## Hosts
|
||||
|
||||
### `build01`
|
||||
|
||||
This machine is perfect for running heavy builds.
|
||||
|
||||
* Provider: Hetzner
|
||||
* CPU: AMD Ryzen 7 1700X Eight-Core Processor
|
||||
* RAM: 64GB
|
||||
* Drives: 2 x 512 GB SATA SSD
|
||||
|
||||
### `build02`
|
||||
|
||||
This machine currently just runs r-ryantm/nixpkgs-update.
|
||||
|
||||
* Provider: Hetzner
|
||||
* CPU: AMD Ryzen 7 3700X Eight-Core Processor
|
||||
* RAM: 64GB DDR4 ECC
|
||||
* Drives: 2 x 1 TB NVME in RAID 1
|
||||
|
||||
### `build03`
|
||||
|
||||
This machine is a replacement for build01.
|
||||
|
||||
* Provider: Hetzner
|
||||
* CPU: AMD Ryzen 5 3600 6-Core Processor
|
||||
* RAM: 64GB DDR4 ECC
|
||||
* Drives: 2 x 512 GB NVME in RAID 1
|
||||
|
||||
### `build04`
|
||||
|
||||
This machine is meant as an aarch64 builder for our hydra instance running on build03.
|
||||
|
||||
* Provider: Oracle cloud
|
||||
* Instance type: [Ampere A1 Compute](https://www.oracle.com/cloud/compute/arm/)
|
||||
* CPU: 4 VCPUs on an Ampere Altra (arm64)
|
||||
* RAM: 24GB
|
||||
* Drives: 200 GB Block
|
||||
|
||||
## Deployment commands:
|
||||
|
||||
```console
|
||||
$ ./deploy
|
||||
```
|
||||
|
||||
If you want to reboot a machine, use the following command to also deploy secrets afterwards:
|
||||
|
||||
```console
|
||||
$ inv deploy --hosts build02 reboot --hosts build02
|
||||
```
|
||||
|
||||
## Install/Fix system from Hetzner recovery mode
|
||||
|
||||
1. Copy your ssh key to the recovery system so that the kexec image can re-use it.
|
||||
|
||||
``` console
|
||||
yourmachine> ssh-copy-id root@build0X.nix-community.org
|
||||
```
|
||||
|
||||
2. Download and boot into kexec-image:
|
||||
|
||||
``` console
|
||||
$ curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-kexec-installer-x86_64-linux.tar.gz | tar -xzf- -C /root
|
||||
$ /root/kexec/run
|
||||
```
|
||||
|
||||
3. Format and/or mount all filesystems to /mnt:
|
||||
|
||||
```console
|
||||
$ inv format-disks --hosts buildXX --disks /dev/nvme0n1,/dev/nvme1n1
|
||||
```
|
||||
|
||||
4. Setup secrets
|
||||
|
||||
```console
|
||||
$ inv setup-secret --hosts buildXX
|
||||
```
|
||||
|
||||
5. Generate configuration and download to the repo
|
||||
|
||||
```console
|
||||
$ nixos-generate-config --root /tmp
|
||||
# optional, in most cases one can import roles/hetzner/amd.nix
|
||||
$ scp buildXX.nix-community.org:/tmp/etc/nixos/hardware-configuration.nix buildXX/hardware-configuration.nix
|
||||
```
|
||||
|
||||
6. Build and install
|
||||
|
||||
```console
|
||||
$ inv install-nixos --hosts buildXX
|
||||
```
|
||||
|
||||
### Debug VM
|
||||
|
||||
You can start a vm from the rescue system in order to debug the boot:
|
||||
|
||||
```console
|
||||
$ nix-shell -p qemu_kvm --run 'qemu-kvm -m 10G -hda /dev/sda -hdb /dev/sdb -curses -cpu host -enable-kvm'
|
||||
```
