NX Cloud agent: dotnet is not installed - setup-dotnet action is ignored

[roldengarm]

Current Behavior

My repo depends on .NET as we're using nx-dotnet.
I'm starting a ci-run on 8 linux-medium-js and then have below two actions

 - uses: actions/setup-dotnet@v4
    with:
      dotnet-version: '8.0.100'
  - run: npm ci

Then, npm ci fails, as dotnet is not installed on the runner:

nx g @nx-dotnet/core:restore
27   
28   /bin/sh: 1: dotnet: not found

Expected Behavior

It installs dotnet on the agent before running npm ci

Additional Information

I guess another workflow action has to be added to this repo?
Or alternatively, can we customise the docker image used for the runner?

[EelcoLos]

can concur, this happens to me as well: https://github.com/EelcoLos/nx-tinkering/actions/runs/10520973969/job/29150814666

and
https://cloud.nx.app/cipes/66c831638af1d9575b458e83?step=start-agent-step#step-list-pane

@EelcoLos I'm pretty sure it's currently just not supported.
See the workflow of the cloud runner here
There are only templates for js and jvm.

I did see a topic there about Docker, which could solve the problem, but that's Enterprise only at the moment.

[EelcoLos]

if we look at https://github.com/nx-dotnet/nx-dotnet/blob/master/.github/workflows/pr.yml & https://github.com/nx-dotnet/nx-dotnet/blob/master/.github/workflows/main.yml, we can see which workflows are used there and are possible now. Still, the question remains.

Edit: Also, a while ago on a stream, there was mention of Launch Templates: https://nx.dev/ci/reference/launch-templates

@roldengarm
I tried that: https://cloud.nx.app/cipes/66c836274f3e8224f888f428?step=start-agent-step#step-list-pane with https://github.com/EelcoLos/nx-tinkering/blob/6f7d45baecd473f0e40c0dd81dd3a335a5b6350f/.nx/workflows/agents.yml

[roldengarm]

@EelcoLos ah, didn't see the nx-dotnet templates! This is not documented I believe.
So, it worked for you with this ci.yml file, where you point to your custom agent, which installs dotnet, right?

/edit: @EelcoLos that works indeed! I had to swap dotnet install and npm install but that's fine.

[FrozenPandaz]

Correct! You'll need to define your own custom launch templates to use dotnet in Nx Agents.
