Introduction
Halo is a modern open-source Blog/CMS system that is powerful, easy to use, and has an active community. Using Docker to deploy Halo can greatly simplify the installation and maintenance process. This tutorial will guide you step-by-step through the entire process of deploying Halo with Docker.
Prerequisites
Before you begin, make sure you have the following software installed on your server:
- Docker: Version 19.03.0+
- Docker Compose: Version 1.25.0+
You can install them by following the official documentation.
Deployment Steps
1. Create a Working Directory
First, create a directory to store Halo’s data.
bash
mkdir ~/halo-data
cd ~/halo-data
2. Write the Docker Compose File
In the halo-data directory, create a file named docker-compose.yml and add the following content:
yaml
version: “3”
services:
halo:
image: halohub/halo:2.11
containername: halo
restart: always
networkmode: “host”
volumes:
– ./:/root/.halo2
healthcheck:
test: [“CMD-SHELL”, “curl -f http://localhost:8090/actuator/health/ping || exit 1”]
interval: 30s
timeout: 5s
retries: 5
start_period: 30s
This configuration uses the host network mode and mounts the current directory to the container’s /root/.halo2 directory for data persistence.
3. Start Halo
In the directory where docker-compose.yml is located, run the following command to start the Halo service:
bash
docker-compose up -d
Wait a few moments for the container to start up. You can check the container status using docker ps.
Access and Initialization
Now, you can access the Halo initialization page at http://YOUR_SERVER_IP:8090. Follow the on-screen instructions to create your administrator account and site information, and you can start your blogging journey!
Conclusion
With Docker, we have quickly and easily deployed a powerful Halo blog. This method not only simplifies deployment but also provides great convenience for future upgrades and migrations.
