RUNTIME ERROR: couldn't open import "kube-prometheus/main.libsonnet": no match locally or in the Jsonnet library path

[rupang790]

What happened? I was trying to install kube-prometheus with customizing about Thanos-sidecar. I followed docs https://github.com/prometheus-operator/kube-prometheus#customizing-kube-prometheus but there was some error when I execute build.sh with jsonnet.

I already searched closed issue about same as my error, but I could not find solutions. Do you have any idea about this to solve?

Did you expect to see some different?

How to reproduce it (as minimally and precisely as possible):

$ mkdir my-kube-prometheus
$ cd my-kube-prometheus

$ jb init
$ jb install github.com/prometheus-operator/kube-prometheus/jsonnet/[email protected]
$ wget https://raw.githubusercontent.com/prometheus-operator/kube-prometheus/release-0.7/build.sh -O build.sh
$ jb update

$ go get github.com/brancz/gojsontoyaml

Then I copied Thanos-sidecar.jsonnet from this git.

local kp =
  (import 'kube-prometheus/main.libsonnet') +
  {
    values+:: {
      common+: {
        namespace: 'monitoring',
      },
      prometheus+: {
        thanos: {
          version: '0.19.0',
          image: 'quay.io/thanos/thanos:v0.19.0',
          objectStorageConfig: {
            key: 'thanos.yaml',  // How the file inside the secret is called
            name: 'thanos-objectstorage',  // This is the name of your Kubernetes secret with the config
          },
        },
      },
    },
  };

{ ['setup/0namespace-' + name]: kp.kubePrometheus[name] for name in std.objectFields(kp.kubePrometheus) } +
{
  ['setup/prometheus-operator-' + name]: kp.prometheusOperator[name]
  for name in std.filter((function(name) name != 'serviceMonitor'), std.objectFields(kp.prometheusOperator))
} +
// serviceMonitor is separated so that it can be created after the CRDs are ready
{ 'prometheus-operator-serviceMonitor': kp.prometheusOperator.serviceMonitor } +
{ ['node-exporter-' + name]: kp.nodeExporter[name] for name in std.objectFields(kp.nodeExporter) } +
{ ['kube-state-metrics-' + name]: kp.kubeStateMetrics[name] for name in std.objectFields(kp.kubeStateMetrics) } +
{ ['alertmanager-' + name]: kp.alertmanager[name] for name in std.objectFields(kp.alertmanager) } +
{ ['prometheus-' + name]: kp.prometheus[name] for name in std.objectFields(kp.prometheus) } +
{ ['prometheus-adapter-' + name]: kp.prometheusAdapter[name] for name in std.objectFields(kp.prometheusAdapter) } +
{ ['grafana-' + name]: kp.grafana[name] for name in std.objectFields(kp.grafana) }

After that, execute ./build.sh thanos-sidecar.jsonnet

thanos-sidecar.libsonnet is an example on release-0.8 branch and there is no such example for release-0.7. Those branches are incompatible with each other and we have migration guide in https://github.com/prometheus-operator/kube-prometheus/blob/main/docs/migration-guide.md.

couldn't open import "kube-prometheus/main.libsonnet": no match locally or in the Jsonnet library path

release-0.7 do not have main.libsonnet. On that branch similar file is called kube-prometheus.libsonnet.

[rupang790]

@paulfantom , I will check again my branch and try again for it. Thanks for mentions.

I faced the same error using your examples https://github.com/prometheus-operator/kube-prometheus/blob/main/examples/additional-namespaces.jsonnet after executing ./build.sh additional-namespaces.jsonnet I got RUNTIME ERROR: couldn't open import "kube-prometheus/main.libsonnet": no match locally or in the Jsonnet library path

Also I have tried import "kube-prometheus.libsonnet" and import "kube-prometheus/kube-prometheus.libsonnet". But error still occurs. What's the solution?

[dgrisonnet]

It might be because you haven't downloaded the jsonnet dependencies. Could you try running make vendor before building the manifests?

Following the installation documentation should also help you: https://github.com/prometheus-operator/kube-prometheus#installing. Note that it is required to do the installation before compiling.

[Epimetheus84]

@dgrisonnet, Yes, I dowloaded dependencies using jb init & jb install github.com/prometheus-operator/kube-prometheus/jsonnet/[email protected] I have this vendor structure

make vendor says "make: Nothing to be done for 'vendor'."

Since your bug seems different than the original one reported in this issue, would you mind opening another bug?
