Recompiling takes too long inside docker container #270
Description
Hi! I'm playing with Rocket framework and created a monorepository with dockerized server service. I'm using cargo-watch for development mode and it works fine if I launching it locally. After saving source files it recompiles after ~0.68 seconds. But when I start server service inside docker container it takes too long. Near 2 minutes to restart.
This is my docker-compose.yml file:
services:
client:
image: ${APP_NAME}_client
build:
context: ./client
container_name: ${APP_NAME}_client
command: pnpm prod
restart: unless-stopped
networks:
- common
server:
image: ${APP_NAME}_server
build:
context: ./server
dockerfile: ./Dockerfile
container_name: ${APP_NAME}_server
command: cargo build -r && ROCKET_ENV=production cargo run -r
restart: unless-stopped
networks:
- common
nginx:
image: ${APP_NAME}_nginx
build:
context: ./nginx
container_name: ${APP_NAME}_nginx
ports:
- "80:80"
volumes:
- ./nginx/nginx.conf:/etc/nginx/conf.d/nginx.conf
depends_on:
- server
- client
networks:
- common
networks:
common:
name: ${APP_NAME}-network
driver: bridge
docker-compose.dev.yml
version: "3.9"
services:
client:
command: pnpm dev
stdin_open: true
tty: true
ports:
- 3001:3000
volumes:
- ./client/src:/usr/src/app/src
server:
build:
context: ./server
dockerfile: ./Dockerfile.dev
command: cargo watch -x run
volumes:
- ./server/src:/usr/src/app/src
- ./server/target:/usr/src/app/target
nginx:
volumes:
- ./nginx/nginx.dev.conf:/etc/nginx/conf.d/nginx.conf
And Dockerfile.dev:
FROM rust:1.67
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
RUN cargo install cargo-watch
COPY . .
As you can see, I've added src and target folder into the container volumes. I'm not sure if it's an issue with cargo-watch but it's really not obvious why it behaves like this. It looks like on each save it ignores cache and compiling from scratch. But container contains target folder. Does anyone know what's wrong there? Is this a cargo-watch issue?

Thanks!
