Docker in Slackware 14.2

Posted by in Slackware

First, install sbopkg: https://sbopkg.org/
Make sure you have the (standard 14.2) gcc-go package installed.
Select preferred editor before starting sbopkg (default is vi):

> export EDITOR=nano
> sbopkg

From sbopkg, download, build and install tini and Go:

tini
google-go-lang

After google-go-lang is installed, quit sbopkg and make sure to add the path to the new go-binary in ~/.bashrc (check the go version):
PATH=$PATH:/usr/lib64/go1.16.3/go/bin
Logout and login from the terminal session or run:

> . ~/.bashrc

Start sbopkg again and build these packages in the given order:

docker-proxy
libseccomp
runc
containerd
docker
docker-cli
docker-compose

You have to edit the .Slackbuilds for all the packages in bold above before building them and add “GO111MODULE=auto \” before the row that contains the GOPATH row (Select “Custom/Edit Slackbuild” from the package menu in sbopkg).

Slackbuild:
.
.
.
GO111MODULE=auto \
GOPATH=$TMP/$SRCNAM-$VERSION/build

Good luck! If everything worked as it should, let’s try Docker out and create a minimal Dockerfile:

# Text file named Dockerfile
FROM busybox
ADD https://github.com/just-containers/s6-overlay/releases/download/v1.21.8.0/s6-overlay-amd64.tar.gz /tmp/
RUN gunzip -c /tmp/s6-overlay-amd64.tar.gz | tar -xf - -C /
ENTRYPOINT ["/init"]

> chmod +x /etc/rc.d/rc.docker
> /etc/rc.d/rc.docker start
> docker build -t s6demo .
> docker run -ti s6demo /bin/sh

Or why not try to run Slackware in Docker?
(from http://www.slackware.com/~vbatts/docker/)

docker run -i -t vbatts/slackware bash

Create a Slackware kernel (initrd) for Hyper-V

Posted by in Lagom

If you are installing Slackware, after setup is done and before reboot, first chroot into the root partition:
# mount -t ext4 /dev/sda1 /mnt
# mount -o bind /proc /mnt/proc
# mount -o bind /dev /mnt/dev
# mount -o bind /sys /mnt/sys
# chroot /mnt 

# mkinitrd -c -f ext4 -r /dev/sda1 -m hv_vmbus:hv_storvsc:mbcache:jbd2:ext4 -u -o /boot/initrd.gz -k 4.4.xxx

-r = boot partition
-k = kernel version

edit /etc/lilo.conf (or grub, elilo.conf etc) to match new initrd and generic kernel:

# nano -w /etc/lilo.conf

image = /boot/vmlinuz-generic-4.4.xxx
   append = "elevator=noop"
   initrd = /boot/initrd.gz
   root = /dev/sda1
   label = hyperv
   read-only

# lilo
