Describe the Bug

Suddenly the step in Dockerfile that envolves turborepo RUN turbo prune --scope=web --docker, started to output this error:

ERROR [builder 8/8] RUN turbo prune --scope=web --docker                                     0.3s
------

Expected Behavior

Build normally

To Reproduce

I don't know how to reproduce because it's random. I don't change anything in the code. The only thing I made was keeping building de Dockerfile with docker compose (I don't know if it's related). Can someone help?

Reproduction Repo

I am getting exact same error.
I am using 1.7.0 version of turbo
Package Manager = NPM
OS = Mac
Bug is same as you have mentioned above

[digoburigo]

I resolved this issue for me by checking if my .dockerignore it's in the root folder containing the right files to ignore.
I will leave this issue open for now for more dicussion.

Can you please tell me which file you added in .dockerignore? If it's common then I will also try it on my system.

[digoburigo]

In my case I have a monorepo using pnpm workspaces

(NOTE: if you use pnpm wokspaces check if all apps and packages are declared in pnpm-workspace.yaml)

On root folder of project .dockerignore, with the following content

node_modules/
.vercel
.next
.env.local
.env.production
.env.dev
.env.*

dev.Dockerfile
prod.Dockerfile
Dockerfile
README.md
node_modules
npm-debug.log

[prabhjotsinghchadha]

No, It didn't work. I am also using turborepo with npm, and added the necessary files to .dockerignore.

I have the same setup, with 1.7.0 and NPM still no luck

This solution might help: #2198

@digoburigo This solved it for me, and I think the critical piece here is the exclusion of node_modules. For those with nested node_modules folder, make sure to add **/node_modules to the list.

Exec format error is likely originating from the dependencies being built for another architecture than is being provided. If for some reason your node_modules is being pulled over from your host machine and trying to be run there, it'll cause this issue.

I am able to run after downgrading docker in dockerfile
"RUN npm -g install turbo@1.6.3"

Closing as this is issues are probably related to copying node_modules into the Docker container which can result in the wrong turbo binary being installed for the OS/arch. See this esbuild doc page for a good explanation of why this causes failures for those using npm or pnpm.

If you encounter this, please verify that you aren't copying node_modules from the host and open a new issue. If you can provide a reproduction it will be beneficial as it is very likely an issue with your specific configuration.
