build: optimize dockerfile by evilrobot-01 · Pull Request #4 · use-ink/docker-images

evilrobot-01 · 2025-04-21T14:31:05Z

Updates the ci Dockerfile to:

use the latest stable version of Rust (1.86)
standardise on a single version of nightly
use stable2503 release branch of the Polkadot SDK
allow (mostly) building on ARM platforms
split rustup and cargo install into separate layers for easier disk usage analysis
perform cleanup on each layer
use updated url for cargo-contract
merge the codecov tasks into a single layer
switches to using stable as the default toolchain

Note:

self-published to https://hub.docker.com/r/evilrobot/useink/tags for use in related PR (ci: remove toolchain adjustments ink#2484), showing a reduction in compressed size from 3.27GB (https://hub.docker.com/r/useink/ci/tags) to 1.32GB. The container image should be as small as possible, both for pulling speed but also due to the limited space on a GitHub runner. https://github.com/evilrobot-01/use-ink-docker-images/actions shows the image builds/publishes.
See ci: remove toolchain adjustments ink#2484 for efforts there to maximise space in each runner before the image is pulled/run.

Ideally revive should provide an arm64 binary for usage within Docker on apple silicon. Simply ignored on non-amd64 platforms for now, which should only affect ink integration tests when built on a Mac AFAIK.

An issue can be opened on revive to add Linux arm64 builds so that it can be used within containers on a Mac.

Updates the `ci` Dockerfile to: - use the latest stable version of Rust (1.86) - standardise on a single version of nightly - use stable2503 release branch of the Polkadot SDK - allow (mostly) building on ARM platforms - split rustup and cargo install into separate layers for easier disk usage analysis - perform cleanup on each layer - use updated url for cargo-contract - merge the codecov tasks into a single layer

A faster approach is to download from a GitHub source code archive at a specific commit and decompress. As these images are generated rarely, not sure its worth the effort.

-    cargo install --git https://github.com/paritytech/cargo-contract \
-      --locked --branch master && \
-    git clone https://github.com/paritytech/polkadot-sdk.git --depth 50 && \
+    cargo install --git https://github.com/use-ink/ink-node --branch main --force --locked && \


Could be replaced with 'latest' prebuilt ink-node and cargo-contract binaries to speed things up.
