Flow Enterprise only supports RedHat Enterprise Linux (RHEL) 7 and above. We require this to insure that customers have the latest OS compatibility and security updates.
To prepare RHEL 7 for installation of Docker, Replicated, and Flow Enterprise, it is recommended that you follow the steps outlined in this document.
Install All Updates
Bring RHEL up to the latest set of updates before beginning. This can be done with the command:
sudo yum update -y
After installing updates, reboot the system, as there may have been kernel-level updates installed.
For the installation script to go smoothly, install the following packages:
This can be done by running this command:
sudo yum install -y \
Enable Extras Repository
For things to work smoothly, it is expected that you will also enable the "extras" repository for RHEL. This can be done by executing the following command:
sudo yum-config-manager --enable rhel-7-server-extras-rpms
If you are in AWS, you will also need to execute:
sudo yum-config-manager --enable rhui-REGION-rhel-server-extras
Once you have enabled these repositories, you will need to update the yum cache appropriately:
sudo yum makecache fast
Remove Older Docker Installations
If you have previously installed docker on the server, it is recommended that you remove it. This can be done by running the commands:
sudo yum remove \
