Install InfluxDB Inside Docker Container in Linux

InfluxDB is a time series database. It is often used to store data gathered from Internet of Things (IoT) devices. InfluxDB is an open-source project available under the MIT license.

This tutorial explains how to install InfluxDB inside a Docker container in the Linux. Commands have been tested on Ubuntu.

Prepare environment

Make sure you have installed Docker in your system. If you are using Ubuntu, installation instructions can be found in the post.

Install InfluxDB

• Host network

Run the following command to create a container for InfluxDB that uses host network:

docker run -d --name=influxdb --restart=always --network=host \
    -v /opt/influxdb/data:/var/lib/influxdb2 \
    -v /opt/influxdb/config:/etc/influxdb2 \
    -e DOCKER_INFLUXDB_INIT_MODE=setup \
    -e DOCKER_INFLUXDB_INIT_USERNAME=admin \
    -e DOCKER_INFLUXDB_INIT_PASSWORD=password123 \
    -e DOCKER_INFLUXDB_INIT_ORG=my-org \
    -e DOCKER_INFLUXDB_INIT_BUCKET=my-bucket \
    influxdb

• User-defined bridge network

User-defined bridge network can be used for listening on different port. By default, InfluxDB service is listening on port 8086. It can be changed with -p option.

docker network create app-net

docker run -d --name=influxdb --restart=always --network=app-net \
    -p 8080:8086 \
    -v /opt/influxdb/data:/var/lib/influxdb2 \
    -v /opt/influxdb/config:/etc/influxdb2 \
    -e DOCKER_INFLUXDB_INIT_MODE=setup \
    -e DOCKER_INFLUXDB_INIT_USERNAME=admin \
    -e DOCKER_INFLUXDB_INIT_PASSWORD=password123 \
    -e DOCKER_INFLUXDB_INIT_ORG=my-org \
    -e DOCKER_INFLUXDB_INIT_BUCKET=my-bucket \
    influxdb

Note: don't forget to change admin password, organization and bucket name. The password should be 8 characters or longer.

Testing InfluxDB

Open a web browser and go to http://<IP_ADDRESS>:8086, where <IP_ADDRESS> is the IP address of the system. Log in to the dashboard with the admin username and password.

Uninstall InfluxDB

To completely remove InfluxDB, remove its container:

docker rm --force influxdb

Remove InfluxDB image:

docker rmi influxdb

You can also remove InfluxDB data and configuration:

sudo rm -rf /opt/influxdb

If a user-defined bridge network was created, you can delete it as follows:

docker network rm app-net
