Installation Guide

A CVAT installation guide for different operating systems.

Quick installation guide

Before you can use CVAT, you’ll need to get it installed. The document below contains instructions for the most popular operating systems. If your system is not covered by the document it should be relatively straightforward to adapt the instructions below for other systems.

Probably you need to modify the instructions below in case you are behind a proxy server. Proxy is an advanced topic and it is not covered by the guide.

For access from China, read sources for users from China section.

Ubuntu 22.04/20.04 (x86_64/amd64)

Open a terminal window. If you don’t know how to open a terminal window on Ubuntu please read the answer.

Type commands below into the terminal window to install Docker and Docker Compose. More instructions can be found here.

sudo apt-get update
sudo apt-get --no-install-recommends install -y \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \
  stable"
sudo apt-get update
sudo apt-get --no-install-recommends install -y \
  docker-ce docker-ce-cli containerd.io docker-compose-plugin

(Optional) To avoid prefacing Docker commands with sudo, you can perform the post-installation steps. This involves creating a Unix group named docker and adding your current user to this group.
```
sudo groupadd docker
sudo usermod -aG docker $USER
```
Log out and log back in (or reboot) so that your group membership is re-evaluated. You can type groups command in a terminal window after that and check if docker group is in its output.
Clone CVAT source code from the GitHub repository with Git.

Following command will clone the latest develop branch:
```
git clone https://github.com/cvat-ai/cvat
cd cvat
```
See alternatives if you want to download one of the release versions or use the wget or curl tools.
To access CVAT over a network or through a different system, export CVAT_HOST environment variable
```
export CVAT_HOST=FQDN_or_YOUR-IP-ADDRESS
```
Run docker containers. It will take some time to download the latest CVAT and other required images like postgres, redis, and start containers.
```
docker compose up -d
```
(Optional) Use CVAT_VERSION environment variable to specify the version of CVAT you want to install specific version (e.g v2.1.0, dev). Default behavior: dev images will be pulled for develop branch, and corresponding release images for release versions.
```
CVAT_VERSION=dev docker compose up -d
```
Alternative: if you want to build the images locally with unreleased changes see How to pull/build/update CVAT images section
You can register a user but by default, it will not have rights even to view the list of tasks. Thus you should create a superuser. The superuser can use an admin panel to assign the correct groups to the user. Please use the command below:
```
docker exec -it cvat_server bash -ic 'python3 ~/manage.py createsuperuser'
```
Choose a username and a password for your admin account. For more information please read Django documentation.

Google Chrome is the only browser that is supported by CVAT. You need to install it as well. Type commands below in a terminal window:

curl https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
sudo apt-get update
sudo apt-get --no-install-recommends install -y google-chrome-stable

Open the installed Google Chrome browser and go to localhost:8080. Type your login/password for the superuser on the login page and press the Login button. Now you should be able to create a new annotation task. Please read the CVAT manual for more details.

Windows 10

Install Git on your system if it’s not already installed
- Ubuntu:
```
sudo apt-get --no-install-recommends install -y git
```
- Windows: Follow instructions from https://git-scm.com/download/win
Clone CVAT source code from the GitHub repository.

The command below will clone the default branch (develop):
```
git clone https://github.com/cvat-ai/cvat
cd cvat
```
To clone specific tag, e.g. v2.1.0:
```
git clone -b v2.1.0 https://github.com/cvat-ai/cvat
cd cvat
```

Wget (Linux, Mac)

To download latest develop branch:

wget https://github.com/cvat-ai/cvat/archive/refs/heads/develop.zip
unzip develop.zip && mv cvat-develop cvat
cd cvat

To download specific tag:

wget https://github.com/cvat-ai/cvat/archive/refs/tags/v1.7.0.zip
unzip v1.7.0.zip && mv cvat-1.7.0 cvat
cd cvat

Curl (Linux, Mac)

curl -LO https://github.com/cvat-ai/cvat/archive/refs/heads/develop.zip
unzip develop.zip && mv cvat-develop cvat
cd cvat

To download specific tag:

curl -LO https://github.com/cvat-ai/cvat/archive/refs/tags/v1.7.0.zip
unzip v1.7.0.zip && mv cvat-1.7.0 cvat
cd cvat

CVAT healthcheck command

The following command allows testing the CVAT container to make sure it works.

docker exec -t cvat_server python manage.py health_check

The expected output of a healthy CVAT container:

Cache backend: default   ... working
DatabaseBackend          ... working
DiskUsage                ... working
MemoryUsage              ... working
MigrationsHealthCheck    ... working
OPAHealthCheck           ... working

Deploying CVAT behind a proxy

If you deploy CVAT behind a proxy and do not plan to use any of serverless functions for automatic annotation, the exported environment variables http_proxy, https_proxy and no_proxy should be enough to build images. Otherwise please create or edit the file ~/.docker/config.json in the home directory of the user which starts containers and add JSON such as the following:

{
  "proxies": {
    "default": {
      "httpProxy": "http://proxy_server:port",
      "httpsProxy": "http://proxy_server:port",
      "noProxy": "*.test.example.com,.example2.com"
    }
  }
}

These environment variables are set automatically within any container. Please see the Docker documentation for more details.

Using the Traefik dashboard

If you are customizing the docker compose files and you come upon some unexpected issues, using the Traefik dashboard might be very useful to see if the problem is with Traefik configuration, or with some of the services.

You can enable the Traefik dashboard by uncommenting the following lines from docker-compose.yml

services:
  traefik:
    # Uncomment to get Traefik dashboard
    #   - "--entryPoints.dashboard.address=:8090"
    #   - "--api.dashboard=true"
    # labels:
    #   - traefik.enable=true
    #   - traefik.http.routers.dashboard.entrypoints=dashboard
    #   - traefik.http.routers.dashboard.service=api@internal
    #   - traefik.http.routers.dashboard.rule=Host(`${CVAT_HOST:-localhost}`)

and if you are using docker-compose.https.yml, also uncomment these lines

services:
  traefik:
    command:
      # Uncomment to get Traefik dashboard
      # - "--entryPoints.dashboard.address=:8090"
      # - "--api.dashboard=true"

Note that this “insecure” dashboard is not recommended in production (and if your instance is publicly available); if you want to keep the dashboard in production you should read Traefik’s documentation on how to properly secure it.

Additional components

Semi-automatic and automatic annotation

Please follow this guide.

Stop all containers

The command below stops and removes containers and networks created by up.

docker compose down

Use your own domain

If you want to access your instance of CVAT outside of your localhost (on another domain), you should specify the CVAT_HOST environment variable, like this:

export CVAT_HOST=<YOUR_DOMAIN>

You can use shared storage for uploading data when you create a task. To do that, you must mount the shared storage to the CVAT docker container. Example of docker-compose.override.yml for this purpose:

services:
  cvat_server:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_import:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_export:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_annotation:
    volumes:
      - cvat_share:/home/django/share:ro

volumes:
  cvat_share:
    driver_opts:
      type: none
      device: /mnt/share
      o: bind

You can change the share device path to your actual share.

You can mount your cloud storage as a FUSE and use it later as a share.

Email verification

You can enable email verification for newly registered users. Specify these options in the settings file to configure Django allauth to enable email verification (ACCOUNT_EMAIL_VERIFICATION = ‘mandatory’). Access is denied until the user’s email address is verified.

ACCOUNT_AUTHENTICATION_METHOD = 'username_email'
ACCOUNT_CONFIRM_EMAIL_ON_GET = True
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_EMAIL_VERIFICATION = 'mandatory'

# Email backend settings for Django
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

Also, you need to configure the Django email backend to send emails. This depends on the email server you are using and is not covered in this tutorial, please see Django SMTP backend configuration for details.

Deploy CVAT on the Scaleway public cloud

Please follow this tutorial to install and set up remote access to CVAT on a Scaleway cloud instance with data in a mounted object storage bucket.

Deploy secure CVAT instance with HTTPS

Using Traefik, you can automatically obtain a TLS certificate for your domain from Let’s Encrypt, enabling you to use HTTPS protocol to access your website.

To enable this, first set the CVAT_HOST (the domain of your website) and ACME_EMAIL (contact email for Let’s Encrypt) environment variables:

export CVAT_HOST=<YOUR_DOMAIN>
export ACME_EMAIL=<YOUR_EMAIL>

Then, use the docker-compose.https.yml file to override the base docker-compose.yml file:

docker compose -f docker-compose.yml -f docker-compose.https.yml up -d

In the firewall, ports 80 and 443 must be open for inbound connections from any

Then, the CVAT instance will be available at your domain on ports 443 (HTTPS) and 80 (HTTP, redirects to 443).

Deploy CVAT with an external database

By default, docker compose up will start a PostgreSQL database server, which will be used to store CVAT’s data. If you’d like to use your own PostgreSQL instance instead, you can do so as follows. Note that CVAT only supports the same major version of PostgreSQL as is used in docker-compose.yml.

First, define environment variables with database connection settings:

export CVAT_POSTGRES_HOST=<PostgreSQL hostname> # mandatory
export CVAT_POSTGRES_PORT=<PostgreSQL port> # defaults to 5432
export CVAT_POSTGRES_DBNAME=<PostgreSQL database name> # defaults to "cvat"
export CVAT_POSTGRES_USER=<PostgreSQL role name> # defaults to "root"
export CVAT_POSTGRES_PASSWORD=<PostgreSQL role password> # mandatory

Then, add the docker-compose.external_db.yml file to your docker compose up command:

docker compose -f docker-compose.yml -f docker-compose.external_db.yml up -d

How to pull/build/update CVAT images

For a CVAT version lower or equal to 2.1.0, you need to pull images using docker because the compose configuration always points to the latest image tag, e.g.
```
docker pull cvat/server:v1.7.0
docker tag cvat/server:v1.7.0 openvino/cvat_server:latest

docker pull cvat/ui:v1.7.0
docker tag cvat/ui:v1.7.0 openvino/cvat_ui:latest
```
For CVAT version more than v2.1.0 it’s possible to pull specific version of prebuilt images from DockerHub using CVAT_VERSION environment variable to specify the version (e.g. dev):
```
CVAT_VERSION=dev docker compose pull
```
To build images yourself include docker-compose.dev.yml compose config file to docker compose command. This can be useful if you want to build a CVAT with some source code changes.
```
docker compose -f docker-compose.yml -f docker-compose.dev.yml build
```

To update local images to latest or dev tags run:

CVAT_VERSION=dev docker compose pull

CVAT_VERSION=latest docker compose pull

Troubleshooting

Sources for users from China

If you stay in China, for installation you need to override the following sources.

For use apt update using:

Ubuntu mirroring help

Pre-compiled packages:

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

Or source packages:

deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

Docker mirror station

Add registry mirrors into daemon.json file:

{
  "registry-mirrors": [
    "http://f1361db2.m.daocloud.io",
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com",
    "https://mirror.ccs.tencentyun.com"
  ]
}

For using pip:

PyPI mirroring help

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

For using npm:

npm mirroring help

npm config set registry https://registry.npm.taobao.org/

Instead of git using gitee:

CVAT repository on gitee.com

For replace acceleration source docker.com run:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \

For replace acceleration source google.com run:

curl https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

HTTPS is not working because of a certificate

If you’re having trouble with an SSL connection, to find the cause, you’ll need to get the logs from traefik by running:

docker logs traefik

The logs will help you find out the problem.

If the error is related to a firewall, then:

Open ports 80 and 443 for inbound connections from any.
Delete acme.json. The location should be something like: /var/lib/docker/volumes/cvat_cvat_letsencrypt/_data/acme.json.

After acme.json is removed, stop all cvat docker containers:

docker compose -f docker-compose.yml -f docker-compose.https.yml down

Make sure variables set (with your values):

export CVAT_HOST=<YOUR_DOMAIN>
export ACME_EMAIL=<YOUR_EMAIL>

and restart docker:

docker compose -f docker-compose.yml -f docker-compose.https.yml up -d
