Install Docker CE and Docker compose on RHEL 8 or RHEL 9 using dnf commands

Before you begin: You need a valid Red Hat subscription and account credentials to perform these actions.

To install Docker CE and Docker compose on RHEL 8:

Add a subscription on a RHEL 8 system. To do that, complete the following steps:
1. Register the system:
```
sudo subscription-manager register
```
  This command prompts you to enter your Red Hat account credentials. After successful registration, the system is associated with your Red Hat account.
2. Refresh:
```
sudo subscription-manager refresh
```
  This command manually refreshes the local system's subscription information.
3. Attach a subscription:
```
sudo subscription-manager attach --auto
```
  This command automatically attaches available subscriptions to your system.

Add the external repository by running the following command.
```
sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
```
1. Verify whether the repository has been enabled. To do that, run the following command that returns detailed information about all the enabled repositories.
```
sudo dnf repolist -v
```
Install docker-ce with the --nobest option. With this option, the first version of docker-ce with satisfiable dependencies is selected as the "fallback" version.
```
sudo dnf install --nobest docker-ce
```

Install the latest available containerd.io package manually

sudo dnf install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm

Install the latest docker-ce version:
```
sudo dnf install docker-ce
```
Start and enable the docker daemon
```
sudo systemctl enable --now docker
```
1. Confirm whether the daemon is active by running this command:
```
systemctl is-active docker
```

Install docker-compose globally.

Download the binary file from the project’s GitHub page:

curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o docker-compose

After the binary file is downloaded, move it to the /usr/local/bin folder, and then make it executable:

sudo mv docker-compose /usr/local/bin && sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
