`bun install --frozen-lockfile` is exceptionally slow in docker [bun 1.1.4]
What version of Bun is running?
1.1.4+fbe2fe0c3
What platform is your computer?
Linux 5.15.146.1-microsoft-standard-WSL2 x86_64 x86_64
What steps can reproduce the bug?
Use this minimal Dockerfile with a nestjs project
FROM oven/bun:1.0.14 as base
WORKDIR /usr/src/app
COPY package.json bun.lockb ./
FROM base as dev
RUN bun i --frozen-lockfile
COPY . .
CMD ["bun", "start"]
FROM base as prod
RUN bun i --production --frozen-lockfile
RUN bun i -D @nestjs/cli
COPY . .
RUN bun run build
EXPOSE 3000
CMD ["bun", "start:prod"]
And see a fresh build take 5 minutes for a bun ci

What is the expected behavior?
Fast install, doing the same on my host machine takes a few seconds max even without cache
What do you see instead?
300+ second install

I am having the same issue in my docker image, I tried building from base image oven/bun:1-alpine and it takes forever to install my svelte app dependencies.
If anyone is stuck at this, as a work-around for this, I install the dependencies using yarn, then build and run using bun.
I added
[install.lockfile]
print = "yarn"
to bunfig.toml file in project's root, this makes bun create yarn.lock file as well as bun.lockb file.
Then I update my docker file to look like this:
# Install using yarn, as bun install has problems with docker
FROM node:lts-alpine AS install
WORKDIR /app
COPY package.json .
COPY yarn.lock .
RUN --mount=type=cache,target=/usr/local/share/.cache yarn install --freeze-lockfile --verbose
# Build and run using bun
FROM oven/bun:1-alpine
WORKDIR /app
COPY --from=install /app /app
COPY . .
RUN bun run build
CMD bun ./build/index.js
The --mount part in the install command is used to mount yarn cache as a cache-mount, this greatly reduces resulting image size (effectively removes cache from the image), and makes subsequent builds a lot faster.
The end result is that docker build now finishes in a couple of minutes (from a clean state without any cached images).
