Introduce a Makefile that builds libtoastyfs.a and libtoastyfs.so from the client-side sources (client, tcp, byte_queue, message, basic) so external programs can link against the ToastyFS client API in include/toastyfs.h. Add a Dockerfile and docker-compose.yml that spin up a 3-node ToastyFS server cluster on a private bridge network with ports 8081-8083 exposed on the host. Include cluster.sh as a convenience wrapper (up/down/status/ logs/run) — the "run" sub-command builds the library, compiles a user- supplied C source against it, starts the cluster, and executes the binary. Add examples/example.c demonstrating synchronous PUT, GET, DELETE, and a NOT_FOUND verification. https://claude.ai/code/session_019DVhmc25jfzcHnmdNxzib2

# cluster.sh - Spin up a ToastyFS cluster and optionally build & run
|
|
# an application that links against libtoastyfs.
|
|
#
|
|
# Usage:
|
|
# ./cluster.sh up Start the 3-node cluster
|
|
# ./cluster.sh down Stop the cluster
|
|
# ./cluster.sh status Show cluster status
|
|
# ./cluster.sh logs [node] Tail cluster logs (or a single node)
|
|
# ./cluster.sh run <source.c> Build the library, compile <source.c>
|
|
# against it, start the cluster, run the
|
|
# binary, then tear down the cluster.
|
|
#
|
|
# The cluster exposes ports 8081-8083 on localhost, mapped to the three
|
|
# server nodes. Client applications should connect to:
|
|
# 127.0.0.1:8081 127.0.0.1:8082 127.0.0.1:8083
