s6-mkfifo Error #161

Open AndrewSkelton opened 4 years ago

AndrewSkelton commented 4 years ago

Hi,

After slimming my image, when I try to start it up, I get the following error:

s6-mkfifo: fatal: unable to mkfifo /var/run/s6/services/s6-fdholderd/supervise/control: No such file or directory

Any suggestions on a way to resolve this?

To reproduce:

docker pull bioconductor/bioconductor_docker:devel
./docker-slim build bioconductor/bioconductor_docker:devel
docker run \                                                                                            
        -e PASSWORD=bioc \
        -p 8787:8787 \
        bioconductor/bioconductor_docker.slim
# s6-mkfifo: fatal: unable to mkfifo /var/run/s6/services/s6-fdholderd/supervise/control: No such file or directory

adding a few links for context...

The container image info:

https://hub.docker.com/r/bioconductor/bioconductor_docker
https://github.com/Bioconductor/bioconductor_docker
https://github.com/Bioconductor/bioconductor_docker/blob/master/Dockerfile - the Dockerfile for the image

Looks like there's a lot of stuff in that image and it's more like a base image and an IDE rolled into one :-) This means that they'll be lots of extra packages there intentionally because it's meant to be used as a tool to build new applications...

The error itself is probably related to the s6-overlay init system and how it's designed. Need to investigate more...

Interestingly, (and something I should have included in the original post) is that /var/run/s6/services/s6-fdholderd/supervise/control doesn't seem to exist when starting the un-slimmed image with bash, but could be something that is created when starting the web service to serve the IDE.

This image is built from rocker/rstudio:4.0.2, which stems from debian:buster. Essentially contains the following:

Base language R
IDE RStudio which is served through a web interface (port 8787)
Base set of packages (Bioconductor)

Happy to test any hypotheses, as the slimming procedure drastically reduces the size burden of this image, and makes it much more workable!
