This article mainly introduces the docker compose container interconnection method related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you will get something after reading this docker compose container interconnection method article, let's take a look at it.

Haproxy connects to nginx container

The key point is how to configure how containers are connected to each other.

1, first specify the service name in the compose file. Then configure links

2, specify the name of the service in the configuration file

Some knowledge of docker-compose configuration file #

Network_mode: set network mode network_mode: "bridge" network_mode: "host" network_mode: "none" network_mode: "service: [service name]" network_mode: "container: [container name/id]" links: connect the specified container to the current connection. You can set an alias. Avoid container restart caused by ip cannot be connected dynamically links: # specify service name: alias-docker-compose-eureka-server:compose-eureka update container: when the configuration of the service changes, you can use the docker-compose up command to update the configuration. At this time, Compose will delete the old container and create a new container. The new container will join the network with a different IP address, and the name will remain the same. Any connection to the old container will be closed, and the new container can be found again and connected to the links service. Links services can access each other using service names, and links allows you to define an alias to access other services version: '2'services: web: build:.
