timezone by ignition

[Maarten Dekker]

Hi All,

Probably my question is either deadsimple or I overlooked something, so lets give it a shot here.

How can I set the timezone with ignition?

Its a typical thing you usually do only once, but I could not find a good example for ignition other than doing it as a one-shot, but I am not sure if that should be the right way to go.

Please advise :-)

Can you create a service like this?

If you don't want it to run again, a ConditionFirstBoot=yes on the
service should prevent that.

Thanks.

Hi David,

Thanks for your reply.

You are pointing towards a cloud-config recipe.

The thing is the initial system setup is being done by iginition and I would like to keep it like that, especially now CoreOS is having a bigger focus on ignition.

Yes, I meant: Are you able to write that example service file with Ignition?

Thanks.

Now that the Ignition 2.1.0 specification allows for symlinks, you can
use something like the following Container Linux Config:

storage:
links:
- path: /etc/localtime
target: /usr/share/zoneinfo/America/Los_Angeles
filesystem: root

I haven't actually tested this, but it would be great to know if it
solves your issue.

There's a problem with that config in that `/etc/localtime` is a preexisting file, so the symlink creation will fail. I actually made a PR today to fix that: https://github.com/coreos/ignition/pull/494
