[FATAL tini (7)] exec bash failed: No such file or directory

[alifiroozi80]

Hello guys,

I have a Dockerfile which uses the tini. Everything is okay if I build the image as usual (docker build -t test:1.0.0 .).

Now I'm using slim to shrink the image size.

This method will delete the dependencies of the tini so, as the docs say:

Tini has very few dependencies (it only depends on libc), but if your container fails to start, you might want to consider using the statically-built version instead

I change the Dockerfile from:

[...]
ENV TINI_VERSION v0.19.0
ADD https://github.com/krallin/tini/releases/download/${TINI_VERSION}/tini /tini
RUN chmod +x /tini
[...]

To:

[...]
ENV TINI_VERSION v0.19.0
ADD https://github.com/krallin/tini/releases/download/${TINI_VERSION}/tini-static /tini
RUN chmod +x /tini
[...]

So it should run fine.

---

But after installation, something needs to be fixed!

E.g.

$ docker run --rm -it 2b1ea6590896 bash
[FATAL tini (7)] exec bash failed: No such file or directory

P.S.: I know the bash is installed on my container. The same command works fine if I don't shrink the image.

Bash might not be on your PATH, or it might not exist at all in your image.

Tini is working fine here, that’s not a library problem, since it gets as far as a executing your binary.

Sounds a lot like “shrinking” your image deleted bash.

Do bear in mind that Tini itself does depend on bash. If it’s running bash that’s because you’re asking it to do so.

As a next step, I would suggest double checking what actually is in your image

Hello @krallin Thank you for your quick response. You were right! After I added the --include-shell flag to the slim during the shrinking, it is now working, and it's not tini fault! Thank you, sir, for this excellent tool
