Image with pre-installed compiletc

I made a variant where "compiletc" is pre-installed:

FROM tinycore:9.0-x86_64

RUN tce-load -wic compiletc \
    && rm -rf /tmp/tce/optional/*

It comes in handy when cross-compiling for TCL.

Maybe it is something that could be provided ?

Saves time (and bandwidth) for new containers.

Document minimum kernel requirements

Seems like glibc now requires newer kernel:

$ docker run -it tatsushid/tinycore:9.0-x86_64
/ $ exit
$ docker run -it tatsushid/tinycore:10.0-x86_64

FATAL: kernel too old

Tiny Core Linux 10.0 now requires 4.8 to run...

8.x: glibc-2.24, --enable-kernel=3.16.6
9.x: glibc-2.26, --enable-kernel=4.2.9
10.x: glibc-2.28, --enable-kernel=4.8.17

Not so much that can be done about this inside the container though (except for rebuilding glibc ?)

But it means e.g. that you can no longer run it on Ubuntu 16.04, need to upgrade to Ubuntu 18.04

Error with liblzma during TCZ installation

Hello,

When I try to install a software I have an error:

Perhaps you have an idea on this message:-).

Make a default "latest" tag?

It would be useful when people want a quick test run.

Avoid mount also for regular install ?

Currently the mount command is avoided for the copy only, but not for the regular install command.

This means that it fails, when not running --privileged: mount: permission denied (are you root?)

If you use the same workaround there as well, that would allow running the usual tce-load -wi:

This means that it would work (similar to regular Tiny Core Linux) out-of-the-box...

User can mount a docker volume on /tmp/tcloop, for a more similar experience.

Can't run image in the background.

When trying to start the machine via docker run -d 533fceaa79a9 the image outputs the docker ID as normal, but when I try to use docker attach <outputid> docker says there are no running containers. I do docker ps -l and it outputs:

 CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES

I'm new to docker and have read the help documentation but am still lost. Is this image not built to run in the background?

Invalid squashfs-tools.tar.gz for 8.0 images

The squashfs-tools.tar.gz tarball used in the 8.0 image is invalid, and as such the file is just copied to the image, rather than being unpacked.

Notice the tar.gz file on the 5th line from the bottom.

There are no issues with the file in 7.2

Fails to install software inside the image

I'd like to install some tools inside the container started based on this image but I'm failing at it.

The software can be downloaded and installed but fails to be loaded into the current image.

tc@abd4d07279b1:~$ tce-load -il gcc.tcz
mount: permission denied (are you root?)
tc@abd4d07279b1:~$ sudo tce-load -il gcc.tcz
Don't run this as root.

Any thoughts?

TinyCore 11.x released

Hi @tatsushid, I was wondering if you have plans to publish a release for TinyCore 11.x. I can make a pull request with the changes if you're too busy.

Thanks.
