Jenkins, InfluxDB and Grafana

Today an basic introduction to Jenkins, InfluxDB and Grafana. Docker is used to save some time. Okay,… let’s start.


# create project and change directory
$ mkdir ~/Projects/JIG/influxdb && cd ~/Projects/JIG/

# download official jenkins image (latest)
$ docker pull jenkins

# download official influxdb image (latest)
$ docker pull influxdb

# download official grafana image (latest)
$ docker pull grafana/grafana

# list docker images
$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

Jenkins preparation

# start Jenkins
$ docker run --name jenkins -p 8080:8080 jenkins

# copy password from cli

Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:


Now open your favorite browser with URL http://localhost:8080 and unlook Jenkins with following steps.

unlook jenkins

  1. unlook with password from cli
  2. install suggested plugins
  3. create your admin user
  4. start using jenkins

Next, the InfluxDB plug-in must be installed.

influxdb plugin jenkins

InfluxDB preparation

# start InfluxDB
$ docker run --name influxdb -p 8086:8086 -v $PWD/influxdb:/var/lib/influxdb influxdb

# check current configuration (optional)
$ docker exec -i influxdb influxd config

# create new user
$ curl -G http://localhost:8086/query --data-urlencode "q=CREATE USER jenkins WITH PASSWORD 'password123' WITH ALL PRIVILEGES"

# create database for jenkins
$ curl -G http://localhost:8086/query -u jenkins:password123 --data-urlencode "q=CREATE DATABASE jenkins_db"

# show users (optional)
$ curl -G http://localhost:8086/query -u jenkins:password123 --data-urlencode "q=SHOW USERS"

# show databases (optional)
$ curl -G http://localhost:8086/query -u jenkins:password123 --data-urlencode "q=SHOW DATABASES"

# show measurements
$ curl -G http://localhost:8086/query -u jenkins:password123 --data-urlencode "db=jenkins_db" --data-urlencode "q=SHOW MEASUREMENTS"

Connect Jenkins with InfluxDB

# start jenkins container (if stopped)
$ docker start jenkins

# show ip of influxdb container
$ docker inspect --format '{{ .NetworkSettings.IPAddress }}' influxdb

Add new InfluxDB target on Jenkins

jenkins influxdb settings

Save and create a new freestyle job. For example with following configuration.

jenkins job influxdb

When you are done, run the job.

# show measurements
$ curl -G http://localhost:8086/query -u jenkins:password123 --data-urlencode "db=jenkins_db" --data-urlencode "q=SHOW MEASUREMENTS"

# run select statement (optional)
$ curl -G http://localhost:8086/query -u jenkins:password123 --data-urlencode "db=jenkins_db" --data-urlencode "q=SELECT * FROM jenkins_data"

Add Grafana

# start containers (if stopped)
$ docker start influxdb && docker start jenkins

# run grafana container
$ docker run --name grafana -i -p 3000:3000 grafana/grafana

Open you browser with URL http://localhost:3000, login with credentials (admin/admin) and add a new InfluxDB data source.

grafana data source

From now on, you can create and share dashboards in Grafana, which shows all Jenkins metrics.
