Cache builder as startup service

[delucca]

Hi!

I'm trying to add cache_builder as a startup service on my computer, but I get the following error on systemctl status:

● cache-builder.service - Cache Builder for Kubectl-FZF Service
     Loaded: loaded (/etc/systemd/system/cache-builder.service; disabled; vendor preset: disabled)

Any idea on how to fix it? It apppears that it is trying to use a different user upon startup. Also, when I run this as a normal command after startup, it works as expected.

The log indicated that systemctl managed cache builder cannot find the right kubeconfig (which located at ~/.kube/config).

cache_builder support setting kubeconfig by flag

https://github.com/bonnefoa/kubectl-fzf/blob/af8ac639c501b274aecb18bbddb709f433ef4a30/cmd/cache_builder/main.go#L56-L60

So just set the absolute path to the kubeconfig file as param will be fine. Make sure that file's permission is correct and readable.

There's an example on how to use kubectl-fzf as a systemd service now https://github.com/bonnefoa/kubectl-fzf#install-kubectl-fzf-server-as-a-systemd-service kubectl-fzf now only relies on KUBECONFIG to look for the correct kubeconfig file.
