# To create an alpine base image:
|
||
|
|
|
||
|
|
Spin up a new VM:
|
||
|
|
- 512MB RAW Disk image (hence called alpine.img)
|
||
|
|
- Virtio Network bridge
|
||
|
|
- ISO of Alpine Virtual ed. attached
|
||
|
|
|
||
|
|
Inside the VM:
|
||
|
|
- Add the following to /etc/network/interfaces:
|
||
|
|
|
||
|
|
|
||
|
|
auto lo
|
||
|
|
iface lo inet loopback
|
||
|
|
|
||
|
|
auto eth0
|
||
|
|
iface eth0 inet dhcp
|
||
|
|
hostname alpine
|
||
|
|
|
||
|
|
- `/etc/init.d/networking restart`
|
||
|
|
- Run `setup-alpine`:
|
||
|
|
- gb
|
||
|
|
- gb
|
||
|
|
- alpine
|
||
|
|
- eth0
|
||
|
|
- dhcp
|
||
|
|
- no
|
||
|
|
- [Enter twice]
|
||
|
|
- UTC
|
||
|
|
- none
|
||
|
|
- 1
|
||
|
|
- openssh
|
||
|
|
- busybox
|
||
|
|
- sda
|
||
|
|
- sys
|
||
|
|
- y
|
||
|
|
|
||
|
|
|
||
|
|
- `passwd -d root`
|
||
|
|
- `poweroff`
|
||
|
|
|
||
|
|
Make sure the VM is stopped.
|
||
|
|
|
||
|
|
Run `virt-sysprep -a alpine.img`
|
||
|
|
|
||
|
|
Run `xz -k -verbose -T4 --best --block-size=16777216 alpine.img`
|
||
|
|
|
||
|
|
Create the index file as below. <> Shows commands to generate the required data. Replace version as needed.
|
||
|
|
|
||
|
|
```
|
||
|
|
[alpine-37]
|
||
|
|
name=Alpine 3.7
|
||
|
|
osinfo=alpine
|
||
|
|
arch=x86_64
|
||
|
|
file=alpine.img.xz
|
||
|
|
checksum=<sha512sum alpine.img.xz>
|
||
|
|
format=raw
|
||
|
|
size=<du -s alpine.img>
|
||
|
|
compressed_size=<du -s alpine.img.xz>
|
||
|
|
expand=/dev/sda3
|
||
|
|
```
|
||
|
|
|
||
|
|
Sign the index file:
|
||
|
|
`gpg --clearsign --armor index`
|
||
|
|
|
||
|
|
|
||
|
|
Upload the generated `index.asc` and `alpine.img.xz` files to a web server.
