canic-installer

Published installer and release-set tooling for downstream Canic workspaces.

Who should use this crate directly

Use this crate directly when you need:

• the installed Canic release/build binaries in CI or local automation
• root release-set staging or install flows from a published tool package
• the canonical downstream installer/build surface without cloning the full repo

If you just want a normal local setup, prefer the tagged install script below. That is still the simplest entry path for most users.

For the full local setup path, prefer the shared tagged installer script from the Canic repo:

curl -fsSL https://raw.githubusercontent.com/dragginzgame/canic/v0.27.16/scripts/dev/install_dev.sh | bash

That script bootstraps Rust when needed, installs the pinned internal toolchain, canic-installer, the required wasm/Candid utilities, and dfx when it is missing. This crate README documents the thinner installed-binary surface below.

What this crate is not

This crate is not a general deployment framework and it is not the main Canic application facade. It owns the published build/install/release utilities for the standard Canic topology, especially root/bootstrap/store flows.

This crate owns the public thin-root build and staging path:

• build visible canister artifacts through canic-build-canister-artifact
• build the implicit bootstrap wasm_store through canic-build-wasm-store-artifact
• emit .dfx/<network>/canisters/root/root.release-set.json
• stage the ordinary release set into root
• resume root bootstrap
• drive the local root install flow, including one clean local dfx restart attempt when dfx ping local fails

Typical installed binaries:

• canic-build-canister-artifact
• canic-build-wasm-store-artifact
• canic-emit-root-release-set-manifest
• canic-list-install-targets
• canic-stage-root-release-set
• canic-install-root
• canic-install-reference-topology

Build-profile selection is explicit:

• CANIC_WASM_PROFILE=debug builds raw debug wasm
• CANIC_WASM_PROFILE=fast builds the middle shrunk local/test/demo lane
• CANIC_WASM_PROFILE=release builds the shipping/install lane

If unset, installer/build binaries default to release.

When the Rust workspace root and the DFX/project root differ, set both:

• CANIC_WORKSPACE_ROOT for Cargo, canic.toml, and canister manifests
• CANIC_DFX_ROOT for dfx.json, .dfx, and emitted artifacts

If canister crates live somewhere other than the default canisters/ directory, the installer first tries to discover them from Cargo workspace metadata. Zero extra config is needed when package names still follow the normal canister_<role> convention, even if manifests live in nested paths.

If you need the local install target list from canic.toml directly, canic-installer now exposes it as one public CLI:

canic-list-install-targets

That command prints one install target per line for the single subnet that owns root, including root first and then the ordinary roles for that subnet. The implicit bootstrap wasm_store is still excluded. To point at a specific config path explicitly:

canic-list-install-targets path/to/canic.toml

If you need to override discovery explicitly, set:

• CANIC_CANISTERS_ROOT for the canister crate root relative to CANIC_WORKSPACE_ROOT

or point CANIC_CONFIG_PATH at the real canic.toml path and the installer will infer the canister-manifest root from that config location.

If a package name does not follow canister_<role>, declare the role mapping in Cargo.toml:

[package.metadata.canic]
role = "project_ledger"
