3 [Prometheus](https://prometheus.io/), a [Cloud Native Computing Foundation](https://cncf.io/) project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.
8 $ helm install stable/prometheus
13 This chart bootstraps a [Prometheus](https://prometheus.io/) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
17 - Kubernetes 1.3+ with Beta APIs enabled
19 ## Installing the Chart
21 To install the chart with the release name `my-release`:
24 $ helm install --name my-release stable/prometheus
27 The command deploys Prometheus on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
29 > **Tip**: List all releases using `helm list`
31 ## Uninstalling the Chart
33 To uninstall/delete the `my-release` deployment:
36 $ helm delete my-release
39 The command removes all the Kubernetes components associated with the chart and deletes the release.
43 Prometheus version 2.x has made changes to alertmanager, storage and recording rules. Check out the migration guide [here](https://prometheus.io/docs/prometheus/2.0/migration/)
45 Users of this chart will need to update their alerting rules to the new format before they can upgrade.
47 ## Upgrading from previous chart versions.
49 Version 9.0 adds a new option to enable or disable the Prometheus Server.
50 This supports the use case of running a Prometheus server in one k8s cluster and scraping exporters in another cluster while using the same chart for each deployment.
51 To install the server `server.enabled` must be set to `true`.
53 As of version 5.0, this chart uses Prometheus 2.x. This version of prometheus introduces a new data format and is not compatible with prometheus 1.x. It is recommended to install this as a new release, as updating existing releases will not work. See the [prometheus docs](https://prometheus.io/docs/prometheus/latest/migration/#storage) for instructions on retaining your old data.
57 Assuming you have an existing release of the prometheus chart, named `prometheus-old`. In order to update to prometheus 2.x while keeping your old data do the following:
59 1. Update the `prometheus-old` release. Disable scraping on every component besides the prometheus server, similar to the configuration below:
74 storage.local.retention: 720h
81 1. Deploy a new release of the chart with version 5.0+ using prometheus 2.x. In the values.yaml set the scrape config as usual, and also add the `prometheus-old` instance as a remote-read target.
87 - url: http://prometheus-old/api/v1/read
91 Old data will be available when you query the new prometheus instance.
93 ## Scraping Pod Metrics via Annotations
95 This chart uses a default configuration that causes prometheus
96 to scrape a variety of kubernetes resource types, provided they have the correct annotations.
97 In this section we describe how to configure pods to be scraped;
98 for information on how other resource types can be scraped you can
99 do a `helm template` to get the kubernetes resource definitions,
100 and then reference the prometheus configuration in the ConfigMap against the prometheus documentation
101 for [relabel_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config)
102 and [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config).
104 In order to get prometheus to scrape pods, you must add annotations to the the pods as below:
109 prometheus.io/scrape: "true"
110 prometheus.io/path: /metrics
111 prometheus.io/port: "8080"
116 You should adjust `prometheus.io/path` based on the URL that your pod serves metrics from.
117 `prometheus.io/port` should be set to the port that your pod serves metrics from.
118 Note that the values for `prometheus.io/scrape` and `prometheus.io/port` must be
119 enclosed in double quotes.

383 Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
386 $ helm install stable/prometheus --name my-release \
387 --set server.terminationGracePeriodSeconds=360
390 Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
393 $ helm install stable/prometheus --name my-release -f values.yaml
396 > **Tip**: You can use the default [values.yaml](values.yaml)
398 Note that you have multiple yaml files. This is particularly useful when you have alerts belonging to multiple services in the cluster. For example,
404 # service1-alert.yaml
411 # service2-alert.yaml
420 $ helm install stable/prometheus --name my-release -f values.yaml -f service1-alert.yaml -f service2-alert.yaml
423 ### RBAC Configuration
424 Roles and RoleBindings resources will be created automatically for `server` service.
426 To manually setup RBAC you need to set the parameter `rbac.create=false` and specify the service account to be used for each service by setting the parameters: `serviceAccounts.{{ component }}.create` to `false` and `serviceAccounts.{{ component }}.name` to the name of a pre-existing service account.
428 > **Tip**: You can refer to the default `*-clusterrole.yaml` and `*-clusterrolebinding.yaml` files in [templates](templates/) to customize your own.
431 AlertManager is configured through [alertmanager.yml](https://prometheus.io/docs/alerting/configuration/). This file (and any others listed in `alertmanagerFiles`) will be mounted into the `alertmanager` pod.
433 Prometheus is configured through [prometheus.yml](https://prometheus.io/docs/operating/configuration/). This file (and any others listed in `serverFiles`) will be mounted into the `server` pod.
436 If your cluster allows automatic creation/retrieval of TLS certificates (e.g. [kube-lego](https://github.com/jetstack/kube-lego)), please refer to the documentation for that mechanism.
438 To manually configure TLS, first create/retrieve a key & certificate pair for the address(es) you wish to protect. Then create a TLS secret in the namespace:
441 kubectl create secret tls prometheus-server-tls --cert=path/to/tls.cert --key=path/to/tls.key
444 Include the secret's name, along with the desired hostnames, in the alertmanager/server Ingress TLS section of your custom `values.yaml` file:
449 ## If true, Prometheus server Ingress will be created
453 ## Prometheus server Ingress hostnames
454 ## Must be provided if Ingress is enabled
457 - prometheus.domain.com
459 ## Prometheus server Ingress TLS configuration
460 ## Secrets must be manually created in the namespace
463 - secretName: prometheus-server-tls
465 - prometheus.domain.com
470 Enabling Network Policy for Prometheus will secure connections to Alert Manager
471 and Kube State Metrics by only accepting connections from Prometheus Server.
472 All inbound connections to Prometheus Server are still allowed.
474 To enable network policy for Prometheus, install a networking plugin that
475 implements the Kubernetes NetworkPolicy spec, and set `networkPolicy.enabled` to true.
477 If NetworkPolicy is enabled for Prometheus' scrape targets, you may also need
478 to manually create a networkpolicy which allows it.
