Hi All,
I am currently facing with a relabel config issue.
I would like to drop all namespaces which not contain the word NAMESPACE1,
For this aim I try with the following regex expression :
relabel_configs:
- source_labels: [__meta_kubernetes_namespace]
regex: '^((?!NAMESPACE1).)*$'
action: drop
But I am facing with a syntax error (invalid orunsupported Perl syntax:
`(?!` )
level=error ts=2020-03-24T10:07:01.722Z caller=main.go:740 err="error
loading config from \"/etc/prometheus/prometheus.yml\": couldn't load
configuration (--config.file=\"/etc/prometheus/prometheus.yml\"): parsing
YAML file /etc/prometheus/prometheus.yml: error parsing regexp: invalid or
unsupported Perl syntax: `(?!`"
Any idea?
Thanks
Nabil L.
