Launch_Alpine_Linux_3.3.x_on_AWS.md

Create a local VM of Alpine Linux, eg: https://gist.github.com/kennwhite/959d47a77070d365ad60

  • On your workstation open a terminal and create a new ssh keypair:

    ssh-keygen -t rsa -b 4096 -C "[email protected]"

    • Set a meaningful keypair base file name when prompted, eg: alpine-test

  • On the Alpine VM, login as root

    • If you've not yet already done it, set a proper, strong root password
    • Add the public key (e.g. alpine-test.pub) to the Alpine /root/.ssh/authorized_keys file

  • Launch a new EC2 Amazon Linux micro instance: EBS-backed, PV (I haven't tested HVM yet), 2GB EBS root is fine. At the time of this writing, the AMI is: amzn-ami-minimal-pv-2015.09.2.x86_64-ebs (ami-b0f4deda)

  • Create a new 1GB EBS volume (make sure to set the same Availability Zone), attach it as: /dev/xvdf in the control pannel to that instance

  • On the new EC2 instance, login as ec2-user

    • Sudo root and create a stub boot volume for Alpine:
    sudo su -
cd /root
mke2fs -t ext4 /dev/xvdf
# Note: Do not partition it - just format the whole volume
curl -sLO http://wiki.alpinelinux.org/cgi-bin/dl.cgi/v3.3/releases/x86_64/alpine-3.3.1-x86_64.iso
openssl dgst -sha256 alpine-3.3.1-x86_64.iso 
# Compare this to the current hash:
#  0c6be63cbeab562e805b0e337edbc363e8f1291f67e6f9cb0f2daf6695587157  alpine-3.3.1-x86_64.iso

mkdir target
mkdir source
mount /dev/xvdf target
mount -o loop alpine-3.3.1-x86_64.iso source
cp -av source/boot target
cp -av source/apks target
umount source
mkdir -p target/boot/grub

cat - >target/boot/grub/grub.conf <<EOF

cat /root/target/boot/grub/grub.conf 
cd target/boot/grub
ln -sf ./grub.conf ./menu.lst

  • On the Alpine Linux VM, as root force server-side keys to be regenerated on boot, then use the Alpine lbu local backup tool to bundle bootstrap files:

    rm /etc/ssh/*key* 
lbu include root/.ssh
lbu package amazon.apkovl.tar.gz
    • Copy the amazon.apkovl.tar.gz file from the Alpine VM to the EC2 instance /root/target
      • (This is a total hack, but works in a pinch if you don't want to move keys)
    base64 amazon.apkovl.tar.gz > amazon.apkovl.tar.gz.b64
    md5sum amazon.apkovl.tar.gz.b64
    cat amazon.apkovl.tar.gz.b64
  • Copy base64 contents (about 7K) to the paste buffer
  • On the EC2 instance:
    echo "[paste]" | base64 -id  > amazon.apkovl.tar.gz
    md5sum amazon.apkovl.tar.gz
    # (Assuming checksums match)
    tar -xzvf amazon.apkovl.tar.gz -C /root/target
  • On the EC2 instance, unmount the filesystem, then the volume umount /root/target
  • In the EBS Volume console, detach the new EBS volume (tag the volume name as "Alpine root" for sanity)
  • Stop the EC2 instance (don't temrinate), then detach the original root volume (maybe tag volume name as "Old root")
  • Attach the EBS volume as the root volume: /dev/sda1 (*note must be /dev/sda1 not /dev/sda)
  • Startup the instance
  • If you have trouble, check the ec2 console boot log from the Instance/Actions/Instance Settings menu
  • Getting stuck here see attached ec2 console log, showing startup, but not networking/dhcp/sshd

Hello,
I tried your tutorial step-by-step but it does not work.
At the end you state

Attach the EBS volume as the root volume: /dev/sda1 (note must be /dev/sda1 *not /dev/sda)

but that is not possible.
If I enter /dev/sd[something] I cannot start the instance as the aws-console tells me that the instance does not have a root-volume.
If I enter /dev/xvda (/dev/xvda1 is not possible) the instance does start but goes offline shortly after.
Since nothing is written to the log (InstanceSettings/SystemLog) I assume the boot loader has a problem.

I'd appreciate your help.
Thank you!

Same thing here, trying with 3.4.0. No log at all, so I suspect the bootloader. Can you clarify if you're using the standard image or the virt image?

To get this to boot on HVM there are a couple of tweaks needed. Firstly you need a partition so use fdisk to create /dev/xvdf1 and then format that as per the guide. Also you actually need to install grub to the MBR. Edit device.map so that it looks like this:

cat /home/ec2-user/target/boot/grub/device.map
(hd0)   /dev/xvdf

Modify grub.conf so that it has root (hd0,0) not root (hd0)

Finally install the bootloader:

grub-install --root-directory=/home/ec2-user/target /dev/xvdf

Hello guys,
I've tried to follow your guide but failed to connect to my EC2 instance loaded from Alpine EBS volume.

I was wondering if you could guide me to the right direction.

Hello @kennwhite , Thanks for sharing your instructions !

Btw, I'm on the same state at your. It appears that the sequence we have there is only the initramfs one.
You can search for the log outputs, coming from the AWS console, inside the "init" shell script which is on the initramfs.

(Uncompress the initramfs as this: mkdir temp && cd temp && gunzip -c /root/target/boot/initramfs-grsec | cpio -i )

I'll try to see how to deploy the tar.gz archive inside the initramfs and then rebuild it, OR following https://wiki.alpinelinux.org/wiki/DIY_Fully_working_Alpine_Linux_for_Allwinner_and_Other_ARM_SOCs#Creating_Initramfs_File and https://wiki.alpinelinux.org/wiki/Alpine_Source_Map_by_boot_sequence , how the chain the next steps for the boot sequence

@kennwhite, thanks for the writeup. The entire setup works and I've been able to create an AMI and launch an instance. The problem however is that I'm unable to login! I have my authorized_keys setup but I just get permission denied!
