Emscripten docker image for compiling crypt4gh applications

This implementation was extracted from swift-browser-ui.

This container makes it easy to compile crypt4gh applications built with emscripten into wasm without installing dependencies locally.

Stack

The provided docker image is an extension of emscripten/emsdk official docker image.

Included libraries

• libsodium
• openssl
• libcrypt4gh
• libcrypt4gh-keys

How to use this container

Build the image with

docker buildx build .

or download it

docker pull ghcr.io/cscfi/docker-emscripten-crypt4gh:latest

Build your application

docker run --rm -it --mount type=bind,source=${YOUR_APPLICATION_SOURCE_CODE},target=/src/ ghcr.io/cscfi/docker-emscripten-crypt4gh:latest YOUR-MAKEFILE-COMMAND-HERE

Extras

You can provide argument variables to change which library versions get built.

emscripten, libsodium, and openssl versions can be changed with --build-arg by changing the value of EMSCRIPTEN_VERSION, LIBSODIUM_VERSION, EMSDK_IMAGE and OPENSSL_VERSION.

NOTE: To build only ARM images use -arm in version tag and for ARM built images. For example EMSDK_IMAGE --build-arg="EMSDK_IMAGE=<local-registry>/emscripten/emsdk" --build-arg="EMSCRIPTEN_VERSION=3.1.21-arm" instructs to use locally build emsdk:3.1.21-arm container.
