Setup Ngix and docker

Posted on Edited on In ,

今天我想要分享用 UBUNTU 架設 ngix http server,同時我也會用 docker 方式安裝。

NGIX Setup ubuntu

Step1. Install Nginx

1
sudo apt install nginx -y

Step2. show nginx status

Verify Nginx is Running show statusd

1
sudo systemctl status nginx

Step3: Firewall setting

1
2
sudo ufw allow 'Nginx HTTP'
sudo ufw reload

Step4 Navigate browser to test Nginx

please navigate your web browser using your local IP it should occur index page

1

3
http://172.21.201.250
or
http://127.0.0.1

It will look like this, http web server is setup success

Step5 (optional) Index to show like file management

  • change permission
1
sudo chmod 644 /var/www/html/
  • edit configure setting

sudo nano /etc/nginx/sites-available/default
    location / {
        try_files $uri $uri/ =404;
        autoindex on; # <--- Add this line
    }
  • reload configure

Test Nginx configuration for syntax errors:

1
sudo nginx -t

Reload Nginx to apply changes

1
sudo systemctl reload nginx
  • rename index.html to any other file type
1
sudo mv /var/www/html/index.nginx-debian.html /var/www/html/index.nginx-debian.html.bak

NGIX Docker Setup

Ubuntu version: 20.04

Step1 Install docker and enable services after boot

sudo apt update
sudo apt install docker.io -y
sudo systemctl start docker
sudo systemctl enable docker
sudo usermod -aG docker chenchih # Add your user to the docker group
# Remember to log out and log back in (or reboot) for the group change to take effect

Test docker 測試 Docker

1
docker run hello-world

Pull ngix package

1
2
#Pull or Run Nginx in Docker
docker pull nginx:latest

Run Nginx Container

Run the Nginx Container with this option:

  • --name my-nginx: Gives your container a memorable name.
  • -p 8080:80: Port mapping. Your Pi’s 8080 will point to the container’s 80.
  • -d: Detached mode (runs in the background).
  • nginx:latest: The image to use.
1
docker run --name my-nginx -p 8080:80 -d nginx:latest

Check Container running?

Note: You always use an image to create a container, so I will show how to list image and container.

  • List and verify the Container is Running:
1
docker ps -a # Lists all containers, including  stopped items
  • Shows all the local images
1
docker images

The docker images command is used to list all the Docker images you have downloaded or built on your local machine. The images will be pull into this path: /var/lib/docker/, is the default storage location for all Docker data on Linux, not just images. This includes:

  • Images: The layers of all images you have pulled or built.
  • Containers: The writable layers of your running containers.
  • Volumes: The data for any named volumes you’ve created.
  • Networks: Configuration data for your Docker networks.

Access the Nginx Web Server

You can access http://localhost:8080 or instead use your IP address like http://<your_pi_ip_address>:8080 it will look like below:

Stop and remove the Container (Cleanup)

1
2
docker stop my-nginx # Stops the running container
docker rm my-nginx # Removes the container instance

check docker with docker ps -a will now show it’s gone.

Remove the downloaded image (to free space)

1
docker rmi nginx:latest

Docker command summary

  • docker ps -a: Show me all my containers (running or stopped).
  • docker rm <container_name_or_id>: Please remove this specific container instance for me.
  • docker images: Show me all the image blueprints I have downloaded.
  • docker rmi <image_name:tag_or_id>: Please remove this specific image blueprint from my local storage.
