Prepare the bootstrap node¶
If you require a RHEL-based bootstrap node, refer to Prerequisites.
Log in to any personal computer or VM running Ubuntu 20.04 that you will be using as the bootstrap node.
If you use a newly created VM, run:
sudo apt-get update
Install the current Docker version available for Ubuntu 20.04:
sudo apt install docker.io
USERaccess to the Docker daemon:
sudo usermod -aG docker $USER
Log off and log in again to the bootstrap node to apply the changes.
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.
