Prerequisites¶

Before you start with bootstrapping the OpenStack-based management cluster, complete the following prerequisite steps:

1. Verify that your planned cloud meets the reference hardware bill of material and software requirements as described in Requirements for an OpenStack-based cluster.

2. Configure the bootstrap node:

   1. Log in to any personal computer or VM running Ubuntu 18.04 that you will be using as the bootstrap node.

   2. If you use a newly created VM, run:

      sudo apt-get update
      

   3. Install the current Docker version available for Ubuntu 18.04:

      sudo apt install docker.io
      

   4. Grant your USER access to the Docker daemon:

      sudo usermod -aG docker $USER
      

   5. Log off and log in again to the bootstrap node to apply the changes.

   6. Verify that Docker is configured correctly and has access to Container Cloud CDN. For example:

      docker run --rm alpine sh -c "apk add --no-cache curl; \
      curl https://binary.mirantis.com"
      

      The system output must contain no error records. In case of issues, follow the steps provided in Troubleshooting.

      Note

      If you require all Internet access to go through a proxy server for security and audit purposes, configure Docker proxy settings as described in the official Docker documentation.

3. Proceed to Bootstrap a management cluster.
