The following brings you how to achieve Traefik reverse proxy-load balancing on stand-alone Docker, hoping to give you some help in practical application. Load balancing involves more things, there are not many theories, and there are many books on the Internet. Today, we will use the accumulated experience in the industry to do an answer.

Create a connection network between Traefik and container applications

Sudo docker network create traefik-net

Download Traefik sample configuration file

Wget https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml

Edit the Traefik configuration file

Sudo cp. / traefik.sample.toml. / traefik.toml

Sudo vi. / traefik.toml

Edit the contents of the traefik.toml file:

Debug = false

LogLevel = "ERROR"

DefaultEntryPoints = ["http"]

[entryPoints]

[entryPoints.http]

Address = ": 80"

[retry]

[docker]

Endpoint = "unix:///var/run/docker.sock"

Domain = "docker.localhost"

Watch = true

ExposedByDefault = false

Usebindportip = true

SwarmMode = false

Network = "traefik-net"

Run the Traefik reverse proxy container on the host

Docker runs the Traefik command:

Docker run-d\

-- name traefik\

-p 808014 080\

-p 80:80\

-v $PWD/traefik.toml:/etc/traefik/traefik.toml\

-v / var/run/docker.sock:/var/run/docker.sock\

Traefik

5. Run Docker container application

Run the Docker container application web1:

Docker run-d\

-- name nginx\

-label "traefik.backend=nginx"\

-label "traefik.protocol=http"\

-label "traefik.port=80"\

-label "traefik.docker.network=traefik-net"\

-label "traefik.domain=abc.com"\

-label "traefik.frontend.rule=Host:web1.abc.com"\

-label "traefik.enable=true"\

Nginx

Run the Docker container application web2:

Docker run-d\

-- name httpd\

-label "traefik.backend=httpd"\

-label "traefik.protocol=http"\

-label "traefik.port=80"\

-label "traefik.docker.network=traefik-net"\

-label "traefik.domain=abc.com"\

-label "traefik.frontend.rule=Host:web2.abc.com"\

-label "traefik.enable=true"\

Httpd

Configure the client hosts host file and access the container application through the browser

Modify the C:\ Windows\ System32\ drivers\ etc\ hosts file on the Win7 client computer:

192.168.3.168 web1.abc.com

192.168.3.168 web2.abc.com

Access the container application through a browser on the client computer

Http://web1.abc.com

Http://web2.abc.com

7. View the Traefik management backend

Http://192.168.3.168:8080

Note: when running container applications, there can be no spaces around the equal sign in label!
