The Singularity Sync utility rebuilds Docker containers as Singularity containers. It does so by parsing a manifest file containing a list of Docker images. Below is an example of a manifest file.
---
docker:
- bids/validator
- brownbnc/xnat-tools
- poldracklab/fmriprep
- poldracklab/mriqc
As of this writing (2020/08/26) there is only support for images from the official Docker Hub. The repositories are represented in ${org}/${respository} form.
To install Singularity Sync install rust.
Build using cargo:
cargo build --release
Run the resulting executable:
./target/release/singularity_sync
Development follows a standard rust workflow. Most everything is done through cargo.
Build development version with cargo:
cargo build
Run development version:
cargo run -- -h
Format with cargo:
cargo fmt
Lint with cargo:
cargo clippy
