Description
Describe the bug
Algo fails on Hetzner’s USA locations when using thecx11 server size, which is the default included in Algo’s config.cfg file. The Hetzner Cloud API responds with:
error during placement (resource_unavailable)
This is not necessarily a bug in Algo, since the same error occurs when trying to create a cx11 server using Hetzner's CLI tools.
I asked Hetzner why this error occurs, and they replied:
CX-Servers with INTEL CPU are not offered in our US-Locations.
So, the fix is to update Algo's config.cfg file to use server cpx11 instead of cx11 (cpx11 is the smallest server size that is available in all Hetzner locations; it has 2 vCPUs instead of 1, and costs €3.85 instead of €3.29 per month):
hetzner:
server_type: cpx11
image: ubuntu-20.04To Reproduce
Steps to reproduce the behavior:
- Run
./algo - Select Provider =
Hetzner Cloud. - Select a region of
ashorhil. - Ansible fails with the error:
fatal: [localhost]: FAILED! => {"changed": false, "msg": "error during placement"}.
Expected behavior
Algo's default config should work for all providers and all locations.
