VM Agent is an agent that runs in an Azure VM and selectively exposes some APIs of the blockchain client running alongside it.
This project features,
-
A minimalistic JSON-RPC 2.0 client implementation in Clojure. Check this file for example usage.
-
Pedestal conditional interceptors and content negotiation.
-
Install the Clojure CLI tools, preferably in a *nix environment (Windows Subsystem for Linux works fine.) Outside WSL, Windows support is experimental at this point.
-
Build the project and create a Docker image in one step,
> clojure -A:pack mach.pack.alpha.jib \ --image-name $DOCKER_REGISTRY/vm-agent:0.1.0 \ --image-type docker \ -m vm-agent.server$DOCKER_REGISTRYis any registry where you want to host the image. For Azure Container Registry, use<registry>.azurecr.io. -
Start the server,
> docker run $DOCKER_REGISTRY/vm-agent:0.1.0 -
Try one of the examples.
curl -i \
-H 'Accept: application/json' \
http://localhost:8890/besu/block-numberNote: There are known networking limitations when running Docker on Windows. Try these workarounds,
- Run Docker in a Vagrant VM.
- Run cURL in a container that is attached to the same network.
Currently, these APIs are exposed,
