# Install Repositories

Some repositories will be needed later to install Flight tools.

On all nodes do:
```
 dnf install -y epel-release
```
-y is an option for the install command that answers yes to install confirmation messages.

Once this command has been run on every node, the cluster is ready for the next step.

# Testing

If all was successful, the added repositories will appear when running the command dnf repolist on every node. E.g. on head node:

[root@chead1 ~]# dnf repolist
repo id            repo name
appstream          CentOS Stream 8 - AppStream
baseos             CentOS Stream 8 - BaseOS
epel               Extra Packages for Enterprise Linux 8 - x86_64
epel-modular       Extra Packages for Enterprise Linux Modular 8 - x86_64
extras             CentOS Stream 8 - Extras
