Linux and macOS

Deploy the ClearML Server in Linux or macOS using the pre-built Docker image.

For ClearML docker images, including previous versions, see However, pulling the ClearML Docker image directly is not required. ClearML provides a docker-compose YAML file that does this. The docker-compose file is included in the instructions on this page.

For information about upgrading ClearML Server in Linux or macOS, see here.


If ClearML Server is being reinstalled, clearing browser cookies for ClearML Server is recommended. For example, for Firefox, go to Developer Tools > Storage > Cookies, and for Chrome, go to Developer Tools > Application > Cookies, and delete all cookies under the ClearML Server URL.


For Linux users only:

  • Linux distribution must support Docker. For more information, see the Docker documentation.
  • Be logged in as a user with sudo privileges.
  • Use bash for all command-line instructions in this installation.
  • The ports 8080, 8081, and 8008 must be available for the ClearML Server services.



By default, ClearML Server launches with unrestricted access. To restrict ClearML Server access, follow the instructions in the Security page.

Memory Requirement

Deploying the server requires a minimum of 4 GB of memory, 8 GB is recommended.

To launch ClearML Server on Linux or macOS:

  1. Install Docker. The instructions depend upon the operating system:

  2. Verify the Docker CE installation. Execute the command:

    docker run hello-world

    The expected is output is:

    Hello from Docker!
    This message shows that your installation appears to be working correctly.
    To generate this message, Docker took the following steps:

    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64)
    3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
  3. For macOS only, increase the memory allocation in Docker Desktop to 8GB.

    1. In the top status bar, click the Docker icon.
    2. Click Preferences > Resources > Advanced, and then set the memory to at least 8192.
    3. Click Apply.
  4. For Linux only, install docker-compose. Execute the following commands (for more information, see Install Docker Compose in the Docker documentation):

    sudo curl -L "$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    sudo chmod +x /usr/local/bin/docker-compose
  5. Increase vm.max_map_count for Elasticsearch in Docker. Execute the following commands, depending upon the operating system:

    • Linux:

      echo "vm.max_map_count=262144" > /tmp/99-clearml.conf
      sudo mv /tmp/99-clearml.conf /etc/sysctl.d/99-clearml.conf
      sudo sysctl -w vm.max_map_count=262144
      sudo service docker restart
    • macOS:

      docker run --net=host --ipc=host --uts=host --pid=host --privileged --security-opt=seccomp=unconfined -it --rm -v /:/host alpine chroot /host
      sysctl -w vm.max_map_count=262144
  6. Remove any previous installation of ClearML Server.

    This clears all existing ClearML SDK databases.

    sudo rm -R /opt/clearml/
  7. Create local directories for the databases and storage.

    sudo mkdir -p /opt/clearml/data/elastic_7
    sudo mkdir -p /opt/clearml/data/mongo_4/db
    sudo mkdir -p /opt/clearml/data/mongo_4/configdb
    sudo mkdir -p /opt/clearml/data/redis
    sudo mkdir -p /opt/clearml/logs
    sudo mkdir -p /opt/clearml/config
    sudo mkdir -p /opt/clearml/data/fileserver
  8. For macOS only do the following:

    1. Open the Docker app.

    2. Select Preferences.

    3. On the File Sharing tab, add /opt/clearml.

  9. Grant access to the Dockers, depending upon the operating system.

    • Linux:

      sudo chown -R 1000:1000 /opt/clearml
    • macOS:

      sudo chown -R $(whoami):staff /opt/clearml
  10. Download the ClearML Server docker-compose YAML file.

    sudo curl -o /opt/clearml/docker-compose.yml
  11. For Linux only, configure the ClearML Agent Services:

    • Set CLEARML_AGENT_ACCESS_KEY and CLEARML_AGENT_SECRET_KEY with confidential strings for the services agent to authenticate with the API server. Provide string values.

    • If CLEARML_HOST_IP is not provided, then ClearML Agent Services uses the external public address of the ClearML Server

    • Set CLEARML_AGENT_GIT_USER / CLEARML_AGENT_GIT_PASS so ClearML Agent Services can access private repositories for running service tasks

    export CLEARML_AGENT_ACCESS_KEY=generate_access_key_here
    export CLEARML_AGENT_SECRET_KEY=generate_secret_key_here
    export CLEARML_HOST_IP=server_host_ip_here
    export CLEARML_AGENT_GIT_USER=git_username_here
    export CLEARML_AGENT_GIT_PASS=git_password_here
  12. Run docker-compose with the downloaded configuration file.

    docker-compose -f /opt/clearml/docker-compose.yml up -d

The server is now running on http://localhost:8080.

Port Mapping

After deploying ClearML Server, the services expose the following ports:

  • Web server on port 8080
  • API server on port 8008
  • File server on port 8081


To restart ClearML Server Docker deployment:

  • Stop and then restart the Docker containers by executing the following commands:

    docker-compose -f /opt/clearml/docker-compose.yml down
    docker-compose -f /opt/clearml/docker-compose.yml up -d

Backing Up and Restoring Data and Configuration


Stop your server before backing up or restoring data and configuration

The commands in this section are an example of how to back up and to restore data and configuration.

If the data and configuration folders are in /opt/clearml, then archive all data into ~/clearml_backup_data.tgz, and configuration into ~/clearml_backup_config.tgz:

sudo tar czvf ~/clearml_backup_data.tgz -C /opt/clearml/data .
sudo tar czvf ~/clearml_backup_config.tgz -C /opt/clearml/config .

If needed, restore data and configuration by doing the following:

  1. Verify the existence of backup files.

  2. Replace any existing data with the backup data:

    sudo rm -fR /opt/clearml/data/* /opt/clearml/config/*
    sudo tar -xzf ~/clearml_backup_data.tgz -C /opt/clearml/data
    sudo tar -xzf ~/clearml_backup_config.tgz -C /opt/clearml/config
  3. Grant access to the data, depending upon the operating system:

    • Linux:

      sudo chown -R 1000:1000 /opt/clearml
    • macOS:

      sudo chown -R $(whoami):staff /opt/clearml

Next Step

To keep track of your experiments and/or data, the clearml package needs to communicate with your server. For instruction to connect the ClearML SDK to the server, see Getting Started: First Steps.
