Trying to dockerize a Bun app, I faced those 3 following issues when running my container:

bun-app-1  | error: Cannot find module "@node-rs/argon2-wasm32-wasi" from "/app/node_modules/@node-rs/argon2/index.js"

bun-app-1  | error: Cannot find module "@node-rs/bcrypt-wasm32-wasi" from "/app/node_modules/@node-rs/bcrypt/binding.js"

bun-app-1  | error: Cannot find module "@node-rs/argon2-linux-arm64-gnu" from "/app/node_modules/@node-rs/argon2/index.js"

bun-app-1 exited with code 1

Locally, everything works fine (bun run src/index.tsx in my terminal). The moment I try to run this with Docker, it crashes.

I’m newbie with Docker so I’m not sure if this error is related to my docker config. Don’t hesitate to correct me on this point or guide me in a better way to track issues (I know that bcrypt and argon2 are related to oslo, which is recommended to use with lucia).

Here below are my docker-compose and dockerfiles:

docker-compose.yml
