Python-typed Rust modules for workflow automation — SSH, containers, files, HTTP, packages, services, templates

cutip-blocks

Rust-backed workflow blocks for CUTIP. Write Python, execute Rust.

Every function you call from cutip_blocks is a compiled Rust binary under the hood — SSH via russh, Docker/Podman via bollard, HTTP via reqwest, YAML/JSON via serde. Zero Python dependencies. The Python GIL is released during all I/O.

Install

pip install cutip-blocks

Modules

Module	Rust crate	What it does
ssh	russh	Persistent SSH sessions — connect(), exec(), probe()
kubectl	serde	Kubernetes ops over SSH — get, exec, find_pod, patch_deployment, patch_file_from_pod
container	bollard	Docker/Podman — start, stop, remove, exec, pull
file	std::fs + serde	copy, copy_tree, read/write_json, read/write_yaml, replace
http	reqwest	get, post, put, delete with JSON + TLS toggle
network	bollard	create, remove, exists
service	reqwest + bollard	poll_until_ready, wait_for_exit
validate	std	path_exists, env_var_set, ip_valid
config	string ops	render_template, substitute_vars

Usage

SSH + kubectl (remote VM operations)

from cutip_blocks import ssh, kubectl

with ssh.connect(host="10.0.0.1", username="root", password=pw) as sesh:
    sesh.probe()  # verify connectivity

    kube = kubectl.connect(sesh, namespace="prod")
    kube.get("deployment", name="web")
    kube.find_pod(name_prefix="web")

    password = kube.get_secret_value(secret="db-creds", key="password")
    kube.exec(target="deploy/web", cmd="cat /app/config.py")

    kube.patch_file_from_pod(
        deployment="web",
        source_file="/opt/app/handler.py",
        dest_dir="/root/patches",
        replacements={"old_value": "new_value"},
    )

    kube.patch_deployment(
        deployment="web",
        volume_name="config-override",
        host_path="/root/patches/handler.py",
        mount_path="/opt/app/handler.py",
    )

Container management

from cutip_blocks import container

rt = container.connect()  # auto-detect Docker/Podman
rt.pull("nginx", tag="latest")
rt.start("my-container")
result = rt.exec("my-container", "nginx -t")
print(result.stdout)
rt.stop("my-container")
rt.remove("my-container")

File operations

from cutip_blocks import file

data = file.read_json("config.json")
file.copy_tree("src/", "build/deps/")
file.replace("config.yaml", "old_value", "new_value")
file.write_yaml("output.yaml", {"key": "value"})

HTTP

from cutip_blocks import http

resp = http.post("https://api.example.com/token",
                 json={"username": "admin", "password": "secret"},
                 verify_tls=False)
token = resp.json()["access_token"]
