Typescript docker build pass but fail to start

[bright-coder]

Hey, what operating system are you running?

Could you also give some more context regarding how you set up the app? Did you create it as part of a npm workspace, or is it standalone?

docker-inspect.json
This happens on Windows 11 with standalone setup using encore create app on 1.43.2. The encore library path looks strange in the docker output layer, although this may be a red herring.

@crorvigvp yeah that it’s. How to fix it ?

[lpkobamn]

I ran into a similar problem and it's crazy that no one fixed it for a few weeks!

I made an app with the command

encore app create --example=ts/uptime

Then I tried to build with the command encore

build docker b2b --skip-config

I tried to run with the command

docker run -e PORT=8081 -p 8081:8081 b2b

but there was an error:

C:\Windows\System32>docker run -e PORT=8081 -p 8081:8081 b2b
node:internal/modules/esm/resolve:857
  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

Node.js v23.1.0

Encore version is v1.43.12, and I'm on Windows 10 Pro 22H2 19045.2604 with service pack 120.2212.4190.

Can anyone help?

[eandre]

We're going to look into this in the near future. It appears to be due to how symlinks work on windows. Until then you can build Docker images using WSL or a macOS/Linux machine.

Not better on linux
I don't understand

/artifacts/0/node_modules/encore.dev/internal/runtime/mod.ts:8
export const RT = new Runtime({
                  ^


Error: failed to initialize runtime: unable to parse runtime config

@lpkobamn you need to provide a infra config, see https://encore.dev/docs/ts/self-host/configure-infra

[fredr]

If you update to encore v1.45.1 it should now work to run on windows, try it out with encore version update

There are a few edge cases still on windows that we are hunting down, but this particular issue should now be solved. Let me know how it works
