This guide will help you to install and start ThingsBoard Edge using Docker on Linux or Mac OS.
Prerequisites
ThingsBoard Cloud server
To start using ThingsBoard Edge you need to have ThingsBoard server that supports edge functionality up and running.
The easiest way is to use Live Demo server.
The alternative option is to install ThingsBoard Community Edition server that supports edge functionality on-premise.
Please visit Install CE to install 3.3 version or higher of server that supports edge functionality.
Edge provision on cloud
Additionally, you will need to provision ThingsBoard Edge on cloud server. Please follow Step 1 first if you skipped it.
Once ThingsBoard Edge provisioned on cloud server please follow installation steps below.
Docker installation
Edge hardware requirements
Hardware requirements depend on an amount of devices connected to the edge and GUI usage locally.
To run ThingsBoard Edge without heavily usage of GUI (local dashboards, device management etc.) and relatively small amount of devices (under 100) on a single machine you will need at least 1GB of RAM.
To run ThingsBoard Edge with heavily usage of GUI (local dashboards, device management etc.) and with 100+ devices on a single machine we recommend having at least 4GB of RAM.
Step 1. Running ThingsBoard Edge
Here you can find ThingsBoard Edge docker image:
Create docker compose file for ThingsBoard Edge service:
1
nano docker-compose.yml
Add the following lines to the yml file:

- mounts the host’s dirmytb-edge-logs
to ThingsBoard Edge logs directory;-

Run following commands, before starting docker container(s), to create folders for storing data and logs. These commands additionally will change owner of newly created folders to docker container user. To do this (to change user) chown command is used, and this command requires sudo permissions (command will request password for a sudo access):
1
2
mkdir -p ~/.mytb-edge-data && sudo chown -R 799:799 ~/.mytb-edge-data
mkdir -p ~/.mytb-edge-logs && sudo chown -R 799:799 ~/.mytb-edge-logs
NOTE: Replace directory ~/.mytb-edge-data and ~/.mytb-edge-logs with directories you’re planning to use in docker-compose.yml
.
Set the terminal in the directory which contains the docker-compose.yml
file and execute the following commands to up this docker compose directly:
1
2
docker compose up -d
docker compose logs -f mytbedge
Step 2. Open ThingsBoard Edge UI
Once started, you will be able to open ThingsBoard Edge UI using the following link http://localhost:8080.
Please use your tenant credentials from local cloud instance or ThingsBoard Live Demo to log in to the ThingsBoard Edge.
Step 3. Detaching, stop and start commands
You can detach from session terminal using Ctrl-p
Ctrl-q
key sequence - the container will keep running in the background.
In case of any issues you can examine service logs for errors. For example to see ThingsBoard Edge container logs execute the following command:
1
docker compose logs -f mytbedge
To stop the container:
1
docker compose stop mytbedge
To start the container:
1
docker compose start mytbedge
Troubleshooting
DNS issues
NOTE If you observe errors related to DNS issues, for example
1
127.0.1.1:53: cannot unmarshal DNS message
You may configure your system to use Google public DNS servers. See corresponding Linux and Mac OS instructions.
Database issues
NOTE If you see errors related to edge is not able to connect to database, for example
