    Install Docker Community Edition on Cortex XSOAR

    Follow these instructions to install Docker CE.
    It is recommended that you install Docker Enterprise Edition (EE), but it is still possible to install Docker Community Edition (CE). These instructions assume a clean Enterprise Linux installation without Docker EE.
    Before you begin:
    • Ensure that you have the recommended storage drivers for
      devicemapper
       and
      vfs
      .
    • Check the kernel version.
      You must have Linux kernel 3.10 or above. To check your kernel version, run the following command:
      $ uname -r
4.1.12-124.24.1.el7uek.x86_64
    • Update Container-Selinux if you receive the
      Requires: container-selinux >= 2.9
       message.
    1. Run the following commands:
      • sudo yum install -y yum-utils
      • sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
      • sudo yum install -y --setopt=obsoletes=0 --nobest docker-ce
    2. After installation, start Docker daemon to fetch images during installation by running the following command:
      systemctl start docker
    3. Install Cortex XSOAR.
    4. (
      Optional
      ) If you are using Docker for an Engine, Install an Engine.
    5. Run the following commands:
      • sudo usermod -aG docker demisto
      • systemctl restart docker
