I've moved the setting-up-docker bits into a separate page, but have left it out the TOC. I'm not sure that level of detail on docker belongs in this section; perhaps it could move to an appendix?

## Configure Docker
|
|
|
|
Ensure docker is actually installed in your server instance.
|
|
|
|
=== "DNF based systems"
|
|
In Rocky, Alma, and any other DNF package manager system
|
|
|
|
```console
|
|
$ sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
|
|
$ sudo dnf update -y
|
|
$ sudo dnf install -y docker-ce docker-ce-cli containerd.io
|
|
$ sudo systemctl enable docker
|
|
```
|
|
|
|
=== "APT based systems"
|
|
|
|
In Ubuntu, Debian, and other Debial APT package management systems:
|
|
|
|
```console
|
|
$ sudo apt update
|
|
$ sudo apt install -y apt-utils docker.io
|
|
$ sudo snap install docker
|
|
```
|
|
|
|
If you get an error that `/etc/rc.d/rc.local is not marked executable` then make it executable with `sudo chmod +x /etc/rc.d/rc.local`
|
|
|
|
### Start Docker
|
|
|
|
```console
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
### Check if Docker is running
|
|
|
|
```console
|
|
$ systemctl status docker
|
|
```
|
|
|
|
### Enable Non-Root User Access
|
|
|
|
After completing Step 3, you can use Docker by prepending each command with sudo. To eliminate the need for administrative access authorization, set up a non-root user access by following the steps below.
|
|
|
|
1. Use the usermod command to add the user to the docker system group.
|
|
```console
|
|
$ sudo usermod -aG docker $USER
|
|
```
|
|
|
|
2. Confirm the user is a member of the docker group by typing:
|
|
```console
|
|
$ id $USER
|
|
```
|
|
|
|
It is a good idea to restart to make sure it is all set correctly.
