• Getting the image
• Run the bare image
• Configuration
• Proxy server
• Match request path with regex
• Load balancing

Getting the image

docker pull nginx

Run the bare image

docker run --rm -d -p 80:80 nginx
curl localhost

You should get the Welcome to nginx web page.

Configuration

Configuration directives's hierachy:

• main context contains events and http
• http contains server
• server contains location

Loading a minimal configuration (see ./nginx.conf for details):

docker run --rm -v $(pwd)/nginx.conf:/etc/nginx/nginx.conf:ro -v $(pwd)/data:/data:ro -p80:80 nginx

Then you should be able to get:

• http://localhost
• http://localhost/images/example.png

Proxy server

See nginx-proxy.conf.

docker run --rm -v $(pwd)/nginx-proxy.conf:/etc/nginx/nginx.conf:ro -v $(pwd)/data:/data:ro -p80:80 nginx
curl localhost

Match request path with regex

See nginx-regex.conf.

docker run --rm -v $(pwd)/nginx-regex.conf:/etc/nginx/nginx.conf:ro -v $(pwd)/data:/data:ro -p80:80 nginx

• http://localhost/example.png

Load balancing

See nginx-lb.conf.

docker run --rm -d -v $(pwd)/nginx-lb.conf:/etc/nginx/nginx.conf:ro -v $(pwd)/data:/data:ro -p 80:80 nginx

Now if you keep reading from http://localhost, it will respond with these responses in round-robin order:

• hello from site 1
• hello from site 2
• hello from site 3
