stellar-cli-docker

Docker images for the Stellar CLI.

Also compatible as a SEP-58 image image for reproducible Stellar contract builds.

Each image:

• Pins its base via the official rust:<version>-<suffix> multi-arch index digest. See RELEASE.md → Base image policy for how the version + suffix are chosen per release.
• Pins the Rust toolchain via RUSTUP_TOOLCHAIN, baked in so an in-source rust-toolchain.toml cannot silently swap it.
• Pins stellar-cli to a specific upstream commit, installed with cargo install --locked.
• Ships with the wasm32v1-none target preinstalled.
• Sets WORKDIR /source and ENTRYPOINT ["stellar"].

Quick start

Pull a published image (per-host arch):

docker run --rm docker.io/stellar/stellar-cli:latest --version

Confirm the rustc version used:

docker run --rm --entrypoint rustc docker.io/stellar/stellar-cli:latest --version

Build a contract by mounting the contract directory at /source:

docker run --rm -v "$PWD:/source" docker.io/stellar/stellar-cli:latest contract build --locked

The image exposes four well-known paths:

Path	What
/source	WORKDIR. Bind-mount your contract here.
/config	STELLAR_CONFIG_HOME. Mount to persist network and identity configuration.
/data	STELLAR_DATA_HOME. Mount to persist CLI data.
/stellar	Home for user stellar (UID 1000). Mount to persist the cargo cache (see below).

The image runs as user stellar (UID 1000) with /stellar as the home directory. CARGO_HOME resolves to /stellar/.cargo inside the container, which is wiped on exit by default.

To reuse cargo's registry index, git checkouts, and crate sources across runs — and to make the image work under --user "$(id -u):$(id -g)" on Linux hosts whose UID is not 1000 — mount a writable host directory at /stellar:

mkdir -p /tmp/myproject
docker run --rm \
--user "$(id -u):$(id -g)" \
-v /tmp/myproject:/stellar \
-v "$PWD:/source" \
docker.io/stellar/stellar-cli:latest contract build --locked

Verifiable builds (SEP-58)

For verifiable references, always pin to a per-arch single-architecture digest (@sha256:…) — it is the only stable reference. Never use a tag or a multi-arch manifest list digest in bldimg:

# Find the per-arch digest for the architecture you used to build.# Pick any of the manifest-list tags from the release notes,# e.g. :26.0.0-rust1.94.0-slim-trixie, or the :26.0.0 alias:
docker buildx imagetools inspect docker.io/stellar/stellar-cli:26.0.0

Record the per-arch digest in your contract's bldimg metadata. A verifier will pull the same per-arch image, run the same docker run invocation, and compare the resulting WASM sha256.

Repo layout

Path	What
Dockerfile	Two-stage builder + runtime, args-driven.
builds.json	Source of truth for which (stellar-cli, rust base key) pairs we publish.
builds.schema.json	JSON Schema for builds.json.
docker/README.md	Docker Hub overview. The publish workflow pushes this to the repository's full_description on each release.
scripts/build_image.py	Local single-image build.
scripts/validate_json.py	Validates every *.json for sorted keys and builds.json against the schema.
scripts/refresh.py	For one --stellar-cli-version: picks the rust base labels, resolves the upstream cli ref and each base's index digest, and appends the fully-qualified pins <label>@<digest> (append-only; already-published pins are retained).
scripts/verify_image.py	Consumer-facing verifier. Wraps gh attestation verify for both the SLSA build provenance and the SPDX SBOM attestations against a per-arch image digest.
scripts/lib/	Shared Python helpers imported by the other scripts (builds.json IO, semver/key parsing, subprocess + adapter wrappers).

Local development

# Validate builds.json.
./scripts/validate_json.py
# Build a local image for a declared (cli, rust base) pair. The rust base is# given as the label plus its pinned digest (copy the pin from builds.json).
./scripts/build_image.py --stellar-cli-version 26.0.0 \
--rust-version 1.94.0-slim-trixie \
--rust-image-digest sha256:f7bf1c266d9e48c8d724733fd97ba60464c44b743eb4f46f935577d3242d81d0
# Smoke-test the built image.
docker run --rm stellar-cli:26.0.0-rust1.94.0-slim-trixie --version
docker run --rm stellar-cli:26.0.0-rust1.94.0-slim-trixie contract build --help
# Resolve + append rust base pins and the cli ref for a version (maintainer task).
./scripts/refresh.py --stellar-cli-version 26.1.0 --dry-run

Requirements: docker (with buildx) and uv.

Releasing

Maintainers: see RELEASE.md for the end-to-end release process — how builds.json works, the PR-driven release flow that fires the publish workflow when a GitHub Release is published, the published tag scheme, and how to verify a freshly published image.
