Direzione di ricerca

Inizia dai punti di ingresso dei comandi kmcp deploy, install e build e riproduci i comandi e gli errori mostrati nel report. Done dovrebbe coprire il namespace e il comportamento d’uso richiesti, indicazioni più chiare per l’installazione e il build, la gestione corretta delle immagini e le istruzioni per raggiungere un server distribuito.

Scritto dal modello di indicizzazione a partire dal testo della issue.

Descrizione

--namespace should default to the current context, not default.

When i run:

$ kmcp deploy -n mcp
🚀 Applying MCPServer to cluster...
error: resource mapping not found for name: "test" namespace: "mcp" from "/tmp/mcpserver-165274223.yaml": no matches for kind "MCPServer" in version "kagent.dev/v1alpha1"
ensure CRDs are installed first
Error: failed to apply to cluster: kubectl apply failed: exit status 1
Usage:
  kmcp deploy [flags]

Flags:
      --args strings         Command arguments

We should not print the usage here, and we should give a better error like "run kcmp install first"

When I try to install:

$ kmcp install
🚀 Deploying KMCP controller to cluster...
Error: invalid controller version: version cannot be empty
Usage:
  kmcp install [flags]

Flags:
  -h, --help                     help for install
      --namespace string         Namespace for the KMCP controller (defaults to kmcp-system) (default "kmcp-system")
      --registry-config string   Path to docker registry config file
      --version string           Version of the controller to deploy (defaults to kmcp version)

How do I know what version to use?

Since I don't know, I followed https://github.com/kagent-dev/kmcp/tree/main?tab=readme-ov-file#controller-installation. This doesn't work either...

$ kubectl apply -f https://raw.githubusercontent.com/kagent-dev/kmcp/main/config/default/ --dry-run
W0730 08:10:43.389988 3498929 helpers.go:703] --dry-run is deprecated and can be replaced with --dry-run=client.
error: unable to read URL "https://raw.githubusercontent.com/kagent-dev/kmcp/main/config/default/", server reported 400 Bad Request, status code=400

Helm doesn't work either:

$ helm repo add kmcp https://charts.kagent.dev
Error: looks like "https://charts.kagent.dev" is not a valid chart repository or cannot be reached: Get "https://charts.kagent.dev/index.yaml": dial tcp: lookup charts.kagent.dev: no such host

Finally I guess the version is v0.1.0 and kmcp install --version v0.1.0 worked

Now I can run kmcp deploy and it runs successfully. I get ImagePullBackOff trying to pull "test:latest". its also pulling howardjohn/agentgateway:1752179558 which is not great since its not the real release.

I think I need to build so I tried:

$ kmcp build --docker --tag localhost:5000/my-mcp:latest
Building Docker image for python project...
Error: docker build failed: exit status 1
Usage:
  kmcp build [flags]

Flags:
      --docker               Build Docker image
  -h, --help                 help for build
  -o, --output string        Output directory or image name
      --platform string      Target platform (e.g., linux/amd64,linux/arm64)
  -d, --project-dir string   Build directory (default: current directory)
  -t, --tag string           Docker image tag

Global Flags:
  -v, --verbose   verbose output

I have no clue what this means. Add -v makes it a bit more clear:

$ kmcp build --docker --tag localhost:5000/my-mcp:latest -v
Building MCP server in: /tmp/tmp.GthxiQesz6/test
Detected project file: pyproject.toml
Starting build process...
Detected project type: python
Building Docker image for python project...
Running: docker build -t test:localhost:5000/my-mcp:latest .
ERROR: failed to build: invalid tag "test:localhost:5000/my-mcp:latest": invalid reference format
Error closing pipe: close |0: file already closed

Finally figure out it should be --output which was not intuitive to me but works I guess. I ran kmcp build --docker --output localhost:5000/my-mcp -v and it works.

Now I do:

$ kmcp deploy -n mcp --image localhost:5000/my-mcp:latest
🚀 Applying MCPServer to cluster...
mcpserver.kagent.dev/test configured
✅ MCPServer 'test' applied successfully
💡 Check status with: kubectl get mcpserver test -n mcp
💡 View logs with: kubectl logs -l app.kubernetes.io/name=test -n mcp

Again it fails. I guess the build only built, it didn't push. I manually run docker push localhost:5000/my-mcp:latest and it works this time.

Now its deployed.. now what? How do I reach it? Where is it? I happened to know its on port 3000 but others may not
