Host Your Own Excalidraw: Real-time Whiteboarding on AlmaLinux 10

---

Excalidraw is an open-source collaborative whiteboard tool that allows teams to sketch diagrams and collaborate in real-time. Whether you're brainstorming, wireframing, or diagramming workflows, Excalidraw brings a dynamic and visual approach to teamwork.

This guide walks you through installing Excalidraw on AlmaLinux 10 using Docker.

Install Docker on AlmaLinux 10

---

Docker allows you to containerize and run applications in isolated environments. To install Docker on AlmaLinux 10:

Enable Docker repository

dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Install Docker Engine

dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Start and Enable Docker

systemctl start docker
systemctl enable docker

Verify Docker Installation

docker --version

Output:

[root@vps ~]# docker --version
Docker version 28.2.2, build e6534b4

Run Excalidraw using Docker

---

Pull the latest Excalidraw image:

docker pull docker.io/excalidraw/excalidraw:latest

Then run the container in detached mode:

docker run -d -p 8080:80 docker.io/excalidraw/excalidraw:latest

This maps port 8080 on your server to port 80 inside the container.

Access Excalidraw: Open your browser and visit:

http://your_server_ip:8080

Replace your_server_ip with your actual AlmaLinux 10 server's IP address.

You should see the Excalidraw interface and be ready to start sketching and collaborating.
