bad interpreter: No such file or directory about docker-simple-mail-forwarder HOT 7 CLOSED

Hi all,

I'm terribly sorry for causing this problem with my mistake. I have sent a fix and hope this issue has been solved.

Please try the v1.2 that I have just re-published on the docker hub, which I have tested, and the /bin/execlineb should be OK now. (the tag with 1.3 was deleted)

Please feel free to let me know if there are still any problems. ( and PR is welcome )

Explanation

When I tried to build a multi-platform docker image with buildx (#76), I do not know how to select the s6-overlay with the right platform version in the Dockerfile with different platforms.

That's the time when I saw a nobin version in the s6-overlay release, which I thought it's platform-independent and I can just use it.

However, the nobin version is just the scripts without any binary, which will not be able to work, and that's the reason that makes this trouble for us.

See: The "nobin" variant is strictly the scripts of the s6-overlay, with absolutely no binaries.

Likewise. My cluster pulled the v1.2 image automatically, which would not even start.

I didn't have monitoring on the service, so my company's emails were broken for 2 days before I noticed.

I tried to downgrade to 1.1, but this old version appears to not have authentication support. If you exec -it the container and cat the entrypoint.sh, there is no reference to SMF_RELAYAUTH. Has the working version of this tool disappeared from docker? It seems like latest got overwritten, and now there is no working image.

I ended up checking out sha f50ed9693194ebe65d816825f1951921b792ec50 (from a few months ago), building it, and pushing to inzania/email:latest. This version supports SMF_RELAYAUTH and is working just like it used to be before the cluster update.

Hello I got the same issue...

I tracked down this issue to the update of the S6 overlay by this 08daf27.

❯ dco -f simple-mail-forwarder.yml run --rm --entrypoint /bin/bash mail
bash-5.0# ls /init
/init
bash-5.0# vi /init
bash-5.0# ls /bin/execlineb
ls: cannot access '/bin/execlineb': No such file or directory
bash-5.0# find / -name "execlineb"
/usr/bin/execlineb
bash-5.0# 

Every S6 script use /bin/execlineb as shell bang.

We need to split the overlay extraction as described on their page https://github.com/just-containers/s6-overlay#bin-and-sbin-are-symlinks .
