having the headless chromium browser installed. This is installed on the playwright recommended docker container image mcr.microsoft.com/playwright:v1.51.0-noble Is there a way I can force the web scrapping worker to use this container image so it will work in my production environment?

Current code:

var worker = builder.AddProject<Projects.Scraper>("scraperworker")
    .WithReference(postgresdb)
    .WaitFor(postgresdb);

What I'm hoping for:

var worker = builder.AddProject<Projects.Scraper>("scraperworker")
    .WithImage("mcr.microsoft.com/playwright:v1.51.0-noble")
    .WithReference(postgresdb)
    .WaitFor(postgresdb);

I am open to other solutions to this issue as well. If there's a way to install the headless browser after container startup or to add this project just as a container.

Does that image (mcr.microsoft.com/playwright:v1.51.0-noble) also contain dotnet?

This does work locally but produces a bug when deploying to azure.

Looks like the bug is documented here Azure/azure-dev#4713

But there is no solution yet.

There error I get is publishing container: failed to get dotnet target port: multiple dotnet port [] detected with dotnet publish output

Ah this might be because of how azd resolves the container port from the publish operation.

got a binlog or example I can check out? It's entirely possible to have multiple ports exposed in a container so without more context it's hard to say if it's a bug.

I think this is an azd issue. It's trying to resolve the port to use for a dotnet container publish and if there are multiple it seems like it blows up.
