Introduction to Docker and Caddy
Docker is an open source platform that allows developers to package applications and their dependencies to form a lightweight container. This way, the application can be consistent in any environment, reducing the worries of "running on my computer". Caddy is a modern HTTP/2 server that automatically provides you with HTTPS, which is simple to configure and is suitable for rapid deployment and development.
This experiment uses Sanfeng Cloud's free server, configured with a 1-core CPU, 1G memory and 5M bandwidth. This configuration is relatively suitable in this experiment, and the overall experience is acceptable.
Detailed steps to deploy a Caddy server on Ubuntu via Docker
Step 1: Install Docker
First, make sure Docker is installed on your Ubuntu system. You can use the following command to install:
sudo apt update sudo apt install -y
Step 2: Start Docker Service
After the installation is complete, start the Docker service and set it to power on and start:
sudo systemctl start docker sudo systemctl enable docker
Step 3: Pull the Caddy image
Next, pull the Docker image of Caddy:
sudo docker pull caddy:latest
Step 4: Create a Caddyfile configuration file
Create a name calledCaddyfile
The configuration file, the content is as follows (adjusted according to your needs):
:80 { respond "Hello, World!" 200 }
Step 5: Run the Caddy container
Use the following command to start the Caddy server and make sureCaddyfile
Replace the path with your actual path:
sudo docker run -d -p 80:80 --name my_caddy -v /path/to/Caddyfile:/etc/caddy/Caddyfile caddy:latest
Parameter description
-
-d
: Run containers in the background. -
-p 80:80
: Map port 80 of the host to port 80 of the container. -
--name my_caddy
: Assign a name to the container. -
-v /path/to/Caddyfile:/etc/caddy/Caddyfile
: Mount the localCaddyfile
Into the container.
Step 6: Verify the Caddy Server
Open the browser and accesshttp://your server IP
, if you see "Hello, World!", it means that the Caddy server has been running successfully.
Summarize
Through the above steps, you have successfully deployed the Caddy server through Docker on Ubuntu system. This process is simple and efficient, suitable for rapid development and testing. Hope this tutorial helps you!
