Docker Compose – adding identifier to network name

If you have docker-compose create the network, it will determine the name itself. Normally, it looks at the name of the directory where docker-compose.yml is located, and uses that as a prefix. Based on the name you have shown, it appears that this docker-compose.yml file is in a directory named dockercompose1163770330. It combines this with the myNetwork name you specified, and creates a network named dockercompose1163770330_myNetwork.

If you want to control the exact name of the network, you have two options.

1. Use a network created outside of docker-compose (an “external” network).

networks:
  default:
    external:
      name: myNetwork

This implies something else has created the network already. If you don’t have such a network already, creating it is easy.

docker network create myNetwork

2. (If possible) determine how visual-studio names it paths, and change that path to something static. Whether this is possible, or how, I have no idea. But if you can control dockercompose1163770330 and make it something different that you prefer, then you can predict the network name created from it.
